Double check with Mudski as I got all the NADS stuff from him, from memory.
The catch can was $100, had to spend another $30 for the hoses, fittings and clamps, I used proper hydraulic line so it cost me a little more.
Dawes and needle valve with EGT plate was $145
The pillar pod was $159 delivered from eBay.
The gauges are SAAS and came in around $200 for the both of them, got them a little cheaper as the guys at the place I shop look after me on prices.

Really worth doing, I inherited this car from my missus about 4 or 5 weeks ago via a family swap out/hand me down, funny how she got a new car
She drove it the other day and couldn't believe the difference in the response from when she had it.
