hi james,

i've not long bought a gt4 charge cooler for my rev 2 turbo.

it's the st205 version which is the perfect match for your rev 3.

there is a couple of things that need removing from what i seen when i had a look.

boost pipes to and from intercooler, the intercooler itself too.

on mine some of the throttle body has to be removed but its only 4 bolts.

the hardest part from what everyone else says is removing the front bumper to mount the radiator!!!

the whole installation is meant to be time consuming, allow a day i was told but its well worth the trouble and a good mod for the car.

good points are cooler, denser inlet air allowing more boost and fuelling but keeping the engine safe i think.

i'll be fitting mine over the christmas holidays along with downpipe, manifold safcII and avcr so i'll let you know how i get on.
