I need your help please
I am looking to buy a used 1988 RX-7 turbo. The body is in good shape, but that don't matter because i wil be doing slight modifications to the body. From what I was told from the owner it has a 130,000 miles on it and runs ok. What should i do. I really don't know too much about rotaries so i don't wanna get screwed and have to rebuild when i get it. As far as i know it doesn't have over heating problems either. Thanks for your help.

Go and get a commpresion test done to it first off, if thats ok ask him how often he checked the oil, and changed it other than that any car that i didnt own that already has 130,000 on it id be a little nervous, especially if you plan to modify it get it, and just be ready to replace the engine or rebuild. also i would go ahead and do all the bolt ons and when you first start it up make sure it dosnt smoke to much, a little is expected.

To add to that, T2 engines seem to last anywhere from 100-180k as a rule - so you're pretty much getting near the end of its lifespan anyway. (Ask yourself why the owner is selling - if he's savvy he probably knows that it might fail soon)
On the bright side: When doing mods it's typically best to start with a fresh engine, and if it still has decent compression the housings and rotors are probably in good shape. Since you'll have to get it rebuilt anyway, now would be the best time to get it done, because it'll be much more inexpensive compared to if you blow out a seal and wreck a housing or two, a rotor, and blow crap into the turbo and wreck that too. (Seal and gasket kits: $800 + $200-300. Rotors: $400 or so each, housings $350 or so each, turbo= big $$$) Plus while it's apart you can do some porting as well.
Hey, the car will be out of commission while you do your planned body mods anyway, right? High time to get the engine work done. It's fairly easy to rebuild one of these engines if you have mechanical ability, because they're so simple. Only 3 major moving parts, disassembly is a snap, only 17 major bolts holding it together... much nicer than a boinger with a few dozen bearings and a zillion bolts holding it together and enough specs to measure out to make you dizzy.
