Hi,

Just yesterday I got a full fairly new exhaust system for my KE15. All the system fits APART from the exhaust mani that bolts to the head.

 

After stripping it back today to bare metal and painting it I noticed the heat exchanger box on the KE10 mani has the 2 bolts towards the cylinder head and the single bolt towards the wheel side of the car. And this manifold is off AE70's KE10 so it is an original manifold. So did some early KE1X manifolds have the heat exchanger box bolt pattern backwards?

 

As Most normal corolla K exhaust manifolds have the single bolt on the cyclinder head side and the 2 other bolts on the wheel side. So in effect the bolt pattern is switched backwards different to other corolla manifolds.

 

This presents a problem to me as my original water cooled twin carby big port manifold off the car has a single bolt for the heat exchanger on the engine side. So it doest fit this KE1X manifold. As the big port intake mani is like normal corolla bolt patterns. BUT it has the smaller KE1X heat exchanger area this prevents me from using any later manifold as the exchanger is to big.

 

So I am curious as to know did the big port manifold have its own unique heat exchanger box pattern?

 

And does anyone have one that will fit (eg single bolt on engine side and the smaller heat exchanger) so I can get my car going finally?

 

Cheers

Also Just a few pictures below so you can all see what I mean.

Above you can see the 2 bolts closest to the cylinder head side on the exhaust mani

Above is the inlet manifold showing the 2 bolts are on the wheel side not closest to the engine.

And above again this shows the inlet manifold has the single bolt closest to the engine side and also in all the above photos you can kind of see how the heat exchanger triangle is smaller.

Are you sure then exhaust manifold is an original item? Not a stuffed up aftermarket?

Was on my Ke10 but I'm not sure ?

Hi,

Manifold is an original item not a stuffed after market part as it has the Toyota part number cast into it and it has the TEQ/old Toyota logo also cast into it.

Yes I have seen these two different bolt patterns, but I have no idea why or which models are different. Personally I have only had the manifold that you have, but have thrown out extractors set up like your exhaust.

just bolt a plate over the hole in ex manifodl to block hole.

ive done it before and had no dramas.

 

cheers scott

don't do it with thin aluminium though, it melts....... :P

HAHAHA don't worry. I got some 1mm thick stainless cut out today I was going to try it with if worse comes to worse. As I am worried with this method the intake mani wont seal properly if it is slightly offset due to bolt heads and I refuse to grind the intake manifold to make it work.

 

But if stainless steel fails me I have some metal sheet that is the same as what some gas turbines hot end turbines are made from in aircraft :P here that is looking for a use so I will try that at last resort.
