The bottom mounting plate for my Weber partially covers the intake port for the auxillary valves.
Should (or can) I expand the hole or modifey the mounting plate?

Thanks,

Todd

The CVCC port needs to be fully open. But you are not allowed to modify the manifold. So modify the adapter plate to allow flow into the CVCC port.

Thanks Bill,

I appreciate the fast response.
You Soddy Daisy folks really know your CRXs.

Thanks again,

Forgive my ignorance, I am new to the Honda, front drive and ITC stuff.

The Carb is listed as a 3bbl as stock. Can the 32/36 DGV be used?

Thanks,
Mike

Mike,

The DGV is allowed. The GCR lists about 5 optional carbs that cab be substituted for stock.
All are are Webers downdrafts except for the Holley 5200, which is basically the same thing.

Of course the Weber doesn't have the small "third-barrel" to feed the CVCC.
That is where I had to modify the mounting plates.

If you go with the Weber, I'd check to make sure the plates are designed for the CVCC.

I believe the hot weber for a front drive car is the 34/34 DMTR. This is what I run on my ITC CRX.

The 32/36 was designed for a rear drive engine mounting and unless mounted sideways, I have heard that the float bowl will starve when cornering. Perhaps someone has a fix for this...

At the 2007 ARRC, first gen Honda CRX's finished one-two-three.
First place had an original Honda carb, and new lap record. Runs so good it can be driven on the street.
Second place car had a 32/36 Weber, and time just a small fraction slower.
Not sure what Jinx was running in third place car.

I agree with the poster above that head prep is most important, but the cars in first and second place at the ARRC didn't find the use of new rockers necessary. If they are still in spec, run them.

Jinx had a modified stock carb on his car. The fourth place C car also was running the modified stock carb.

Thanks for the feedback! Looking at the GCR again showed my error. I was confused with the 3BBL vs. the multiple carbs.

Thanks!
