thanks guys.
Yeah Guy I will have to polish the intercooler - am probably going to paint the top of the intercooler and mounting brackets black, and the top of the oil cooler as well. Might find some R34 style black mesh and put it back there too.
Pete - yeah the fit is not perfect, but I just quickly trial fitted the bar the this stage, so will massage it a bit more and make it fit better when I take it off to paint it. Hopefully I have a vented real carbon fibre bonnet and boot to come shortly that will complete the look (speaking to a source in China as we speak). Then I have to decide whether to respray the car Obsidian Black again, or go Midnight Purple (which was my original intent). Unfortunately Midnight Purple 3 (the harlequin colour that came on R34GTRs) costs $1k a litre and I would need just under 3 litres to paint the car, so it would double my repainting cost - so might go with Midnight Purple 1 of R33GTR fame.
