NoHachi,

I'd have to check with Bart but he used to have a 12A with mikumi carbs in his sa but he build in a jspec 13B-RET in there so he may have it around. He also has some contact in belgium for getting these engines.

There is very good aftermarket support for the 12A and 13B in the USA. There is a whole culture around it. Support in europa however is alot less great. There are some great shops in the UK and the guys in Tjech have alot of 2nd hand stuff in stock and alot of experience. In holland you have Euro-Rotor, great guy but self tought and he knows he's the only one so he really charges alot. I'd go there if I want to buy a good stock car and maintain it, want something special its much more fun to figure things out yourself and get the knowladge online or from the good USA/UK shops.

I wouldn't go bridgeported, that is some serious alteration to a rotary, you will have no low end power, totally unusable for street. Bridgeporting is only alot of fun for racing. A mild port on a 12A can already bring it near the 200 horses if done properly but it'll be more thristy then a 70ies american V8. Also bridgeport engines don't live very long.

I do wonder where you can get em cheap though, I know some shops sell rebuilds where they've taken an engine, put in new atkin seals and a new gasket kit, do some porting on them (with templates and a dremel tool a baby could do it, well almost) and sell them in the order of 1500 to 2000 dollars. But they reuse the rotors, housings, etc. Which is not a bad thing mind you, if it was a good engine to start with, I will do exactly the same when I do my rebuild but the engine will never be as good as a rebuild with machine work done to the housings and rotors or replacement if needed. But shops doing that sorta work will charge WAY more then 2k for a rebuild engine (but you will have an engine better then new).

When shopping keep in mind a rebuild will set you back about 600 euros in parts (thats the price of the atkins rebuild kit, asfar as I know the cheapest kit with all apex seals and all gaskets and good quality too). Getting a running 2nd hand 12A should cost you only a few 100 euros so doing the rebuild yourself can pay off when you do it right.

Also BIG BIG recommendation, GO PREMIX! Takes a bit more trouble everytime you fill her up but its well worth it. Your engine will perform alot better over time.

Transplanting a 12A into that corolla will be relatively easy, putting a 13B with EFI in a bit more difficult because there is a big lump of junk ontop of the engine and alot more electronics to deal with. Do keep in mind a rotary bolts up a bit weird, crankshaft of a piston engine is low in the engine, eccentric shaft in a rotary is in the middle. There are good adapter plates for it but you may end up with an engine that sits to low. Its worth checking out if its possible using a tranny from an RX7.

Anyways, if you are serious check the other rotary section on http://www.rx7club.com and post a hello message in the europian section. There is alot of information about rotary transplants in that other rotary section, and most of the cool europian guys hang out in the europian section (only the british are hiding away on their own forum which is also worth checking out, have to look up the URL though)
