I have a stock 94' Z28 M6 and I planing on putting these mods into it, what kind of RWHP should I get ?

Moroso CAI
Granattelli MAF sensor
Throttle body Air Foil
BBK Underdrive pullys
hypertech PTM
Headers (not sure of what kind yet, any suggestion?)
Borla Y pipe
take the cat out
3" straight back to a flowmaster

or if anyone has any more suggestion on ways to get the most HP out of a LT1 without opening up the engine

 

W/ longtubes you should be in the 290's

 

Get nitrous or a blower that will get you moving. What you have listed will be good for around 275 - 300 maybe. I would consider another tune than the HPP go with madz28 or pcmforless.

 

So what would be the best nitrous system to use with the setup?wet or dry?

I'd be looking for a 50hp boost or so

 

don't waste your money ! when I had my car dyno tuned they made me buy another (stock) one because it was screwing the tables up--> and before the tuning it was running too lean with that MAF. keep it stock
