Hows This for Custom Turbo better than the Garrett! IHI 5 Stage 4 turbo Rated at over 300bhp but will be running on my little 500 around the 250mark :)
-
looks similer to mine
-
Yours the TMC version tho?
-
yes
so what else are you changing apart from the turbo to get 250
you need
different boost sensors
new injectors
big inter cooler
new exhaust
and a good induction kit
and how much boost are you going to run
-
its only better to run a bigger turbo significantly under its potential when you're tracking the car as you'll benefit from lower boost and therefore lower temperatures helping efficiency and reliability while also being able to keep the revs up and the turbo spooled - on the road however the bigger turbo will mean increased lag and a higher boost threshold - dont confuse those 2 terms - either build the engine so you can make the most of the bigger turbo or run a smaller turbo nearer its maximum potential - allowing better response/lower boost threshold - the increased heat generated from running a turbo nearer its maximum is an acceptable tradeoff as what isnt used in huge amounts on the road especially at that power level. -
Dan - unless your engine has forged/strengthened internals or is running methanol 250hp on standard pistons will melt something especially once the weather begins to get warmer
-
what has somehow morphed into what - what meaning wide open throttle
-
read what as wide open throttle - it keeps changing what i want i type
-
I think the spell checker is changing it for you.
-
it actually works then does it - it must have been on its holidays for a considerable amount of time judging by some of the efforts of forum members :p - but yes i assumed as much, i just wanted to make sure what i typed could be understood
-
mine is running 1.5 bar of boost the standard internals are safe up to 1.6 bar
with the forged piston and rods and cams it can be turned up to 1.8 bar safely
so that should be close to 300hp
if that is more than the car can handle i can turn it down to maybe 1.65bar and run it safe
as for how it drives on the road it is far better than when it had the ihi turbo
with the ihi turbo i got 242ftlb at to low a rpm for the car to put down now it only makes 240ftlb but it makes it at higher revs and the car is better for it
as it builds power smoothly all the way to the red line
insted of making all the power by 4000rpm and then running out of puff
so in conclusion for me the bigger turbo is perfect you can drive it round town like its a 1.4 non turbo and when you having fun and use all the revs it is just as fast as a astra vxr
i mean come on the ihi has a power band from 2000 to 4000rpm when you a driving fast how often are you that far down the rpm range
my turbo starts to spool at 2800rpm and makes full boost by 3400 and makes it all the way to the red line
it is perfect for on the motor way all i have to do is scweeze the throttle and boost builds and you get pushed back in to you seat
and my 7.5l inter cooler will help keep things cool
-
i perhaps wasnt making myself clear Dan - when i was talking about running a smaller turbo hard as opposed to a bigger turbo within itself i was referring to the OP's turbo - he said the IHI was rated for 300 hp and he would be running it at 250hp - i was saying that instead of getting a turbo rated for 300 and running it at 250 get a turbo like yours rated for 260 and run it at 250 - you will still achieve target power with a turbo that wil be more responsive - i wasn't comparing your turbo to the stock IHI - which is good for pottering around on the road but when the pace is upped it is found wanting -
I assume the turbo TMC fittied for you is GTT's one? - if it is you wont get 300 hp - lagerlout os barely achieving that with a GT25/28 hybrid and a host of other modifications - instead of building the engine i would just fit GTT's powermist kit run a bit more boost and you'll have pretty much the optimum balance between performance/reliability/drivability/cost
-
will be interesting how much power I be getting with mine after rebuild
-GT2530
-G-Tech Forged piston & ConRod
-700cc injectors
-Aftermarket Cams
-Valve and spring
-Forged intercooler
-BMC OTA
-Motec M400 ecu
-
I haven't just changed the turbo and i did look at the GT20/25 conversion but the turbo which i got built for me i have been told its better than that and with no Lag its just IHI 5 housing with different parts 360 ball bearings and some other parts i dont quite understand lol, Also iv got a Larger Front mounted Intercooler, Induction Kit is the Sanspeed one but Customised to draw the cold in from where the old intercoolers were, Exhaust staying the same but Decat, Uprated Drive Shaft, Uprated Clutch And the old Boost gauge taken out and Changed for a different one but in the same housing, As for bigger injectors iv told i dont need them and Same for Map sensors But its already been map by angel on the old set up and is going into AMD for two days when i get it back sometime next week to be set up again seeing as they have the rolling road and offered the best price :) and iv been told all that will make me 250 bhp and then in the summer if i still got the car i was looking at forged pistons and Nos kit just for some more fun
-
Dan that turbo is huge :o any heat shields fitted to it?
