Hey guys.

I found a R32 GTS4 for sale with a RB25 from a stagea making ~350rwhp.

I have a few questions:

1. Does a GTS4 run the same gearbox and front axles etc as a GTR?

2. Where is the HICAS pump and reservoir, in the boot on the right side?

3. Is the rear diff the same in a GTS4 to a GTR? Ratio, strength, LSD?

4. Where is the ATTESA system ECU? Wiring and controlling components?

5. How does ATTESA system work, does it only send power to the front wheel when the rears start to slip? What is ETS?

6. How do you know if the system still works, like if fuse is blown or wiring is dodgy how can you tell? Does the gauge that says front torque split only read something if the system works?

7. Where is the high pressure pump that makes the front wheels engage power?

8. Is it common for 4th gear to crunch in GTS4 or GTR gearbox?

9. Is it worth putting in a GTR rear end in a RB25'd R32 GTS4, what are the advantages?

10. If ABS has been removed, does it change how the ATTESA system works?

11. Anything else you can tell me that could be useful.

Thank you all in advance.

1. The gearbox is essentially the same. I don't know about the ratios, but they are swappable. I am pretty sure that the ATESSA system on the GTS4 is not as clever as the GTR's though.

2. HICAS is 4 wheel steering. As such, it is no different on a GTS4 than on any other R32. The reservoir is the power steering reservoir.

If, however, you mean ATTESSA reservoir, then yes, it's in the boot.

3. No. Diff is same as GTSt. that includes 5 bolt driveshafts and normal uni joint tailshaft, rather than GTR's CV type tailshaft and 6 bolt driveshafts.

4. Under the parcel shelf. Not the HICAS computer which is also there.

5. Google it.

6. Depends on how well the retrofit has been done, with respect to wiring and so on.

7. Not sure.

8. Shouldn't be.

9. Nup.

10. Dunno. Possibly.

for the r32 gts4 the hubs(spline), half shafts, diff and tails shaft are all to suit/swap-able with a gtr

much like the gearbox i'd say the ratio is different tho

1. Does a GTS4 run the same gearbox and front axles etc as a GTR?

Probably not as strong as a GT-R, but can't say for sure. After all, it's only designed to handle a RB20DET.

2. Where is the HICAS pump and reservoir, in the boot on the right side?

HICAS pump / reservoir is the same as the P/S pump /reservoir. R32 HICAS system is hydraulic, later models are electric.

The reservoir in the boot is the ATTESSA fluid reservoir.

3. Is the rear diff the same in a GTS4 to a GTR? Ratio, strength, LSD?

Both are R200 diffs. There the similarities end. GTS4 is a viscous LSD, 4.375 ratio. GT-R is a mechanical LSD, 4.111 ratio. (Stagea, as in mine, is 4.083, open?)

4. Where is the ATTESA system ECU? Wiring and controlling components?

In the boot, under the rear parcel shelf. Inputs come from:

ABS wheel sensors (wheel slip)

Throttle

G-sensors located under the centre console

5. How does ATTESA system work, does it only send power to the front wheel when the rears start to slip? What is ETS?

see 4. Also, search this site.

6. How do you know if the system still works, like if fuse is blown or wiring is dodgy how can you tell? Does the gauge that says front torque split only read something if the system works?

Warning light in the dash will come on in any sort of error condition.

7. Where is the high pressure pump that makes the front wheels engage power?

From memory, it hangs off the rear diff

8. Is it common for 4th gear to crunch in GTS4 or GTR gearbox?

Not normally, not in my case. Possibly a sign of a mistreated box.

9. Is it worth putting in a GTR rear end in a RB25'd R32 GTS4, what are the advantages?

I haven't done anything like that in mine, which was dynoed to 180kW at all four.

10. If ABS has been removed, does it change how the ATTESA system works?

Depends. If you leave the ABS sensors, then ATTESSA should still work.

The advantage of putting a GTR rear end would be a proper mechanical LSD. It would be 4.1:1 (higher geared) so that could be a good or a bad thing... and the disadvantage would be that you would need to change the front diff to a 4.1:1 as well.

Thanks heaps for the heads up guys. I used the F* out of google images and I now sorta get whats going on with Attesa (4th year engineering student btw)

A: Do GTR's have ATTESSA-ETS, the more advanced version?

B: Which ecu under parcel shelf is Attesa and which is Hicas?

C: Do the attesa systems mess up much?

