I got a 89' gl and i'm having a hard time finding an engine for it. It's spfi but im considering changing to mpfi and replacing the ecu but then I seen the xt6! Is the conversion to the xt6 as easy as just switching over to mpfi?

You could do like I did and post an ad in the wanted section of the local craigslist.

I needed a non turbo ea82 for my sons 90 loyale.

A local fellow emailed me the day after I posted the ad saying he had a good running ea82 with about 125,000 miles already pulled from the car, $150 .

The engine has been running great in the car for about 4 months now.

Good Luck.
