Type IV upgrades and FI, Where's the cut-off to carbs? Options

[boxsterfan]

At some point, my motor (1974 2.0L) will need a rebuild. I'm not going to go the /6 conversion on this car. If I rebuild the motor to a 2056 or 2270 displacement, can I still use the FI system (D-jet)? Or is there some spot in here where it is better to switch to carbs? Or if I wanted to have FI then switching to L-Jet instead?

Happy to do some reading if you have it... (IMG:style_emoticons/default/chowtime.gif)

For kicks... I've got a 2056 with a JR cam and Ljet. I believe it was set up at 9:1. Runs real well after the first 60-90 seconds after a cold start, when it would like to stall without additional pedal. Feels like it has mucho mas cajones than the 2.0 I had...

I've driven Chris' 2270 with Ljet. Even more fun. I feel the Ljet is just a bit more "modern", and seems to be a bit more adaptable to a larger displacement engine.

these are simply my SOTP impressions...

That's my impression also about L-Jet....just a bit more modern. In addition, it seems to have way less number of sensors ($$$$). I'm not quite sure if the AFM is adjustable or not? Some old 280Z's I had could have their AFM box adjusted with a simple turn of a screw.
