And here's where it gets funny. Just on the offchance that he has one of those chicken lips R34s with a helical LSD, then the jack it up and spin a wheel test will not prove that it is LSD. It will instead indicate that it is not LSD, even though it really has one.

But yes, unless someone has been completely retarded, then every turbo R34 has an LSD.

I always thought all R34 GT-T manuals (series 1 and 2) came with the helical torsen diff, and the auto's came with the VLSD's?

R34 GT-t S1 has a VLSD = gay

R34 GT-t S2 has a Helical = pretty damn awesome for a street car with mild power.

This attached brochure (third last page) says the manuals were helical and the auto's viscous. That being said, perhaps the NZ imports were all specified with the helical diffs.

No. Most of the manuals are viscous too. It doesn't even seem to be true that all the S2s have a helical, from what I've seen!

I know. I used to use that brochure as the basis for my belief along the same lines. But the sad reality seems to be different. I have secondhand knowledge of only 2 R34s with helical diffs. All the R34 diffs I've followed up for my own purposes have been viscous, regardless of whether they were 4.11 or 4.08.

Mine is a S2, pretty sure it has a helical diff in it. Built March 2001, factory manual etc

Is there any way of easily checking?

The back end sure feels better than the old viscous LSD in my 32, and hooks up as well as the 1.5 way mechanical diff I put in the 32 without the clunking around low speed corners.

You can feel the front end want to push straight if you are taking pretty constant corner and start to feed on the power, much like it did when I swapped the diff in the 32

The brochure linked is ONLY for s2 R34's.

S2 R34's are pretty rare to begin with. They were only made for like 6 months, Late 2000 to early 2001.

99% (no idea on the number) of R34's are S1's.

I've had both diffs (well, I had a S15 diff, but its the same center...) and I actually prefer the VLSD... when it's working as the one in my car was/is in good condition (for now).

The predictability was really quite noticeably better than the Helical diff, which likes to inside spin REAL easy, which isn't really a problem at 150rwkw with good tyres, but dial it up to 400 then try and take a corner under power and then you'll find the back end being nice and unpredictable which is quite undesirable.

I've got a r34 gtt series 2, but mine use to be a auto so the diff is a VLSD and its shit, single spinning for daysss..

I had a s15 1.5way kazz lsd i was going to fit but surprisingly its completely different. On the forum everyone says they are the same diff but NOOO..

The r34 gtt has 2 abs sensors, one on each side of the diff where the axels connect and its a short nose r200 diff housing.

The s15 has one abs sensor where the diff connects to the tail shaft hence it has a long nose housing...

SO dunno how people use s15 diffs in r34s... :verymad::verymad:

Also my car had S15 diff, and both driveshafts.

Also it was originally a N/A, so it didn't have the traction control sensors or HICAS to remove/deal with/keep working.

It also had the ABS computer from a S15 installed into it.

(it'd be far smarter to swap the center)

      Duncan's V37.......race car?

      Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!

      To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules

      Duncan's V37.......race car?

      By Duncan · Posted

      So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket

      As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year.

      I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
