92-93 engine differences - ZR-1 Net Registry Forums

Subfixer · 12-10-2018

I need a oil pan gasket and was surprised to see they are different between 92 and 93 on Jerry's Gaskets website.
I ordered one for my 92, but being a fairly late 92 (#442), I'm hoping its the correct one.
Any data on the differences?
Thanks

You should be good. 93 was the first year of the 405hp 4 bolt main bearing engine with a multitude of upgrades over the original 90-92 375hp engine. I’ve never heard of a “running change” type transition for this engine update. It was a hard “model year” changeover.

This will give you a better idea.

My motor was in 92 #454 and it was fine using Early version gaskets.

Looks like I ordered the correct gasket.
