B16 on carb/s?

[sb3]

My mech friend have a B16A (without harness and ECU) lying around his workshop . I have seen on foreign websites , the B16A engines were fitted with Twin webers and Mikunis carb fitted. As for the VTEC solenoid, its powered via the gearchange shift lights ! I've never seen one locally though .

Any thoughts or inputs on these? What about the dizzy and spark plugs. Do we have to use the MSD coils to fire up the plugs?

The distributor have to convert to old carb distributor I think, the important part is figuring the trigger signals for the TDC (sourced from either crank/cam, can choose digital or analogue). That's the prerequisite for ignition advance.

Or skip alll that for old school vacuum advance/weight + springs ? using old school cam/crank TDC trigger :P

Another is running MSD's, but you still need a trigger signal from the old distributor location. I forget the actual number of pulses the trigger wheel in the ori distributor outputs, but if you're really into doing it, then I can probably look it up in the honda manual.

Not so easy to tune carbs for good powerband, since you have to consider emulsion tubes, venturis and jetting amongst others but a good experiment/project to do if you have the time.

The RPM solenoid trigger is pretty easy to do, connect relay to RPM meter shift light. set rpm limit so when shift light triggers, the relay sends 12V to solenoid, you have VTEC.

Thanks for the input bro, I'm a bit confused over the distributor , cam and crank sensor part though. If we are using the B16a Engine, how do we know the location of the TDC as the B16a do not have the extra length of cam to hook up the distributor ? Just for discussion sake b4 taking my wallet, will it work? Thanks again for the input, shiroitenshi.

The sensor to detect cam (which actually translates to crank position) is the wheel trigger after the distributor bearing.

B-series reads off the cam for their TDC/Piston position. Although some people say it's not as good as the crank trigger system, honda did it pretty good enough.
You can read info about various ignition triggers here.. or google for more.

It doesn't mean that you have to run haltechs though I just picked an example, any ignition system need a trigger sensor so it know when to start the spark, because we don't start the spark at TDC, but BTDC.

AEM actually makes a specific one, but can't guarantee that it works for all systems because different ignition systems expect different signals, but anyway, buying it complete sort of defeats the purpose when you're doing it on a budget or for DIY experimentation.
