Discovered a couple of simple things that improve the S2 performance, particularly in hot weather:
Try removing driver side front light: better induction air flow.
Also remove front bumper: better cooling to intercooler.
Finally: be sure to replace the intercooler to crossmember O-ring with something like the silicone hose below (essential 'upgrade', described here: http://www.s2forum.com/forum/showthread.php?t=193&page=1&pp=15):
Tried those three things while bumper being repaired: good performance, but not particularly pretty/legal.

No, but now that you mention it I should have!
It was really hard to get the top of the hose on to the cross pipe. I ended up cutting the hose a bit too short to make it fit: hope the clip holds!
My result is pretty much like the photo above (from S2Forum):? the top clip doesn't really have enough hose to clamp properly.
here's someone in Sweden who has taken the induction mod to its logical conclusion:

but he may have got a bit carried away with this wastegate vent (I guess that's what it is):

On second look that may be the exhaust exist in front of the rear wheel.
so all those boy racers that do this, have been speaking to you, Simon... haha
Wasn't that a fast-n-furious style silencer hanging at a boy racer angle I saw on your Jetta? ;D
Seriously, the air flow around the headlight to the airbox is pretty restrictive on the S2. Anyway, I won't be driving around without the front bumper until I chrome the intercooler :laugh: :laugh: :laugh:

NO........ its's a DRAINPIPE......... ::)
Agree - air intake ventilation around the front headlight is crape
Doug had a good idea with this
http://www.s2forum.com/forum/showthread.php?t=731&page=2&pp=15&highlight=oil+cooler
mod to the oil cooler ducting with some pipe going up to feed the airbox or filter. A bit more legal! I have done the same thing but my plastic chopping and glueing handywork is not as good as Dougs :)
As for the wastegate dump ipe , are the roadworthy/emission control police in NZ as strict as they are in Australia bout that sort of thing? I am trying to talk my exhaust guy into doing me a seperate wastegate pipe venting to atmospher with no cats/silencers
