1983 BMW E21 320 ITB

Build030 1983BMW E21 320 ITB M10 190

The plan for this build changed a few times as we were doing it.

At first it was going to get an S54 (yes I know!!!) and wish we would have stayed that route. Then the owner wanted to go turbo M10. Okay, okay, I can get on board with that. Then as it went along it ended up NA ITB M10, but the engine was built with boost in mind.

While it was here, we swapped to euro bumpers front and rear, along with all the euro rear sheet metal. It got resprayed, all new suspension, and some interior bits were done at the same time.

Euro rear metal

When swapping from US bumpers to euro bumpers on an E21 you end up with a very odd under bite.
