1988 Chevrolet Beretta GTU (The GUT)

Last updated Jan 15, 2009  

Photo of a 1988 Chevrolet Beretta GTU (The GUT)


Bought this car for $800 after it had just received a new clutch and a 100,000 mile junkyard engine and thought I'd have something I could drive for awhile without having to dump money into. Having bought a 250,000 mile car, things were bound to start breaking...and they did. (First the newer engine spun a bearing, then the slave cylinder broke, folowed by the belt tensioner broke, heater core, the power steering pump devloped a leak, the fuel tank sending unit developed a leak...mostly everything has been replaced by now)

If it weren't for me, this car would probably be in the junkyard. I decided to fix what broke and make a reliable daily driver out of it...with a little performance/suspension upgrades to make it turn a few heads and raise some eyebrows. For being a 20 year old car it gets around pretty good and keeps the miles off my nicer Beretta. And aside from the peeling/flaking paint from bad primer at the factory, the paint still shines up pretty well. The car rolled over 291,000 miles on the chassis just last week.


GM 60*V6 3.1L MPFI OHV
Getrag HM-282 5-speed transmission
Swapped in a 3.1L MPFI engine to replace the factory 2.8L MPFI engine (2005)
Stock ratings: 140hp/180tq (tq underrated from the factory)
Best 1/4 mile time: 16.26@81.66 (with bad front motor mount, 2" crinkle-bent exhaust, and was running too rich...I believe the car is a high 15 second car and could pull a 2.2 60' time...can't wait to get it to a track again.)
