Garrett 3076 power??

[Burglervr6]

So I just picked up a Peakboost topmount manifold and a Garrett GT3076r with a .86AR i think... I have a built Sr had a 35r with a crappy topmount mani b4 and on 13psi made 437whp. I am curious to see or know what numbers people have made with this turbo I am looking to run 20-25psi if possible. Thanks for the responses in advance!

nice .

power can be made easy but not 13psi easy. doesnt should right to me.
we have had several SR's on gt30's making over 450 and all well above 20psi but 437 on 13psi is hard to believe.

Rule of thumb, add a 0 to the Airflow (#/min) and that is your max hp potential

This is my favorite turbo for the SR...

PERIOD.

Especially if you end up boring or stroking it.

It is nearly identical to the HKS GT3037S

If you have seen time attack cars in Japan with SRs then you know this turbo and the TO4Z are slammed on lots and lots of SR motors over there...and it's not for no good reason.

My last project car (sold about a year ago) did 425 WHP on 19 PSI of boost on 91 octane piss poor cali gas and a Haltech EMS, with stock pistons and rods... no doubt.

Just make sure not to skimp on your EMS or tuning. Research your tuner and get to know your tuner before bringing it for tuning. If you can teach yourself just be careful and gentle and get a safe map to start from if you can.

The GT3076 is a great choice for a 450+ hp SR20 setup.
I am running a Gt3071 on my Built setup, made 459whp on 18 psi 93 pump gas.
Car is running Peak Boost manifold, and aftermarket intake manifold aswell.

In most cases a GT35R is too big for a SR that is not meant to be a drag car.
The GT30 Series turbos provide a good response and power output.

But yes everyone is right, a proper tuning system and tuner are vital to the success and survival of your engine.

Let me know if I can help with anything.
Thanks,
