People on nopistons have already built 13B's using rensis rotors in them. One guy built a PPort motor using them

They fit fine,k however you have to have the apex seal grove modified to fit the 13B style apex seals if you want to use them because renisis seals are shorter. Once you do that you have to use 13B corner seals also

And the new seal that the renisiss has (something to do with exhaust) on the rotor the people on nopision's didnt use, its only there because the renisis side port exhaust

Mazdatrix has the rotors for sale, and there less than S5 n/a rotors

thats what they said when i talked to mazdacomp, they said the apex seal was 1/2 inch narrower and thats why i couldnt use the seals in replacement for the 13b seals that they were out of at the time. both the salesguy and myself just assumed the rotors were smaller also.

ROTOR 13B 86-88 NON TURBO 11-B100-N3Y6 $527.00
ROTOR 13B 89-92 NON-TURBO 11-B10A-N3Y5 $536.36
ROTOR 13B 86-88 TURBO 11-B10A-N3Y2 $486.34
ROTOR 13B 89-92 TURBO 11-B10B-N3Y8 $536.36

ROTOR 13B 93-95 T TURBO 11-B100-N3YA $523.35

ROTOR 13B 04-ON FRONT 11-B10B-N3Z1 $305.13
ROTOR 13B 04-ON REAR 11-B50B-N3Z1 $305.13

i'd say there's a difference. guess thats how it is when your car is actually in production and not over a decade old and mostly forgotten.

i would say a street ported,and a decent exhaust set-up would make good power with these rotors and could only get better from there( stand alone ecu,injectors ect.)

ah well, atleast we all can look forward to putting renisis rotors into our rebuilds when we blow our engines up for that price.

Yeah, you've got to mill them for the taller seals to run them. Someone tried using the renn seals and they started warping after one race from the PP exhaust. the power increase was something like 20 hp on the PP.
