1991 GMC Syclone review from UK and Ireland

Besides normal wear and tear, no serious problems have surfaced. The factory boost gauge is notoriously inaccurate, so an aftermarket one is a necessity. I used an AutoMeter one and installed it on the A-pillar. I have heard of water pump problems with these cars, but so far mine has been fine. Turbo suffers performance drop-off. in drastically hot weather.

This thing is a sleeper. Most people think it's simply a modified S-10. That is, until they get spanked. With 280hp on tap from the factory, upgrades aren't necessary, but this truck responds very well to modifications. With a turbo upgrade and a few other mods, a Sy can easily run low 11's or 10's in the quarter mile. The all wheel drive system is great as well. If at all possible, I highly recommend you snag one of these trucks. They are quite rare however, with just under 3000 made.
