B6T to B6ZE head swap

Campbell* · Post by Campbell* » March 1st, 2007, 10:10 pm

Ok first of Iv search and couldn't find any threads that contained info to the b6ze head swap. If there was thread Im sorry but I need to know

I bought a complete B6T swap but I don't want to run a hood scoop and wouldn't mind the extra ponies that come with he N/A head. I hear I can put the b6ze head (I think thats what the N/A DOHC head is called), but I need to plug two oil galleries or somthing in the front. Is their anything else that I need to do to make the head fit the B6T block? Also, what cams do I use, the turbo cams or the N/A?

If you have any info that would be great because Im doing the head swap very shortly.

you have to plug the front oil galleries on the head. then there is another gallery that you have to plug. its near the transmission on the block.

use the n/a cams as the b6t cams WILL NOT work. the duration of the cams is off and it will just be easier to use the n/a cams as they are made for the head. thats all i can remember for now but ill try to remember other stuff and feel free to ask questions since i tried this before.

I think the B6ZE head (engine) came only as a RWD application (Miata) and the DOHC B6DE is what came stock in the 94+ MX-3's. They will bolt onto the block.. but the intake & exaust manifolds are on opposit sides I think.. Or maybe it was an issue with the distributor location.. I am not certain in any case.. but I think there are issues with the B6ZE head. I bet Josh would know for certain. But you should be able to swap to a B6DE head without a problem. Cheers

I used the stock head. I wasnt aware of any gallys that had to be plugged. I got custom cams and used the b6t block and rods...and used my stock crankshaft and weisco pistons.

Why dont you just swap the intake mani's? Be much easyer if u ask me.

This may be a stupid question but where do I get these threaded plugs, the head should be here anyday now and I have all the other parts except the plugs.