-
maybe also consider relocating the battery with a small Dry Cell under the seat. Since you dun have those stock intercooler there, when you lose the battery, you can actually draw cold air from where the intercooler was into the induction. That's what I am doing with the BMC OTA
-
would that not be too visible to eye tho and lot go big cables on show??
-
i dont see how turbos can be rated for hp as you can make
its boost pressure that my turbo is rated for my turbo is rated at 1.8 bar i am only running it at 1.5
so i am not running close to what the turbo can do
i am only doing the rods pistons and cams and some port work to the head witch should give me around 300hp
how are you going to get more fuel in as the standard ones just cant supply the fuel needed to keep the engine from turning in to a lot of small bits in the sump
-
well, i guess after the car is done. . . we can have a look on the dyno sheet
-
too be honest i just told the garage what i want from my car ie how much power and they sorted it all do is just pay the blll ;) but i know that the turbo boost was running at 2 bar and could go more hence they changing the gauge inside that bit confused me but i will check the correct figures on tuesday when hopefully its ready as for the fuel bit im just going by what the garage told me so will know then if i have to uprate the injectors its no biggie :)
-
2 bar :o 8) that should give you more than 300hp :thumb:
but the standard internals will go bang at 1.6 bar
-
Thats why i only want 250bhp and its going to AMD for two days the moment i get it back for checky £400 map and set up the boost as i haven't a clue lol
-
dan vbv how long did yours take to be done? mines almost been a month!
-
2 bar :o 8) that should give you more than 300hp :thumb:
but the standard internals will go bang at 1.6 bar
Standard internal will go bang at 1.6bar, that is true. I have proven that already, Running 2bar with the stock 1.4 with turbo that size. If it really going to happen, you probably get full boost at 5500rpm and redline at 6000rpm :thumb:
-
Im still confused on all this boost stuff, but my car was running almost 1.2/3 boost on the gauge before i had any mods due to angel remap wont it still be running the same with this new turbo before it goes to AMD??
-
a quick word of warning dan - upping the boost dosent necessarily give you a proportionate increase in power - the point of turbos is to increase the amount of air that is rammed into the engine - when you start getting near the maximum for the turbo the compressor looses its efficiency and drastically increases charge air temps thus reducing the amount of air rammed into the engine which has a negative increase in power - so while going from 1.5 bar to 1.8 bar is a 20% hike in pressure you may only be getting a 5% increase in air into the cylinders as a result of the charge air being excessively heated by the compressor starting to operate outside of its efficiency
-
yes but the turbo is ment to be run at 1.8 bar i just dont have the pistons and rods yet to run it that high
so the turbo is ment to be efficient at 1.8 bar :thumb:
Im still confused on all this boost stuff, but my car was running almost 1.2/3 boost on the gauge before i had any mods due to angel remap wont it still be running the same with this new turbo before it goes to AMD??
