4 branch manifold.

Hey.

Does anyone have a 4 branch manifold on their 1.8 8v? Ive been offered one and wonder if they are better than the standard one?

Cheers

Well it removes those 'orrible c clamps, so that's 1 positive straight away!

That's very true. Never thought about that.

I've got one on mine, I've got a standard engine so I didn't see a noticeable power increase, but I'm sure it would on a ported engine etc.. Got mine of eBay, it needed a bit of force to get it to fit correctly and it still rattles against the gear linkage heat shield at times. I removed the head from mine to fit it as it's a right arsehole to get to some of the bolts. It does sound a bit meaner and if you were planning on tunning your engine I'd go for it. If u go for it i would think about putting a piece of flexi pipe at the front of the mid section.

Thanks for the reply. It's actually a 4-2-1 manifold. Got it yesterday. I'm going with the 2.0 litre bottom end and th 1.8 head. I'm also going to get the head skimmed and port and polish it.

Make sure you get a flexi pipe and consider using poly engine mounts, that way it cannot crack with the movement under acceleration.

Thanks for your advice. Where's best to put the flexi pipe?

i'd put it straight after the manifold. you can get them on ebay or not much money, either weld in or clamp on. just measure the inside and outside diameter of the stub on your manifold and the pipe you're joining it to. hopefully there will be one of suitable size. if not, you'll also need a stepped collar to match the sizes. personally, i'd go for a flex joint that's 6 to 8 inch long.

just be careful if you're putting a 2 litre bottom in that it's not a tall one (like the 2E) as this wil more than likely make your manifold hit the steering rack

Thanks. It's not the taller block 2 litre.

Usually interference with steering or heat shield s is because the manifold is for left hookers. There are loads of European stainless manifolds on evilbay it is best to check they fit RHD or you will need to heat wrap it as they sit so close to the steering knuckle.
