What size bolt for engine support bar?

dcg78 · 11-15-2018, 12:44 AM

Installing turbos this weekend and trying to figure out the bolt size to go into the top of the engine. Usually the tow hook screws in to this spot but not the case for the Z4! Is there another bolt hidden in the car or do I need to get a tow hook from another model BMW?

Update: I tried the tow hook from my e90 and it worked. However it would only go down a few threads due to the shoulder hitting the cylinder head. I think I will order an aftermarket tow hook...

Many people grind down the shoulder so they can get full thread depth
