Gt2876r

[Limbo]

Just wondering if anyone has a GT2876R with an .64 rear on their b16?
Just wondering if someone can give me an idea of when it starts to build boost and when it actually hits full boost (say 10PSI or so)?

better to just do a gt30r with the .64 rear housing, the intake and exhaust turbines are too out of proportion, the max i'd go is a gt2871r, the 76 will be more laggy. either look at a gt30r .64 otherwise look into a gt28rs by atpturbo.com, slightly larger than a normal gt28rs due to a custom .86 t3 housing i believe good for around 350hp without power dropping off radically.

i believe the one i have is a GT2540, the HKS version of the GT2876
It has the smaller front (SR20 a/r .60) rather than the .70.
looking at the specs, the rear & rear wheel seems the same to a 28RS, and with a smaller front, i think the only difference is the compressor wheel is larger.

Would it still be as laggy?

Sounds a lot like mine Hao

440HP Garrett/APS SR40, GT25 Based Turbo
.86 a/r Exhaust, Flanges Supplied (hoping the log manifold will help with the lag)
.60 a/r Inlett, 2" Discharge, 2 1/2" Inlett
GT 25 Flanges

i dun think the manifold will make that much difference. I think its the turbo characterists, dunno i'm gonna ask Adrian if he knows

Have you bought the turbo yet? If not, Gt30 would be a nice choice.

Yeah he brought it as I have lol

Mine only cost $900 brand new so I can't justify spending $2000

I can live with a bit of lag to start with and change down the track if its not to my liking

I'm used to lag with my old non BB turbo anyway hahah

[Limbo]

yeah its being delivered tomorrow or Weds.
We'll see what happens then.

after some research found out that the hot side is identical to a gt2871, and spooling is basically identical.
Only diff is that the front side is larger. Hopefully with the smaller front housing it will not be that laggy

[Lukezen27]

So can someone explain to me how this works?

.60 in for faster spooling then .86 rear with curse lag..

Still learning this stuff

thanks that was a good read.
Fingers crossed it works that way when i put it on the car
