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 |

My 5800 rpm swag was off. My 914 spec says max hp is at 4900 rpm. This'll decrease the main venturi size to about 32mm. So I would recommend 40IDF.
I forget how underpowered the T4 is! |

Yes, with dished pistons/low compression it's near impossible yp make decent HP. If I live long enough and/or have some spare time I would like to try a twin turbo setup. I have not seen much on this board with this topic. Yes, my gut is telling me twin 40IDF's with 32mm venturis will work well with a stock 2 liter. 500cc/cylinder volume |