D: If you have a 300+rwhp GTS4 and you pull the 4wd fuse, will it wheelspin in 2nd when coming onto boost? And have way more traction if attessa works?

Cheers again

A. http://en.wikipedia.org/wiki/ATTESA-ETS

B. Looks like http://i106.photobucket.com/albums/m263/bades13/IMG_4194.jpg and http://i106.photobucket.com/albums/m263/bades13/IMG_4195.jpg

HICAS has two plugs like http://i106.photobucket.com/albums/m263/bades13/IMG_4196.jpg

Side by side..... http://i106.photobucket.com/albums/m263/bades13/IMG_4199.jpg

C. They have their failures. Poor maintenance is the main killer.

D. I'd be upset if you couldn't spin it up changing into 3rd, and like of course it will have more traction in AWD.

gts4 and gtr have the SAME gearbox as i have opened both side by side. your 4th gear is crunching cause your box has either been flogged or poorly maintained or both, as there are 3 small stainless clips in the synchro of 4th gear to allow it too work, albeit it a poor design and no nissan doesn't make them anymore, get a re coed box for like 800 somewhere or get and r33 gtr s2 box that can handle like 700hp. the awd system is hydraulic the front wheels will grip once the system realizes there is slip in the rear, you can hook up a kill switch to the fuse to alternate between 2wd and awd for some fun and it doesn't cause any issues, just make sure to stop before switching it over, also with these cars and other gtrs, wrx, evos, etc make sure that all 4 tyres share the same profile and rim size as having different sizes can and eventually will destroy your diffs. there is no need to change the diff out off a gts4 they are strong as and have seen 9 sec pass on many cars from japan, just look after it they are also known to handle 800hp plus with the right care and driving style. the cars are beautiful i will never sell mine i just spend 20k on the engine now is rb30. also your front suspension is GTST NOT GTR don't let people tell you it is because the strut end has a different fitting. also be careful replacing the ecu with another r32 ecu the gts4 has a fit if you put in a gtst not a gts4 one, f**ks me why. Honestly i would ditch the rb25 and get an rb26, if i where in your shoes and not have the money i did to throw at this thing. any other advise i can think of with these cars i will send your way when i can.

Thanks for the replies guys. It really helped with my car.

I have a new question about GTS4's.

> Does the R32 GTR diff fit straight into a GTS4? Front and Rear, or are the housings difference size/shape/bolt pattern?

> Are the diff ratio's different?

> Are R32 GTR diffs the same ratio, like all only 4.1?

>If my rear diff in GTS4 has loads of backlash and I want to put in a better one, should I just get a 1.5 or 2 way LSD with correct diff ratio to match for rear. Rather than getting R32 GTR front and rear diffs as front diff install is engine out job.

No-one ever (correctly) said that GTS4 have GTR suspension. What they do have is GTR front and GTSt rear.

Other way round - rears are the same as GT-R. It appears that all models have the same style fronts.

I found if you ask for GT-R suspension components, you get the right stuff for the GTS4 (at least in R32s).

>>>>>>>>>NEW QUESTION:

Will a R32 GTR front sway bar fit a R32 GTS4?
Found this thread: http://www.skylinesaustralia.com/forums/topic/283424-gtr-r32-front-sway-bars-suit-what-other-vehicles/

Though I unbolted the GTS4 one and put it next to a GTR one and the GTR one bends out 40mm on each side, so it doesnt look like it will fit.

Any ideas?

      Thanks for all the replies fellas. Gonna finish putting it back together and see how it handles the set up. If it starts pinging it’ll be parked.

      J50 clock date suddenly reset to January 1

      By suko · Posted

      Well, I can recommend the partial AV system translation CD I ordered from Car Audio Workshop in NZ. Whilst it didn't address the date issue, it has conveniently translated on-screen menu items into English, and now allows the GPS-received time to be offset in hours rather than minutes, so I can display Eastern Australian time accurately ( and bump it by another hour when daylight savings starts ).

      I'd be curious to hear more. Otherwise, have you driven a modern x-trail? I wonder how it compares. Here in Australia they are/were popular for rentals and fleet vehicles. I have been in some and my impression was they are bad. But, this may have been very different in the 2000s at a good trim level. Twenty years is plenty of time to make the model worse. I do very much agree with the 2 silver cars in the garage approach. But, not driving because it's too hot would not leave a lot of time in the year for many Australians. I don't think you need to worry too much unless the car has actual issues with overheating.

