Hi Everyone,

Just wanting to know if anyone can help.??

Will the standard A12 exhaust manifold be ok to use on A14 head?

I am currnetly running an A14 and my manifold is really badly rusted and corroded and can get hold of a 120y one. Will there be a major difference eg in port size etc.. bolt patterns?

Any advice would be very handy.

Thanks in advance.

Kieran

no, have at look at this picture. the a13 is same as a13/14/15.

Hi Kieran...

Although I can't speak from direct experience, just from reading other posts on the matter I'd say not as the port shapes are different (A12=round and A14=oval) plus there are water jacket holes to contect with as well. Finally, the A12 has a 2 bolt exhaust flange and the 14 is 3 bolt.

But I'm more than willing to be corrected on this by anyone so if I AM wrong, mea culpa.

Hey Guys,

Thanks for the prompt responses..

Looks like i'll have to keep looking fo an A14 manifold.

Cheers heaps!

he is talking about the EXHAUST manifold, im pretty sure those 2 replies were talking about the INLET, the exhaust should be the same, just be careful the base of the inlet manifold doesnt foul on the exhaust as happend to a mate of mines (caused air leak on inlet, between head and manifold) we just had to file the inlet manifold slightly so the two manifolds didnt touch

i would think your exhaust would still be ok if it is only rusted on the outside, inside is usually not, usual full of carbon

but on the outside they all are, so unless it looks like its gonna fall apart i wouldnt be too concerned with reusing it, thats unless you want it too look good too

edit: the port sizes are the same and in the same location (square shaped) and the bolt patterns are the same, thats why i think only fouling with the inlet manifold could be a problem

as far as i no the later a12 such as the120ys and later model 1200 utes used a manifold with out a manifold heat box . but thats just going by what waz on my ute

Hey Dattopower, don't know if this will be helpful or not. Would a 140J have the exhaust manifold you need? Try Pick-a-part in Avondale! I got the carpet out of the one they had there some weeks back.
I had to get an exhaust manifold for my 120Y in time for it's WOF last month. I got one through Eden Park Car Spares in Sandringham. $45. You could try there if you have no luck.

get a new space bar; they rip

I know i have an a12 set and I might have an a14 somewhere you can have if you want, pm me.
