Hey buddy!
I have had 4 of them in the past, 2 81's and 2 82's.
Would love to hear about, and see some pics of yours.
82 was last RWD 626 in US.
It uses the RX7 rear end, so you could upgrade rear to say a limited slip.(drinks)
It might even be possible for a GSLSE rear swap, but dont quote me on that.(stoned)
I fixed 3 head gaskets, on 3 seperate cars, so it is a definite weak point.(loser)
Carb upgrades are possible, I ported the intake on one of them, but never got around to upgrading the carb, plus, being in CA with all the smog crap, I didn't want to do anything that was hard to fix easy. (stash)
These cars handle suprisingly well with just shock/strut upgrades. Also some nice fat tires are fun too.
If you are really looking for some power, being that it is a RWD car, and mazda, and similar to a Japan only rotary version car, it would be a good donor car for a rotary swap.(boom06)