      By BaronOBeefdip · Posted

      Back again. I returned to Japan in Jul/Aug to spend time with the car on my birthday and remind myself what all the sacrifice and compromise is for. It happened to line up with the monthly morning meet in Okutama, which I have been wanting to go to for a long time. It's a unique event at a unique spot with really rare, interesting, and quirky cars. It's where all the oldheads and OGs gather. The nighttime scene at DKF certainly has its place and should be experienced if you're into cars, but there's too much bad attention and negativity around it now. IMO the better time is Sunday morning at DKF or Okutama; it's more chill and relaxed. I'm glad I was finally able to go, but not sure it's worth the drive from all the way from Nagoya immediately the day before, unless I was already staying in Tokyo for the days right before the meet, because you have to wake up quite early to make it in time. Funnily enough though I didn't drive the car all that much this trip because it was just too damn hot. While there were zero issues and running temps were nominal and the A/C was strong, RBs already run crazy hot as it is. Sure, it took it all like a champ but something about driving these cars in the ridiculous heat/humidity bothers me and makes me feel like I'm asking too much of it. I'm just me being weird and treating the car like a living thing with feelings; I'm mechanically sympathetic to a fault. Instead I was mainly driving something else around - a KX4(silver) 2001 X-Trail GT, that I acquired in May. There's a few different flavors to choose from with Xs, but visually it's the Nissan version of the Honda CR-V. Mechanically it's a whole different story as this, being the top-trim GT, has an SR20VET mated to a four-speed auto and full-time AWD! It was a very affordable buy in exceptional condition inside and out, with very low mileage...only 48k kms. Most likely it was owned by an older person who kept it garaged and well-maintained, so I'm really happy with how it all worked out. It literally needs zero attention at the moment, albeit except for some minor visual touch-ups. I wanted something quirky, interesting, and practical and for sure it handily delivers on all three of those aspects. I was immediately able to utilize the cargo and passenger capacity to its full extent. It's a lot of fun to drive and is quite punchy through 1st and 2nd. It's very unassuming -in the twisty bits it's a lot more composed than one would think at a glance- and it'll be even better once I get better tires on it(yes, it's an SUV but still a little boat-y for my liking). So...now I have two golden-era Nissans in silver. One sports car and one that does everything else; the perfect two-car solution I think👍 The rest of the trip...I was able to turn my stressed brain off and enjoy it, although I didn't quite get to do as much as I thought. I did some interesting things, met some interesting people, and happened into some interesting situations however, that's all for another post though only if people really want to know. Project-wise, I went back to Mine's again to discuss more plans and am hoping to wrap that up real soon; keep watching this space if that interests you. Additionally, while working in the tormenting sweatbox that is the warehouse, I was able to organize most of the myriad of parts that my friend is storing for me along with the cars, and the 34 has a nice little spot carved out for it: And since it can get so stupid hot in there, that made it all the more easy -after I was standing there looking at the car and said 'f**k it'- to finally remove all the damn gauges that have mostly been an eyesore all this time. Huzzah. The heat basically makes the adhesive backing on the gauge mounts more pliable to work with, so it was far less stressful getting this done. I didn't fully clean it up or chase the wiring though; that will happen once I have the car in closer possession. Another major reason to remove all that stuff is to give people less reasons to get in my car and steal s**t while it's being exported/imported when/if the time comes, which leads us to my next point... ...and that is even though it's time in Japan is technically almost up since it's a November car and the X would be coming in March, I'm still not entirely sure where my life and career is headed; I don't really know what the future looks like and where I'm going to end up. I feel there's a great deal of uncertainty with me and as a result of that, it feels like I'm at a crossroads moreso now than any point in my life thus far and there are some choices I need to make. Yes, I've had some years to consider things and prepare myself, however too much has happened in that time to maintain confidence and everything feels so up in the air; tenuous one might say. Simply put, there's just too much nonsense going on right now from multiple vectors. Admittedly, I'm struggling to stay in the game and keep my eyes on the prize. So much so in fact, that very recently I came the closest I ever have before to calling it quits outright; selling everything and moving on and not looking back. The astute among you will pick up on key subtext within this paragraph. In the meantime I've still managed to slowly acquire some final bits for the car, but it feels nice knowing there's not much left to get and I'm almost across that finish line; I have almost everything I'll ever want for my interpretation and expression on what it is I think an R34 should be. 'til later.
