I recently bought a 1997 Prelude(SH), I have some extra cash so I also picked up a Sick APEX-i turbo kit(T3/T4) I installed it myself in my dads garage(he has great tools ) I am currently running 7 p.s.i but I am not really sure how much horsepower I have. Well to cut to the chase, I want to know where I can get some quality parts so I can bullet proof the block(pistons, connecting rods, ect.) I really want to crank up the boost really high like 30 p.s.i I am currently using 550 injectors with a APEX-i F-CON. Should I use 660's for so much boost? I want to beat my cocky friends STi .

 

I'm not familliar with the specs or design of the Apex-i turbo kit, but I doubt it's going to run 30 psi of boost. However to beat your friends STI you won't need to run a full 30 PSI. Anyways, lookup various H-T members Turbo builds (there's a Turbo Lude thread) to familiarize yourself with parts & talk to the builder you want to work with. Remember your block needs to be sleeved. To run 15+ lbs of boost, what you'll need to clean up the STI you'll want some 720's and good engine management. If you want to run 30 lbs of boost a custom turbo Manifold with 3" exhaust piping and larger turbo are going to be needed.

 

the T3/T4, according to the manufactuer can run up to 28 p.s.i. Will this be enough to beat the STi since it has like 350 whp?

 

Sleeve your block

You are going to need much bigger injectors than you have now.
