Ok, I forgot to mention it already has a boost gauge.
Have been to TruTrack and will be getting some suspension mods. Getting Koni adjustables front and rear. Will use the stock springs as they seem to be pretty good (and I don't want to lower the car at all). All the bushes are pretty much stuffed so Nolathene bushes all round. Also need to replace the rack (ouch).
I'm getting the exhaust done tomorrow. Nothing flash at this stage, just a straight through 3" from the turbo back. $550 from my local exhaust shop (using pipe and pre-made mandrel bends.
Things are getting out of hand, the wheels are stuffed so they failed RWC. So new 17's are needed. This has affected my budget. Hence the cheap exhaust as an interim measure.
After all this I reckon the car will be running sweet.
