i'm installing a turbo kit on my 99 si finally. mileage is about 94,000. the kit is something i've put together. nothing big on fuel delivery other than stock except for fuel pump. for tuning just the basic fields vtec controller. stock internals. minor head work, itr t/b and intake manifold. and just your basic essentials for a turbo setup. just wonderin what safe boost levels i can run with my setup?

 

I would say go with around 4-6 PSI...I wouldn't go more than 7 and that I would think would be pushing it...Considering you have no work really done to the engine... Is it daily driven? That motor can hold over 300 whp on stock internals...but if daily driven will not be as reliable and won't last as long...Another factor is how you drive your car and if you boost it correctly...
