Motor: (RB25)Engine Internals: (built bottom, tomei pon cams)Fuel System: (550cc, bosch044 pump, nismo regulator, crappy california 91 octane)turbonetics t72 / ebay/ tial 38mm wastegate:Management: (aem ems)Dyno Results: 411WHP & 302ft lbs Tq 16psi

upping the injectors to 750cc also going with a holset turbo, should be making 450-500whp and hitting full boost around 4000rpm. not bad for a daily driven car.

Dunno I can see puffs of smoke from light misfire in the top end still. I think it could make much more but I don't know how much.

<3 Q16 You can see torque kept going up with each timing bump. I could have kept going but I ran out of time. I'm using BKR8EIX @ .22"

I'm in central FL. No idea about tuning shops but I would just find one that's familiar with power fc's. It's really simple to use.

I sold the first one, with the top mount setup, and the owner put a gt35R on it, and was made 465whp with a 75 shot, and took it to the strip a few times then it started knocking, n now its a RB24 shooting for 500wheel.
