Hello :blink:

Im trying to figure out a styline route for my R34 4 door. Does anybody know (for certain) what the compatability is between the 2 door and 4 door chassis?

Are the wings/bonnet/front and rear bumper the same on both cars?

front bar is the same, bonnet same

rear bar is not

wings? you mean front fenders? or side skirts?

- Front fenders the same - Pretty much everything up to the A pillar.

- Whole dash assembly the same.

- Front seats the same

- Front suspension, Rear suspension - the same (...but I've read somewhere - please don't quote me on this - stock front suspension on the sedan is slightly stiffer due to the extra weight when braking)

- Tail lights - different

- Boot - Different

- Rear bar - Different.

Eastbear have some nice coupe/GTR style bumpers and panels for the R34 4 door -> http://www.east-bear.co.jp/

To have the front bar bonnet off a gtr i beileve you have to replace the bonnet bar an fenders all in one hit.

Also the mounting points for the lights are different as far as I know, which mat suggest the fron uprights needs changing to do it all properly. Otherwise you can knock up brackets to fit the GT-R lights.

i think you will find the front seats are different from 4 door to 2 door.

i purchased a set of front seat rails for a 34 gtt autotechnia brand i think they were, sign said 34 4 door compatible, tried fitting and works out they are only for 2 door version. rang mob who made them and they said the 4 and 2 door are different, and they don't make 4 door version. bolt holes at rear of seat are the difference.

I have a 2001 turbo sedan with the update bumper and wanna take it off to fit a non turbo early model bumper :(

Is there a difference between early model turbo and non turbo front bumpers?

Or are people refering to the non turbo as the standard type then the turbo as the nismo option type?

Attached picture's for reference, the black one to me is the standard bumper with the lip, the orange one the Nismo option bar, then you get the later model round type?

Oh and seats 2 door and 4 door are the same, but 2wd - 4wd are different.

Seats are the same. Could be the rails that are different lengths - as you will need to move the seats more for coupes for rear passenger access.

And there's no difference between early model and late model front bumper fitment?

I have a 2001 turbo sedan with the update bumper and wanna take it off to fit a non turbo early model bumper :(

If you are running the stock side mounted intercooler - I do NOT recommend putting a non-turbo bumper - reason being is that it needs the side vent.

If you have a front mount intercooler - the non-turbo bumper will be ok, but may require some modification.

If you intend on keeping the side mount intercooler - your options are limited to the GTT bumper or nismo bumper - or if you're really keen a GT-R bumper, which means you will need a new bonnet, side fenders etc.

Non turbo doesn't have the vent on the side for the intercooler etc. Seeing as I don't want that, that's the reason for going non turbo.

Does anyone know if the tailshafts are the same between 2 door manual gtt and 4 door auto gtt? I need the rear section changed on my 2 door as the center bearing has collapsed on the rear sectin of the two piece tailshaft and I have access to replace it with a 4 door auto shaft and bearing.

Here is a picture of the part in question...

      Hey Dave, welcome aboard! Good to see another soon-to-be Stagea owner here. The wagons are awesome — plenty of space, still got that Skyline DNA, and loads of potential if you’re into mods. Definitely post up pics when you get it, everyone here loves seeing new builds. What model/year are you looking at?

      See if you can thermal epoxy a heatsink or two onto it?

      The other problem was one of those "oh shit we are going to die moments". Basically the high spec Q50s have a full electric steering rack, and the povo ones had a regular hydraulic rack with an electric pump.  So couple of laps into session 5 as I came into turn 2 (big run off now, happily), the dash turned into a christmas tree and the steering became super heavy and I went well off. I assumed it was a tyre failure so limped to the pits, but everything was OK. But....the master warning light was still on so I checked the DTCs and saw – C13E6 “Heat Protection”. Yes, that bloody steering rack computer sitting where the oil cooler should be has its own sensors and error logic, and decided I was using the steering wheel too much. I really appreciated the helpful information in the manual (my bold) POSSIBLE CAUSE • Continuing the overloading steering (Sports driving in the circuit etc,) “DATA MONITOR” >> “C/M TEMPERATURE”. The rise of steering force motor internal temperature caused the protection function to operate. This is not a system malfunction. INSPECTION END So, basically the electric motor in the steering rack got to 150c, and it decided to shut down without warning for my safety. Didn't feel safe. Short term I'll see if I can duct some air to that motor (the engine bay is sealed pretty tight). Long term, depending on how often this happens, I'll look into swapping the povo spec electric/hydraulic rack in. While the rack should be fine the power supply to the pump will be a pain and might be best to deal with it when I add a PDM.

