Hey i just wanted to know what size turbo guys are running, I currently have a 50 ar turbine 63ar compressor. but im thinking about getting two other turbo's (one or the other not both lol), one is a turbo a local shop has on display, its a garret gt35r they said, and the other is listed in the jbody classifieds right now, its a garret 60 trim, the reason why is because i just dont think my car is making enough hp per lb of boost, I heard a story that i refuse to believe today, a guy that is a freind of mine has a civic si 08, he is running 10lbs, and he went from 197 bhp to 420 whp thats almost 500whp, that is a 300bhp gain, 30hp per lb of boost????? wtf is this even realistic, on my first tune i got about 230 whp on 9psi, this was a very crappy tune that was done at a dyno shop and since has been corrected (by brandon aka cavfan1 and me), but that was about 10whp per lb of boost which i thought was around average.


if it can't win a race it better win a show

i have a garrett 57 trim 60 AR on my ecotec sunfire

gt35r /thread

If you plan on a GT35r, you better start building a stronger motor

Do NOT put a gt35r on a stock motor. Youll blow it up before even reaching half of the turbo's potential. Choose a turbo for what power goal your looking for and what you want out of it. Do some research.

Im currently running a t3 super 60, .60/ .63 which is a good turbo for making 220-250whp on a 2.4. After my motor is built Im planning on going with a holset hx35 with a divided housing. Holset/bullseye turbos can be very similar to many of the garrett gt turbos, only difference being journal bearing instead of ball bearing, but can be had for a quarter of the price.

ok I have a spare motor that im planning on building in my garage, but im also looking for a 92-92 short block since that block would be better, i have a 95 2.3, ok the right question i should ask is what do u guys think is a good size turbo to put down about 250whp, im sure the turbo i have now can do it, but i would rather a turbo that can do it with less psi, i had it all the way up to 17psi (accidently, the wastegate was not working, i would never do that on a stock motor purposely) luckily i did not blow the motor. but can anyone answer my original question about my friends civic si making 420 whp on 10 psi, is that even realistic for a car that had about 160 whp stock, gaining 260 whp on 10 lbs,

I'd expect him MAYBE to have 260 total... maybe he has a lot of stickers?

.63-1/.70 is what I'm running on the Sunfire right now

Precision sc61 is what i'm running... .70 compressor .82 turbine. Basically equivalent to a gt35r minus the ball bearing
