The 2.2 I got has dual port exhaust, is this a special motor...told is a '95 Imp. Can I get more power by rasing comp, or a low boost turbo? My 2.5 supposedly was blown/overheated...parked for two years. Oil [was] in overflow tank, maybe 1/2 teaspoon, I cleaned it out. It started right up, ran it for 30 minutes. No drips, leaks, revs great, no knocking. Next day drove to fuel station, filled it with med grade, aired up the tires, drove home. I did notice a little steam from P/S motor. I'm pulling and selling it...or redue the heads, then sell for ?
