Hi Guys,

Im about to do some serious upgrades to my s15 aiming at atleast 250rwkw and i know that my 6sp box will turn to cactus as soon as this is done and im too poor to go par/dogbox and i dont want to throw away 1300 on a new clutch/fly to go on the 6sp and then get a new box anyway..

i dont really know that much about skylines but i hear that the series 2 r33 box is good for around 700hp which seems pretty much ideal. fyi the clutch im getting is made by orc

so the questions that i have are:

are there any 6sp rwd gearboxes for skylines?

r33 series 2 vs r34 neo? which one is better etc..

upon buying the gearbox what else will i require? i know ill need the housing modified and a new tailshaft

is there anything i should look out for while im doing this?

how will this impact the s15 diff?

sorry for all the questions

many thanks

no

34 is reportedly better and stronger , but rarer and more expensive .

is there anything i should look out for while im doing this?

they are hard to find cheap or they are expensive when found . obviously try and get a good condition low km one

how will this impact the s15 diff?

should be fine

thanks a bunch for the info arkon

question on the 34box- how much is expensive?

and also is it just the housing and tailshaft that needs to be modified?

with the housing is that something that can only be custom made and not something that i can buyas a part?

recomended places in vic to do such things?

will need to get gear stick so might as well get a short shifter.

modified housing. maybe a r33s2 tailshaft or vl depending on availability and custom cross members.

can anyone in melb recommend a good place to get this done?

and do they have anymore ?

i would just get that box or another one like it . the r33 box is a really nice gb . its an immesurable improvement on your s15 one .

jspec racing hehehe

anyways..

I have a R34 GTT Gearbox, picked it up for $1500, with 17,000kms on it, i thrash the absolute crap out of my car, and this box loves it (200rwkw)

if you can afford $3,000 for a new one, get a gearset for your s15 box, would be the same price or around that and less f**king around.

just an idea

      Stock rb25det neo questions

      By Wazmond · Posted

      Hows your intake piping? Are you still running stock? Having in the stock AFM position would mean, if the BOV was shut/venting out, it'd create the almost stalling kind of effect right // "the rich pulse behaviour" due to MAF thinking air is flowing ? But this would be better than having the bov in the stock position + MAF on/just before cross over piping right?

      Essentially, yes. Although I wouldn't put the AFM on the crossover pipe. I'd want to put it into what amounts to the correct size tube, which is more easily done in the intercooler pipework. I bought a mount tube for card stile AFM that replaces the stock AFM - although being a cheap AliExpress knockoff, it had not flange and I had to make and weld my own. But it is the same length and diameter as the stock RB AFM, goes on my airbox, etc etc. I don't have a sick enough rig to warrant anything different, and the swap will take 5 minutes (when I finally get around to it and the injectors & the dyno tune).

      So to summarise, the best thing to do is to move recirc to between turbo and IC, and maf on the crossover pipe. Meaning I'd need a recirc flange, drill a hole in the piping on turbo outlet area. And drill hole on crossover to fit/weld maf sensor? Either that or put the MAF on the turbo inlet right?  Is an aftermarket recirc/blowoff valve recommended? Do currently have family in Japan so could probably bring something back with maybe a cheeky lil SuperAutobacs run?

      Lets play a game - What is causing my oil consumption?

      By tsuokun · Posted

      Yep, so far most have said that it looks like corrosion on the wall from piston not moving. Which then has probably damaged the oil rings and caused those vertical marks. The longest the engine was still after the rebuild, was the winter of 2018 - 2019, plus the boat trip to Japan. When I shipped the car, it had normal gas in the tank but before that winter pause, it had E85 in tank.  In any case, even if either one of those was the cause, it happened close to 6 years ago and the car has been driven something like 30 000kms after the fact. Again, apart from the plugs and the dip stick, there is nothing in the way the car runs that would indicate what has been going on in the engine. I am going to consult a shop and ask their opinion, what would be the best approach. I do have some access to a garage I could use to diagnose further myself, but time is very restrictive. Might end up buying another engine that could be used while this one is being remedied. Without pulling the head, it will be impossible to find out if it needs another bore, but here's to hoping a hone would suffice.  Goddamnit, I would really have preferred this not happening.

      Got this r31 silhouette flood car to rebuild.

      By 25RBGT · Posted

      Boot is going to be replaced eventually. I just wire brushed what I could and rust converted. Then painted in rust kill primer. the spoiler also got repainted and plugs replaced on the ends. The under side of the bonnet is going to be black also, currently white. But red on the top side, same colour code as the silo to begin.
