Why we don't see more than 16-17psi on an FD with a IHI RX6 Turbo?
I'm currently looking for a turbo and I didn't see an Fd with RX6 P27 setup running over than 16-17 psi. Is it because beyond that point it push to much hot air. We see 20-25psi on an MR2 with a RX6 P25.
Which turbo do u think is my best bet : BNR stage 3 or IHI RX6 P27?

The BNR Stage 3s will spool faster (seq) and make at least as much power at the same boost levels. You also don't have to do all of the other work associated with installing a single turbo kit. All that said, if I lived in a state without emissions checking, my car (which is only a weekend/track car now) would have a single turbo.

You better go single if you want to chase Chris's monster...

I've driven three FDs with that apexi kit and in my opinion it is NOT worth the price they charge. The hotside it way too small. Sure it spools well, but it has no high rpm pull. That turbo is more comparable to the stock twins in terms of power output. The BNRs are more comparable to a T-78 in terms of power output, mods and boost being equal.

How come some people from the Mr2 board (mr2oc.com) make 630 whp on a 4 cylinder engine with a RX6 P25(A/R 0.98)...while you guys say you make only 400-440 whp max with a RX6 P27(A/R 1.06)
pleas explain why?????
here is the link to the Mr2 that did 630whp

rascaca: Don't forget that our cars are only 1.3s. (Talent)Vince's car is stroked if I'm not mistaken. I'm pretty sure it is at least a 2.2. A lot more displacement there to play with. BTW, I miss my MR2.

This has been explained many times on the forums.

If you perform a simple search, you'll see that many rotary owners run 25-30 psi, but on high octane race gas.

What max said , the air pressure is not allowed to build up in the intake manifold , since the motor uses it faster than the turbo can supply it.

like what most stated, the turbo isn't big enough to produce the flow at higher rpm to support higher than 17psi. You can set the boost to 25psi and it'll stay there from 4krpm-6.5krpm and then drops down to 17psi from 6.5krpm-8krpm. it has nothing to do with the wastegate or the engine. Rotary engines require higher CFM to flow the same amount of hp as the piston engines. That's why we need at least a T66 turbo to get 500rwhp while a honda can get the same with a GT28 turbo.
I have tuned enough RX6 turbo to know that they won't hold more than 17psi consistantly above 6.5krpm.......
