Hello,
I'm looking for help choosing best combination that will give me best possible responce with about 350rwhp. I have to say that this is for Renesis engine in a custom chassis. So I'm looking for turbo that will work good from low to 9000rpm. Car is not intended for drag but street and road racing - so gradual and early tq/hp build up is priority... Even if less than 350hp will be the result.

It seems that GT35R is becoming very fashionable... Is it one and only best solution? Can I ask some owners to share their experience about their cars - RPM vs boost build up, etc.


Thank You
Ted

 

I think the best option for your desires would be a-spec's 35r kit with the t3 exhaust side. It will also be capable of well over 400 hp if you desire.

 

Edit- just noticed it was for a renesis motor. Pm Sean on his name Zero R. He should be able to get you the turbo.

 

T3 anything isn't going to have a gradual torque curve which you want on a road race car.

 

I don't think 35R will take you to your 9k redline (especially not T3). Look in to 500R and T04Z. There are Garrett T04Z clones for less but not a kit. You can ask A-Spec if their T04R kit will work. ...if they have one for the RX8.

Renesis climbs RPM's very quickly and smoothly. A BB turbo is an excellent match. My 500R does not have a kick to it. It is very smooth when it comes online and boost is almost instant.
