We are converting a stock 2 liter 4 cyl from D jet to Webers. My gut is telling me a 40 IDF with 32mm venturis is the correct starting point. I am considering purchase of a complete set of 44 IDF's, but are unable to locate 32 mm venturis. Assuming 32MM venturis can be found are 44 IDF"s too large for a stock 2 liter?
thank you |

You want 40's. With that engine the vacuum signal in 44's is going to give you problems. It will probably run very well with 40's and 28mm chokes

You want 40's. With that engine the vacuum signal in 44's is going to give you problems. It will probably run very well with 40's and 28mm chokes (IMG:style_emoticons/default/agree.gif) Especially if you are running stock compression and cam designed for FI. A properly tuned D-Jet system works very well on a stock and even slightly modified engine as many have done. Think you'll find over time carbs will make a cool noise, but not really produce any additional power and reduce fuel economy. |
