Well i just totalled my 88 325 Super Eta BMW and bought an 88 hatchback 4 speed manual, with manual steering, from an old lady. The thing is in mint condition it only has 55,000 miles , but its slow. I know it has a D series engine but im not sure which one, and im looking to bolt in a bigger better mtor such as the d16z6 v tec or maybe a ZC. But are there any other motor options that will bolt to the d sereies tranny other than the d sereies motors? If someone could let me know what they think is a good option that would be great? And i apologize if this is a prediscussed topic im no good at searching lol.
