Title: V6 Manifolds Query
Post by: VXL V6 on 08 May 2008, 21:01:33

Question!

Are all V6 Manifolds the same? 2.5, 3.0, 2.6 and 3.2?

TIA

Inlet or exhaust???

Not that I know the answer but I'd be interested to hear it... Especially as I'd like to get a spare inlet manifold for when I do my LPG conversion!

i'm not 100% sure on this....

I have had in my possession at various times a 3.0, 2.5 and 2.6 inlet, each of them had the engine size marked on them, so i wonder if there is some subtle difference

I know the 2.5 and 3.0 exhaust manifolds are the same, have both sides for a v6 sitting in my garage...not sure if facelift is the same or not

The manifolds on the 2.5 and 3.0 will have the additional holes for the Secondary Air Injection, which the ones for the 2.6 and 3.2 won't have.

I'm pretty sure the 2.6 and 3.2 also don't have en EGR valve, which would mean the wiggly pipe connection would not exist on a OS Manifold on these models.
