Picture just sent to me via PM. This is a 92 PA Ultra. I'm going to say this manifold was replaced at some point, as it appears to be a 2302, and a 92 should not have had it from the factory. The 2302 part number likely saw first production for the 94 model year.

If you buy a new manifold today for a 92-95, you will get a 2302, but it should not have had it from the factory.

Not shure if you need '95'* still but;

P/N 24502302

Buld date: 7/94

95 SSEi
8/94 Build Date
24502302 LIM P/N

Initial research and final testing will show that manifold #24502104 is the ideal candidate for performance before and after porting. I've got a couple more things to check first, but that'* the way it looks right now.

We need to figure out WHEN that manifold was replaced by the 2302. Can we have the 93 and 94 L67 owners post the part numbers again with the build date of their car from the driver'* door jamb?

So we all know
i am
06/93
and I had the 94 Mani

10/92 here. Early production. I had the '93' manifold.

I am very sure that some parts in my engine got changed before I owned it. When I got the supercharger off, it was very noticeable that the gaskett was not mounted correctly. So someone went in there to change something, and it wasn't the coupler (after 143,000 miles still had the stock!).

And, unfortunatly, the reportedly 93 LIM I bought a year ago, is 24502302.

John, that may be mid-production for 93. I'll get into more detail sometime this weekend why the 2302 intake is a poor candidate for porting and such. I have one more flow test to do first.

I recieved my LIM today at work, its identical to yours Bill, im good to go.
Ran it through the Vulcan four times, and cleaned it all REALLY well.
