single turbo and 3.5 heads - 5/11/2007 10:20:08 PM    csladek11   Posts: 11 Joined: 8/25/2006 Status: offline i have a 92 stealth es dohc. Iwas woundering if I could put 3.5L heads from a montero on to my car. I would rebuild them and im pretty sure they would bolt up or would they? Also I was thinking of custom fitting a single turbo to my y pipe instead of my manifolds to get equal flow but I was wondering if it would be to hard to do or would tear up my motor. I won't use much boost only like 10 to 15 pounds. I dont want to spend much money on it all thats why im not doing a whole tt conversion but i just want some extra power. Any info on any of this?

I'm not sure how much tt convertion costs but one turbo is an option(just not common).I wouldn't think that 3.5L heads from montero would fit. Personaly i think 10-15 psi is a lot of boost, when i was thinking to do mine i was going to set it at 5 psi(my stealth have a lot of miles) < Message edited by yevgenievich -- 5/11/2007 11:35:47 PM > _____________________________ (in reply to csladek11) Post #: 3

I did seen double supercharged gto tho, those superchargers were sticking up higher than the car it self. But eight turbos.... I wold think that after you get twin turbos the effectivness of next ones goes down to almost nothing. _____________________________ (in reply to thestealth) Post #: 9

To think having 8 turbos set at 5 psi each would give 40 psi total, so the engine would just melt of exsesive boost. somebody have to explain to me how 8 turbos would work, lol. _____________________________ (in reply to EvilZombieZ) Post #: 11

Corvette with twin turbo setup makes almost 1000hp so having 8 turbos making 700hp is a waist of turbos and space under the hood. _____________________________ (in reply to EvilZombieZ) Post #: 13
