Hey everyone,
I'm new to the forum so please go easy on me. I've always heard that this was the place to go for all your E30 needs so I'm hoping someone can give me some suggestions. I'll start off by admitting I don't know a lot about cars and a majority of my work is done by a shop I know really well and trust. I simply like driving my E30.
I have a 1988 325iS with about 170k miles on it. I've been putting a lot of work into it to get it restored and now I'm thinking about having some engine work done, although I'm not sure what to do.
I recently did a leak-down test and all of the cylinders were between 10-14% and one was at 22% lost. What I can't decide on is if I should just replace all the seals or do something more drastic like the 2.7L swap from the 325e or maybe even a new motor all together (S52). Again, not knowing very much about cars, are there kits or places I can go to which will handle getting all the parts I need in order to do some sort of swap? I would love to put an S52 in my car but I would have no idea where to get all the necessary parts (or even what I would need).
What do you guys recommend or suggest? I appreciate all the help.
P.S. Here are some pics of my car
