Custom throttle bodies

[luvemfast]

I am building a custom ITB injection system for my car, building upon Justin Olson and Ron Tyler's previous work from HybridZ.

 

I have a mechanical engineer at work helping me out on this, and will post progress as we go for others opinions.

 

What distance would people recommend from the valve to the throttle plate on an L28.

And runner length before and after throttle bodies.

 

Keeping in mind that I want to use the plenum still so that it can use the AFM and even be used for turbo applications, for anyone else who wants to.

 

Thanks, Simon

i'd have a look at the rb26 plenum as a start,you might even be able to use the ITB section with custom runners? i know they do this for that plenum on the rb25 heads
