What exhaust manifolds fit the 14NV (1.4L carb) engine?

[AndysMK3Cav]

Hi

At the moment I have a standard exhaust manifold on my 1.4L Cav, it is the carburettor model which I think has the engine code of 14NV (is that right?). Would manifolds from other Vauxhall engines fit it? I'd like to fit a 4-2-1 style manifold for a bit more pep Am I right in thinking the engine is my Cav is the same as the one in a 1.4L Nova? Would a Nova 1.4 SRI be a potential source of a better flowing manifold?

How about this manifold for sale on this forum? viewtopic.php?p=140137#p140137

Apologies for the novice questions

In my opinion, trying to increase power from a 1400cc engine in a large car is a bit like trying to make a gerbil run faster... Not gonna happen I doubt a manifold will help, maybe tweaking/cleaning the carb and a sports panel filter may help a little, but you won't see much improvement in the long run.

The 1.4 is the small block engine so I doubt any C20NE/20SEH/C20XE (big block) exhausts will fit.

If you seriously want more power but don't want to do an engine swap, look into getting a bigger carburettor.

If you are prepared to spend the money, then I think a custom exhaust is the only way to go really.

I'm looking at getting a Weber 32/34 to replace the Pierburg carb

I like the idea of doing something different than an engine swap and am already pleasantly surprised at how my Cav performs all things considered. I'd just a little bit more Plus you don't see many 1.4 Cavs about.

Having said that there's a Nova in a nearby breakers and looking at the pictures it has a redtop in it and various other performance orientated items fitted (induction kit, exhaust etc.). Also a big 'Seized By Police' sticker on it

Forget tuning a 1.4, if you don't want to change it the best way to improve the performance will be to reduce the weight it is carrying.

You're right, I do need to diet
