I am one of very happy customer with on3 2v kit. I am also one of very few who bought this kit when it was first out, for my budget it's a great kit and works very well. Even with stock 2v heads I made 687rwhp and 677 torque but had valve springs problem, now that I have high load valve springs I'm sure to be over 700rwhp.
This kit kicks ass for what it cost, always wanted a turbo kit but coundn't spend 6k for the kit . Thanks to on3 now I am enjoying boost , this kit work great with 400rwhp and even at 700rwhp it is doing a great job.
