Upgrading the Manifold on a Cab

[Phil303]

Hi all,

Has anyone with a Mk1 Cabrio (1800 carb) upgraded their manifold at all? I want a bit of extra ooomph (technical term) but not at the expense of potentially ruining an old but essentially rock solid and reliable engine.

A mate suggested changing the manifold and/or air filter. Has anyone got any advice or recommendations?

Cheers guys.

Phil

Phil, PM richandhazel in case he doesn't see this thread as he's up on changing the manifolds.

I've got a very restrictive 4 into 1 exhaust manifold on my cabrio. I have managed to buy an older 4 into 2 (similar to the mk2) manifold which is supposed to be a lot less restrictive. Haven't got round to fitting it yet but will do very soon. I decided to go that route instead of a stainless branch manifold as I've heard lots of complaints about them cracking. There was a very good article about it in Golf+ not so long ago. I'll try and find it later on and scan it in for you.