the standard boost gage can not be trusted for tuning but it might run the standard map but i dont know how well it will run like that and i would not want to drive it like that for long just in case
sorry if it sounds harsh but from what i can see
you will have a engine that is not going to get enough fuel and is going to be running 0.4 bar of boost more than the pistons can stand before melting :'(
but i hope you prove me wrong ;D as i have been so many times before
mine took 3 days from dropping the car of to picking it up :thumb: dropped it off on a Wednesday and picked it up on sat
-
im not meaning to sound like im picking on you but just because a turbo is specified to run at 1.8bar dosent mean its efficient at doing it - look at a compressor map and you'll have islands with %'s next to them- thats how well the compressor works at any given boost pressure - any turbo nearing its max will see a drop in efficiency - meaning an increase in boost pressure will see a less than proportionate increase in air supplied to the cylinders - but anyway i wish you well with the rest of the build - why are you building the engine as opposed to running a methanol kit? have you got any dyno graphs showing where you are at the moment - i know you've said in car footage is problematic to get but i dont think i would be the only one interested to see some
-
the reason i want a built engine instead of meth is safty if the meth fails engine could go bang and built engine i wont need to fill a second tank as i use my car every day i want to keep it user friendly
and i just with the car came like this from abarth
i have got some dyno graphs of my car car
before and after
i have lost power but i have lost it where the car does not need it and is never used in
-
appreciate the pics Dan - i think you'll find any reputable methanol kit has a fail safe that if anything were to fail the car would drop out of boost - thats a lovely looking curve with the big turbo, once the turbo is spooled holds a lovely flat torque curve and must slam into the red line - if you're gonna build the motor do what lagerlout did and bore it from 1368cc to 1.5 l - will help with off boost torque (if you ever use that) and will bring the turbo in sooner aswell as having lower cylinder pressures aiding reliability - is that the garrett that GTT originally put together
-
no its a custom one on tmc web site ment to get 230 to 240 hp
i am thinking of the big bore but
pistons and rods
fast road cams to help spool the turbo faster and hold more power at the red line
and a big bore kit to spool turbo faster
and a little bit of port work just to help all over
the only thing i dont know is with the big bore it will make the cylinder walls thiner and less strong so i am not completely sold on the big bore
-
i could do the cams soon with the over time i am working but i will be cheaper to only take the engine to bits once and do the rods and the pistons at the same time :thumb:
and it is going to have to be run in that going to be hell for me when the time comes
right dan you have now got 300 hp bit only use 1/4 throttle for 1000 miles to bed it in
but i think it will be worth it at the end of it
i need to do the brakes first witch is why i am going for brembos under some pro race 3 wheels next
after the exhaust get changed
the list goes on
-
the list goes on
Same boat :thumb:
-
Snap I've also got to do the brakes once I've finished the engine ;)
MOD: Txt speak changed
-
i have been looking at boring it out to 1.6 but i dont think the extra work involved will be worth it
and it will make it easier to blow a head gasket and make the cylinder walls thicker so
as the car is my daily driver i need it off the road as little time as posable
so the list of things to do is as follows
mm cat back exhaust
abarth brembo brakes
17inch team dynamic pro race 3 wheels in black
forged piston and rods
fast road cams
after that i think it will be a well sorted hot hatch :thumb: i just hope i can do it by the end of the year will just have to see
-
what price have you been looking at to get it bored out to 1.6? including work?
I've been quted just over £1k for the forged pistons and heads polished if i remember correctly
MOD: Txt speak changed
-
another pic I've got of the bigger intercooler as well
-
where are you getting the pistons/rods/cams - you wont bore in out to 1.6 l - the cylinders will collapse into each other - 1.5 l is really the limit - lagerlout has a picture on his thread of what the walls will look like with this done - he hasnt encountered any difficulty and his car has been a track slag so i think its safe to say its reliably - but as you say its whether its worth it - for me it would be knowing that its the best it can be but others have different priorities - bets of luck with it Dan and to you Jaya - i look forward with great interest t see these builds progressing -
-
sorry i meant 1.5
but to change the pistons for forged ones and the rods i dont think the engine has to be taken out but i could be wrong
if i had it bored it would have to be taken out and totaly striped into a bear block witch will cost alot more than just changing the pistons and the rods
i just cant see the gains being worth it to bore it out
-
to totally satisfy yourself you could get a quote from somewhere - i dont know who would do the work though- lagerlout has been using a touring car firm - but yes i agree with you Dan that it could be quite a lot of extra money and faff for not huge gains - assuming its not silly money, for me it would be worth it knowing that it was as good as it really good be - but yes from any sort of value for money argument its hard to justify - if youre happy with the off boost performance and turbo threshold as it is now then thats fine
-
are TMC supplying the pistons/rods - have the cams you want to be using been tested, is there any info on them - 'turbo' cams in the past have been slightly iffy affairs - i know G -tech sell cams
-
i am sure that lagerlout blow his head gasket
yes the piston rods and cams are the ones that tmc have on thear web site
daron reckons they will help spool the turbo sooner and hold the power longer
i am happy with the off boost power
at motor way speeds i can just put my foot down and not have to change gear and the boost is thear so lag is not a problem
-
Interesting conversation guys. I am just building an engine for my 500 AC that I am converting to be a rally car.
