I am considering building a Spec30. Although NASA is not active in the NW, a Spec30 car can run in ICSCC production classes. Besides, one of these days I’d like to run at Thunderhill!
There are a whole lot of 325e here in the NW (eco-friendly) and their sale prices are reasonable. I also have an option to purchase a very solid 325i 4-door. My question is this: is it relatively simple to convernt the "e" to an "i" (engine change and all) or are there any disadvantages in running a 4-door?
Thanks for your help.
