4port 6port?
Just a thought coz I'm in the process of building a 4port 13B but someone suggested that I just use the 12a intermediate and keep the 6port ends and port out the divider on the 5th and 6ports. I personally wanted to build the 4port with a streetport for more power. Would removing the divider and using the 12A mid plate yield about the same result in power as a 4port? Also what intake would I use if I decide to go with just the 12A mid plate? Any thoughts?
Thanks, Ed

Nope, the end and center plates can be swapped between 12a's and 13B's. Watch for where the O ring groves are, the 6port's had the groves on the cast iron plates, the gsl-se and old have them on the rotor housings. I could be alittle of the mark but not by much.

Also I understood that the rate of failure on the 86' and newer center and end plate grooves was much higher than the older 13b 4port and 12a gasket grooves, is that true?

Try to stay away from the NO casting intermediate plates found on Jspec or '80 EGR engines (I can't remember which). I have one of those and its ports are at least as tiny as GSL-SE if not smaller. There are no injector bungs of course. In other words, if it says NO, well, it's pretty self explanatory.

In the intermediate housing, why can't you just grind the tiny ports out until they are as big as the larger ports? Isn't that considered part of "porting"? What am I missing?

Guys, I dont think I made myself clear. I have 12A plates and SE 6port rotors and housings. My question was should I just use the 12A intermediate plate and keep the SE's 6port end plates or just build a 4 port? I'm trying to keep cost down and by going to a 4port I'm going to need a 4port intake for my Dell. Now if I retain the 6port set up but use only the 12A intermediate plate. What intake can I use? Can the SE lower half of the manifold be ported to match the bigger intake ports of the 12A plate? What about power wise? I'm guessing the 4port would make more ported or net?
Thanks, Ed
