Title: Upgrading the Abarth with a GT1446 turbo.
Post by: Hampe on March 17, 2013, 06:39:41 pm
Hey peeps!
Registered on this forum because it seems like some of you guys knows what you're talking about. I myself is Swedish(hope this is allowed  ;)).
Now when the spring is approaching I will order a GT1446 Turbo upgrade package from TMC motorsports(the one for 1800gbp).
My car is a 2010 EsseEsse, and what I've read so far is that the brakes needs to upgraded for such an increase in power. But I dont understand why? It's not that I will push the 125mph and such, but I will just enjoy the acceleration alot.

If I turn it in to a local tuning company to do the upgrade the work will cost loads, since it seems like you have to disassemble the whole front of the car. For a guy who likes to get his hands dirty, can I do the work myself?

Thanks in advance for the answers. Best regards Hampus in Sweden. I will keep you guys posted with the project.

Oh really? Sounds nice! Do you have a thread somewhere where I can read about it? Or do you mind telling more about it?

Im kinda looking for a turbo upgrade that isnt that "custom", where you cant spot the difference if there is an turbo upgrade or not. I think the GT1446 will suffice just fine?

But Jaya, did you have to remove the whole front of the car to make the switch?
Title: Re: Upgrading the Abarth with a GT1446 turbo.
Post by: jaya on March 17, 2013, 07:17:03 pm
the way mines been fitted you wouldn't tell it was "custom" the heat shield hides the turbo so you wouldnt know if your still looking for standard look i will up load some pics this week, its just an option as its half the price for lot more power,
 As for fitting i know the bumper was off thats it as i did not fit it, if that helps

Bumper will have to be removed with any turbo work, pretty easy to do, just a matter of unscrewing it  :thumb:

Post by: GTMartin on March 17, 2013, 07:21:04 pm
From what I have seen, the bumper is taken off to give more room and better accessibility of all the nuts and bolts. Also it will not get damaged if it out of the way.

The first person to get this conversion didn't think they required the brake conversion, well that's until they went grass-tracking...

work out what power you're wanting and then you'll have a much better idea of what constitutes a 'good' turbo - some people, and there are some, will like the standard IHI turbo because it gives snappy, lively performance lowdown, which they can make use of - others like a much bigger turbo that comes on from 3 - 4k and pulls hard to the redline, others like something in the middle - the trick for a road turbo is working out the power you want and then finding a turbo that is just big enough to achieve it, so you get the power you want and the best possible response - a 1446 will work well for 220ish and below

Post by: Hampe on March 23, 2013, 01:52:28 pm
I would like to have about 200bhp, so I guess the 1446 is the right choice. Does it have good torque on low revs?
Title: Re: Upgrading the Abarth with a GT1446 turbo.
Post by: Griffs998 on March 23, 2013, 02:13:50 pm
perfect for 200, right in its sweetspot i would imagine - it'll have a decent amount of torque sub 3k rpm - put it this way you wont be able to get 200hp with any more low down torque - the standard IHI unit is too small for 200, and any turbo bigger than the 1446 will really wipe out sub 3k performance making it feel at low revs unboosted
Title: Re: Upgrading the Abarth with a GT1446 turbo.
Post by: Hampe on March 23, 2013, 04:07:09 pm
I'm thinking I will put the new turbo there myself. How hard could it be, right?
Do you think you guys would be interested in me making a how-to guide along the way?

I have the first tmc 200+ Abarth.
With the 1446 suplied by Abarth
Best result was 227.
Have a look at you tube link.
If you don't want brakes that's fine.
But they do help
Any questions fire away.

What exactly are you ordering? .... Put it another way ....what are you fitting- exchanging? Is it just the turbo or are you fitting anything else? Sport CAT, oversize centre pipe, induction, intercooler etc?

 ???
Title: Re: Upgrading the Abarth with a GT1446 turbo.
Post by: Hampe on March 25, 2013, 09:00:25 am
Turbo, gasket, manifold, top heat shield, top water feed, oil feed pipe, compressor outlet air hose, 200 cell sport cat is included in the kit.

Will the cat affect my emissions, will it pass through the annual inspection of the car?

I'm really interested to hear how you get on with this mate as I'm really interested in it myself!

I have gone as far as I can with Abarth goodies as I can with my car.. I've got sabelts, brembos, Monza konis esseesse and this kit is the last step to make it pretty much a manual 695!


Is the turbo manifold etc Abarth parts? Ie the same parts that are fitted to the 695's??
Title: Re: Upgrading the Abarth with a GT1446 turbo.
Post by: Hampe on March 25, 2013, 10:32:48 am
Good question, I guess it is. Ill let you know when I get the kit delivered!
Title: Re: Upgrading the Abarth with a GT1446 turbo.
Post by: mightydquinn on March 25, 2013, 12:09:01 pm
The 1446 is available at your dealer.
I believe it to be around £2000
But
If its the hybrid one then that's the 230 kit dans got 255 on dyno
Mine was suplied by my dealer and fitted by tmc.
He has done a few.
And yes hi flow cat should still pass emissions
As mine was moted in November. And Mir is an Abarth 200cell cat.

