Thank you for the tips. The B210 will be moved to my house this weekend so I will measure everything. I figured that the dual SU setup wouldn't fit but I've never seen SUs up close so I didn't know how large they were.

As for cutting, I prefer not to cut my firewall. Eventually I will either move the master under the dash or I will spend the extra cash for the universal wilwood pedal box and masters.

Eventually I may choose to do a swap, but I really want to spend some time figuring out what the a-series has to offer. I'm starting with a decent setup. My B210 has an A15 with H89 head. I have a modest goal of running 5-9psi of boost from a screw supercharger through it, but that is a long way off.

For now I just need to decide on a carb setup because the stock hitachi is completely shot. It looks like the most viable options are either a single DCOE or a 32/36 DGV. I know the DGV will hold me back once I start building so I was looking for a better alternative using SUs. Thanks for all of your input. One day I hope to have the money and time to fit a CA18DET in the B210 and move the A15 setup into a 1200, but I have to find a 1200 first :P
