Since I'm in the process of rebuiling my 2.0 engine, I was wondering why 914 high performance engines use 44 IDF carbs instead if 48 IDF's or IDA's. I'm not trying to build a race car or anything to much but want to upgrade my 40 IDF's.

IMHO you want your 40's with 38 venturis. If you are raising the displacement and going with a more radical cam, you would want to go with larger venturis.
The Bigger=Better school of thought does not apply to correctly matching a carburator to your 914 engine. |
