do you know how tempted i was earlier to leave work and fit this myself, but im not messing around with this kit, it needs proper setting up, proper alignment and more importantly proper dyno/software tuning, the guys at simpsons will have this kit fitted perfectly and setup perfectly, its what they do day in day out. i have to say it again though the quality of ess's work here is second to none.
VT2 upgrade kit started :-)
- Thread starter Beedub

1. question, are there any markings on the compressor housing that would indicate who the manufacturer is?
2. I dont like the look of the compressor inlet plenum, too many sharp bends. Potential large delta P at the compressor inlet.... check (once the claibration is done) for oil leaks under idle or light load conditions from the bearing housing to the compressor housing.

the charger is made by vortech, its model number v3si, look a few pages back and youll see a link i posted with full details, this charger is hte business, silent operation, helical cut gears, own oil circuits hell it even has its own dip stick, if theirs leaks simpson will sort it!!

No, they're not the same, and they have different part numbers:
However if it's just the guages you are getting to fit yourself—rather than them ready-fitted to an M3 upper cowling—then they should fit in the same position on the Z4M, as the shape only differs significantly at the back of the cowling.
M3
Manually adjust. steering column - BMW parts catalog
Z4
Steering column/trim panel - BMW parts catalog
- M3 = 32311094678 (without phone prep)
- M3 = 32316765803 (with phone prep)
- Z4 = 32316758854 (without phone prep)
- Z4 = 32316765395 (with phone prep)

Not sure if anyone mentioned this but in this months "Performance BMW" magazine there is an article on a Z4M coupe with this exact same supercharger. He's had it up at 500bhp. :evil:
