I know that N/A Motors have the Exhaust Insert in the housings and the center housing has some very lame ports on it with no room to open them up, But the 6 ports are offer much more timming that a Turbo or any other product 13B, So wouldn't it be a hot tip to swap 6 port front and rear housings into a Turbo motor? Or vis versa?



You would have the larger Turbo center housing ports with the larger and additional port timming from the 6 port motors plus the elimination of the exhaust inserts.

 

n/a tuners do that.

 

alot of people run turbo rotor housings because of the bigger ports and no stupid sleeves

 

what about running just the turbo intermediate housing? I'm rebuilding my 6 port this week most likely, and I plan on doing a street port, but it looks like the intermediate housing has small ports and water jackets real close, are the turbo intermediate housings interchangeable? if so, got a good one you wanna sell me?

 

six port street port from judge ito

 

Yep, you can do that. That is what I am running with two turbo rotor housings.

Hrm, that sounds like a good idea. Are the turbo housings compatible with my header and 6 port side housings? Will anything need to be modified or plugged?



I just checked with mazdatrix and the 86-88 turbo intermediate housing is $342.46,

and 86-88 turbo rotor housings are $462.49 for each. Kindof expensive, anyone know where I can get these cheaper?

 

I was talking about just replacing the intermediate plate (center) and perhaps turbo housings to get rid of the silencers in the exhaust port.



But the Intermediate housings on a 6 port have VERY small ports.



Here's a good picture:





The 6 ports in the end housings I would keep as they offer additional port timing.

 

according to the mazdatrix site, the turbo rotor housings have a water passage above the exhaust port which needs to be plugged on the N/A if you use the turbo rotor housings.

 

I LIKE MY STUPID SLEEVES!



YOU'RE MAKING FUN OF ME ARN"T YOU!?







I was kicking about the idea of going with a standard 4 port 13B and carbing it to see what kinda power could be squeezed out myself.
