i have begun porting my friend's 13b-RE irons. got them all marked up and ready to begin cutting on them.


first pic looks kinda weird from the angle of the light, but you can see the size of the stock RE ports VS the medium-large streetport size colored in black.

they are getting widened and lengthened. the primaries need a little more work because these things have pretty big secondary ports stock (and huge runners) and pretty small primaries.

the porting templates are KAHREN "stage1"
sorry the lighting looks a little weird on the first pic





i'll post more pics over the next couple days.

 

I made a paperboard cutout of RE and REW ports, on both the secondairies and int. The Secondairy port openings are identicle to rew ports, (location, size, shape, every way). The RE runners are much larger.

The re int port oppenings are smaller in every dimention compared to rew ports, they are also shapped differently, but the runners are again much larger.

 

yea i really just noticed the size of the runners (they are huge!) and the small size of the primary ports

 

The secondary port looks like my own. The primary is too big IMHO. U'll damage the wall.

 

Are those the same ports you will be doing for me when i have the engine ready?
