my personal opinion would be to get some UR 600cc injectors, fp td05h-18g turbo, and a tuneable form of EM (utec,aem). This way when the power doesn't impress you anymore down the road, you've got more on tap, plus you have an em that you can easily adjust with more upgrades/tune for racegas etc. Buy this setup than save up for some RA gears/tranny upgrade and turn the boost up more often.
