that alone sounds sweet 5sge 1 of a kind im sure it will handle boost ok just dont try and make it rev 2.4l with a turbo should make good power at lower rpm anyway if you tune it and have a rev limit setup for no more then 6000rpm and 10psi boost you should be ok i reacon as long as you have rebuilt the bottom end and if you do some mods to the bottom end like rods, pistons, mains & bigend bolts etc i think 1.5 bar (20+psi) should be achievable but i still wouldnt rev it over 6000rpm Out of curiousity, you're not joking right. From what I have read, a turbo'ed stock 5sfe should pull only slightly more than what a stock v6 does if you want reliability. Hence why a lot of people in the states recommend dropping a v6 in it and then working on from there.
