1uz to nissan 240sx: Basic guide

[DirtyOldMan]

There are more and more people trying to swap the 1uz into the nissan S13. I found this write up on how to swap a 2jz into the nissan so figured i would switch things up to the 1uz plugs and ect.

Can anyone confirm if this little write up sounds good?
I just need help on alternator, and do the injectors get their pulse when the EFI get switched on and is that all done thru the ECU?

Am i Missing anything?>

[e9 connector
[/B][pin 1- IGSW Ignition Switch] needs be switched so your ecu knows when to come on and isnt running all the time no need for relay u can tie into one of the nissan ones under the hood


[pin 6- Check Engine Light] is your check engine light, hooked up behind the instrument cluster one wire to the bulb.


[pin 24-M-REL EFI Main Relay] is the efi relay that needs to run to your sensors

[pin 31, and 32- +B,+B1 EFI Main Relay] need to be tied together and run to a 30amp relay this is what powers the ecu and it needs to be switched
I Believe this is the same thing as:

You need switched power to EB2(2). This is a black and orange wire.
You need switched power to EB2(3). This is a black and red wire

[pin 33-BATT, BATTERY] needs to have 12v constant power

[e10 connector]

[pin 69- E1-ECM Ground] needs to be grounded


[pin 65- E2, Sensor ground] ground to chassis


[pin 79,80-E01,E02- Power Ground] ground to chassis.



[pin 76-NSW neutral safety switch] CUT on the e10 connector or you will be rev limited at 5k rpms (has 12+ when in neutral )

[PIN 77-STA] Tells Ecu engine is being started - connect this wire to the starter relay output, 80amp relay best., or the black starter SOLENOID wire, not the main cable.

* (E11) is grounded.
* (E2) is grounded.
* (E02) is grounded.
* (E01) is grounded.


IL1 #8 should be spliced with IL2#6 on the engine side thats it for the engine harness

Im also doing this swap into my 89 240sx. It would be great if someone that has done the swap would chime in.

I'm putting a 92 LS400 engine into a PS13 Silvia, so just subscribing to this thread in case any more info comes up. Meanwhile, I'm off to try and find some ECU pinout pics.
