Stzrt by looking in the rb20 sticky section at the top of the page, anything up to about 250rwkw is about the limit of streetable power, although at this level expect it to be quite laggy. I believe the gearboxes are similar to gtr ones, so you wont have any problems there. Depending on what power output you are after, look at the rb20 guide, there is heaps of turbo selections avail, you just have to weigh up lag versus power. There are two guys on here who can do chips, no where near $1000, lot cheaper, or you could get a power fc for about $1600. You will need injectors, gtr ones are cheap and go straight in, a gtr fuel pump will do nicely, cams and gears aren't a bad idea, but ive seen 276rwkw without them. Use the search function it will save you a lot of time. The biggest problem you will have is that it is only a 2lt, and to make big power, you get big lag.
