I have seen a car in japan that had R34 attesa and ABS fitted (along with a 34 engine and 6 speed too).

if I was going to do it I would skip the 33 and go straight for 34 if at all possible.

I heard ages ago that you could just swap the controllers, did a 1 minute google and came up with;

http://www.gtr.co.uk/forum/upload/6095-r32...controller.html

which refers to this

http://www.carsurvey.org/review_19225.html

Which says "Unless you know what you're doing you'll be better off with an R33 or R34, but for the ultimate in more than one sense of the word, an early R32 is hard to beat.

Handling can be subdued considerably by swapping in the ATTESSA-ETS AWD controller unit from R34, which pretty much makes the car behave like its newer counterparts."

I just ended up getting the cheapo ebay attessa tweaker, and it worked so well i just left it at that. The plugs are different on the attessa units, so its more than just a simple brain swap. No idea how much more.

They work well yes, but you're only ever going to get the system to operate as fast as it's weakest link.

I think it could be worthwhile, I am sure someone has done it.

Just need to do some dredging.

It's funny for how widespread the internet is there is still alot that only exists in the real world and I'm ok with that I think.

For me, i'd want to have some evidence it will make a non-trivial improvement over a tweaked standard system for the effort to be worth it.

But you may just want to satisfy your curiosity and try it!

Driving an R33 GT-R and 33 Back to back clearly shows the worthiness of the AWD upgrade I think.

ETS-PRO while good like the Ruzic unit is still not going to the root issue which is the preload, the speed at which the system operates and of course the vast increase in sample rate.

ETS-Pro maintains preload, the R32 and R33 system are same operating speed (pump gaining and losing pressure) and it has a brand new ECU with much faster sample rates?

I guess you meant R32 and R33 GTRs? If so, thats pretty obvious and therefore not so interesting.

IMO what is more interesting would be comparing an R32GTR+attessa tweaker to an R33GTR without a tweaker.

I'm assuming that the change in front/rear bias as the system evolved is a much more significant affect than things like the ECUs sample/clock rates. It is an assumption tho. Would be interesting to KNOW. Bang for buck and ease of installation the tweaker will be miles ahead.

      R33 GTR running -9 with no tune

      By joshuaho96 · Posted

      Yeah I suspect even if you hold airmass per cycle/cylinder constant if you get too far away from stock you're still going to have problems running the factory tune within the bounds of the factory load scale. Cams, different displacement/rod ratio, etc. I'm just lucky that the GTIII-SS with wastegate boost + CA compliance cats is pretty much equivalent to stock turbos. When I have actual space I can finally get it tuned and modify the fuel system for flex fuel to 100% handle any detonation concerns when cranking the boost to whatever those dinky turbos can put out.

      I would say no, why, because my daughter, who also lives in Goulburn, hasn't recommended us going there Pity, as we miss all the German joints around in Sydney, actually, the restaurants are the only thing I really miss about Sydney, and a special mention to Ishibanboshi at Bondi Junction, their Kara-age Don is heart cloggingly deliciousness (always added a special boiled egg...or 2) 😋

      Does that German restaurant still exist in the old place out the NW end of Goulburn? When I say "out the NW end of"...I am really being vague. It was 1997 when I was last there, and the only point of reference I can recall is that it was on the opposite side of the main drag from the big merino. And when I say "opposite side of the main drag", I don't mean "on the main drag". It was either a couple of streets back from there, or might have even been out in the sticks a bit further. Was an old farm building or mill or somesuch. And when I say "the big merino" I might actually be thinking of a completely different part of town, because I just looked on maps and the big bugger is not where I remembered him to be! The food was good, consisting largely of various German mystery-meat sausage/loaf things and kartofflen.

      So while the second sentence is completely correct and the whole point of the conversation, the first sentence bears consideration. If this bloke is just hoping to throw big turbos on and drive it around, because there are no helpful facilities at all in his tropical paradise** then he likely has zero chance of even knowing what the TP is on the last column in the stock maps, let alone know whether the ECU is operating anywhere near it or past it. So the point is very very moot. And, per what I said before, at stock boost on those turbos, you may well be off the end of the map. **I'm just back from Vanuatu, so I know exactly what small Pacific nations can be like wrt paradise without requisite facilities. But it's not even that simple. I put a high flow on my car and had to drive it around without a proper tune because of the lack of opportunity*** to put the bigger AFM and injectors into it to allow it to be tuned. I had to turn the boost down to less than I had before, and back off the boost controller's ramp, because it was exploring parts of the map that it didn't drive in before, and really couldn't access for tuning on the dyno either, and so was pinging. It was still well within the last column, because when I first**** set up the Nistune on the Neo I rescaled all axes of the maps to give some more space to explore. ***Family dyno was broken ****This was 13 years ago, and the TIM thing wasn't a thing then and so TP would definitely grow when pushing past the stock tune's limits.

      Squeaking clutch/throw out bearing

      By joshuaho96 · Posted

      Yep, this bit another local owner. I caught it before putting the transmission back into the car, what I noticed was the pressure plate fingers weren't flat and even. It's more obvious with the pull style clutch because the throwout bearing ring was visibly not flat once everything is put together. Nismo should really update their instructions to call out this specific detail. I'm not even sure the clutch as-shipped orients everything properly.
