On that front brake setup did you have to get custom brackets made or are there vendors that supply them.
The big brake brackets are from 'DeltaV' in Australia.

Nice car! That's a cool wide angle interior shot.
Thanks...I didn't take any of the decent photos myself. The dodgier photos are generally taken by me with my phone haha.

It is SO much fun to drive! The overall driveability is great, especially since I replaced the stock struts and hard springs with the KW V3 coilovers, and got awesome tyres all round.

Like the set-up. You did the A2W a bit different which is nice to see. Massive turbo.
jim
Yeah one of my motivations for the A2W setup (particularly the heat exchangers) was simply to make it unique. I knew it would never beat a front mount heat exchanger, but I thought it would still be comparable.

*EDIT*
I have recently decided to change the A2W setup. I'll be removing the heat exchangers from the engine bay and fitting a bigger one at the front of the car, which I should have done the first time around! I'll remove the barrel from the boot too, and replace it with a FrozenBoost core in the engine bay.

I was meaning to ask, is this the best place for this thread, or should it be moved to show n shine? I assume only the mods can move it...IF show n shine is a better place for this thread, can one of the mods please move it for me, and delete this post at the same time?

Thanks, I knew I should have made a thread on here sooner! :p

*EDIT* the W2A barrel will soon be removed from the boot and replaced with a FrozenBoost core in the engine bay, and I'll be changing to a RacerX side-feed intake manifold/plenum at the same time.

Here are some more photos that may be of interest...

Engine before it went back in the car (previous round of mods), and before the Full Race manifold got ceramic coated in black (I nearly left it bare, but I know it wouldn't have stayed that nice colour for long):

Cam cover which I painted using satin black VHT paint:
