Oh duh. Ive sync motorcycle carbs before, and i forgot that these cars HAVE motorcycle carbs. lve never used a synchrometer and i dont care to spend the money on one, but its not hard. I just simply don't believe i need to sync them.It's not hard but you'll need a synchrometer and a NDIR CO meter to do it properly. To balance the carbs, run engine to operating temperature, remove the air cleaner and the mesh funnels, measure the air flow with the synchrometer, then turn the adjusting screw until air flow is the same for both carbs. I use the STE Synchrometer type SK.

To properly adjust the mixture screws, you need a NDIR CO meter, but those are expensive so you could fudge it by doing what this fine chap demonstrates in this video:
I just got a new pcv valve since currently there is not one and the vacuum line is plugged directly into the valve cover. 2 dollars for that little thing! I was happily surprised. They didnt have an air filter, so i just picked up a glasspack instead so i can fix the whole "running open headers and getting angry stares" thing. Also, a 2 1/2" exhaust would be fine right? I know the optimal upgrade from factory pipes is 2 1/4 but they didnt have a 2 1/4 cherrybomb on hand.
And i didnt know how much power these cars had. I was looking at an intercooler for 200 smackaroos on the old marketplace, told the guy its going on a prelude, and his entire demeanor changed and he started talking like he knew me for a decade. He goes "if you get that one, I'll throw in this one for free. The wife'll just throw em away anyway"
