13B-RE ( Cosmo ) vs. 13B-REW ( RX-7 )
They look different, they are in different cars.
Now how much do they have in common and what can be interchanged with out modifications: Trany, ECU, harnes, intake, exhaust, rotors, housings ... etc etc and what about the size of the ports, the materials used in the engine ..... |
Basically nothing can...
The Cosmo engines come from automatic transmission cars, so you'll need to "adapt" to a 13B-REW originally manual transmission. The exhaust sleeves in the rotor housings have stupid inserts on all Cosmo rotaries (even 20B's). The bearings are all totally different internally, although the 13B-REW rotors should be the lightest. The 13B-REW runs the highest oil pressure out of any stock rotary engine - ~100psi. The 13B-REW water pump is "reverse driven" and supposed to be one of the most efficient water pumps on a rotary engine. The Cosmo secondary intake ports are HUGE - larger than the 13B-REW secondary ports.  BUT, combine both the secondary with the primary ports, the 13B-REW is most likely "bigger" - the Cosmo primary ports are TINY. -Ted |

So what ECU / harness can be used with the 13B-RE ( Cosmo ) ?

if your putting it in an fc it would be easier to use the fc ecu/harness, but the fd ecu is only 2 coil/ignitors and some playing with the cas away (assuming you have an 89+, 88 would be a lot of wiring under the dash)

$1900?!!
I can get you one for $1400. |

What does a 13b-re Cosmo run (bhp) in stock form?

I've been told to run 13b-Re Secondry plates on my 13BT can it be done? anyone tryed it?
As you guys say the Port size is far bigger and would make a quite massive ports as the standard size is bigger it would mean there would be simalar wall thickness and so can open them out even bigger. |
