Get a genuine gasket from VW or if you buy from gsf/europarts etc. make sure it is a victor reinze. If it's an elring gasket it won't last. I've just done a bit of research and the last word on metal gaskets is that they are thinner and raise the comp ratio so go with a standard gasket.
MrkIV gasket has a different part no: 021 103 383 N (12v) It raises compression as it's thinner than the standard 12V gasket. [ Edited Fri Jul 02 2004, 08:25PM ]
I'm sure VW do a metal headgasket for a 12v VR6. I've got the part no. somewhere which I'll post. Yes, you don't want a mk 4 gasket as it raises the compression. You want to lower it if anything.
The current supercharger kits are designed to be used on standard engines and you can probably run up to 10 psi without using a spacer. Most of the time they are only running at low boost, so a healthy engine can cope with this all day as long as the head gasket is ok and the chip is properly mapped.
The supercharger is much better value imo. You can get 250+ hp and 235+ torque. The work you've had done must have cost £2k+ which is the cost of a charger. I think many schrick owners from the group buy would feel sick if they'd paid the full price
engine speed (crank) sensor is on the front of the block, below the oil filter housing. If this wasn't working the engine wouldn't run at all. airlock in the fuel line? Plug lead which isn't seated on a a plug? [ Edited Tue Jun 29 2004, 08:11PM ]
you need spline keys for the drive shafts, 8mm I think. The second picture is the idle stabiliser valve and isv damper. You don't really want to replace this with a mini filter as oil will drop onto the exhaust manifold and the car will stink of oil vapour inside.
Yes you might be right there, the maf expects a linear flow and turbulent air causes havoc with the readings and the ecu doesn't know if to add more fuel or hold back.
Might have to get a socket fitted in the ecu if your management chip is soldered onto the circuit board/unless it is plug and play already. the chip is mapped for a standard engine + supercharger (not for the vgi/cams) so is probably useless anyway unless you put the standard cams back in.
