Manifold identification
So I have in my possession two turbo manifolds that seem to fit my Garrett T3 turbo.

Any idea which is best?

Part number are:

3514275 (came attached to a B230FT)

1366992 (came as a random spare with the B230FT)

I did a search and couldn’t find anything conclusive.

We'll for a turbo redblock everybody like the later 1990 or newer style flows better turbo manifold. Can't see your pics. Anyway the later better style has studs you nut your turbo on with, the earlier style has bolts and nuts.

It seems I may have a 90+ Manifold then!

The picture link should work now, thanks though!

Better flowing manifold is on the right in your picture. Stamped 3514275.

Then you port the opening for the turbo on the manifold to better match the inlet to the turbo. Now you have even more flow with less heat built up in the manifold which will help avoid cracking. Use a standard T3 gasket as the template to open up the manifold.

Use the manifold with no cracks.

The one with the bars between the head ports is better, less warping.

Port match it for more flow.
