Iv been thinking about buying another r34 but get a gt-t model. problem is im on me p's still. is it possible to take the turb off and get a new exhaust header built. Would you have to change the ecu.? if so are the wiring looms the same in gt and gt-t models.?

other thought was to buy and drop a n/a motor in the gt-t body and drive that untill im off me p's. then in the mean time i have the gt-t motor to play with. can rebuild it and when im on my opens i can drop it back it.

will the wiring harness be the same though.?

i imagine this would of been answered before.

thanks

car will still be illegal to drive on your p's. Will still be registered as a turbo vehicle and the cop is not going to care if you 'took the turbo out'

oh right.. i didnt know this just thought if it had no turb it would be ok haha. definitely no way around it then, gotta wait..

cheers for the info guys.. and yes im new and im still figuring out how to drive this webpage

you got me on a good day, so i won't just post things like the above people (normally i would). i'll explain to you why it is a bad idea to pull the turbo off. turbo engines run lower compression than the non turbo versions. this is to account for the extra air being forced in by the turbo. this means that if you pull the turbo off a turbo motor it will make less power than the non turbo version. so what you would end up with is a car making roughly the same power as a hyundai excel (and i'm not joking) but weighs about 300kg more.

as for dropping a natro motor in its place, well as people have said, the car is still registered as a turbo, so no dice. plus the fact that it's a waste of time and money.

thanks mad082.. i can see why.. and i didnt think it would ever work but my dad keeps saying it would and i keep telling him why it wont so i asked :D. i also told him it would be much more fuel Hungary due to the less compression in the combustor.

as people have said i dont think i will wast my time.

though.. if the motor was changed to n/a and it had an engineers cert and vic roads had it changed, legally wouldnt this now be a n/a as the n/a motor is now registered to the car.?

the reason im asking is because i wanna get another 34 as my 34 has all the sat nav sh*t and pop up screen in the dash. i want a double din unit in there and the dash to be flat at the top. There is no reason i cant change it i just cant be bothered doing it and cant get a hold of the parts.. so i want to get a 34 that dont have the sat nav option and has the double din and all :D..MY RADIO DONT EVEN WORK.. its the worst

might just try hang out the 12 months and get the tt....awwww

thanks again guys

Talking from personal experience.

It will still run, and will run like sh*t.

Also important to note that the RTA has gotten smarter over the years and will still see the car as a turbo car as they go off the chassis, regardless whether the turbo is still in there or not.

so i should do it the other way and wack the turbo in my n/a :D haha

i would see the motor swaps as a project as 1 would of been something to work on.

and changing the stereo isnt the hard bit its finding the shrouds from other cars thats hard to get

pretty sure even going through all the work of changing the motor and getting an engineers cert would still be illegal for other reasons than posted above. i may be wrong, but i have a feeling that replacing the engine with a different one that the car originally came with is classed as an engine mod, which P platers aren't allowed to do

just to clarify what i mean by "different one to what the car came with", replacing a rb25de with another rb25de from the same model car is ok, replacing a rb20de in a r32 with a rb25de from an r33 isn't allowed

      Auto Electrician Workshop Recommendation for Reverse Camera Not Working CKV36 (SYD or WOL)

      By JoVo · Posted

      Update: Tunehouse looked into the problem and identified a wiring issue between the camera unit and the connector. They managed to get it working , but did warn me at some point it will stop working again. From their perspective it is unserviceable and will need replacement. They did some research and found that the new replacement camera would be Approx $1400 supply only (their fitting cost would be $190) . They did provide the part number (28442-JL05B) and a quick google of the part number shows that these are rather expensive brand new (seemingly no longer in manufacture) for the places that still have them in stock, with the used option potentially presenting  the same issue down the track at some unknown point. They are happy for me to supply the part so that they can fit it. Decisions, decisions... I can definitely recommend Tunehouse (thankyou Vee37!). Cost for the diagnosis was as quoted  ($190) , car was ready on time and communication was top notch. Their workshop is super clean and modern, and there was plenty of car candy parked out the front on the day I went.   Would definitely go back.

      to fix the voltage drop issue I swapped out the old 150amp alternator which turns out is a brand known for having issues and replaced it with the black 180amp alternator beside it

      A31 Digital Climate Control

      By S1_C34 · Posted

      For anyone interested, the Way Back Machine has that Japanese website archived with pictures, etc: https://web.archive.org/web/20051023225805fw_/http://www.a31cefiro.com/air_con.htm "Simply swapping the wiring of the harness will not allow it to function properly. For the outdoor air sensor and sunlight sensor, disconnect the wiring connected to CN1-11 of the air conditioning harness from the harness and connect the sensor side wiring to earth. For the indoor air sensor, disconnect the wiring connected to CN2-3 of the air conditioning harness from the harness and connect the sensor side wiring to earth. The connector PIN numbers listed here are the genuine A31 PIN numbers. To avoid incorrect wiring, check with a tester before wiring. Also, disconnect the wiring in a location close to the sensor. The disconnected harness side wiring will not be used, so be sure to insulate it." Wish someone sold a conversion harness to just plug-and-play a Kouki 180sx digital climate control into C33/A31. I'm decent with wiring but feeling kinda lazy about taking this on. Edit: Did some more digging and found a helpful Minkara blog post about the conversion as well: https://minkara.carview.co.jp/userid/1831116/car/1360568/2284209/note.aspx "After installation is complete or the battery is replaced, you need to go into self-diagnosis mode and set the internal air recirculation. The way to do it is to "hold OFF with the key on for more than 5 seconds, set the number to 5, then press 卍→C." ↑↑↑It probably won't make sense unless you actually try it (・∀・)." Lol wtf
