These engines are known as "RPO LL2" with a VIN Code of "R". Also found in the Fiero, they have a FWD bellhousing configuration (starter on driver's side in a RWD rig like ours) but with cast-iron heads.

If I recall, around 125hp and 150 ft-lbs torque.

It's a nice, smooth engine with a lot of Hot-Rod potential. Responds very well to Old School speed parts (cam, exhaust, intake, bigger TBI, etc). Engine parts are readily available and relatively inexpensive compared to most "furrin" rigs. Parts are common to your garden-variety S-10 2.8 (except for the block and clutch kit).

Common problem areas were oil leaks from valve covers, distributor O-ring or the RTV-sealed intake manifold ends. The intakes are also rather notorious for having the bolts loosen up, then you get water in the oil with resultant bearing problems. You just need to re-torque the bolts periodically. Head gasket leaks are less common but known. Exhaust manifold broken studs & leaks, generally thought to be due to the metal-on-metal joint. Aftermarket offers a gasket which works well.

Compared to some of the other "nightmare engines" out there, the problems are relatively benign and after all you're talking about 20-year-old rigs!

Not that bad of an engine to work on and I like the fact that I can run down to the local parts store or the Pick-a-Part and usually find anything I need. Or order up new parts and they're here the next day or sooner. Try doing that with a 4-cyl or later-model Isuzu-built V6!

If you are crazed for power, you can easily replace the 2.8 with a 3.1 (which is just a stroked-out 2.8 with pistons to match), or stuff in a 3.4 and built it To the Hilt.

3.4's were sold as a new "HT" crate motor and also came in '93-'95 F-Bodies (Camaros & Firebirds).

Do a query on "3.4" and you'll find lotsa buzz here and also at the Planet Isuzoo forums. I have info on the swap when you're ready for it.
