Anyone see a problem with this? AAZ to Vanagon.

[Baxter]

Okay,
I do quite a few AAZ to Vanagon conversions.
The way I do mine is to use most of the parts of the 1.6TD (JX) including the exhaust manifold and turbo.
I do it this way to save making bits of exhaust and the K14 is well suited to the engine and the van IMHO.

Couple of things.
the AAZ is 20mm-ish taller than the 1.6 so the oil return from the turbo is too short.
The bracket from the block to the turbo is short.
Now, my idea is to make a small adapter (15-20mm) that sits between the manifold and turbo, this will help me in 3 ways,

1. 1.6TD return line should now fit.
2. Turbo support bracket should now fit.
3. the extra space will allow drilling and tapping to suit EGT probe without having to drill the turbo or manifold.

Can anyone see any problem mounting the turbo 15-20mm further away that it is meant to?



Thats the sort of thing I was dreaming of doing, then drilling through for thermocouple.

Also, anyone know the right grade for the bolts as I will obviously need to supply longer bolts to suit.

Other then putting stress on the bolts to break as long as you have another mount on the turbo it should be fine. I always liked stainless bolts...that way they dont get corroded in.


But thats just me.

I think it's a brilliant idea :idea:

I run a similar adapter from my exhaust manifold to my turbo. But I have a straight piece of pipe between 2 flanges.

I don't see any problems with using a spacer, 2cm won't make any diff in exhaust flow and won't add much stress on the manifold.
