L-jet for 2056 Options

[TargaToy]

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?

The Ljet system would likely work pretty well with no changes. No need to increase fuel pressure or get bigger injectors. Just address all the standard Ljet problems: pay close attention to vacuum leaks, make sure the resistor leads aren't broken, make sure your dual relay is OK, get the injectors cleaned, verify ALL of the electrical connections on the engine loom. BTW, you should use the distribulator and fan from the 1.8liter car. (The 1.8liter fan has the timing mark in the correct place. If you use the Djet fan, the timing mark will be wrong.)
