[RICE RACING]

4 ports, RR street ported is all you will ever need. There is allot of total bullshit out there and much wasted effort spent on total crap! like extra peripheral ports and totally butchered housings.

I have the largest and most correct validated data base of rotary engine knowledge anywhere in the world on porting and turbocharging, once you know how to separate the fact from bullshit (takes more than a couple of days on the dyno lol) it is real easy to see that you need nothing more than a correctly done street port and selecting the best OE inlet manifold, that currently is the 13B-RE or COSMO, the REW is a much better engine base and it is easy to port out its inlet runner shape to accept the RE inlet manifold, this then makes the best base engine for your application.

On a real simple level looking at the highest boos levels on the turbo I told you about above for street use and using a Tial 1.06A/R V band housing on a basic linear scale as you increase MAP
1bar 225bhp (0 boost)
2bar 450bhp
3bar 675bhp
4bar 900bhp (43psi boost)

You actually make more power at the lower MAP levels due to higher Ve in those ranges but the above suffices to paint the picture for you.

This is all set up on very conservative engine calibration that will live for years on gas and water injection, dozens of cars running this way, all proven and NOT ONE E85 or ethanol FUCK UP NIGHTMARE ever to deal with! EVER!

Simple Reliable, world leading.
