quick question
whats the difference in heads? does the turbo head flow better or have different type valvetrain?

**Keeloh** · 11-15-09, 2:01

Only 1 diffrence between n/a or turbo, the exhaust valves. Diffrent material.

ok, so if i were to swap heads for one with lower milage i would have to get one from the turbo model or is the na head just as good?

would it cause failure? or anything crazy under 15lbs of boost?

**Keeloh** · 11-15-09, 3:26

n/a is as good as a turbo head. I have a n/a head on a turbo block, with no problems.

I'm probably preaching to the choir, and everyone knows this, but just in case...

It needs to be an NA head from the cars. The NA from the mazda trucks are only 8v. Again, you prob. knew this, but I'd hate to see someone waste money on the wrong part.

huh? lol.

n/a f2 2.2 head is a 12v. just like the the f2t. and like everyone has said. its the same head, and even cam. only difference is the exhaust valves are made of a harder material.

the valves on the na head are stronger?

No, he meant to say the exhaust valves on the turbo head are stronger, but for most people the difference is negligible; I've run both in the same head with no noticeable difference.

the F2 in the Mazda B2200 has an 8v head.

the F2 in the cars has 12v just to clear that up.

I have a good head if you need one, its from a GT mx6. It just needs to be cleaned up a little.

WHAT!? That's awesome! Thanks guys. I've been a dummy and complete ignored anything with relation to the n/a because I thought it shared the B2200 head. There are TONNES of these cars around at the wreckers in n/a form. Gonna have to go grab one now I think.

**DarkMx-6** · 11-22-09, 17:30

Are you thinkin of grabing a 12v head and putting it on your truck because its not that easy.
