all I read was someone ignorantly saying rotaries need rebuilding after 60k or whatever. He's wrong.
Non-turbo Rotaries can last a LONG time without rebuild. The engine is probably good. I had one of those cars myself, freakin loved it.
Anyway, speak with ColinL if you can, he told me someone he knows just bought a 3-rotor w/ tranny from Japan for only $2k. Yes, I will be doing the same, just not putting it in an RX-7
And just so you know, the FC engine bay was built specifically to fit a 3 rotor
but if it's in decent shape, and is under a grand, you can't pass that up.
