Aren't the 3.4 exhaust manifolds interchangable with the 3.0. I, can't remember if they will work on the 3.0?


Anyone?

 

it appears they do....i got hte urge to check AFTER i remounted the 3vz-e heads back on the engine...i got some pcitures tho so once i get them off my camera i can see.

 

Pics would be GReat, if you could post or email them I, would apreciate it.

How well do they line up with the ports and the studs, any problems mounting?

 

ill find out shortly

 

Bookmarked!!! lol

 

If the 3.4 exhaust manifolds will work on the 3.0, let me know because I think I will blow my load. They are a much improved design over the 3.0.

 

A friend who is a Toyota mechanic tried the 3.4 exhaust on the 3.0 and it would not fit. That would have solved a lot of problems if it would have worked.

 

did he say what didnt match up?

 

I, didn't get into specifics with him he was in a hurry. Did you try it yet?

 

i didnt get a chance to try cause i put htem on the truck without testing them i forgot...i have 7 car/trucks lined up here for big work so i totaly forgot...i got pictures tho so ill see how they match up

 

5vze manifolds wont work on a 3vz-e heads vise-versa. The 5vzfe have off set bolt pattern while the 3vz-e manifolds have a verticle pattern.

 

Sorry to revive this old thread. Has anyone tried modifying 3.4 headers to fit a 3.0? If the ports line up could you just re-drill the flanges or something? 3.4 headers are just easier and cheaper to find so it'd be cool to be able to adapt them.

EDIT: What about 3.4 heads onto a 3.0 block? Maybe possible cause you can drop a 20R head on a 22R block, so maybe they keep the heads similar in the V6 family.
