http://jakesperformance.com/Transmissions.html is where I found the 4L80E. I dont think it was used in the SV6 but im not sure. My plan, well I plan around 1000hp or more at the rears also Stee3. Completely rebuilt driveline, diff etc, monobloc 4 piston fron and rear brakes, Built motor, GTX4508r turbo is what I wish to use, Process west s3 intercooler, APS exhaust, there are lot of other parts I will need also to get there I understand that, this is just a general overview. Budget will be over $30000 easy im guessing, im not a mechanic so I cant really do any of the work myself. I'm aiming towards Autotech to do the tuning and motor work. By the end of the project The car will most likely just be used for the strip, but I would try and get it streetable at that power level if possible. My car is 07 MKII BF turbo.
