technically...
13b can be any 1.3L production rotary engine. They are all 13b, regardless of which year/version/aspiration.
13bt = 87-91 rx-7 FC turbo II engine, single turbo, 185-200hp (also put into some early cosmo cars)
13b-rew = 93-95 rx-7 FD twin turbo engine, 255hp
13b-re = JDM cosmo twin turbo engine, 235 (?) hp
13b-msp/renesis = rx-8 obviously
There were also several versions of 13b natural aspirated that were not produced with those codes. These were
89-91 rx-7 13b non turbo 6 port, 160hp
86-88 rx-7 13b non turbo 6 port, 145hp
84-85 rx-7 13b GSLSE 6 port, 135hp
As well as previous carbureted 13b engines in previous models that I am not sure of the hp ratings on, but they are scarce enough not to really matter any more.
Looks like the engine in question is a 13b-re with a 1st generation rx-7 front cover. I'm curious why you didn't just modify the intermediate and front irons to use the stock rx-8 motor mount system, which would probably be pretty easy to do?

A couple questions/issues:
1) How is the shifter going to fit in the stock location with the R-type manual transmission? I thought they were in different spots? Or are you using the FE tranny and drivetrain?
2) What are you using for a throttle cable?
3) Fuel system: are you running stainless lines through the whole car? How are you going to plumb in the return line to the tank?
4) Engine management: Are you building your own wiring harness? You pretty much have to, or seriously modify a series 5 Rx-7 harness and run a Power FC. You will need new SHIELDED wiring for the alternator and the crank angle sensor (or go for a Haltech Hall Effect sensor and delete the stock CAS). What EMS are you going with?
5) How are you going to make sure all the accessories work with the CANbus system? Cruise control will be difficult, but might be possible if you swap in all the parts from a series 5 turbo Rx-7. Are you planning on keeping A/C and power steering? It's going to be tricky with the P/S because I thought the Rx-8 uses an electric system and the 13B-RE of course uses the traditional pump and pulley. Clearly you will have no traction/stability control unless you have a standalone capable of it and switch to their wheelspin sensors etc. But you said this is going to be a track car so I guess you can toss most of that stuff out the window.
6) With the way you are mounting the 13B-RE, will there be enough clearance for a turbo manifold, external wastegate, and a decent size turbo? I hope you weren't planning to run the stock turbos, the HT-10's on the 13B-RE are significantly smaller than the HT-12's on the FD. You could run a series 5 hybrid turbo though as has been suggested. That would save on cost, but is it really worth it for only low 300's to the wheels? And are you keeping the RE exhaust sleeves or going with the FD sleeves?

wow
that is a lot of questions
ill try and answer most of them,
with regards to the engine bay all the holes and panels have been filled and welded which i did myself, prep work and painting was done by my mate.
The reason for mounting the engine with a first gen front cover is because it actually simplifies things to allow more room on each side of the engine for a turbo manifold with equal length runners, single turbo, as you can see my car is right hand drive so the steering colum is also in the way. the other side will also leave room for coils, alternator, ABS and what ever else i can fit there. the car will have registration and be fully engineered. rx8 6sp will be used for now untill i can afford something decent and the wiring harness will be modified to suit relevant changes and every thing else i.e steering and traction controll which im not fased by any way since i never used it in the first place.
A complete new fuel system will be fabricated and including all new lines and pumps. A mechanical throttle pedal will be instaled to cater for a cable actuated throttle. The ecu will be a microtech Lt10s, and the engine bay and car will stay winning blue for now.
i think that is every thing

for any one still interested, sorry for no updates but i had to move house and have been renovating for the last 6 months. so any way in the mean time i got my new motor back and my kit has been installed and the car is now at the work shop where most of the work will now commence.this is my new power plant ready to go in. it has been ported and completely rebuilt and with all new parts and has an 'Extreme Rotaries' 14mm studd kit.
