Chrissi,

    Can the manifold connection to the block be reversed - Will

fit such

that the exit pipe points toward to front cover rather than the

flywheel?

My stock 91 can be switched that way and I am curious as whether

this one

can also be switched.

Thanks

Ed,

I also have the stock '91 be it cannot be reversed without

re-drilling

the mounting holes as they are not symmetric.  also remember that if you
reverse it, then it places the turbo much lower and you will then need a
return oil pump.

Dave,

    As best I recall the turbo can not be reversed for the reason you
stated, however, the entire turbo exhaust manifold on my J 91 can be
reversed and once a small bit is ground off one of the exhaust flange to
make room for the tension bolt, it can be place on the block in reverse.
So, if you manifold won't must be different from the one I got on my 91.

Ed Anderson

Are we both talking about the manifold on the left?

Paul Lamar

The one on the left is same as the one I took off the 91 turbo. If you pick
it up and reverse it, it will sit down over the block manifold studs - but
the outer edge of the exhaust flange ( the side toward you in the photo
which are more "pointed" than the opposite side) will need a little bit
(around 1/32") ground off so it will not hit the tension bolt that runs
beside the manifold. On one of the blocks I have that it would not do so,
but it turned out the exhaust manifold studs were bent out of alignment.
