I'm a very happy owner of a 91 Trooper LS, with 2.8 V6, 5spd. I purchased her last year, with a shop quote of "beyond repair" engine damage as told to me by the prior owner. It had 150K on it, and on start up, blew oil in a massive stream out the left side of the motor. Being mechanically adept, having fixed everything from tote-goats, done engine rebuilds in snowstorms (grew up in Montana) and flight mechanic on military airplanes, I figured I could fix this too. But, never having seen a trooper up close and personal before, let alone the highly asteemed GM 60 degree v6, I had no idea what the problem could be.

So, I bought this critter for a very decent price, and once it was home and in the garage, I got to poking around under the engine. Found the oil filter seal had blown. I replaced it with a $4 Fram filter, and it worked great... for 2 weeks. Then, this new filter blew a seal as well. Fortunately I was less than a block from the house and hurried back into the garage. I now need to use the $10 Fram filter, (XG model), but have put 30K + miles on this thing, and absolutely love it. My oil pressure however is high, above 55 but below 110 (there are no markings in between these two numbers). My guess is a plugged PCV.

Anyway, to make a long story just a little bit longer... My new-to-me Trooper that I dearly love, is starting to show a that a little bit of it's git-up-and-go-has-got-up-and-left. And even though it still does run great, and feels fairly strong yet, I read the threads on how to get more umph from a tired 2.8L, but am now having thoughts remininscent of Tim the Tool Man Taylor ("More Power").

I found a '93 GM V6 Vortec engine for a fair price. Don't know yet what it came out of or the displacement. But am curious, from what I could find, this may, or may not be, a 60 degree motor. And it could possibly be a 4.3L. It does have TBI though.

Will this bolt right up to current 5spd? IF so GREAT!
If not, what mods would be required to get it inside my Trooper?
Or, what other motors will bolt right up, without doing any major mods?

I will post the eng. size, and vehicle of origin, as soon as I get a reply from the seller.

Thanks
