either. Cause the Supra pro's are running high 6's and the pro Z's haven't made it in the 6's yet :(. I also think if one stops to go over the 3 major Supra shops and look at the selection of parts and fabbed products, one will see the clear advantage here. Supra's have all kinds of crap made for their Street cars to race just bad ass times. From little 2 step rev limiters that raise the boost in manual to 6psi just sitting there on the line, to locking rear diff gear so both rear wheels receive the same amount of power, thus helping keep the car straight with it's 700/900rwhp. So many turbo kits one can't count them all.
