Get one thing in your mind from the outset, tuning the VR is expensive.

OK, the 2.9 engine was restricted to less than 200 bhp to fall inline with German insurance policies. In the 90s, german premiums rose dramatically if the car gave more than 200bhp. That's all changed now but it's why the Corrado, Merc Kompressor, BMW 328i (E36) were all under 200hp.

The VR's inlet is restrictive, quite deliberately so.

First thing to do is email alpina527@aol.com and get a big bore throttle. This is no quick polish job, it's a full on rebore with a larger butterfly. This will give you another 10 pounds of torque and make the car feel much perkier across the range.

A VSR or Schrick manifold with 268 cams will give you 220bhp easily. Indeed this is the power UK racing teams were supplied with from VW, guaranteed. And they didn't use a Schrick!

If you want punchier acceleration, dump the Autobahn orientated 3.39 diff and fit a shorted 3.68 one from a Corrado G60. It really gives the VR the acceleration the cubic capacity implies.

That lot will make for a fast road car. If you want to get serious, fit a supercharger. You won't believe how quick it is then.

I have all of the above on mine and there isn't much on the road my car can't take out. It makes Civic Type Rs look like daft :-)

Get you wallet out and start tuning!

i have a 2.8 vr6 obd2, could i still achieve the same final drive (3.68) by using the one from a g60 or does this only apply to corrado's?