As I am forced to run a 29mm restrictor and cannot port the head, I have to run as high compression as I can and flow as much air as possible, up to say 5000 rpm when the restrictor really begins to limit the air flow and boost.
I have CPS forged pistons with 10.5 compression and am starting with the Garret GT1446, although I have a GT2056 and a GT25 to try (but expect them to compromise the low speed torque too much). The twin intercoolers are being changed for a front mount, and the 500AC injectors are already larger than stock (I believe). Target is 230hp and 350Nm, but I am not sure if the restrictor will allow the airflow ...
Anyway, a lot of sense being spoken by Dan and Griffs. I wanted to know if you are running the Motec M400 and if it can still run the speedo, gauges etc. Also does anyone do uprated head bolts and head gasket ? I will be using race fuel so a lot of boost anf ignition around peak torque !
-
coool
i have no idea about what a m400 thingy is
-
are TMC supplying the pistons/rods - have the cams you want to be using been tested, is there any info on them - 'turbo' cams in the past have been slightly iffy affairs - i know G -tech sell cams
I got G Tech Cams/Piston/ConRod. They said the cams will work with the standard valve and springs but I am not going to risk it.
-
whats wrong with the standard valves and springs
its not like you are going to rev it hard enough to cause valve float
i don't no if any after market valves or springs but i have not had a good look i think it would be a custom job
is it to much to ask to have a 1.4 turbo with the power of a 2.5 turbo
thear is only two ways to make a engine more powerful
1 make the bang on the top of the piston bigger
2 make it rev harder
so thats what the forged pistons and rods are for so the bang at the to of the piston bigger
and the cams do two things it can let the engine rev hight and make the bang bigger at a higher rpm :thumb:
-
Just so you know, if you do go above 250 hp, the first thing to go will be the CV joints. The box will be OK.
To upgrade them you'll need to fit stronger driveshafts, with CV's from the AC car. Also, the driveshafts need to be custom you can't use AC driveshafts as they are designed for the 6 speed box. There is loads of info on this in my thread.
PS my head gasket went only because the fan on my car was not reconnected after it had some work performed on it. An unfortunate accident.
-
so our cv joints are next to go
how will i know when it happens
whear did you get yours and how much
-
For the cv joints keep an eye out for leaking grease from the rubber boots. Also when the steering is turned when going around corners you'll hear a clicking or knocking as the wheels turn.
-
Iv got the drive shaft already uprated from the 190bhp one :) also just got my car back it run just fine on the standard injectors and map sensors and standard map but only hit 205bhp so i need to upgrade them to hit 250 mark and get the remap
-
done it
-
sorry but you have to change some sensors
i told you so
:neener: :neener: :neener: :neener:
sorry i just had to
how about the injectors
-
what sensors did you change?? injectors i still haven't but after speaking to a number of mappers I'm going to upgrade them next week but i still now have to wait a month to get my car mapped!! but at the moment is 205 bhp 301nm
once its done i saved over 2k on the other places offering 250 bhp with the garage i went to :)
Also did you guys have you fog lights removed for the intercooler to fit??
-
Interesting print out to compare sport/normal. You must be :D with the results so far.
-
Yeah i love the sound tho is still the standard exhaust but decate and its pops like crazy :)
-
no my intercooler just clears the fogs
i had to change map sensors
200hp on standard map so what boost is it running now is it 1.2 bar or is it higher deu to so meny bits being changed
is there a set boost you are going to take it to like 1.5 so it will be safe on the pistons and rods and see what you get
or are you going to just up the boost until you get 250 and leave it at that
looking forward to seeing the graph when it is done :thumb: :thumb:
-
im not quite sure on what boost is running as they was suppose to change the gauge when they went to swap them over the engine went in to limb mode so there making a resistor to sort that problem but on the original gauge its boosts to 1.5 and settles around the 1.2 mark but jumps about like crazy so dont really know untill either the gauge gets changed or when the mappers sort it out, i was going stright to 250 bhp with the host but after reading a few of your threads and others I've ordered the pistons and rods cams now so want somethink near 300 which my turbo was built for :)
-
after all that work its coming back to bits poor guy how put it back together
good luck :thumb:
-
After all that work Looks like I've Just blown the Head Gasket or one of the Pistons
MOD: Txt speak removed
-
Ouch!
