Yeah I've seen that one.

In a nutshell the dude gets an M47 crank (needs to be shaved 5mm for pulleys to line up), M3 injectors (s50?) and Euro M3 (S50) pistons that he decks 3.8mm (dont like that, seems really ghetto).

Stroke is increased to 88mm and its bored to 86mm, total capacity 2.05L.

Can't be the S50 stockers. Those are 17.5# ones, the M42 stockers are 20.5#. Must be from something else. Neat buildup...$$$$$ is what it takes.

He's from SA, so you're talking euro S50.
