All,
I also did some investigations on a BMW inline six, however the size is not
the problem. It's the design of the oil pan that doesn't fit. I recently had
the new 3.0 Z3 for a weekend and of cause, I checked the engine. BMW use a
different oil pan, similar to our TR6. I think, from what I see, this engine
should fit. I am currently in contact with BMW to figure out whether the Z3
oil pan can be used on a older 2.5l engine block (easy to get from a scrap
yard).
Unfortunately, I do not have a response yet. But I am pretty sure that they
didn't change the bolt pattern on the six cylinder blocks. The 5 speed
gearbox would be perfect for the car!
