The intake hose attached to the throttle body was splitting and I fancied replacing this with silicone pipe and also replacing the resonator box.
The pipe needs to have a 15mm connection for the crank case breather, and looking on ebay I found one of these: http://cgi.ebay.co.uk/ws/eBayISAPI.d...m=320357172701
(its nicely made, the welds are tidy and the inside is quite smooth. They made a half hearted effort at polishing it..)
Also bought a 76mm ID 45 degree elbow with 150mm legs.
As a rough guide I cut 35mm off the throttle leg and 50mm off the other end.
The breather pipe is *just* long enough to reach, though I think a longer bit of 15mm ID silicone hose and some decent hose clips would be better.
The throttle body on this seems just over 70mm but under 76mm, so the 76mm hose is a little loose but with a decent hose clip it feels tight and immovable.
If I was replacing all the hose to the MAF I would go for 70mm all the way, but it leaves the temperature sender..
Havent had a chance to drive it yet, and it doesnt seem much louder stationary, though it seems to have developed a nice bark when it first fires
