just dont get a UNIVERSAL turbo setup go somewhere and get a custom one if your already dishing out tha cash.
shouldnt be to much more. but well worth it.
keep it around 8-12 lbs boost and u should be ok.
i would set it at 8 for street. if u get some rods and good pistons maybe 10-12. but hey you could set it at 15 and still be ok? hehe.
