Hi folks. I have a custom Lotus Seven like roadster with a Holley 650 double pumper carb. I'm sick of it... Would like to install FI. The engine is a five letter street ported 13b.

I can do some simple maintenance tasks and simple repairs, but if I do this myself, it will be a stretch. So I'm looking for a system that might prioritize simplicity over everything else.

Which system would be the easiest for someone like me to get up and running? Note there is no factory wiring harness.

Thanks!!

Since you have a holly carb something like this Holley EFI 112-588 Universal 4BBL 1000CFM Throttle Body should bolt right on so you can keep your current manifold. I think this will only work if your engine came from an originally FI car. In which case you can use the primary injector locations in the center iron. If it's an old 13B prior to fuel injection there are companies that make 4150 flange throttle bodies that have fuel rails and injectors on them for throttle body injection. Something like this Pro-Jay 8 Injector Low Profile 4 Barrel Throttle Body 1360 CFM – Pro-jay.

Then you'd need a standalone. I'm new to that world so I really don't have a suggestion. I'm about to begin the process of installing a Fueltech so I can't attest to the difficulty since I've not done it yet. I hear good things about Haltech as well. I think either one make a product that will work for you. Fueltech has this but it's not cheap. FuelTech FT450 13B Rotary complete package. - FuelTech USA Haltech may have something similar. There are others as well but don't know much about them.

Thanks!!!
