Hi Guys,

Was just wondering I have been told that it's very easy to get a R34 GT-R 6spd Box to fit in a R32 GT-R with a RB26, and I was wondering if this is the case with an RB26/30 or if it requires a fair bit of mucking around.

Any information you guys could give me would be most appreciated, also would you say that the R34 GT-R box would be good for 450-500awkw or that would be a stretch?

Cheers

Nope wont hold the power reliably.

Was shown a gearset from the same 6 speed box the Supras use, gearset was about 50% wider than in the 34 box as used in the supras.

I was told there is somebody out there that can convert some of the wider gearsets from the supras into the R34 boxes but never asked further about it by the workshop.

That's really interesting. I've never heard that about the wider gears in the supra boxes. Good to know!

Saw it at Edge motorworks, Barry pulled out a Supra gearset and handed me a R34 one and the difrences were staggering.

One of the guys that work there mentioned they heard someone out there was manging to slip some of the Supra gearsets into 34 boxes, dont know which ones or who they were, i might ask next time im in there.

Please do, will be keen for the result

have lined up a 34 GTR box to go in my 32, would have been fine at the initial power levels. but now we are shooting for 700whp so i may encounter some issues

Does OS do a gearset for the getrag ?

I've looked at the PPG gearset for my getrag, $9,990 plus fitting and you have to have or get a getrag to fit it to, when for $16,000 you can get OS88, so by the time you buy a getrag and the gearset and have it fitted you would be better for paying the bit extra and get the OS88, or if you have one sell it

If you use the original Nissan 5sp, (FS5R30A) and get a ppg gear set, it will take a bit of abuse!

They're about $3200 for a gear set plus install and bearings etc. Lookup the ppg site, they have heaps of info on the stuff they sell.

No they are not $3200 for a ppg gear set..if they were everyone would have them.

A PPG gearbox will owe the the best part of 8-10k depending on what ratio's/billet mainshaft/forks etc you choose.

Wow have they gone up in price! That's what we paid for a set in our r33 drift car, and about $1100 on top for bearings and some bits from Nissan.

but this was about 2 years back.

      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.
