You nailed the question on whether you can put the 2.5 or the 2.7 or the 1.8 in and run S or A. Chassis has to be the same, meaning you can't 'ceate a car." On a TR7 for example, I'd have to add the battery tray to the trunk but other than that the later shells are identical to TR8s.

Are the E30s competitive? I've seen Chuck's dyno plot and won't disclose the numbers here but let's just say power is decent and torque is out of this world. Chuck's car is reliable and very fast.

I also think the ITS E30 is overlooked because of the E36. Harold Corbin's was very fast (heard he sold it for an RX7 though), and Matt Reppert in Atlanta also has a fast one. Good power, brakes, chassis.

Good luck. I think it is a good, overlooked choice, although Chuck (and Harold) have been proving them wrong the last few years.

are all e30 chassis the same. i.e., can i put a b25 motor into a 84-87 325e and run in whatever class the b25 belongs in?

chuck, how much power do you think you can squeeze out of a b27 motor. i read they are detuned and come with softer retainers/springs and very mild cams. this poses the question of how much power is there really to be had with these motors and how reliable the valve train will be if pushed hard(high rpm)

can these e30 cars win? although i didn't start racing yet and surely do not have the skill to win, i am very competitive and winning will definitely become the the objective at some point. i don't want to go with a platform that will force me to switch in order to be competitive.
