all good suggestions, and may I add 1?
get a good adjustable fuel pressure regulator. The stock 1g 5spd has 2 knocks against it. One, its pretty low pressure at like 36 or 38 psi, whereas all the other turbo DSM's are in the mid 40's. And 2, it can't flow enough back to the tank, so it has issues with big pumps like the 255 Walbro's and the Supra TT pump.
You can get a real nice one from
www.fullthrottlespeed.com Cost is $145 US, plus border crap. There are others, but you have to rig em up. They are cheaper tho. I am in the process of deciding, because I am pretty broke. If you can afford it, get the good one. It will help you to tune in the future, and thereby make more power, get better mileage, pass aircare, and have a nicer car to drive.
