Carburator conversion

[keldore]

Ok I have been thinking about my f22 build. Im leaning towards NA, prob 11.5-12:1 comp. bisimoto headwork with valvetrain, and a webcams stage 2 regrind. Thinking about engine management is making my head spin, I was wondering if anyone has fit motorcycle individual carbs onto a F22ax or maybe even a weber 38/38 downdraft. I have searched on google for a carburator manifold for this application with no result. Thanks.

Get ahold of Bisimoto. Bisi used to have carbs on his race engine before he went to itbs and standalone ems.

why not get a chipped ECU, a laptop, and a rom emulator? takes 30 min to install/connect everything. then just drive around and datalog, then pull over and adjust your fuel map on the laptop. then repeat to fine tune things. done. less headache IMO

and for the carbs they use tb's off a bussa or gsxr for the j/y itbs

even with itb's you will still need a ems
i guess you can go old school with so weber carbs but good luck finding ones cheap and then you will have to mount them to a flange. and after it is done i don't really know if it will be worth it


i don't know if the f18 was cararated or not but might be worth looking into i don't even know if it will bolt up or not if it is

When you say chipped ecu do you mean a Hondata s300, aem, etc.. Ive looked at a few, what are the pros/cons of each. I know the hondata is def. cheaper than the aem, but from reading the aem looks alot easier to use and more plug and play.

for a naturally aspirated application, you can be anywhere between about 11.5 and 13.5 AFR at wide open throttle. That is a pretty BIG gap where your engine is completely safe. If you know how to use a computer keyboard, you will be able to get it into that gap in about 20minutes and another 20 minutes will get you even more precise ratios

i mean a stock OBD1 Civic ECU that is chipped. you can chip it yourself if you buy a chipping kit and if you are good with soldering. or you can buy one that is already chipped, it usually runs ~$150.
you don't need Hondata because fortunately there is free tuning software out there

Thanks, what model # of civic ecu am I looking for? and how do I know if its been chipped etc.. can I goto my local speed shop or do I have to look on ebay etc.. Im learning more and more each day.

So if I can find one of the ECU's on the list any of them will plug into my existing harness... I wish there was a good tune shop around me to do the whole chipping/laptop hookup thing. Its not registering correctly in my brain.

Well if you can fab up some carbs onto your f22, then this should be simple. You don't need to tune it yourself, but you can chip it yourself.

I offer chipping/tuning services. You can email me at crzy.tuning@gmail.com for more info.
