I just bought a 86 n/a the other day, it runs great and looks pretty good too. So now i want to start getting stuff for it. Here is the list so far...

air intake (dont know which one yet)
radiator (koyo)
exhaust (racing beat)
10mm magnecore spark plug wires

I have a electrical ground wire kit in my closet i bought already. What should i add to the list?

 

A full tune-up first is the best thing to start with, then go with exhaust and intake, you don't really need a larger radiator for a non-turbo.

 

New plugs, wires, vacuum lines, oil, MT90 for the diff and tranny, shocks/struts, springs, solder, suspension bushings, motor/tranny/diff mounts, whidshield washer fluid, new wipers, upholstry, carpet...

Anyhoo, that's what I can remember what I've done so far. I havn't even started on "Improvements".

 

Actually the previous owner did a tune up, he checked all the vacuum lines and everything. He was a mechanic for a race team.
Ok so here is the revised list...

oil change
tranny fluid
suspension bushings
plug wires
spark plugs
air intake
exhaust
wheels and tires
speakers, headunit and amp
shocks/struts
springs

The carpet is pretty good, the seats are cloth and have some stains but would be fine for now, mabey just some seat covers. I want mazdaspeed seats later.

 

no need to get a radiator, unless your current one is failing

 

Search, I can no longer even count how many times this has been asked, discussed, posted about, etc.
