If you're going to boost it, I say go turbo. You will make more power in the long run for less money and you won't have belt slip to constantly fight.
No doubt man. Everytime i change out pulleys I have to adjust the tensioner pulley to get it just right. I would say 1 boost run in 10 I get a little built slip but its not too bad.
As was stated before if your looking for a kit to buy then supercharger is your route...
If your like me and just have to have a turbo it's going to cost LOTS of mula...everything pretty much has to be done custom. Here's a link to what I am doing:
sd-concepts.com just got done fabbing and installing a front mount twin turbo kit. I believe all the parts headers and all start @ around $5200, and can go up from there depending on turbo upgrades, waste gates, bov's, injectors and fuel system.
Krc also offers a twin turbo rear mount set up for around $3500 I believe, and that is with injectos, and tuning in the price.
My single rear turbo from krc is up and running as of yesterday, should have some dyno videos this week
