Lockleaf Posted September 8, 2016 Report Share Posted September 8, 2016 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. 1 Quote Link to comment
datzenmike Posted September 8, 2016 Report Share Posted September 8, 2016 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. 2 Quote Link to comment
Mattndew76 Posted September 8, 2016 Report Share Posted September 8, 2016 *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. 2 Quote Link to comment
Charlie69 Posted September 8, 2016 Report Share Posted September 8, 2016 There is a write up on the web of a guy that had a carbbed Z24 720 truck and swapped in a Z24I. he covered it pretty well. Search 720 Z24I swap. 1 Quote Link to comment
jesusno2 Posted September 9, 2016 Report Share Posted September 9, 2016 i swapped a KA into a 720. hardest part was power steering stuff for some reason 2 Quote Link to comment
Spiff Posted September 12, 2016 Report Share Posted September 12, 2016 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. 1 Quote Link to comment
Crytek89 Posted September 12, 2016 Report Share Posted September 12, 2016 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. 1 Quote Link to comment
Charlie69 Posted September 13, 2016 Report Share Posted September 13, 2016 This is what I was talking about. http://nissannut.com/projects/z24i_fuel_injection/ Quote Link to comment
