I'm rebuilding the topend of my 95Z. I already have the LT4 hot cam kit, 2.02/1.60 valves. I plan on port and polishing the intake and heads, midlength headers, fuel pressure regulator, accel ignition system. I have to replace the injectors what size do I need? I also found a 58mm throttle body for $200 would that be to much?

 

The 2.02/1.60 valves will fit wont they?

 

The valves will fit but you will need new seats. The $200 for the throttle body isn't bad, but you could put that money to better use. The stock valve can handle up to 400HP.

 

What size injectors would be good?

 

The stock injectors should handle the extra power, but make sure the PCM is reprogrammed to take your mods in consideration, otherwise you will be wasting your time.
