thanks for the comments guys

willp, i am as shocked as you mate, went in expecting much lower numbers than that!!! as you say just imagine s300 some goodies and a good tune

i am unsure of the diameter of the skunk intake hole on the manifold, may be on the website i will have a look, but its running the stock c4 throttle body at the moment thinking of giving it a polish, knife edge the butterfly and port match to the skunk.

thinking of keeping my c4 exhaust manifold too, but doing some porting work on it were it joins the head as the welds are lumpy and protrude into the port.

dose anyone know if there is any good ceramic coating available on the market that you can apply yourself or would it be best to send it out to be done

If the skunk2 inlet hasn't been machined then the hole is 64mm



The max you can machine these out to is 75mm

Ah right... the information on these is a little misleading... cos some say upto 75mm but that provided you machine them out!...

So its only the type r with 62 inlet... so in order the fit a larger TB to any of these manifolds they would need machining??

Give Marcote Ltd a ring in Lichfield http://www.marcote.co.uk/

Marks the man in the know...

they specialize in coatings of all descriptions. Teflon based non stick may be better if you will be on the colder side of the engine i.e intakes. Ceramic can be applied or zircon based may be better which takes temperatures of 1725 deg c on exhausts.

Which size are you needing? the one for the TB or for the inlet?

The standard b16a2 TB is 60mm and the standard b16a2 inlet is 62mm, not sure on the c4 inlet but yeah the c6 TB is 62mm so the inlet must be the same as the skunk2 at 64mm

If your machining out the standard TB then you would need to check the max you can go, I know on the inlet side of things with the skunk2 you can't pass 75mm, not that in an ideal world for a road car you would need to machine out this big........

I'm using a 68mm TB and my skunk2 inlet has been machined out to 68.5mm, so whatever you choose make sure the inlet side has 0.5 or 1mm larger than your TB

Handy little reference