      And finally, 2 problems I really need to sort.  Firstly as Matt said the auto trans is not happy as it gets hot - I couldn't log the temps but the gauge showed 90o. On the first day I took it out back in Feb, because the coolant was getting hot I never got to any auto trans issues; but on this day by late session 3 and then really clearly in 4 and 5 as it got hotter it just would not shift up. You can hear the issue really clearly at 12:55 and 16:20 on the vid. So the good news is, literally this week Ecutek finally released tuning for the jatco 7 speed. I'll have a chat to Racebox and see what they can do electrically to keep it cooler and to get the gears, if anything. That will likely take some R&D and can only really happen on track as it never gets even warm with road use. I've also picked up some eye wateringly expensive Redline D6 ATF to try, it had the highest viscosity I could find at 100o so we will see if that helps (just waiting for some oil pan gaskets so I can change it properly). If neither of those work I need to remove the coolant/trans interwarmer and the radiator cooler and go to an external cooler....somewhere.....(goodbye washer reservoir?), and if that fails give up on this mad idea and wait for Nissan to release the manual 400R

      So, what else.... Power. I don't know what it is making because I haven't done a post tune dyno run yet; I will when I get a chance. It was 240rwkw dead stock. Conclusion from the day....it does not need a single kw more until I sort some other stuff. It comes on so hard that I could hear the twin N1 turbos on the R32 crying, and I just can't use what it has around a tight track with the current setup. Brakes. They are perfect. Hit them hard all day and they never felt like having an issue; you can see in the video we were making ground on much lighter cars on better tyres under brakes. They are standard (red sport) calipers, standard size discs in DBA5000 2 piece, Winmax pads and Motul RBF600 fluid, all from Matty at Racebrakes Sydney. Keeping in mind the car is more powerful than my R32 and weighs 1780, he clearly knows his shit. Suspension. This is one of the first areas I need to change. It has electronically controlled dampers from factory, but everything is just way too soft for track work even on the hardest setting (it is nice when hustling on country roads though). In particular it rolls into oversteer mid corner and pitches too much under hard braking so it becomes unstable eg in the turn 1 kink I need to brake early, turn through the kink then brake again so I don't pirouette like an AE86. I need to get some decent shocks with matched springs and sway bars ASAP, even if it is just a v1 setup until I work out a proper race/rally setup later. Tyres. I am running Yoko A052 in 235/45/18 all round, because that was what I could get in approximately the right height on wheels I had in the shed (Rays/Nismo 18x8 off the old Leaf actually!). As track tyres they are pretty poor; I note GTSBoy recently posted a porker comparo video including them where they were about the same as AD09.....that is nothing like a top line track tyre. I'll start getting that sorted but realistically I should get proper sized wheels first (likely 9.5 +38 front and 11 +55 at the rear, so a custom order, and I can't rotate them like the R32), then work out what the best tyre option is. BTW on that, Targa Tas had gone to road tyres instead of semi slicks now so that is a whole other world of choices to sort. Diff. This is the other thing that urgently needs to be addressed. It left massive 1s out of the fish hook all day, even when I was trying not too (you can also hear it reving on the video, and see the RPM rising too fast compared to speed in the data). It has an open diff that Infiniti optimistically called a B-LSD for "Brake Limited Slip Diff". It does good straight line standing start 11s but it is woeful on the track. Nismo seem to make a 2 way for it.
