you can piece together a kit for under $3k. Harderst thing to get will be the manifold and injectors. They're high impedence, but it's easy to source them from other vehicles, and with some mods they'll fit. RX7 injectors are probably the most popular as far as that goes. Manifolds on the other hand are a little more of a trick. Mine was actually a modified factory 1.5 exhaust manifold that was restrictive as hell. Easily another 10-15whp if you spend some money and have something custom made that's actually meant for a turbo application. I will warn you though, the turbo will be rough on the valves springs. The 4g15 is notorious for having valve noise after about 85k miles, and the turbo will only accelerate the issue. Not a big thing on NA motors, it'll go away once the motor warms up. But when you're boosting, the valves can tick continuously. When you go turbo, go through RPW and get a set of their valve springs just to be safe. Also be sure to upgrade your clutch. I had a stage 3 clutchmasters in mine, and while it took some getting used to, once you've got it down, it'll really help on hard take offs.
