I was just checking out mazdatrix web site trying to figure out what gasket I should order for my 4 port 13B. I'm using 12A irons with rotors and housings from a GSL-SE. Any ideas?


Thanks, Ed

 

it doesnt matter, only real difference is the intake gasket

 

Get the atkins 12a gasket kit and a intake 4 port and exhaust gasket and your good. 12a gasket kit from atkins was 109.00. That's what i did..

 

I have an old style 4 port 13B gasket. I can't remember if I got it from Racing Beat or Mazdatrix. It was one of them. They didn't have it listed on their website so you'll have to call them to order it.

 

This has gone up in price a bit. http://www.mazdatrix.com/getprice.as...m=99-100D-3565

 

Thanks for the response guys. I just priced mazdatrixs 12a gasket set at $102 + $7 for the intake + $12 for the exhaust with a total of $121.



Thanks, Ed

 

The oil pan gasket is not going to fit, but there are a lot of guys that don't use an oil pan gasket. Just thought that I would throw that out there to make sure that you knew.

 

On a side note on somewhat the same topioc. Does anyone know how you can tell the difference between a 74-75 13b and a 76-78 13b? I need to rebuild my engine and the gasket and o-ring kits are different for the two engines, but I don't know which one mine is(it came with the car when I bought it).

 

I kinda doubt that. I've used the gasket set I've mentioned above on both my R5 13Bs which are a bit newer than '74. Infact with the nitrided side plates, I'd say they're '79+.
