Here are my coated pistons ...

The car is almost ready. It should be a good setup. The 3.8 liter with GT3 style intake and exhaust profiled cams, being feed by an upgraded fuel system with larger injectors. It will also utilize Protomotive engineered air intake which are 3.5 inches in diameter per turbo. The Y pipe was design by Protomotive and I think is the largest Y pipe on the market. There are few people I would like to thank for thier help and encouragement; Ben Phillips, Todd Knighton and from Houston Akram and Terry. I am in the last stages of the build. If weather is good and lady luck is with me, I will shoot you some video in a couple of weeks as we road test her.
Merry Christmas

Secondly for me to go to the next level which would only gain me 100 hp costs like $20,000.00 so forget it. My car spools very quickly and can whip anything short of a 1200 hp Viper or Supra, be faster than anything but straight out race cars at the track and still get 23 mpg on the highway out of the boost.

Thirdly I am going to regear the car and then it will be even better!
Buddy , couple quick questions. I assume you are replacing all your gears right? Otherwise, I cannot understand why you are driving that car with the debris from the blown out 3rd gear crunching between the other 5 remaining gears and bearings. As for your recommendation for a boost controller, I assume you have the GT700 flash that came with the kit. That is a fixed boost file. Since you are raising the boost with the EBC on a fixed boost file, how are you getting additional fuel to compensate for a lean condition? Kevin

Obviously there are 700+ h setups with people who get lucky, and no issues. I would say for a fast car and dead stock reliability and drivability, my setup, you've seen it run and its bulletproof and quick as hell..

Other then that? Your setup now... 750, 800 on up start using bigger turbo's I believe, more lag and more traction issues, that's probably the minor hassles and headaches from what ive read, although you never know.
