just pick up a set of ITBs for a CBR 1100, cut off the flange on an old IM, and take it to a fab shop to have them weld runners on it like that. guaranteed to be cheaper, and you dont have to deal with some ghetto e-thug
Most home made ITB setups use the stock injector location for the fuel injectors. Bike ITBs have injector location right after the throttle plates. You could make a vacuum log that bolts or glues into the ITB injector bungs. Remember you need a vacuum source for the brake booster and map sensor.
The EACV is meant for one throttle body, not four. Are you running Crome or Uberdata? ITBs and the stock ECU will run like shit. Get your ECU chipped and run Crome. Then you can run ITBs and not have to worry about the EACV or IAT sensors. Plus you could tune your D15B to run right with the ITBs and actually make more power. Honda Tuning's Dru Barrios put ITBs on a D16Y8 and gained over 20 whp!!!!:alky:
The motor has a stock block and head! :shocked: The motor baselined with 107 whp and 100 ft lbs of torque. With the ITBs and no tuning he got 129 whp and 113 ft lbs! The article later said he was able to tune out 142 whp and 120 ft lbs of torque with Uberdata!:bigrofl:
