Hey, I just threw a Weber 32/36 DGEV on my 2tc. Weber carbs direct sells the kit with everything you need. You don't need to run a regulator if your fuel pump is near 3.5 psi. (My electric pump puts out at 4.5 psi, I have no problems with flooding, etc.) It won't really matter anyways because all the regulator does is regulate (duh) the fuel going into the bowl, but what gets taken out of the bowl is controlled by acceleration, etc. I bought a $35 regulator at autozone, and it did nothing but leak and not work. Save your money.
One thing to make sure to note is that you only need to run a fuel inlet line. The stock 2tc carb runs an inlet and a return, and I thought I'd be a wise guy and run the return line. This was a mistake. Power bogs out (fuel supply runs really lean) at any mid to high range RPM and your car will start to dance, but not the good kind. Just plug the return line (fender side) with a bolt and a hose clamp, or pull the line off altogether and plug it at the end of the hardline.
Other than that, it's a pretty simple swap. Took me a while to figure out how to get the baseplates and adaptors in order, but trust me, everything you need is in the kit! Don't use anything off the old carb setup. In other words, adapt the car to the carb, not the other way around.
If you have any trouble, the troubleshooting guide they give you will be indispensable. This was my bible for the last month. Good luck!
Also, are you planning on running a header to let the exhaust breathe better? If so, what are you going for?
