I just picked up a pretty rough '85 325e with plans to go FI. I'm planning on swapping the i head in the future BUT I was given a turbo that I believe came frome a Volvo. It's a garret T3 and I believe it is the common .42/.48 AR "Super 60". This seems to be a very small turbo for an M20 and would probably drop boost like mad at high revs... so, should I just keep the eta head for now and boost it as is? I will build the car with a larger turbo in mind, but as this is my first turbo build, I'd prefer to get it running with the small one first.
