Hello every one my name is connor and i just recently bought an FB(82) and i was told by the previous owner that it has a blown rear apex seal. Now i know that this is one of the number 1 issues with these cars but, I need help trying to get it fixed. I have tried the mech shop route and $3000.00-$6000.00 is way out of my price range and that is what i have been qouted at. So if any one around the thornton, broomfield, northglenn areas could give me some help I would be deeply grateful.

Your best bet is getting a rebuilt or good motor and swapping it out.

Thats what i thought. So on that note what would be a good engine the one that i have had my eyes on is

20B-TT EUNOS COSMO
$ 3,399.00
Company: Mazda
Code: 20B-TT EUNOS COSMO
Year: 90-95
Valve Train: 3 ROTARY, TWIN-TURBO
Displacement: 1962 cc
Horse Power: 327 HP @ 6200 RPM
Torque: 308 LBS-FT @ 3000 RPM
Compression: 9.0:1
Red Line: 6500 RPM
Weight: 600 lbs

LOL that is a ton of work to do that conversion. If you wanted a turbo motor, the easiest way to to get a TII motor.

That 20B will cost you over $10k when it is all said and done. And that is if you can do welding.

Going 3 rotor is not that easy. If you were down here in the spring I could help your with ths rebuild. Also number one issue with rotary engine are the owners

ok and i am up north in the northglenn area. I have a 12A engine in it at the moment and a second 12A engine (in pieces and pretty sure not complete). so i need help with both.

talk to Don Walker, he's pretty good at rebuilding our motors

12a are easy to do!!!

i'd be happy to help you restore your 12a (although i have no experience of rebuilding motors, yet) . i'm in the westminster area and be more than happy to give a helping hand

Welcome!

Yeah that 20B would be a major project, not something I'd suggest for someone new to rotaries. Wait, have you ever dealt with rotaries before?

No i have not these are a new form of mechanics for me. ( why cant motors be like submarine diesel's)B)

Buy a rebuild kit and the video. Follow it exactly and you shouldnt have any problems. Rebuilds on these engines are pretty simple even for the average joe. You will most likely have to replace the rear housing and rotor. To get hold of one isn't that hard nor expensive.

ok and i have a second engine with the housing's and rotars so that wont be an issue now how do i get my hands on one of these videos/kits please and thank you.

Atkins and Pineapple both have what you need. Goopy sells fantastic seals and can refinish rotor housings (there is a limit to what they can restore)
