Hi,

I'm switching my 2wd plenum to 4x4 plenum, and need some advice.

Was going to keep the actual 2wd inlet manifold on the head, and just switch the plenum over. What else will I need to change? Can I use -

2wd throttle body and all llinkages etc?
2wd fuel rail etc?

Or will I need other parts?

Thank you,

Ben
