The best idea would be to buy quality parts, sepereate from the kit. Although it can be slightly more expensive, you'll thank yourself in the long run.

You can piece a _good_ kit together for around 2500 bucks, and only get the stuff you need.

You do not need: FMU, Blue box, SAFC, MSD ANYTHING.

You do need: Larger injectors to meet your power goals, Engine Management such as uberdata, you will need a competent tuner, a fuel pump would be a good idea, however unnecessery unless your planning on running more then 350whp.

A good manifold will run you 500 bucks at least. A downpipe can be custom made, expect to pay 300 for one. Maybe more. 2.5" is the least I would go with a downpipe.
For decent power at low boost, go with a decent sized t3/t4 or other proven hybrid turbo. At least a .63 a/r stage 5 exhaust wheel.

For intercooler, I would recomment at least 3" deep, 8" high, and 24+" long. Keep the piping as short as you possibly can. The size of the pipe should be kept 2.5"+.
oil lines and small fittings should be purchased at Amazon hose. They are resonably priced, and have everything you need as far as couplers, clamps, and hoses.

There are many shops around here competant enough to tune uberdata. However from what I've personally seen. I would have to go with Dave for your tuning. 99B16SI. He's an intelligent little man, and he hasn't been in the game so long he's burnt out. So he still has his heart in the cars he tunes.
