Best Plenum for heavily ported Rb26

[ChakGTR]

I was wondering if anyone can help me out with some advise.

I have a freshly built Rb26 bottom end with all the goodies. Running a GTX3582r Gen1. 1.06 rear housing.

I have a heavily ported head by Lewis. Flows 290cfm. Custom 272 cams by Lewis. 1mm ovwrsized valves and the rest. Springs to handle 30psi. All supporting mods to handle the power.

The car will be used for street with very occasional track sessions.

Does anyone know what Plenum would best suit my application, taking advantage of all the headwork done ???

Stock plenum with ITB's.. Big single throttle body like a Hypertune with larger runners, or maybe something like the Greddy, which flows more but still retains ITB's...

Ps. I only have this head as I bought it cheap.

If I were building such an engine now I would get something from RIPS Racing:

Stock plenum will be fine. Unless you're trying to win sheepstations on the dragstrip, spend your money elsewhere.
