Hi Stao
would like to thank you for your excellent product and customer service mate. Little bit of background info: I bought a Hypergear ATR28G3 off Stao as an upgrade on my R33 RB25DET S1. Only looking to achieve approximately 250-270rwkw. The turbo is on the car now and on 14psi with power fc, 740cc Nismo injectors, splitfire coilpacks, greddy fmic, AM Performance exhaust, Bosch 040 fuel pump its making 246.6rwkw with a leaking exhaust. Ran out of time as i needed the car hence why the car was tuned with a leaking exhaust.
According to the tuner there is potential to get around 260-270rwkw with this turbo once the leak in the exhaust is fixed and the boost is raised. The turbo was a straight bolt on.
Highly recommended!
Thanks
