I know exactly what you mean about owning what is possibly the slowest bmw ever. I had a 98 Trans Am a while ago, which i also put to rest a while ago, and they are great cars. Even buying an M3 wouldn't be enough power, stock anyways, to show up an LS1. If you want to piss off your friends with the pontiacs just stick with the 318. Dont worry about a stroker kit, just upgrade to higher tension valve springs, replace the valve's, get some forged piston rods, and make sure the 318's bottom end is at least balanced. Then get a small turbo with the capability to boost about 10-12 psi. With this set up and minimal tuning, 14 sec et's will be within your reach. Personally, i would rather have some v8 muscle bowdown to my lowly little 318i, as opposed to a M3. Besides, BMW's make much better track cars than drag cars, who cares about the quarter mile??? Turbochargers are a dime a dozen these days, they get more inexpensive all the time. Although turbo exhaust manifolds seem to be nonexistent for the 318, it is an easily overcome obstacle. Try talking to any exhaust/muffler garage to see what they might charge to fab up a header if you can bring in 1 or 2 old manifolds from a junkyard. Or just start calling any tuner shops around your state. You never know what you might find. Or you could fork out the $14,000 for a M3 with 140,000 miles on it that may or may not turn a fast et. I love having 4 doors now, and my 318.
