86-91 are heavy and EFI which makes them, in my opinion more complicated than, the 1st gen!

They are no problem for daily drivers, with a BIG street port, headers, ECU upgrade and will have substantial gains over stock parts. Just with those upgrades you should be able to get an extra 50-100hp, but will cost, because the standalones are costly

And of course the TII is the 7 you would want if turbo is what you are looking for!

A rebuild could cost as little as a couple hundred dollars, doing it yourself and not needing to replace any parts. Gaskets are about $100. Then if you need to buy parts, it could get very expensive, you know how that goes!

WATCH OUT FOR:

gray-blue smoke on initial start up, which would mean a previous owner didnt keep the oil level up and hardened the oil ring gaskets. It will run fine for a while, but prep yourself for a rebuild in the future.

Another smoke on initial start up, would be white and disapear quicly like steam. Which would mean the engine gaskets are leaking cooloant into the combustion chamber and that would need a rebuild soon. Would also be hard to start. You could also let the engine idle with rad cap off and watch for bubbles, similar to a bad head gasket.

Iam sure their is more, but Iam not a 2nd gen guy! anyone else?
