My car is running a stock motor. The only mods I know of are a 3.45:1 diff in replacement of the stock 2.93:1 and a higher pressure fuel regulator and a K&N. I consider that pretty stock. The rear end is from a 733i. This car suffers from turbo lag, enhanced by US emmisions and I pulled up on the bumpers of 5.0's just toying with them and was right behind (I started to pass when he floored it and I followed pursuit) a 94-99 TA up to 80 from about 15mph. Then when he braked, I proceeded to severly out brake him even with a failing PS pump.(loss of power brake boost) By dropping off the Cats on this car you will easily get another 10-20 hp to an already underated 252hp. A turbo car is a different breed of animal, to naturally aspirated. There is so much available from so little. Also Torque is what makes the car accelerate not HP. This car creates nearly as much torque as the much larger displacement engines at a moderate 6psi.
I do think that the 745i is more powerful than the M6 at least has much more potential. The M6 has a higher HP rating but I think the M102 creates more torque. I am not saying it is faster, it just makes more power. It is still not a 1/4 mi. machine and I know I would lose any 1/4 mi. race with a pony car but on the freeway is a completely different story. At the track is a completely different story and this is a full size luxery sedan!

Agreed!

I have had a 733i w/ ??? mi. and my 745i has had the tranny rebuilt before I bought the car. I have never had or seen a problem with them. I think that for an automatic it shifts almost instantly in any gear and is smooth as silk. How many times have you read about the trannies failing, and warnings "DO NOT REV ENGINE IN PARK OR NEUTRAL AFTER SHIFTING FROM PARK". Yet some people still find a way. Change the fluid regularly and don't burn out the front clutch pack. Beat the crap out of it and enjoy! I also feel this way b/c the ZF 6-spd in the vette mentioned in the first reply has the tightest shortest throw I have ever felt. It was good in the early vipers too. The Borg-warner in the stangs and newer Camaro's and TA do not feel as good and the linkage has been especially horrible in every manual ford I have ever driven in my life.

Good, then we can agree that there are more efficient ways to create in excess of 300 HP and 300+ ft/lbs than 5.7 litres or 8 liters which I find to be an especially crappy piece of american engineering. I can't afford a new Bimmer until I graduate but I can afford a newer TA or Camaro now and I opted to by a 15 year old car because there are no american or Jap cars I could purchase with the same level of performance in rear drive layout for the money I spent on my 745i. And it seats 4 comfortably and has an interior you would expect to find in a Rolls Royce not in one of the fastest sedans made in the last 20 years.
