mines a 1.6 so only did all the coolant pipes. when cool just undo the pipes and best use new clips, you will lose a tiny amount of coolant so just have some to hand. hope thats what your looking for

Yeh, there was a thread on here, which i cant seem to find anymore :/ that said about replacing the 8mm vacuum hoses

i take it there not 8mm then :/
4/5mm is for the vacuum lines, dump valve type of size, depends what lines you are actually replacing?

An old pic but you can see the larger ones are 8mm
DSC00124.jpg

They are
1. Top of throttle body to check valve
2 Check valve to solid pipe against bulkhead
3. N75 to port on charge pipe next to DV take off ( blanked off on mine)
4. Carbon canister to hardpipes aginst bulkhead
5. Expansion tank to hardpipes against bulkhead (coolant)
6. N75 to actuator but needs to have a reducer down to 5/6mm for actuator fitment

4mm ones are:

1. Under inlet manifold to FPR
2. Under inlet manifold to N249
3. N249 to top of DV
4. Boost gauge piping (FPR is adviseable place to tee for source)

Good list Ronin, I've been looking for something like that for a while. Quick question tho, I see from that photo that you haven't done the pipe running from the driver's side end of the intake mani in a horseshoe shape, round the charge pipe to SMIC hose - would you happen to know what ID that pipe is?

I'm suspecting it's 8mm but wondered if the reason you hadn't done that one was cos you'd tried 8mm and it didn't fit...

Ok so silly question as im too lazy to check, does anyone know the OD of said pipes? Ill order up a box load of Mikalor clamps and thinking that a box of:

8-16mm x 10 pcs
16-27mm x 10 pcs

Should do me pretty nicely for my entire pcv system / catch can, and all parts on the TIP. + spares :)

Ronin, have you done this one? If so, can I ask where you got an 8mm -> 5/6mm reducer and joiner from, if that's how you did it?

Didnt replace in the end but will do at some point
The wall of the pipe does seem thicker on this though
