Hahaha. Thats funny.

I just did this pal. Heres a brief on what you need.


Running 13B out of either a GSL-SE or Second Gen.

GSL-SE Oil Pan

GSL-SE 13B Front Cover OR you can use a 12A Front Cover, which is what I did.

And the racing beat 13B to 12A Chassis Engine mount. I heard mixed comments about the stock GSL-SE engine mount.

Everything else bolts up. Tranny, clutch, all that stuff and whatnot.

Also need to address fuel issues.
If you have a 12A first gen, you will need to change fuel pumps. If you plan on staying with FI then you will need ECU and harness. IF you go carb, you will need to have some knowledge of tuning carbs.

Go carbureted. You'll never get the EFI to work in the 12A chassis unless you get a Haltech.


I bought my engine used out of a car that already did this swap. So for about $2000 Total I got:

13B Shortblock Street Ported with 30,000kms on it.

Racing Beat Header

Racing Beat Holley intake

Holley 600CFM 4 Barrel (A Little big but good enough)

Holley Red Fuel Pump.

And a few other things.

If you go carbed, dont forget to plug the injector holes.

If you rebuild the 13B and want to go carbed, you have the option of using a 12A centerplate. It has no injector holes and potentially larger ports.

i will probably be doing the same thing. it looks like im buying an 85 gsl that sat for 5 years, and the engine won't run. i plan on doing a 13b 4 port swap, streetport, carb'd, and all the other bolt on's. (eventually of course)......till then i just may try to get this thing going, we'll see. can't wait to pick up the car

I'd like to use my 12A irons with my 13B rotor housings, but on the 12A the grooves for the oil and water seals are in the rotor housings. On the 13B, these grooves are in the irons.

Never get the EFI to work in the 12A chassis huh!?

http://img.photobucket.com/albums/v2...y/DSC01389.jpg

A S4 EFI 13B (turbo or not) is not that hard to transplant into a 1st gen.The SE oilpan and front cover are the main parts needed to mount the engine.Stock SE mount plate can be used if you purchase an SE right side rubber mount.Or just notch the plate a little.

Youll need an SE fuel tank,or weld a baffle box into the 12A tank to prevent cavitation when the fuel level is below 1/3 full.I just used an entire TII drop in pump assembely and welded the baffle box into the base of the tank.Youll also need a full size fuel return line,another stock 1st gen feed line works perfectly along side the original feed line.

The S4 EFI wiring is NOT hard if you can read a wiring scematic.75% of the wiring is plug and play on the right side harness.The left side harness requires you to run about 10 new wires to power the fuel pump,ECU power,coils and CAS.If you purchase a factory service manual for the correct year car that the engine came from,then its very easy to figure out all the wiring.
The S5 engines are more powerful,but more fabrication is required to install them since they have more electronics and the OMP is not compatible with an SE front cover.I did my S5 swap last year and it wasnt too bad,but it required some custom aluminum work on the SE cover.The S4 swap I did easily in a few months of planning and only a week of work.Before that,I had never worked on an EFI rotary,ever.Its not that hard,you just have to be throrough.

I tired for a month straight and couldn't do it. I would also like to point out that I have an SA22C and The wiring is limited. I also had no help or schematics (Aside from the FSM and Haynes) until AFTER I purchased the Racing Beat Manifold for the Holley. The only schematics that I could find were for GSL-SE. But the directions were step by step for a swap of a S4 TII into an 84' GSL-SE.

If this is the first swap you've done, or your knowledge of the EFI is limited, Go Carb'd first. Trust me, its painless if anything. Haltech's cost around $1500. Its alot, but the advantages are vast in the tuning realm. I used a 600CFM Holley on a 13B 6-Port Agressive Street Port and its too big. Go with either a Racing Beat Carb and use the stock OMP or you can go with a Holley 390CFM and Pre-mix. Manifold is $360CDN and the carb is whatever it costs you. Dont forget to plug you injector holes, you can use the stock injectors in their place, but the fuel rail requires some mods to fit because of the Holley Manifold.
