If I were to convert the R33 auto engine RB25DET to manual, do I need the auto starter? Is it the same?

I searched but could not find.

Thanks

Also, what else is needed besides for these parts?

Flywheel and bolts

Clutch disc

Pressure plate and bolts

Is that about it? And sensor stuff?

EDIT: I'm not speaking about the whole car. Just the engine.

You will need these parts from your model skyline, eg R33

gearbox,

gear stick,

gear stick cover,

gear knob,

pressure plate,

clutch,

flywheel,

pedals,

pedalbox,

clutch master cylinder,

drive shaft,

g'box mount and cross members,

center console.

Also the R32 GTR uses one kind of wiring harness but in the GTS4 and GTS-t models there is four different wiring harnesses eg:

- A/T with auto spoiler

- M/T with auto spoiler

- A/T without auto spoiler

- M/T without auto spoiler

This makes it fun to do a conversion from auto to manual unless you have a manual wiring harness! although it is possible to use the A/T harness if you find the plug on the side of the fuse/relay box in the engine bay, this plug has only two thick wires going into it you need to connect these two wires together to be able to start the engine, (the A/T equiped vehicles have a ignition cut-out system) also the reverse lights need wiring too.

You're confusing me here.

I have an AWD R33 RB25DET with an automatic transmission.

It is an engine swap with a complete harness.

It is going into a US spec S13.

I live in the US.. no skylines here. Just wondering if there is a way to keep the auto harness and wire this up in the S13.

And what is a spoiler? When I think of spoiler I think of a wing on the back of a car....

Ahh... Sorry I didn't see that it is for a conversion.

Yes you can use the auto harness there will just be some wiring to be done, when you say complete harness does this include the Fuse/relay box in the engine bay as this makes the job heaps easier to do. There will be some wiring for the ignition as I am sure the bulk heads on the harnesses on the S13 will be different to the R33. If you plan to convert it to a manual you will need to do the wiring that I explained above to start the engine, or you can change the auto's Park/neutral switch to the neutral switch on the manual and this will also enable you to start the engine.

Also if you plan to run the standard engine management you will need to connect a few of the sensors as you stated above, these will include exhaust temp, radiator temp as well as a fuel pump control module and some more wiring if you want the ecu to control the fuel pump.

The auto spoiler is at the front of the skyline under the front bar, it was a factory option so not all have them. You probably call it an auto air dam?

Once again sorry I didn't mean to confuse you!

Well, I'll see what all my engine has when it gets to me and then I'll bump this topic up again.

I do plan on doing all of the wiring to run the car on the skyline ecu. Hopefully it works out.. I know it will be damn hard.

I'll get it all though, even if I have to piece it together..

Thanks.

Sorry just a few quick questions. I am pretty sure there were no RB25det AWD engines...... Except from the stagea. What car did they say this engine came from??

Also are you going to be making the s13 AWD?? Because that would be quite hard, but very cool.

Was the S13 silvia delivered to the US? I'm pretty sure the S14 was (with a different engine) but never never heard of the s13 over there, can you post a pic of what the US s13 looks like?

Sorry for all the questions, just interested, thanks.

Greg.

Making an S13 AWD would be insane... I wouldn't even try. This topic was created to get an idea of what it takes to convert the engine and wiring to RWD.

I don't know what my engine is from. Probably a stagea...

  • 1 month later...

nameless your on nico right? also do you think to can do alittle write up on the wiring part of the swap for the S13, also do you need to still need to do alot more work if you happen to find a RB25DET R33 GTST ECU you have to do alot more work like wiring the sensors and stuff

Yep I'm on there.

I'll be doing a write up on my swap in about 4-6 months. I guarantee it will be the MOST detailed one out there.. unless someone manages to come up with a very detailed one in the meantime. It will also include parts like converting an AWD sump to RWD and using a RWD gearbox etc.

