hi guys im just wondering about how i would go about doing an engine transplant putting a GT-t engine in my NA r34 25gt.

i know buying a gt-t is a better option financially but i want to have an engine so i can work on it and then when im off my p's bang that monster in :P.

ok so my skyline already has the turbo brakes.

i should be able to get a GT-t loom ecu turbo for around 2k-2.5k

what else needs to be changed?

im also awear that the drivetrain will need changing but ill change that when it brakes. plus i think they're only 150 -200 from a GT-t wreck anyway :D

All answers would be helpfull.

Ps. i managed to get my NA coupe for around 8k with 116,000 kms (guy was going bankrupt) :P

you might want to add a 0 to the end of the price for a 'drivetrain' from a GT-t wreck, unless you are simply talking about the diff and not the gearbox. generally the gearbox sells for more than the actual engine.

as for what you need, look in the how to turbo a skyline thread. it has been covered many times. whether the engine is a neo or not is a minor detail. all the procedures are the same between a neo and a non neo.

Don't Gtt and gt have same trans

No, I'm 98% certain the one used in the N/A R34 is an RB20DET gearbox. The RB20DET gearbox can take no more than 220rwkW, so if you want more power then that, I would budget for a GT-T gearbox.

I'm pretty sure you can just use the N/A R34 gearbox depending on your power needs. Someone can correct me if i'm wrong.

Stock (factory) component comparison.

GTt > GTv > GT

2 varients of GTt and GT:

GTt and GTt-x

GT and GT-x

The difference between the "x" and non "x" models are strictly trim level with "minor" mecanical option. ie premium sound, privacy glass, front strut brace, rear wing, optional LSD for GT-x (handling pack)

RB25de NEO = GTv, GT

RB25det NEO = GTt

Regular brakes (Tokico aka hitachi automotive calipers) = GT

Big brakes (Sumitomo caliper) = GTt, GTv

HICAS = GTt, GTv

LSD = GTt, GTv, factory optional on GT-x variant.

4 speed tiptroninc automatic = GTv, GT

4 speed tiptroninc automatic (internally strengthened) = GTt

5 speed manual = GTv, GT

5 speed manual (internally strengthened) = GTt

note*

GTt, GTv: they both have the same rear suspension setup.

GT: Has the same suspension setup as an R33GTSt

is it an auto? trans cooler won't do much to strengthen the box (and won't do shit on a manual, don't think you can even fit one) as it comes down the the strength of the internals and generally not the heat. heat is usually more of an issue with constant acceleration/power, such as towing or drag racing where they load the gearbox up before launching, but even then it's marginal.

not too sure on shift kits, but i have a feeling that they may actually cause you to break something sooner. they put more stress on the gearbox. i could be wrong though.

hmm people say they actually reduce stress on the trans i know it sounds weird due to quick shifting one would think its kinda jamming the gears into place will it cost much to make the trans be able to withstand a turbo?

    • 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
    • Hi, is the HKS  Tower Bar still available ? negotiable ? 🤔
    • 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.
