I have a 1974 1.8l and have access to an affordable 2.0L GA series engine.

I am highly tempted to do a conversion. Due to special rate insurance I have I need to maintain fuel injection on the engine.

Where I need guidance is how difficult is it to convert the car from the 1.8L engine to the 2.0L engine and switch from L-jet to D-jet?

Mechanically I know this will be a piece-o-cake but electrically are there any gotcha's?

Thanks in advance.

Why go from L-Jet to D-Jet?
The L-Jet is much more reliable and parts are more available.
Keep your L-jet injection and electronics and just swap the engine. You'll only need to drill matching holes in the intake J pipes to match the 3 bolts on 2L as opposed to the 4 bolts on the 1.8L.

Keeping the L-jet would actually be my preference as then the car would be even closer to stock.

I am wondering why the did not use L-jet on the 2.0l. They ran D-jet all the way through to the end in 76.

More searching around has validated that L-jet can work on a 2.0. Still not clear if it needs some calibration as well as what injectors to use.

Very unanimous that when building a big 4 that carbs D and L-jet both do not work well and carbs or a modern EFI need to be used. This in not personally relevant to me at the moment.
