So i have an 89 7mgte car that is just a summer daily..Looking to make 450-500hp but i would the fastest spooling possible. i was thinking about an hx35w t3 or a hy35w or a hx35w inside a dsm .55ar housing. i ran a 3071R in a .48ar dsm housing on a 7mgte before n it was insane. i made just over 465hp made boost just over idle n had a full 22psi by 2200rpm..i have been looking all over the net and im getting mixed answers on what the ar. numbers really are on the holset turbos since they measure them in cm2..i know the hy35w is basically the same as the hx35w only the exhaust housing is is a smaller ar. but would that be smaller then the dsm housing???? please keep in mind that this is not my real project car..my baby is a 87 drift car with a built 2jz so this is just something to play with on the side without putting tons of money into it...i know some of you guys have been ruunning these turbos n was looking for answers on the ar. #s on these n hp #s n rpms on spooling..thanks for any help you guys can give..
