Twin throttle bodies for RB20

[AlexR31]

Skyline People,

I have managed to get my hands on 2 complete RB20 ECCS manifolds and am trying to work out the best way to go in building an intake with twin throttle bodies. I need to move the throttle body to the front of the plenum to reduce heatsoak on my intercooler plumbing so.....

Which would be the better option in your opinion:

- Running two throttle bodies side by side on the front of the plenum may have to customise it a bit

- Running basically two intakes, one throttle body has runners that feed cyls 1,3,5 and the other feeds 2,4,6

- Running basically two intakes, one throttle body has runners that feed cyls 1,2,3 and the other feeds 4,5,6

Just trying to work out what would be more efficient. Would there be any dramas with additional injectors? Would I get equal air flow if I just put a fork in the intercooler plumbing before the throttle bodies?

Thanks
