yes its worth it - Turns the VR from a nice, but average, car into a beast! If you're talking about a stage 1 kit the only thing you'll need to change (depending on the condition of your engine) is exhaust... you'll benefit from having a bigger bore than standard and losing the cat. Might want to think about engine mounts and a mocal oil cooler as well... Your car looks like an early one so might be worth uprating from the 280mm brakes to the 312mm TT/S3/4motion set up. Cant remember what stage 1 makes? about 270bhp I think but theres lots of people on here with vortech chargers
