Gt2876r

[Limbo]

finally found some positive info about this turbo
from http://www.pumaspeed.co.uk/showdetails.php?id=217


Power 300-380 bhp

Fitting Charge: £ 287.5Open the door to big Power 300-370 bhp

DIY fit
Fully reliable and tested
actuator set to 20 PSI
All Pumaspeed Turbos Now come with a FREE FORGE actuator upgrade worth over 100 pounds

Wow
Power and torque are on the up 310-350bhp !!! fully reliable and tested. This now industry standard GT2876RS Turbo was the first to be used on the Focus RS and still holds the official record time at bruntingthrpe proving ground
A perfectly balance turbo that will fullfill the power hungry.
Tests on our own development car have seen power of 325-380 bhp dependant on engine spec
GT28 down pipe will be required and a turbo fitting kit
See demo car in the gallery section
The 54mm turbine wheel and 0.64 A/R turbine housing enable ultimate responce combined with powerful air flow from the 44 lb/min compressor wheel.

Focus RS Turbo sizing guide.
There are very complex naming standards in the world of turbo building, so we have simplyfied the naming process to assist in the understanding of the complex world of turbo design and performance,

The GT25 is a std turbo as fitted to the FOCUS RS.
The GT26 is a better version of the std turbo - not popular as a power upgrade - alows for higher boost and minimal flow added.
The GT26Plus Hybrid (we call it a gt26Plus as it still uses the original restrictive FORD exhaust housing although we heavily modify it) - it is for those who do not want to swap down pipes oil feed lines but do want as much as possible from the etc
- can flow 330+bhp and 28 PSI (not that you willl ever run 2 bar !)
- positive boost starts as early as 2100 (mapping dependant)
- is fully gt28 cored (roller bearing)
- uses a heavily modified machined & ported exhaust turbine housing, 71mm high flow compressor wheel from the gt2871 we do,
- complete with with a H Duty billet Forge actuator worth in excess of �100
- Produces an healthy Increase in torque and horsepower over the gt25 std FRS turbo

The GT27 low lag aka. the GT2871RS a true GT28 in all sense of the word.
- requires the gt28 downpipe and fitting kit and is best fitted with a high flow manifold.
- Fully roller bearing cored
- has proved over 350 bhp in this application 390 in others !!
- positive boost starts 2450 (mapping dependant)

The GT28 aka. GT2876RS a true gt28 in all sense of the word.
- requires the Milltek sport GT28 downpipe and fitting kit and is best fitted with a high flow manifold.
- Fully roller bearing
- has proved over 350 bhp in this application 390 in others !!
- positive boost starts 2650 (mapping dependant)
- full boost near 3300
The GT29 aka. GT3071RS large power 420 is well within it capability, should be used with very well moddified cylinder heads.
- requires the gt28 downpipe and fitting kit and is best fitted with a high flow manifold.
- Fully roller bearing
- has proved over 395bhp in this application 440in others !!
- positive boost starts 2850 (mapping dependant)
- full boost near 3500

The GT30 - too big for road use must be used with external wastegate and is only for cery bespoke engine conversions 500-550 bhp.

[[ricer]]

woah what u doing hao?

not happy with your current set up?

[Limbo]

LOL is that cow shit or horse shit?

Ricer - yeah got the turbo bug

Toda - didn't you tell me abit of lag is good?


Waiting for it all to be put together now!

THen tune
Then LSD

and then off to eastern creek again

[[ricer]]

turbo bug has bitten u hard lol

good luck with all of it bro

[mooshie]

what about this- http://www.turbobygarrett.com/turbob..._700382_20.htm

So would this be a good turbo? on a standard B18C/B16 and about 8PSI.

So would this be a good turbo? on a standard B18C/B16 and about 8PSI.

Yes it would but I lot of people say got GT30 with .68 rear instead of the 0.86 in that link..

I'd say on that size turbo they'd be right but not all believe that

I've got a GT2871 with a 0.86 rear to make up for the smallish turbo size as is my understanding

[Limbo]

yeah apparently the GT3071r is the choice of a hi-power turbo.

We've got T28s cos our manifolds are T28, that's what happens when you start small and build your way up

see you there.
getting tuned on sat.
=)

[Limbo]

lol i don't think i'll be there, still waiting for it to be put together!


BTW.... what do u guys think about my injectors, i'm only running 440cc, do u think they are large enough?

some more info i found....

The GT2876R (AKA GT2540R) in my opinion suffers from to much compressor for the turbine.

A bit of back ground on the 48 trim T04S compressor used in the GT2876R.
The 48 trim TO4S compressor is cut from the same compressor casting as the 7 bladed GT3076R, HKS TO4S and the tried and proven TO4 60-1.
It’s all the same compressor casting but in different trims.
It is also a very good compressor when matched to the right turbine.

The TO4S compressor wheel has received a pretty bad name over the years because Garrett seem to keep under driving them like with the GT2876R making a lagy turbo for its size. With the GT3076R’s the 56 trim 6 bladed GT30 version flows about the same as a 50 or 52 trim 7 bladed T04S version so when they put a 56 trim TO4S compressor on a GT30 turbine the turbo becomes quite a bit lagier.
The TO4S compressor wheel really needs a bigger turbine trim for trim to work properly.

The GT2871R compressor is smaller and flows less than the GT2876R so it is a better combination for a SR20. Especially in the smaller trims.

smallest turbo id go is a gt28rs atpturbo.com modified gt28rs with their t3 .82 rear housing this will be good for 300hp easy, pushing on 350hp maybe, perfect for a stock motor.

otherwise the gt3076r in .82 rear 300-350hp for a stock motor planning on getting rods and pistons.

then gt35r in .82 for 450hp + on a built motor going to insane levels is the gt40 or 42r or something from borg warner.

the top turbo's are the one's to look at basically, remember its a fwd, lag is not all that bad, too much torque = no traction and fry the tyres.
