Weber DCOE .PSD and .AI files
I'm looking into adding either an ITG Megaflow JC50/40 or Pipercross PX600 sausage-style air filter to my 18R-G.
I need to buy a blank baseplate and cut holes for dual 45 DCOEs.
After a bit of Googling, I couldn't find a vector or CAD file for the bolt spacing etc, so I've decided to make my own (and why not make a gasket?).
Using the technical drawings I could find, and measuring my own Weber 45 DCOE's to confirm, here's what I've come up with.
To allow room for slip-in ram tubes, the choke hole diameter on the 45 DCOE gasket is 50mm. For 40 DCOE's, it would be 46.5mm.
Carb-Center Spacing for Dual DCOE's on an 18R-G
By the way, for anyone else making a baseplate for dual DCOE's/DHLA's on an 18R-G (using the short manifold, 17111-88231): the carb center-to-center spacing is 199mm (or 109mm from the centers of choke #2 and #3).
You'll also need a "RH" offset to clear the brake booster on right-hand-drive models. Meaning, choke #4 (rear of engine, on the left of the baseplate) is much closer to the edge of the baseplate than #1 is.

This all got started when I purchased a couple of JDM brochures for my RA28 Celica. I'm now completely obsessed with old Japanese cars. Basically, if it's Japanese and had chrome bumpers, I love it!
