Mounting air deflectors on a 3.5 engine
 

I am building a 3.5 engine using a 3.2 case and 964 cylinders.
I would like to know how to mount the 964 air deflectors since there is no stud on the 3.2 engine case to screw in the air deflectors.
I cannot use the 3.0 air deflectors since they are too short for the 100 mm cylinder

Have a browse through the pics in my build thread (below)....there are a few photos in there showing my tinware....are these the same as yours?

somehow I cannot access your web page

? Seems to be working for me?

How do you do that?
Headstud spacing isn't the same.

I am about to do the same thing. You have to machine the spacing to match. Also, I'll machine the outside of the cylinders in, and the case spigots out to meet in "the middle".
Some more modifications are necessary too, as you'd expect.

I also wonder about this question?
Can I just extend the ones I have for a 3.2 liter? (If I'll manage to do that somehow)

And the heads I guess.
Sounds expensive, why just not sell the 3.2 and buy a 3.6?

Because I allready have my engine to pieces for a quick rebuild, and got the cylinders cheap.
And for the heck of it, I guess..!? :)

But we are not the first ones doing this, I'm sure.

Anyone got some info on this?

We did quite a few of these back in the 90s.
The stud holes in the cylinders can be slotted, the spigots turned down, the case bored and the cylinders shimmed. We used modified 3.3 turbo (78-89) cooling tin slightly modified.
It worked but we wouldn't do it again.

Thanks for that helpful input.

Nice to get some experience input on this... :)

And I've got some more questions:

Cylinders shimmed? Why? to get more deck height? Or for sealing purposes?
Guess you machined the heads as well for clearance?

Why wouldn't you do this today?
-Too much labour involved? Trouble with leaks?

3.6 liter cylinders are about .280" shorter the 2.0-3.2 liter cylinders.
I think I have shims if you need them.
Too many compromises. These engine are difficult enough to build and keep running when you do a conventional build.

Thanks!

Well this changes everything for me.
I have read about others doing this job, but never read anything about the shims.
I therefore assumed they were the same height.

I feel now, like you say, there are too many compromises here to really make it worth trying.

Oh well... At least I haven't started macineing any parts yet. Guess I'll go for a 3.6 liter engine instead.
