GT2876R (GT2540) b18c, is this to big?? (Need to know asap)

[Codeman]

Hey guys,

Looking at buying a genuine Garrett GT2876R. (GT2540)

Model number is 705330-1

From what i have found on the net the specs for this turbo are..

Comp side
Inducer - 52.7
Exducer - 76.0
Trim - 48
A/R - .70


Turbine
Inducer - 53.8
Trim - 76
A/R - 0.64


What i want to know is if this is to big for a low boost b18c setup,
Got hayce's manifold on the way (t28 flange)
B16b head, So all the ctr gear in the head,
2.5 " exhaust,
All the bits n pieces.

Will only be running 8psi tho,

I really didnt want something that spooled late, thats why i started looking at the GT28 series in the 1st place, but the turbo is mint, Great price, fits the manifold, and is ball-bearing.

Throw all your opinions n what ya think itl spool at and how laggy ect ect

Also what turbo would this be compared to?
I know people have run t3/to4e turbos n have made good power, but im sure they didn't see it till after 4k??

I want around 3.5k max! its only for the street so a good responsive turbo is what im after, Not worried if i get 200wkw, id be happy with 180wkw as long as its on boost reasonibly quickly, just for around town n open road everyday driving.

CHEERS, Lemme know!

hmm i dont see any "GARRETT" on the compressor housing

I'd run it.

Hard to be sure, Hondas spool turbos ok but the GT2876Rs run quite a big compressor - even if its not well utilised because of the tiny turbine side. They're famously badly matched, and really the compressor is something that should be on a GT30 so the spool won't be as good as you'd expect from a "GT28".

Its definitely quite overkill for a 180kw low boost setup, and I wouldn't count on it being fully on song by 3500rpm - but I reckon you will have some boost/be pulling harder than an NA equivalent by those revs. It's basically like having a ball bearing T3/T4 - will spool better but not extraordinarily. I reckon it'd be ok on a B18C though, with potential for some fun power if you get a stronger motor.

maybe not if youve already got the exhaust manifold and other stuff.

Not after the cheaper parts mate, no offense.

Yeah getting a masterpower gt28 through evltek, non BB but comes with warrenty and will still spool up quick enough anyway..

Cheers.

masterpower and XS power are the same things arent that?

cheaper knockoffs of the real thing, (not saying they bad or anything)

XSPower are pretty crap by reputation, Masterpower aren't the same company and there are quite a few people running their turbos with no problems (including top drifters in NZ), Turbonetics are another known Garrett knockoff.....

[DC2r]

xspower= made in china and taiwan, masterpower= made in brazil of all places i read somewhere?

[Hayce]

Yep Brazil AFAIK...

bit of a contradiction there, not saying they are bad, but they are the cheaper parts...

[Dezigns]

Masterpowers dont like oil pressure... ive flogged out the seals in 3 of them.
make sure you run a restrictor.

Yeah sorry i should have worded it better, that hits it on the head with what i meant.

Will do the job.

Being that its non Ballbearing,
Is there a big differance between spool times on bb or not?
Thought it may save wheelspin, will be happy if its singing by 3k.

[TuLaLiT]

ball bearing normally only spools up about 15% faster but cost a lot more to buy and being a water cooled you need to buy AN fittings and braided hose

Aslong as your buying quality they last much longer without a rebuild. IF you get them setup right.

Singing by 3k? it will begin to build boost around there.

lol sorry i forgot to turn the smartass function off when i typed that i actually thought you actually thought they were the same turbo, hence my repsonse, not having a dig, crack is whack, calm down

[FLYRYD]

ive got the GT2876r on my ITR, gets 8psi at about 4000rpm and 16psi at 4300rpm.

[EVLTEK FBI AKL]

you are running lower comp though right allen? so on a standard comp 1800 you would expect around 500-1000 rpm lower?

And how hard does it go? on 8psi of corse.

Yes im on standard comp.

Guess its to late now since turbo is allready on the way, other wise i would have got the gt2876r just from your statement


Bugger.

Compression makes a bit of a difference to the way it drives etc, but not 500-1000rpm difference by any stretch of the imagination....

How is boost @ 3k going to stop wheel spin?

if he has a really really really heavy flywheel

trust me it doesnt stop the wheelspin problem..

Maybe letting me pick up a little more speed before it boots me in the ass?

I dont know, maybe talking out my ass, havnt owned a vtec turbo before.

Got turbo today, very nice.
Still waiting on manifold.

will let ya know how it goes.
