Hey everyone, I've had my account here for a while, but I'm usually active on TDIclub because my current car is a golf TDI.
Anyways, my friend has for sale his 1987 Audi 4000cs for sale with a turbo 10v engine in it from an Audi 200. Its cheap, is in decent condition, and I'm looking at picking it up, and possibly swapping a 20v turbo engine into it because I want more power, and I also want to do an engine swap.
I'm just looking for advice on whether this is a plausible or even logical swap to do.
A few things I'm curious about, or need to verify:
1. I've been looking at pictures and it seems as though the 4000cs bell housing will very easily bolt up to a 20v turbo engine. Is this correct?
2. How much power can you put through a 4000cs drivetrain before it breaks? I'll be keeping my Golf around, so if It breaks its not a big deal at all, but I dont want to be snapping things constantly. I want the 4000 to be a daily driver, but still, I will always have my golf, so it doesn't have to be bullet proof, just pretty reliable.
3. Is there any good place to learn about the 10 and 20v engines? I don't know too much about them, and I would like to learn more about them and how to reliably modify them.
3a. How much boost pressure does a stock 20v run?
3b. How much boost can the stock turbo run?
3c. How much boost can the stock engine handle?
3d. If I were to go balls to the wall with this engine, where is a reputable vendor of aftermarket parts for this thing?
4. One of the main reasons I want to do a swap, and not just buy a car with a 20v already in it is for the experience. I've never done an engine swap before, but I'm very confident in my mechanical abilities. I've been around engines for a while, have done pretty big jobs like taking the head off of my TDI, and loads of other stuff. I'm trying to start out with a pretty easy swap. Is this a good project for a beginner?
Thank you very much for any insight and advice.
Hopefully someone here has knowledge of both the 4000cs and the 20v engine will chime in for me.
