4 Rotor FC GXL
ive heard there is a 4 rotor engine/comp/transmission and other parts for sale near me. i havent gone to check it out but i was wondering if it was possible to put that engine in a 86 GXL and if so how much work including custom fabbing is there involved? also if anyone knows of any links to do so please show me. thanks.

that would be sweet,but expensive, the engine itself is prolly 6,000 by itself.your better off going for a 3 rotor, ya dont need it even for a race car, a 3 rotor will make plenty of power,and if you dont do it Turbo, then it will be reliable to, I would just go for the 3 rotor

So uh... by computer you mean Motec, since no 4 rotor has its own engine managment system... add on another 5k+ for that, custom built trans, and a 4 rotor is usually about 100k.

well from what ive heard, havent checked it out, that this engine was in an FC and was running great until the guy was rear ended and the car totaled. basicly everything was pro done and now he just wants to get rid of it at a low price. i know i havent checked it out and there could be and probably is a good bit of BS being thrown about, but i was just wondering if it was even worht my time to go out and see what the exact story is.

Very cool, if it exists. Lots of people talk about building a 4 rotor, but very few actually have done it. I should know, since I am currently in the process of building a 4 rotor 12A. For me anyway, it is a SLOW process, and very expensive. The machine shop that is building the (two piece) eccentric has quoted me $1700 Canadian. The whole project looks to be around $4000 for the engine at the low end, then a system to run it (I will be firing like 2 12As, so I'm just using a Microtech)...It's not really even the money...it's the two big brass ***** needed to pull it off... 
*Please, no one email/PM me about this. I am not releasing any information until it is done.

There's a 600hp 4-rotor PP FD running over here. While I doubt it sees many road miles, from the outside it is a road car, right down to the stock wheels. I posted some pics and info in this thread.
If I were you, I'd still want to actually see this FC before I believed it was ever a running 4-rotor car...

Oops, here's the correct link.
As for whether it's worth it, you have to ask yourself if you really have the finances to build and run a 600hp NA rotary, as well as where and how you can even use it. Personally I think the engine in that car is wasted in anything other than a seriously campaigned circuit car, but that's just me.

There is a 4 rotor short block set up at Mazmart here in Atlanta, it sits on a table in the lobby. Its in front of a big poster of a race car (not the green/orange LeMans car).

Yes he is. The is because most 4 rotor engines built are almost exact copies fo teh r26B. And I do think Downing/Atlanta charges 50-100k to have them build a 4 rotor pport race engine.

Short answer: no
Long answer: yes, but you also need to modify the intermediate plates for stationary gears, make peripheral port housings, build an oil pan, modify the cooling system, make long and STRONG (ie. inconel) tension bolts, build a proper (dry sump ideally) oiling system, mounts, manifolds, EFI system to run it all, etc....Not a simple task by any means.
