deng, 20 with a 2.0L? i get about 28-30 MPG in my 1.8T...thats crazy. as for the other stuff, i would rock out with a turbo. it really depends on what you want. the turbo will give you a more sporty feel vs. the SC feeling more smooth. the turbo can be more tunable, upgradable, and modded. as for the supercharger, you will be running about the power you would in a VR6 with maybe intake and exhaust if that. the only upgrades you can really do on a SC is a lighter smaller pulley, exhaust, intake, maybe megasquirt...theres not much to it, depends on where you want to go.
then you'd be reaching peak, and only getting around the level of a 1.8t, do the swap man, actually it would probably be easier/cheaper to trade upto a GLX or something... that what i'd do, then mod thatWhat do you guys think about the EIP tuning stage 2 kit? Moves whp from ~93 to >155. I'd also toss in a cold air intake and high-flow cat (or busted out cat) and try and find a non-ricey exhaust.

Would the $500 more stage 2 kit be worth the extra cash?
I'd probably also add upper and lower stiffiening bars because what's powoer if you can't speed around bends... Also probably sport suspension...
All of this is provided he can get the kit through school.
GET COILOVERS! Don't go cheap on your car. Don't get springs or chop the springs. GET CO's!!!man, lowering your car will be the best thing you ever did. i loved my old 2.0, i acually miss it quite a bit over the new 1.8T. it was lowered 2.5 inchesF and 1.75 rear...there was less than a fingers gap. lower it, you will be happy, add on an exhaust system, and a CAI. then from there, you can decide wether you want to turbo/SC it or not. i was going to do a SC, cuz its easier to maintain, just slap it on and go, the turbo needs tuning and such. if you got any questions im sure i can try and help you. also check out the vwvortex.com forums if you havent, oodles of info.
