Hey guys.. I was able to get all my US spec parts problems squared away.

If the crank has the three threaded holes in the end web, it's a double Vanos type. The single Vanos cranks don't have the TDC trigger wheel and thus no holes. Non vanos cranks clear the later 8.8:1 pistons easily. That might be true in Europe but in the US the M52 engines used in the 328i are OBD2...

The crank didn't come out of a M52B25 double Vanos engine but it does have the 3 threaded holes on the number 6 cylinder counterweight where the CPS sensor wheel was mounted. Just as you said the counterweights almost catch the piston wrist pins. I went ahead and machined one down until I wa able to...

I will note that it if I hadn't already had the crank polished and balanced I would have had the shop shave the counter weights 5mm so the skirt shave would not have to be as aggressive. Ooh, wouldn't wanna do that meself. The counter weights are there and the size they are for a reason so if you t...

My build is on a budget. So far I've collected everything I needed for free including the M52 crank. The piston's are from an 87 325is engine and are the 8.8:1 CR. TDC looks to be on par with the pictures in this thread and after doing some custom machine work to the pistons I was able to get a good...

I'm in the middle of my 2.8 build when today we realized that your M20B25 pistons are much different from the M20B25 pistons that came from my 87 325i M20B25. From your pictures it looks as if there is a definate different between the 2. The problem I'm having is that the crank is touching the pisto...

Sweet... so that means I can use the rods from an M20B27 with my M20B25 Pistons on a M52B28 crank to pull off a 2.8l M20 stroker?

Sorry if I might have missed it, but are you using stock M20B25 rods and pistons?
