Considering converting to a turbo in my 93 glt. I need some body parts, so I'm going to try to buy a whole car from brim's import, a junkyard that has twelve 94 complete turbo cars alone. I'm curious though, what differences do the engines have mechanically? The turbo is 2.3 where as the na is 2.4 liters. Also, the compression ratio is significantly different. 10.5 - 8.5 I believe. Do they change the crank to give it a shorter stroke which would make less compression and displacement, or do they do something else? What about the pistons? Any ideas would be helpfull. Also, would using the manual trans be a problem?
