Standard port sizes...

[peteh]

anybody have a clue what the standard sizes are for the inlet and outlet ports on the 1.8 16v head?

Just going to get to the bottom of this engine i have, maybe break it down, as i wana be able to answer peoples questions the best i can

just cause it has verniers on it doesn't mean the cams are a super spec, could just be for show

difficult to tell as the ports are overly large any way and most work is done in the throat seat area so measuring ports is not really going to tell you much but they will be really smooth with a narrow knife edge between ports. don,t really fit verniers for show as you can,t see them once installed in the car.

very true mate, so there's a very good chance that the cams with be hill powers 'own' spec

i was just thinking about taking the inlet off and getting some pics

[MAXIBOY]

think hill power use,s piper or kents. photo,s down the port might show it,s been reworked.

[peteh]

yeah that's what neil (well i think it was him i spoke to ) told me, they develop there own specs with piper

[MAXIBOY]

yes that,s me. depends on application though really.

[peteh]

not looking forward to taking the inlet off though, and it's not even in the car!!!!

how compact are they???!!!!!

there alright i usually use 3/8 and 1/4 kit with flexible extensions. only the last one behind the alternators a real pain
