I ran the time in my sig with a boost controller air filter and exhaust. Do the math. The aged turbo didnt last long but what do you want for a car with 150000 miles on it. I have some little problems to work out at the moment.
The drive train upgrades are basically beefed up stock parts. Certain years (92.5 and up) have a stronger rear suspension. It is AWD so it has a FWD type tranny a transfer case that has a drive shaft going to diff. in the rear that drives the rear wheels. It is a 50/50 but a stock open diff in the front and MIDDLE. Usually a LSD in the rear though....YES we have 3 differentials. We weld the center one to make things more durable. A slight binding when pulling into parking spaces and the like can happen but your diff. wont break and you can dyno the car.
The only REAL DSM engine is the 4G63 turbo motor. The 90-94 had the same motor with higher compression for the non-turbo. In 95 they went with a Chrysler based motor for the non-turbos that is very close to the Neon motor.
They come FWD in either Turbo or non all years and AWD turbo only for all years.
The 90-94 have a good sized turbo stock. The 95+ have a smaller hair dryer sized T-25 turbo charger. So one of the first upgrades for the 2Gs is a turbo. A rebuilt stock 90-94 turbo on even a 95+ car is good for 12 second time slips and over 300HP. Thats pushing it though.
You only need to ride in an AWD car being launched once. It will make you laugh it is so ridiculous. 1.7 and lower 60 times are not un heard of. 16GAWD on this board has cut some 1.6s. Note the pic of my car. The rear squats the front tires spin a tiny bit. The rears just plant and you go like a bat out of hell. Putting at least a car on most street cars from the start. The traction is where we get our great times. While the other guy is heating up his slicks Im just waiting at the start line concentrating and still put a car on him. Ive pulled a car on some really fast cars for the first 60s or so. Half the time I think they get shocked....punch the throttle....and spin the tires. Regardless traction is our big advantage....except our wrong wheel drive brothers....
