Porting job coming along nicely... - ZR-1 Net Registry Forums

Paul Workman · 03-29-2009

With some pointers and techniques gathered from Marc H at yesterday's shin-dig, my IH porting time dropped from 3-1/2 to 1 hour each (today). I finished the first one, and here's some pix, if y'all R interested...

I'm following an established recipe, least anyone accuse me of being a "carbide cowboy" as flyin ryan likes to say. Here you're looking down teh barrel of the IH from the top, going toward the head. That big boss in the primary side is gone and a 36mm ball drops thru the port like poop through a goose!. The secondary, due to the injector seal being on the tip instead of the shank, requires a small "blip" in the runner (seen in the pic below).

This view from the head side, looking up at the injector (ports).

And the overview shot...

One more IH, and then onto the heads. Then to the headers/exhaust after that. Oh, I got the itch bad now...Much worse after seeing Keith's car yesterday!
