I had another topic going regarding my plan to build a 2056 from a spare 1.8 motor. Initially, I wanted to find out what was necessary to make my existing D-jet on my running 1.7 work with the future motor.

I learned that I need quite a few 2.0 D-jet components to make it work...and then from what I understand in reading Jake Raby's data on the 2056, I'll still max out at around 115 hp with the FI.

So if I were to revitalize the L-jet system from my spare car instead (a 1975 1.8), would it be possible to get the 120-125 hp a carb'd 2056 makes?

What tweaks exactly will be required to make the L-jet perform safely, and correctly? I have read that the fuel pressure may need to be raised. What are the other considerations and can they be handled by a competent DYI-er?

Run the LJet but you will have to adjust the AFM after its all up and running if you build a 2056 with a Raby cam. The stock setting will be too lean!
HP you will max out at 115hp with the 9550 or 120 with his newer cam, forget using the carb cams as the Ljet won't like em. 115hp is plenty with smooth power....the Ljet FP must be used and the dizzy is nice too.

This isn't the place to answer this question..

If you have viewed my camshaft/ valvetrain presentation you'd know that **I** choose the best cam for your application based on a data sheet that you fill out after your camshaft is ordered.

I do things much differently than others, for a very good reason.
