Rossco 0 Posted June 11, 2003 Right i have recently bought a mk2 golf 16 valve inlet manifold to replace the one on my corrado cos of the whole 50mm thing(not gonna bore you wi it) any way i sent it off to get powder coated and i got it back yesterday and i've gotta say these boys did a brilliant job. Anyway i'm gonna change it some time next week and apart from changing the injector seals and the gaskets should i change anything else. Ps any advice from people who have done this before would be greatly appreciated. cheers Ross Quote Share this post Link to post Share on other sites

fry 0 Posted June 11, 2003 Hi, I got one on my 16v problem is it made no noticeable difference, I have a 1.8, running a k and n panel filter and I drilled the airbox. I suddenly wish I had bought a g60 - :? Quote Share this post Link to post Share on other sites
Kevin Bacon 5 Posted June 11, 2003 The 50mm manifold should give more pull at the top end, but at the slight expense of bottom end. Swapping the manifolds works on some engines and has no change on others, it's a 'suck it and see' thing. A full manifold overhaul includes the following:- 4 x brass injector seats 4 x brass injector seat seals (black) 4 x Orange/brown plastic injector guide tubes 4 x lower injector seals (black graphite coated) 4 x upper injector seals (green) The whole lot comes to about £50 and gives a really nice idle.

You also need the long 4 hole gasket that joins this to the 'banana' bunch. Another thing I've found that helps with valvers is to run an earth strap from the inlet manifold to direct to the battery negative terminal. I used to use those black cables that Halfords sell by the batteries. Secure it to the manifold under one of the 13mm nuts. Cheers Kev Quote Share this post Link to post Share on other sites
