I am going to do exactly the same thing. I am looking to incorporate some metal tubing in the setup and connect it all together with hosing (standard or maybe uprated silicon jobbies). What about scaffold bars or something like that - sounds too cheap (but if you can make a great induction kit out of drain pipes anything is possible) but it may work.
Well if you measure the bots you need and contact Pace then they can make them up for you and also form ridges on the ends to clamp the hoses behind and stop them popping off.... Been there and its no fun
I'm looking to move mine cos i've got the phase 1 kit. Whilst it apparently doesn'y NEED a bigger or better intercooler I think its a good idea to improve any just to be safe. If i go for more power i'll get the 8.1 litre.
