I recently purchased a 1987 Rx-7 GXL N/A. Since Monday I've been searching for just a really broad answer to my question. What to expect will be the first problem with my engine. I will do a flush, replace sensors, change tires, and paint it. But what will happen if I wait until summer to schedule a rebuild for my engine?

FAQ's help a little, I've read it.

 

REMOVE!!!! Sorry to waste post space, I just read the performance section and sort of found my answer.

Remove Thread!!!!

 

How many miles are on the engine? what was the condition of the car when you bought it?
I would suggest doing the usual tune-up, drain and flush the fluids, check and or replace the belts if they need too, spark plugs that sort of thing.
But if you are already planning on a rebuild there must be a bigger problem I imagine or just high mileage?

 

170,xxx i was going to rebuild it to learn, and because its a high mileage engine, and from now til then, I know I will be pushing the engine.
