get the stage 2. and dont get a spring that large. get a smaller spring and use a boost controller to take it up from there. 10.5 or 11.6psi will make too much for the minimum power IMHO, especially if you ever let anyone else drive your car.

personally i run a 6psi spring so with boost controller off i make 450rwhp and thats a nice conservative DD power level, and pretty dang low risk in terms of engine failure, even the older DE motors could hold 450 all day. its effortless to drive and quick enough for most circumstances. also, i am much more inclined to let a friend drive the car like that because it really only blows the tires off in 1st (305 RE11's with 1.4 degree neg camber). at 8psi the car rips thru the tires in 2nd, and thats too much wheel spin for a less experienced driver. the smaller your turbos the faster they will come on and the more wheel spin you will get... thats why i say go stage 2... because the extra torque from the stage 1 is going to just be wasted to tire spin anyway, and once your in the higher gears of a race you would never be at those lower RPMs anyway. im using the greddy 20g kit which are pretty large turbos, i would expect the GTM stage 1 and 2 kits to both make more low end torque and be more responsive, which is fun in its own right, but for the type of HP these cars make with boost, i personally believe that turbos can come on TOO early making the car a lot more of a handful then it needs to be, without making it any faster in a "race" situation. so i say the larger the turbos you get the better (within reason), and remember bigger turbos make more power at the same boost pressure, so if anything you would want smaller springs with a higher stage, rather than larger springs.

get a clutch and flywheel. your turbo kit will come with a fuel system. upgrade your oil cooler core if your oil temps are constantly over 220 with your driving style after the turbos. to even have one at all is better than nothing so i wouldnt exactly worry about it yet unless its a problem.

all just my own opinions of course.
