help, looking to build a bad a$$ 6-port?

I would be interested to see what it would do, either with stock rotors, or high compression rotors.

I am going to build another FC soon, and am going back to NA. Only every other car can be boosted

I have heard that the RE intake is the best flowing intake for a 4-port.

I knew a guy who put down 202 WHp on a dynojet using an RE intake.

I think that GtoRX7's FC has an NA 13BRE in it at 230 WHp.

I would expect that 215-225 WHp is reasonable to expect NA.

fair ?, is the REW intake good in any way for N/A performance?

The intake manifold-to-port matching will be so terrible, I would doubt that you would see any gains from the RE manifold.

I have heard of converting a 6-port to a 4-port by removing all the material between the ports, the sleeve, etc. I think this port would be way too big to make power at any reasonable speed or with the intake runner size that even an RE manifold has.

I am thinking that a custom intake (for the 6-port) with short runners or ITBs is your friend.

for ITB's, would 4 38mm throttle be big enough?

for a SP or even a half-bridge?

I don't know what manifold you would be using, but I think that 38mm would be a little small for the secondaries (plenty for the primaries).

I saw a couple builds and they both were using 3 48mm TBs, one for the two primary ports and one for each secondary port.

3 44s would probably be sufficient.

This flows about the same as 4 38s, but the flow into the secondary ports is a lot higher than the flow into the primaries and needs the throttle sizing to be correct.
