Ok, I've got an '86 N/A 13B that has pretty low compression in one of the rotors and (presumably) because of that doesn't run very well. I'm quite short on cash at this point, and was wondering what the bare essential parts I would need to repair the engine would be?

I've seen all kinds of prices for all kinds of parts all over, and really just want to know what is absolutely necessary. I've seen the Atkins rotor deal for like... $415 or so, but that doesn't include any intake/exhaust gaskets and things like that. Is it necessary to replace those gaskets if you pull the engine apart?

I'm not really looking for a long time solution right now, just something to get it to run good enough to last for a little longer (until I get money and can get a TII to replace it).

 

I suggest buying a used motor off the forums, it's quick, simple, cheap, and depending on the shape of the motor, a long term solution. I was going to rebuild the 12a in my FB, but I abondoned that project when I realized how much I would have to spend on the rebuild kit, replacing the bad housing, lapping, having bearings pressed, and etc, then the risk you screwed up. The total was well over a grand, mabey 2k, but keep in mind I wanted to do it right and have a long lasting motor. The motor I got from Japan2la was a steal, perfect compression, no leaks, and at $450 it turned out to be a great, cheap, low risk solution to my blown engine.

 

I would recomend you to open the engine and see what is the problem. Maybe is a sticky apex seal that caused the low compression. Opening the engine will give you an idea of how much you will spend to repair the engine and consider if is more cheap to buy a low miles used one. Maybe is a sticky apex seal that caused the low compression. Also you can consider if you have mechanical skills. This will help you to save money that you can use in another parts.
