1. Can the steel compresser wheel handle a bit more boost than the nylon wheel in the series 2?

2. Do they have coilpacks or spark plugs? or both?!

1) supposedly, although i still wouldnt go past 0.85bar

2) Both, spark plugs and coil packs are 2 different things.

Apparently the S2 turbo is stronger and spools up quicker.

the series 2 has a bigger exhaust housing (only slightly) but to be honest there isnt much in it....

series 1/2 both have coilpacks and plugs, but the series 1 has a ignition amplifier, at the back end of the coilpacks.
