I am currently building a turbo h22 and looking to add some fuel injectors. I just wanted to know if anybody know the size of the stock fuel injectors. I seen some from rc with a few different size and wanted to see if you guys can help me pick out what should be right for my setup. This is the setup I am doing.

1997 Honda Prelude SH
H22A4 Sleeve Block done by http://www.ForumRacing.com
Port and Polish head done by http://www.portflow.com
Turbonetics T3/T4 Full Turbo Kit
AEM Fuel Rail and Fuel Pressure Regulator

Basically I have all the other parts I need except the fuel injectors. I rather just change the fuel injectors so I don't max the stock ones out.

 

440cc= 330whp
550cc=380whp
650cc=425whp
750cc=485whp
880cc=525whp

Those are pretty good estimates of the max WHP the size can support w/ stock fuel pressure and 90% duty cycle. Choose your goal and go from there.

well i am estimating around 350 or more whp because the block will be built with parts to handle the boost. So i think going with the 750cc injectors should be good. thanks for your help.

It's always good to be able to have room to play with. Good luck

Im not trying to start an argument, just curious but where did you get those numbers from? They seem a little optimistic to me.

If anybody wants to trade I have rc 550cc's. I need 750cc rc's. I'm gonna be maxing them out at 18psi. They work GREAT just need bigger one's.

 

i have some new 750's for a good price.

Not at all. It's how much power you plan on making.

There are to many variables just to say that "xx" amount of boost will yield a certain WHP. He said he is going w/ the 750's anyway.

Well the amount of boost im going to be running depends. I talked to many different people and putting parts people recommend and have use with similiar setup. I woudn't know the exact boost im be running until I take the car to get tunned. Anyways thanks hondaguyef for your help. I appreciate it.

 

im at 400whp with 750cc at 60% duty cycle
