I got a bullfrog head on the way, they ported my intake manifold and worked my throttle body. I know I'll probaly have to modify the fuel system, so what size injectors should I be looking at for N/A? I've got the intake, exhaust, ignition, and V-AFC as my other mods. Any fuel related suggestions would be greatly appreciated!

 

What are the gains suppose to be like for the new head? I think a stock Prelude can support a 20whp increase without issues.

 

The mod is suppose to gain around 40 to 50 whp!

Hmm that seems quite high. 40 to 50 at the wheels is almost FI level. And this is the sum of all mods or just from the head? If indeed you get that much, then you should step up the fuel system. Perhaps 370cc RC injectors.

30-40 at the crank maybe, probably 20-25hp at the wheel. 440cc's are a good size, i havea s et for sale if you are interested

 

I'm running 385CC injectors from RC on my setup and I'm running a little Rich, but that's better than lean i guess. I haven't adjusted out the fuel settings on the VAFC yet so that's probably the majority of the rich problem.

 

What size are the stock injectors for a 92 si?

 

i have a set if you need some
