im wanting to turbo my 94 ls next summer since my car will be paid off this dec. I want to push about 10-15psi inorder to pull that off what all would need to be done to the engine to beable to withstand that with no problems? and about how much hp would that bring my car too?

 

You need to search ALOT, and learn alot more before you do it.

 

well I wont be doing it myself a shop will be doing it....I know I gotta get forged internals and injectors.etc.

 

like said b4 man search... to push 15 pds you need money, injectors, pistons, fuel managment... etc... ask the gurus in the FI forum.

 

you need to figure out what type of turbo will suit your hp needs. a t3t4 is a good size turbo... but depending on your setup, you will have to figure out what specifications you want.

with that much psi, you will want to get a Hondata setup. good fuel management and tuning is the key!

 

Im running 14.5 psi(1 bar) daily on my Stock Ls, It is tuned conservatively however. You should base your goals/limits with hp, not boost. Remmeber you can make different power #'s with different psi, due to bigger vs smaller turbo's, and exhuast sizing, ect.... The smaller turbo will take more psi to make the same #'s as lets say a bigger turbo would so kepe that in mind.

As far as your goals, you'll need bigger injectors, An ems, hondata, aem, uberdata ect.... as far as fuel management is concerned.
