I'm using a '93 JDM 13BREW as the basis for my conversion. I don't
have any way of knowing if it came from an RX-7 or a Cosmo. I am
going normally aspirated, but the rest of the engine is close to
stock, with the exception of Bruce Turrentine's recommended oil jet
modificaton and thermal pellet bypass. We'll see how it does, I hope
to be done in 3 months or less.
At this point, I'd have to say if I were to do it all over again from
scratch, I'd go with a P port engine. But other than that, I think
that it is a promising engine. We'll see.

the BRE (cosmo ) is the bridge between the new and old technology, the

old ECU OBD 0/ CAS setup but using the newer REW castings,
rotors/stationary gears and TT setup...Two things to consider with a BRE
(cosmo ) the intake ports are the largest made for any 13B series engine
( OEM ) and the Exhaust port is designed to aid in flow into the then
new TT system with the emphasis on bottom end torque rather then top end
HP. also when buying a BRE 90% of the time , in the ones I've come
across the rear rotor has either been grenaded by a broken apex seal or
the seals have been so worn down that they are useless and caked with
carbon and oil sludge from Km's of single rotor running.. a rebuild is
in order 100% of the time.. two other points; the S5 rebuild kit , minus
the gasket set is as close as you will get to a cosmo rebuild kit in
northamerica and the ECU/loom is junk as the ECU is designed to work
with feedback from the auto tranny that had built in stability controls
and the loom is filled with 5kg's of extra ( rats nest ) and tranny
connection crap the best replacement is an S5 ECU '374', and loom. if
you can get an RE or knightsport REDOM/ECU then all the better.