I was under the (possibly misguided) impression that new injectors were needed to upgrade to the same spec as a 695?

Or is the intention to bolt on the turbo and do the best with the current ones?

Does anyone know if tributo injectors are same as ss?? I'm curios about this gt1446 conversion, I'm almost there for tributo specced ss!! Just turbo and accessories to go!

Post by: Nadeem on March 26, 2013, 08:01:27 am
Take a look at the AGP SS kit contents, that's essentially what you need.  Iirc you should need the injectors, but I'm sure there'll be a sticky or topic about this to confirm.

The standard Injectors are good for over 200bhp mine are standard and it runs fine altho i have just ordered the Big red Injectors

Hi 124 what ECU are you running? Injectors? Do you need new intake for the airbox? Did the turbo come with everything for direct replacement?
Title: Re: Upgrading the Abarth with a GT1446 turbo.
Post by: 124grandeabarth on April 01, 2013, 09:24:11 am
Complete AGP SS kit #220 ecu remap by Scantune in Denmark start with tributo settings, and then we went for max 200 bhp just like what Abarth does with asseto corse race car.
Title: Re: Upgrading the Abarth with a GT1446 turbo.
Post by: 124grandeabarth on April 01, 2013, 09:45:51 am
Yes I using tributo intake too the original airbox.
All sensor and injectors has been change.

Post by: Hampe on April 22, 2013, 08:36:06 pm
Was pretty much just about to order the kit for 1799 GBP from TMC.

But after some e-mailing between me and TMC, they didnt recommend just getting the turbo with manifold and cat, but getting the kit 3495 GBP with uprated injectors and such.

Thats like double the price, so for me as for now, No Go...

I have the 500 AC race car converted for the road. I just ran it on the dyno - 205 hp at 5300 and 292Nm with very flat torque curve from 3000 to 5000.
Spec is GT1446 with 300cc injectors, updated boost sensor, marelli exhaust with cat and cone filter. I believe peak boost is 1.6 bar at 3000 but it reduces to 1.1 bar by 6000. (That is the standard AC map).
Very easy to drive on the road, but feels a bit flat over 5000.

Just about to remap for more boost at the top end, so will keep you posted.
Title: Re: Upgrading the Abarth with a GT1446 turbo.
Post by: londonrichie on May 07, 2013, 10:31:15 pm
Definitely more to give with the turbo. I have 290nm torque on the standard SS turbo...

Mightydquinn has remapped his A500 to 235bhp/325nm running a very similar same set up on the GT1446. Good luck :thumb:

Post by: dan vbv on May 08, 2013, 01:23:46 pm
when i did mine

i was undecided weather to go for the gt1446 kit or the 230kit   

thay are very close in price i am glad i went for the 230 kit

as it is going to be cheaper for me in the long run as i am looking at 300+hp and 300ftlb

my car is only running 1.55 bar of boost the turbo can run 1.8 so i just need to upgrade the inside of the engine and get a custom map to get more power

you could get the gt1446 and fit it get a custom map but you want get the power it is capable of   but once its on the car and running you could to the other bits when you can afford them to take the power up

Post by: Han5y on October 04, 2014, 04:37:53 pm
Its a little bump, but its much of the same as the threadstarters.

Have the 1800£ kit been removed from TMC? I cant found it..

Is it removed becouse he recomends the more expensive kits..?
Title: Re: Upgrading the Abarth with a GT1446 turbo.
Post by: Sphilli2004 on October 04, 2014, 07:19:24 pm
I think scara73 is the way to go over TMC now. The kit is much cheaper and like the TMC kit you get everything, unlike the TMC kit you can pick and choose what bits you want. They also do a number of turbos where you use an interflange so you can keep the stock manifold and get 225+ bhp

Perhaps people can correct me if I am wrong but I believe TMC get a lot of bits from Scara73 and then add their premium, I think TMC are quite expensive on some bits.

Why not take a GT1752S from a Saab Turbo, thats a step up turbo from the GT1446. I have the GT1446 on my US built Abarth
Title: Re: Upgrading the Abarth with a GT1446 turbo.
Post by: mightydquinn on October 31, 2014, 02:49:16 pm
The advantage with TMC is
He tries all the different options

I have dealt with him
From Abarth day 1
The service and back up
Product knowledge are first class
I don't think he is expensive.


I have taken my 1446 off.
And going hybrid target a nice useable 270 Bhp
I like the 1446 as it is designed for that engine and bolts straight on and works exceptionally well to produce 235.
New car new project.

Nope. It can be modified i believe.

But easiest option would be just to buy the manifold off the Punto for that turbo.

Post by: Danny-hall on September 23, 2015, 05:45:45 pm
Mightydquin, you said your hoping to go upto 270bhp are you doing that on standard internals or is your engine forged? Iv read that the engine only with stand 260bhp and around 320nm, be good to see how you go with 270bhp cos im running a TD04 turbo on my a500 capable off around 280bhp so i could turn boost up if your running 270bhp, im at 230/240 now
