So heres my problem,

got a S2 RB25DET to put in the R32gtst of mine, using the R32 loom and microtech LTX16S ECU. Then I realised that the coils on the S2 are different as they have the igniter on the coils where as the S1 are the same as the 20 coils...If I cant swap the coils over is there any way to get around it without using the 25 loom?

Thanks

Just use the RB20 coils otherwise you will need to rewire the connection of the RB20 loom to the RB25 coil pack loom. I have attached a photo of an RB25 S1 loom I rewired to suit R34 coil packs (with built in transistor in the coil pack). Unfortunately you cant see the connector but it is a single 8 pin black plug.

RB20 coils are rooted, got brand new splitfires for the 25. so I can just splice the rb25coil pack loom to the rb20 loom and it should be good?

thanks heaps

Modify the RB20 loom with the addition of the mating 8pin plug to suit the Rb25 coil pack loom. You will need to remove the RB20 transistor plug and 3pin (power,earth and check connector) plug and join them to the respective pins on the 8pin RB25 plug (you will need to source this plug). The wiring diagrams will help.

In addition to this, I am currently doing the exact same conversion, aside the coilpack issue as I have my complete rb20 still avaialble for parts is there anything else that would need to be replaced so the rb20 loom and ecu could be used with the Series 2 RB25..???

      I would just put EBC back on the "I would not use their stuff" pile and move on.

      Can I suggest you try EBC directly again and link them to as many competitor catalogues as you can to show their listing is incorrect, eg https://dba.com.au/product/front-4000-series-hd-brake-rotor-dba42304/ If you have access to an R33 GTST VIN and your VIN, you could also use a Nissan Parts lookup like Amayama to show them the part number is different between 33 GTST and 34 GTT which may get their attention

      So i got reply from EBC and they just this site where you can clearly see those 296mm fronts on R34 GTT. I send them photos and "quotes" that 296mm are not for 34 GTT and they are too small. But it will be very hard to return them cuz nobody here knows 100% and they just copy those EBC catalogue :-D https://ebcbrakesdirect.com/automotive/nissan/skyline-r34

      From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
