Hey guys,

Just wanted a bit of advice on an engine swap.

So im still on my p's and have a few months left.

Looking at buying an R34 GTT and doing a rb25de conversion on it since im still on my p's and building the rb25det engine.

I can get my hands on a rb25de engine from a stagea for quite cheap.

Just wondering would it be straight bolt in using the gtt's gearbox??

and how different is the wiring loom between the two cars?

Thanks.

Vehicle is still registered as a GTT so in the eyes of the law on paper you're still driving a prohibited vehicle.

Your best bet would be to buy a GTV which comes with all the GTT bits minus the turbo, and then do an engine swap later.

Also you'll need to modify the sump on the Stagea motor for RWD if you plan to go that way.

After re-reading your post, only a few months to go? Spend that few months doing more research, even buying parts that you might want to modify your GTT with etc... I'm sure that all would agree that it will be worth your wait to legally get a GTT to begin with rather than stuffing around with all this motor swapping, that and 2xmotor swaps will set you back around 2.5k.

If you want to build the motor though, perhaps buy the GTT now, and spend those few months building the motor to have it rady in time for being able to drive it. These things take time to research, buy, carry out the labour, then tuning, then re-tuning after running in the built motor. If you have a parent that can even drive the GTT for the run-in period after building the motor, it will be all the more fun once you have it good to go and off your provisionals.

It wont fit as easily as you want it to. The 4WD RB engine mounting will need to be stuffed around with, the engine mounts and rails on any skyline that has a RWD RB in there needs fit has some modifications to fit it. The gearbox would bolt up and the engine harness is fine. You would waste a lot of money to fit an engine that wont simply bolt in easily then take it out soon after.

N-DAWG is right, because its illegal you can just buy a turbo car put it in your garage and work on it because you have time for that........so much easier, so much more money saved.

      R32 Sedan - Grip and Drift (have my cake and eat it too build)

      Looking at finally painting and installing my R32 GTR wing I bought back in 2018. I got two quotes: Quote 1: $880 includes: wing, spare boot, holes welded up prep/paint. Pro: full boot with wing AND hole-less boot with lip i can swap between Con: $$  Quote 2: $330 wing only. Pro: cheaper Con: lose my (relatively) rare no holes sedan boot Also to consider I do plan on painting my whole car at some point "soon" (been saying that since 2018) Anyway Enjoy these All Japan Day 2025 pictures of my 4 door, still rocking the Calsonic Livery! Rolling in Interior shot Matching Peer Pressure Racing overalls are pretty cute ngl. This year was a hard 1990 cut so I got to be over with all the older cool stuff Next to arguably the best car there. A mighty S-Cargo

      I personally would run 2x from the cam covers into the catch can, 1x sump vent to catch can (would mount this at a low point of the catch can, so it can also act as a drain). I would see if you can run a -12AN down there to improve venting and also draining. The head drain thing, just drain that back to the sump on the other side. Catch can to be vented, unless you plumb or back to the intake.

      Yeah the head "drain" is rather a sump/crank case vent. My catch can stopped filling up after venting the sump to the catch can. I have 4x fittings in mine, which is about 5Ls. 2x cam, 1x sump vent/catch can drain, 1x fitting back to the intake and a massive breather which can be blocked so it's a fully sealed system.

      Need AC Compressor for R32

      By Zabuza · Posted

      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.

      V36 2008 Coupe Wiring Differences with Android Screen

      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
