I do all the mechanical work on my cars. 70 GTX, 88 Conquest TSI, 71 Challenger and a 91 Stealth R/T. I have swaped engines and trans, as well as all brake work and clutches. Valve jobs and timing belt changes. I have a modded engine in every car. I changed the struts in my Rice muscle and lowering springs. I just can't seem to leave these cars stock. I also work on my two sons cars with them so they will learn how to do their own work. My oldest son has 4 cars and my youngest has 2. We have modded every one of them. From upgraded turbos and cam changes to high volume oil pumps and headers. Even my sons 2006 Charger Daytona has intake and exhaust upgrades. We just put a clutch in his 3000-GT on Friday. And we are pulling the engine in his Conquest next week end to put forged pistons and a rebuild of the bottom end. My brother works at a machine shop so we let him do our blocks and turn the cranks. He also does our heads and we order our parts through him. So the only part we have not done is go into the transmissions and we have just recently started to play with body work. We painted the white stripes on my sons black Stealth. And with our new compressor we plan on doing a lot more body and paint work. Its not as hard as it sounds. Just read alot of Hot Rod and Car Craft mags, they tell you how to do most all of it. And the new cars are just as easy. They have mostly the same mechanical build up. but I will say that my sons Eclipse GST is real pain to work on, talk about no room. But that little car is one quick ride. The oversized intercooler seems to be real big help on that little beast. That car is awsome from a roll. So get in there and get your hands dirty. I will try to talk myself out of modding the 2008 Challenger and leaving it stock... but my track record aint too good.
