pull your injectors and have them modified to run 850cc (ish) and upgrade fuel pump. Get a tune and your all set. That is about as basic as I can be with the limited information you have posted. Use the "search forums" tab and you will find more.
So where are you at with your car modding? Tell us more. Stage 2 yet? If not do that first. I'm pretty sure NF (see vendor listing) can mod your injectors among other things. Minimum you'll want a fuel pump upgrade alongf with injectors and I think you'll want to replace the fuel filter.
Oh yeah, you can avoid downtime and pick up a set of injectors to get modded before tearing apart the car. PM me if you are interested in going that route. Too bad Witchhunter doesn't sell the match sets any more.
