the ssautocrome manifolds are prone to cracking. the turbo's are prone to blowings seals quickly. the wastegates are fairly good(better than a deltagate). the front mount I.C. seems to be good quality(I've seen 4 of them). with that kit you would still need intercooler piping+150(at least) soo its really not that cheap. your better off spending $1000 on a nice used kit.
