Engine/Transmission (1994 - 1998) Would a 24V Exhaust Manifold Be A BOMB on a 12V ?

[DieselMinded]

Will it fit ??



Will it flow better ??



Thanks guys

I dunno, the exhaust ports are different shape, 12 oval/square, 24circular, I doubt that would be a good mix. I think the height of the 12valve port is more than the diameter of the 24valve version.

It would flow worse due to port mismatch.

Ok thanks

I agree. More than anything it would be a big mistake. As much as they crack, why would you want one?

ok so the 24vs crack and the 12vs shrink, great designs guys keep up the good work

Been thinking of upgrading my Exhaust manifold on my 2002 ,,,the BUDGIT BOMBER my brothers 1994 usually gets all my old parts ,,,, Just checking to see if the 24V exhaust manifold would be a benifit to him



Thanks Guys

I don't know about the shrinking, but mine's been on for 334K miles. Looks the same to me.





And if you give your brother the 24V manifold, you and he must not be very close. As a matter of fact, you must not like him very much at all. Why would you do that to him?



. . PT. .

The odd part is that most ISBs in commercial applications use 2 piece manifolds, I don't think I've EVER seen a one piece in anything over 10k GVW

mines been on for 307 and it's a bit short now starting to bend the bolts in on the ends and i have read about many others, even herd about a chunk getting broken out of the head from it

I don't know about the shrinking, but mine's been on for 334K miles. Looks the same to me.

Mine was bent the bolts pretty good with only150k on it. I'm glad it's off there now
