Okay i have a question. What would any one do in regards to engine upgrade. Keep the M20 with a chip, stoke the M20, swap to a S50, or turbo the M20. My main concern is to keep the car reliable, but gain some advantage. I don`t want a M car, I love the E30, and from what I hear it`s the best 3 series to date. What does everyone think about what Mod to do. I don`t know what exactly I`m going to do, so I thought that I would ask the question and see what the concensus was.
