Start with research. There are a few threads on here and other datsun forums outlining the project. Then ask specific questions. You will get way better help doing that, than just a generic "can you help me"?

 

Or better yet, abandon the efi swap as clearly not worth your time and sell the stuff to some tool with more time than sense. Namely, me.

Well you need all the EFI sensors for this to work properly. Everything should swap over including the exhaust manifold with the O2 sensor in it. You really need the head swapped to have the cylinder head temp sender. Its located near the exhaust side #1 spark plug and I doubt the carb head has this on it. That's something you must look into. Throttle cable probably needs to be swapped also for length, and you need a high pressure fuel pump and filter.

*4-6-8 Injectors (225cc-300cc-400cc) for N/A or Turbo.

 

*Crank or Cam angle sensor setup

 

*60 psi fuel pump + Tank

 

*MicroSquirt or MegaSquirt ECU system 

 

*Wide Band O2 sensors

 

*MAP or MAF sensor

 

*Throttle Body with TPS 

 

*IAC valve

 

 

 

These are just a few things to start with.

So you have the wiring harness and ecu? Do you have the various sensors and injectors too? If so then all you need to do is get a high pressure fuel pump and wire it in with the efi and fuel pump relay.

I've swapped a Z20E in my 720 and it wasn't hard at all.

i swapped a KA into a 720. hardest part was power steering stuff for some reason

 

This is what I'm currently in the process of doing - my swap should be completed in the next month at most.

 

When I do go ahead with the swap I'll have a full guide on how to do it posted on here for those interested - may be easier than the Z24 to Z24i.
