I have done this with fuel injection on a VW engine with good results. I have witnessed comparative tests with Weber carbs, the EFI does much better with HP and response. See :http://www.aircooledtechnology.com/kitcarlson.htm You might be able to use the throttle bodies from the early T1 2.2L mopar 4-cylinder turbo cars. They are fairly inexpensive since some upgrade to the T2 manifolds and TB. There is a www.TurboDodge.com forum, you could WTB the TB in the classifieds.
