Ok... done a search but cant seem to find a conclusive solution.

Ive let the tyres down to 25psi and that has marginally reduced it... but its still there and its really annoying (apart from damaging ur rear end).

Ive good pretty stiff suspension (tein HA) but apparently u can fix it if u put pineapples in...altho i cant understand y it would fix it coz pineapple would make it even stiffer.

Ne1 had any experiences with this or can reccommend a good place to take it to preferably on the south East side of Melbourne?

a great solution in drift pinapples.

we use them to soften the transition from grip to drift.

they effectively also eliminate tramp as a byproduct.

(if you dont know what i mean by drift pinapples, i mean solid mounting your rear cradle)

I'll be getting metal ones if I can find them because I plan to put them in as "All-Round" and therefore the normal ones wouldn't benefit me as my subframe bushes are probably stuffed after 15+ years of service.

But I guess if you're gonna set them up for "Drift" those yellow ones would serve fine.

Anyone know who sells alloy pineapples? Can't seem to find anyone with them. :D

there are different types of spacers...

the whiteline urethane (i think that's what they are made from) ones can be used to 'align' the subframe

the alloy ones don't align the subframe, you put one on top and one below the subframe and they squash the original bush - locking the subframe in place.

if you want to align the subframe go for the whiteline ones - they also have a pic on their website on how to install for grip / all round / drift.

they are all claimed to reduce or eliminate axel tramp, but tramp can also be caused by stuffed shocks.

(garage-13.com sells alloy pineapples)

one of thing that can often be mixed up as axle tramp, is tailshaft centre bearing movement causing the tailshaft to whip when taking off, we had this on our car & we had pineapples, thought it was a stuffed shock.

fitted new centre bearing & all good!!

may help cheers russ

Very interesting... whats a good test for this?

NV 101 a member on this forum sells pineapples, cnc machined alloy ones for $100 deliverd. DO NOT USE GARAGE 13! I REPEAT DO NOT!. a friend at work has waited 2months for some items from him (pineapples etc). he paid on order and they jst keep giving him the run around. ive bought 1 set off nv 101. great to deal with quick delivery, very happy :(

torque steer is due to unequal length driveshafts, as the longer shaft can flex more than the sorter driveshaft under high-powered acceleration

axle tramp is related to lack of compliance in suspension bushings and worn shocks/springs.

      Mistakes were made, my R34 Story

      ..this is the current state of that port. I appreciate the info help (and the link to the Earls thing @Duncan). Though going by that it seems like 1/4 then BSP'ing it and using a bush may work. I don't know where I'd be remote mounting the pressure sender... to... exactly. I assume the idea here is that any vibration is taken up by the semiflexible/flexible hose itself instead of it leveraging against the block directly. I want to believe a stronger, steel bush/adapter would work, but I don't know if that is engineeringly sound or just wishful thinking given the stupendous implications of a leak/failure in this spot. What are the real world risks of dissimilar metals here? It's a 6061 Aluminum block, and I'm talking brass or steel or SS adapters/things.

      And if you have to drill the oil block, then just drill it for 1/4" and tap it BSP and get a 1/8 to 1/4 BSP bush. The Nissan sender will go straight in and the bush will suit the newly tapped hole. And it will be real strong, to boot.

      No it doesn't. It just needs an ezy-out to pull that broken bit of alloy out of the hole and presto chango - it will be back to being a 1/8" hole tapped NPT. as per @MBS206 recco. That would be for making what you had in alloy, in steel. If you wanted to do just that instead of remote mounting like @Duncan and I have been pushing. A steel fitting would be unbreakable (compared to that tragically skinny little alloy adapter). But remote mounting would almost certainly be 10x better. Small engineering shops abound all over the place. A lathe and 10 minutes of time = 2x six packs.

      Ahh. Well the block damage is a problem, you really need to run a tap or thread chaser through it to see if the threads can be saved, but any chips are likely to be bottom end bound which is bad. Earls seem to have what you need if you want to stick with mounting direct on the block: https://rceperformance.com.au/parts/earls-straight-adapter-1-8-npt-male-to-1-8-bspt-female.html, but as I said above I'd recommend remote mounting the sender

      I'm not quite understanding or I'm missing steps here, (I appreciate people are trying to inform my brain but I am of the dumb, especially today) - All I want to do is mount the male BSPT of the OEM sender into the system somewhere without it snapping the adapter via vibration. The Nissan sender has a male 1/8 BSPT output. The block has a (very destroyed) 1/8 NPT input. I'm not really sure how a lathe assists with that, and also don't know anybody with a lathe, nor specifically what I would want to buy. I'm not really sure how adding additional adapters creates a better, more leak proof resilient seal here.
