Okay well i went to my machine shop that did my bottom end he said i have .20 over and stock replacement pistons and a polished crank that is all he did for the bottom end... I asked him what does he think about puting a turbo on my car but only running about 5-6 PSI he said it should be fine just dont boost it up anymore... What do you guys think. I got 3483 miles on my new motor I just dont want to see it blow upp.. Will it last or what.. and if u guys think it will be alrite how much hp gain should I aspect only running 5-6 psi?
or would supercharger be better.. please let me know i want something and how hard will it be on my motor?
Turbo would be fine on that boost level... im running 10-11psi on a bone stock bottom end with 51,000kms on the engine... and its holding strong... compression test checks out perfect and every thing still running so you should be fine... plus im running both a supercharger and turbo so im sure if my engine can handle them at 10psi yours can handle 5-6psi
Also every car will be slightly different but with a good tune and i suggest using 370cc injectors (unless you have further plans to go more boost) you should see about 200-215whp....