-
welcome to the "melted factory piston club"
-
Did you ever get to 300bhp??
-
not at this moment I'm still waiting for court case on the car as had major issues with the engine builder doing a terrible job only found this out when i went to a super specialist, so once i get the money off the original guy from the court its another rebuild and then yeah i will get there as the original builder could not fix the faults with the car which he had coursed, and almost coursed it to totally blow up and catch fire as had major leaks!! craziness
-
Bloody hell mate, :-\ the thread has made good reading so far, one of the best I've come across. sorry to hear about your problems. Good luck getting what your owed!! :thumb:

Well mines was not Much better
November last year my gear box went bang
So it has had massive amount of work now it's
6speed box from ac car
Gt2860rs turbo
Forged pistons and rods
Cylinder head porting
Power wise put it this way. The goal is 300ftlb at 7000 rpm
Work it out

Work it out
To help you out its around 390bhp .... So what do you intend to do with all that? Apart from sitting on the spot trying to get some form of traction? ???
-
It's my daily driver
0 to 60 pointless
How fast it is from 60 to 120 is more important to me
Fast over takes.
And to speed at 2500 rpm in top I am doing 70mph
It's max revs will be 7500
It will never pull to the red line 210mph
I don't think I will be taking it past 160 any time soon unless I take a German road trip
-
That is mental, in a good way - major respect to you! However, I don't think you'd get anything like enough traction to make it really that viable? I don't think it would make a remotely usable or enjoyable car. Never mind from standing, you'd struggle to get enough traction in-gear! But then, I could be completely wrong...it could be insanely amazing :)
-
So far. 398hp and 350ftlb at 1.6 bar
-
Dan have you got any videos of this animal of yours?
Would be interesting to see!
-

Certainly would! :whistle:
-
Not yet
I pic it up from mappers at 3.15 straight from work
Started at 7.10 can't be arssed now
Can't wait
-
Not long now! keep us informed wont you?
-
Will do
For the past 2 month I have been driving a mazda3 1.6
My car is going to be mentle
Thay gave me the option to try 1.8 bar witch should have given 420hp
But I want some long term reliability and the aim was 400hp
If its not enough I can try a meth kit and 2 bar
;D
-
With all of these power upgrades what have you done to the handling side of the car i.e. brakes, suspension etc?
You will be needing a new set of tyres every week hahah
-
It spools the same as when it had 255 and the peak power is at the same place
But theirs 100ftlb more.
The car has. Bilstien kit and uprated pads
Plate LSD in a modified m32 6 speed box
(Assets corse drive train)
1st gear. Pointless
2nd gear. On a warm dry day Pointless
3rd. Put you foot down and go baby go
4th. My god it's still going
5th. I think I need new under wear
6th. As yet un tested
It's now raining and took my mam for a spin.
Now removing her finger nails from my leg and the passenger handle
-
You took your Mam for a spin! Ha ha.

Jaya, who created your frankenturbo?

Is now being Created by Bernies Blowers in Essex its actually off the car at the moment while its getting rebuilt and upgraded being even more bored out with a larger 40mm wheel put in, and as for the outside its also getting another make over with this LED grill and vents and rear spoiler http://images-cdn.ecwid.com/images/87523/167860114.jpg http://images-cdn.ecwid.com/images/87523/34406715.jpg http://images-cdn.ecwid.com/images/87523/143727861.jpg

Hey,
where are you sourcing the vents from?
I could only find them for left side of the engine bay, seems that the picture has hem for both sides.
Cheers
-
this is the website, the Kit comes with a hood liner as well which no other kit comes with so its keeps all the electronics and engine from getting wet also shipping is 150 dollars on that item and 300 dollars if order everything which i have just done http://www.acscomposite.com/store/?~~mode=product&~~id=28437929#!/Dual-Extractor-Hood-Port-System-for-Abarth-500-or-500T/p/26818649/category=6919089
-
I like that bumber a lot
But I am not keen on the bonnet vents.
But for me the fun is in looking like a np abarth 500.
-
Yeah i agree the vents are not perfect, but the only other solution is a whole new bonnet with custom vents like like the Romeo Ferraris etc, $$$, or pogea etc, $$$
-
Lift the back of the bonnet by 1 inch so the hole bonnet width is a vent
