I have a 1988 Toyota Celica GT4 (Alltrac Turbo) with a bad engine and need to replace the engine. I was hoping to put a rotary engine into it but I can't find any resources... Any help would be AWESOME! My ideal build would be to start with a 3 rotor engine (I don't care what it is) and modify it into a 4 rotor. All the forums and papers I've read seem to indicate that this is a VERY hard build but I can't seem to figure out why? I have a shop and lots of help from pro mechanics and welders so I'm thinking I could get the pieces and parts build for MUCH less $ than buying the parts and also get them custom fitted to my needs? Also what type of transmission would I be looking at to leave the car AWD and swap a rotary into it? Thanks all!

What are your goals? Do you want the 4th rotor to reach a certain power level, or just for the wow factor, or what?

i'm not sure the drivetrain would even handle a 20b. they were pushing about 300hp stock whereas the model celica you have had 190hp max. furthermore there are fitment issues. the twin turbos are bulky and the piping for them takes a lot of room, the trans isn't going to mount right onto the rotary without an adapter plate which will extend it out further towards the side of the car, and the motor mounts will all have to be custom made to support the engine. i wouldn't do it but it's your choice.

A 20b is not going to fit transverse.

To the OP I'm going to be honest with you man, what you are looking to do is going is probably out of the question. The cost & fabrication will be extensive to say the least. Like said above why the need for a 4 rotor or even a 3 rotor? You can make a decent amount of power with a 2 rotor. Back to cost doing a custom 4 rotor out of a 3 rotor will require someone to make you a E-shaft & I'm not too sure what you would do about the extra plate/iron needed. Not to mention the the manifolds will have to be made both intake & exhaust. I pretty sure that if you did succeed in getting the motor figured out, you would have trouble trying to fit it along with some sort of AWD drivetrain in that chassis & if going the boosted route the turbo & associated pipping would be an even bigger issue. You say you have pro mechanics & welders to help which may sound nice, but the realization is that these guys are not going to do the level of fab work & make the custom parts needed for cheap. Now with that said don't forget the rest of the car (fuel, ignition suspension ect.)



On a side note why not ditch the factory early 3S-GTE for the a newer updated 3S-GTE form the 94-99 chassis & retain the factory AWD. The 3S-GTE is capable of making decent power, but then again with no indication of what the car's purpose is who knows right.



Damn I just noticed the date of the first post, oh well he may see it LOL.
