10k? on itr cams? no valve train?
not only will you stop making power at about 8300, i wouldn't trust the vlave springs over 8500ish.
the ITR tranny is much more durable than the LS. don't even consider running the LS tranny. you will hate your self. plus, the ITR has an LSD in it too- which will help.
i say, jsut get the ITR head. the ctr is more expensive, and frankly, its practically the same damn thing when all is said and done.
the ITR doesn't have headers. it has 1 singular header. moreover, i would suggest going with a Kamikazie header for a JRSC application. it has larger runners and can be had with a 2 1/2 collector as well. 3" exhaust will help you out too.
don't run a p72. you don't have IAB's so why buy an expensive ass ecu that your not going to use?
hondata on a p28. you will make a butt load more power, and be safer.
i think you need to re-think your build a little more... in terms of the fact that you are supercharging.
