Yep, you have to wonder if this is part of the cause of cat in-efficiency issues!

Should increase the top end, not much lower down as there still not perfect.

But, with the better inlet setup and 3.0 cams plus good stem seals it should run nicely!

Been watching this thread with interest ::). After seeing what a rebuild does to a 4 pot without any mods.

Planning on rebuilding a v6 when I get hold of one.

But with lower compression on the 2.6/3.2 and changing the ancilleries to make up for this. Does that mean a 2.5/3.0 could potentialy have more power if the best bits from both engines were fitted?

I'm confused...

Facelift has different nuts for holding the manifold in place, yet same studs???

Part numbers differ on the nuts...

So its just purely the bolt depth/height which differs then?? As the thread is the same...