    • Ok glad you clarified on the frenchy’s options , I was worried about if my oem hoses would fit the new compressor or not if I just bought the bracket/compressor kit ,  didn’t realize they also sold a larger full conversion kit. Hmm may just go oem in that case then to make it easy only because I plan to sell this car to upgrade to a 32 GTR or 34 GTT.
    • Right, here's a video of the basic operation at least.  This is what you can expect day to day when you turn the car on and it boots from standby.  The only thing from a media point of view I haven't gotten working is for it to autoplay plexamp when it turns on from standby (it works from cold boot) but that's more of a plexamp problem as it will autoplay other music players.  Also attached is my one stray cable.  It's part of the screen's wiring adapters but there's just nowhere for it to go in my car.  I've just now done a bit of research and found a matching port on a 2010-2014 head unit with BOSE.  Mine has no BOSE so that's that case pretty much closed I think.  Plugging in the Infiniti AC panel basically did nothing for me, so that's a dead end as well.  Next port of call is to mess with this CANBUS module and see what I can find from it.  I found this resource containing the DBC files for a 2010+ G37 : https://github.com/icecube45/Dash_InfinitiG37/blob/master/InfinitiG37.dbc I'll now have something to go from when I try to extract my CANBUS data so I can see if the HVAC Mode, Fan Speed, Temperature, etc. match and also the gear shifter position.  It's a pretty big assumption that it's just mismatched CAN signals but considering all the devices in the CAN network are talking to each other (AC can be fully adjusted just with no info on screen) it might be a safe one.  I will report back WhatsApp Video 2025-02-26 at 12.49.10.mp4
    • Thanks for that Paul.  Do you think if I posted a picture you'd be able to remember where it went? 
    • Sorry Duncan, I didn't get a notification for the replies.  Thanks for responding!  It's a full Android device, but does allow you to use CarPlay/AA as well.  This is the one I bought from NaviRS on AliExpress: https://www.aliexpress.com/item/1005006368602668.html?spm=a2g0o.order_list.order_list_main.111.59aa1802JDzQ0E - the 2K 8G-256G CAM variant but it seems to have gone up by £170 since I bought it!  My purchase was £307.14.   It's not the fastest thing in the world but performs perfectly adequately.  It stays on standby unless I disconnect the battery and let it power down, then it's just a fairly standard Android bootup time from cold.  The DSP Equaliser is very nice and made the standard stereo system sound pretty decent compared to the stock screen.  Perhaps I can take a video of it when I get a sec. It *allegedly* supports the reverse camera, but I'm yet to get that working.  It has options for reverse cam (a camera unit can be bought separately) or 360 cameras (also bought separately).  To be fair it doesn't seem to detect that the shifter was put into reverse but I'm working on a theory about this as well.  At the moment I'm going without which is a bit annoying considering the car is an absolute canal barge but so far I haven't caused any damage I'll grab a picture of the wire I'm missing later today when I can get outside.  My theory, by the by, is that not only is the head unit different, but the CANBUS network has different signals for the different years.  I think this because I have a spare AC panel from a newer Infiniti G37 (as opposed to my Nissan panel) which wouldn't control anything except the volume when I had it wired up with the stock system.  I'm going to throw it back in and see if the screen will respond to it.  I've just ordered an arduino CANBUS module so I can have a look at the signals going around the car and see if I can spot anything.  I'm thinking if I can work out what it's expecting vs what it's getting I might be able to translate and relay the signal back but so far just a theory anyway. I also found this on my travels, so far the only one that specifically matches my car: https://www.aliexpress.com/item/1005002822934280.html?spm=a2g0s.imconversation.0.0.33433e5fgttovi If you look at the picture of the before, it has the card reader slot, and the picture of the head unit is exactly the same as the one pictured in my original post.  I asked if they sell the cables separately but sadly they won't.  I didn't want to just buy this one because it's a super old Android version and only dual core - likely slow as hell. 
    • As above, you did refill the coolant and burp the system before running it again didn't you?
