Well the previous owner was ahead of you all cause when i got my starion it came with a cold air intake made of PVC piping and the top of a coke bottle acting as the reducer into the standard intake pipe
Tested out my PVC inlet pipe today. No worries doesnt even look like getting hot. Now cookie about that exhaust, I have some 100mm stormwater pipe left over from work.
I wouldnt want to belong to any club that would have me as a member
LOL the pvc pipe and coke bottle came out already, meh i would prefer metal pipe between the turbo and airbox and then aero style steel ribbed rubber tubing, works the treat and stays the same diameter all the way through, cost is like $6 a foot though, me raids the store room
speaking of nitro it is injected at roughly -110 to -120 degC and so greatly reduces charge air temp upto 50 to 60 degC in most cases. BUT.... nitro fuck's your engine.... interesting situation.... :-)
