Give them a tinkle for the pipes, they'll have the intake and boost ones all ready to cut from a reel. Also, they'll be able to answer your questions regarding precautions as I believe the 1.8 8v turbocharger conversion was one of their first!
I dont think Ive got any detailed pictures of that actually - I'm too ashamed of my grubby engine bay <even more so after seeing piccies of Spankee's motor...I digress>.
On mine I've got a fabricated manifold, which joins the head and turbo inlet. The turbo is a tiny hairdryer type T2 <does the job though>. The turbo exhaust outlet then is bolted to a fabricated down pipe to enable the fitment of an off-the-shelf standard exhaust.
As for pipes, the inlet flexi pipe <cacky orange **** from Courtenay> starts at the driver's side, then through the inner wing under the chassis rail and into the turbo. The boost pipe from the turbo exits through a U-bend affair which goes past the radiator to the intercooler. The intercooler exit pipe passes the radiator up towards the inlet manifold as per the normally aspirated inlet.
Dont think I've missed anything pipe wise.
I reckon that unless you've got access to a **** load of pipe sizes you can cut off a reel, or special corner pieces I'd just phone Courtenay for the complete kit, or maybe measurements. It'd be a total pain in the arse to keep ordering from Demon Tweeks to get different lengths of Samco hosing.
Dont forget the turbo will need an oil feed and return. The feed is more often than not <on converted cars this is> taken off at the oil pump pressure switch/sensor assembly. The return is made through a braze-on at the sump and nice fat rubber pipe. which incidentally is a right bastard to get off if too long . Also, your turbo may be water cooled, this will need plumbing into the cooling system appropriately. Although mine isn't so dont have that plumbing, I just have to worry about turbo heat soak after a long run!
