Schlasken Posted October 3, 2003 Share Posted October 3, 2003 has anyone done this? i`m wondering about using the stock one to keep the cost of the project as low as possible (yes i know its not a cheap swap). i`m not planning alot of tuning and i really dont need a expensive aftermarket computer.

Stealth-Z Posted October 5, 2003 Share Posted October 5, 2003 This is the address to a site that I am using for inspiration of my project. http://r31.fcpages.com/rb20.htm My plans are to use the entire stock Skyline wiring harness in my Fairlady-Z. As my Z is RHD, no major modifications should be necessary. I was very careful about removing the engine and trans from the Skyline front clip without cutting any wires.

Guest 81na ZX Posted October 5, 2003 Share Posted October 5, 2003 Do you mean the stock RB wires and computer or the stock L wires and computer? There is no way the L-series wires/ECU will work with the RB engines... Quote Link to comment Share on other sites More sharing options...
Stealth-Z Posted October 5, 2003 Share Posted October 5, 2003 My plans are to use the stock RB wires and ECU. Everything from under the dash to out the fire wall. Quote Link to comment Share on other sites More sharing options...

Guest 81na ZX Posted October 5, 2003 Share Posted October 5, 2003 LOL Ya, it'll work perfectly fine. You might need to custom mount the ECU and/or lenghten the harness wires and/or cut a new firewall hole though. Quote Link to comment Share on other sites More sharing options...
Guest 250z Posted October 6, 2003 Share Posted October 6, 2003 I've used the stock ECU on my RB25DET conversion Quote Link to comment Share on other sites More sharing options...
Zardilla Posted October 10, 2003 Share Posted October 10, 2003 I have the stock RB26 ecu and wiring in my 240Z. I would recommend getting a front clip so as to get all of the proper fuses, etc. Fortunately a mechanic in my area knows skylines and nissans in general so with his help we got the car running (but with a few issues to yet sort out). One thing to consider is checking all of the critical circuits before installing (knock sensors, MAFs, TPS), it will save you time and you'll be confident that everything works fine. I had to chase down a few breaks in circuits given the harness was 10+ years old and had seen some abuse. If you do want to turn up the boost, change injectors, switch to MAP from MAFs then either be prepared to buy a remapped ecu or a flexible aftermarket computer like SDS or a piggy back computer like Apexi FC.
