Hey,
I've just bought a very clean 1990 Rx7 Gtu with 126,000 miles on both the chassis and engine. I was wondering if i can get any pointers for the type of maintenance i should do and what i should know about the b13 to keep it running for as long as i can before i swap it for a turbo II b13.
Thanks

 

Welcome to forum

 

the shop manual is here, Foxed.ca - Mazda RX-7 Manuals

there is a section in the front for pre delivery inspection and maintenance, and just do the whole thing. car is actually due by miles for the major service.

 

Welcome to the forum. Like the others have stated, check out the FSM. After you get that done, stay on top of oil changes (especially important for this car) and check your oil level regularly as the engine burns some by design. Consider premixing. Lots of info if you search. Let the engine fully warm up before you start driving it, and never shut it off without letting it warm up to avoid engine flooding. And remember: a redline a day keeps the carbon away
