you'll want to swap the diffs back if your after more acceleration.

auto- 3.9-1

Manual - 3.7-1

or, if you can find them, pintara pinion and crown wheel for 4.1-1 ratio

and with the speedo issue, the 31s and 33s both have electronic speedos. you need a Speedo Interceptor (jaycar sell them) and the just adjust it using a navman or something.

will get the pics soon. all depends on if i can sum up some motivation and walk downstairs, move the car, jack it up and then roll around in crap.

as far as i know oil lines run from turbo to engine with a oil pump to assist.

i have a separate oil cooler for the trans.

i've sourced a r31 skyline diff with lsd. and i believe thats a 4.11? and i think the pinny's have 4.1

i could be wrong. and just so i know, the bigger the ratio the better acceleration, ie 4.11 is better then 3.7?

cheers

4.11 will get you better take off and higher cruising rpm's, 3.7 will give you better top speed and lower cruising rpm's

ah thank you. i'm looking for take off as i care not for my fuel consumption.

does any one have any thoughts on installing an r33 auto gearbox. i was put under the impression today that they'll handle more power then an r33 manual box.

cheers

Manual is much stronger till you spend a few Grand on the auto, would definately be stronger than a 31 auto tho

If i was you i would try to keep it auto, a friend had a 5 speed turbo 31 and he changed to an auto with a hi stall and the thing was awesome, there not the best handling things till you start putting S13 struts and brakes on em so you would be better of with the auto for straight line speed and a small amount of twisty action.

yeah i want to keep it auto. already have a stall convertor. My next step is the r33 auto box and lsd. Then a full s13 suspension conversion along with break upgrade (something like r33gtr or gtst breaks, the four piston ones) and fatter tires with good tires. then after that more engine performance.

best way to tell what ratio you have is to pull the back cover off the diff before you install it and see whats stamped on the crownwheel. i think 4.11s are 37:9

manual 31 skylines are 3.7 factory (except gts)

auto 31 skylines are 3.9 factory

and all 31 pintaras are 4.11 factory, also 25 spline centre and axles instead of the 28 spline the skylines got.

and only the silo's and gts's came with lsd's, shit ones at that

im getting the lsd for about 70 big ones so im not fussed, its gotta be better then what i got. but i will have a look at it before i buy it. what tools are needed to remover the back cover? and will shit, ie oil, pour out?

and i'm looking for 37:9 to be stamped?

just a socket, ratchet and possibly a flathead screwdriver to pry it off. cant remember what size bolts they are, probably 12 or 14mm.

unless its been drained it'll be full of oil, if you sit the diff so the back cover is pointing up then it wont piss out. yer your looking for a ratio stamped on it like 37:9, or you can count the teeth on the crownwheel and the teeth on the pinion and figure it out that way.

and only the silo's and gts's came with lsd's, shit ones at that

Holdens are much the same of that era, most VL and R31 ppl dont bother trying to chase an lsd because the power of the turbo will kill it any way, my mates had a mini spool (locked) diff, was easy to drive in wet and dry and mega predictable when having some fun.

cheers. Disregarding money then what would be the best diff to get then? and then regarding money, what would be the best diff to get?

and here's some pictures for ya's:

There ya go. Threw in the engine bay pics so ya can let me know how sleeper it looks. I'm thinking if a cop or someone uneducated were to look at that at night they wouldn't no any better?

cheers and once again sorry for the wait.

I think you have more of a chance of being defected on suspicion, after all the intake pipe is coming from where it normally would if it had a turbo on it, and if you get some one who decides to trace the pipe (all cops carry torch's day and night) then your getting an epa, to make it stealth you really needed to tell your mechanic to put in the extra work when he put it in, about the only way you could possibly hide it, atleast partially, is to chrome the intake pipe to about 3/4 of the way down the engine bay and from there on paint it matt black, get a pod filter and make enough of a hole down the middle that you can slide it over the the pipe far enough that the chrome ends under the pod filter, hopefully that way all they see is a chrome pipe with a pod filter on the end of it and the rest of the matt black painted pipe will not catch there eye past the chrome.

    • Yeah i found that alot of parts can be wrong or "very" hard to get the real right one. I already bought some brakes years ago on me "old" GT calipers and they were wrong too 😄  I told them too. Even send them pictures...but they said "EBC catalogue has them on my car... So i dont know what their answer will be. I call monday them and let them know that they are really not on my car. If they were they would be already on a car...
    • Welcome to Skyline ownership. Yes, it is entirely possible parts websites get things wrong. There's a whole world of inaccuracies out there when it comes to R34 stuff (and probably 33 and 32). Lots of things that are 'just bolt on, entirely interchangable' aren't. Even between S1 and S2 R34's. Yes they have a GTT item supposedly being 296mm. This is incorrect. I would call whoever you got them from and return them and let them know the GTT actually uses 310mm rotors. Depending on where you got them from your experience and success will obviously vary.
    • Hi...a bit a "development" on the brakes. I spoke to the guys where i get brakes from...and they are saying that 296mm EBC are for R34 GT-T. I then went to their site: https://www.ebcbrakes.com/vehicle/uk-row/NISSAN/Skyline (R34)/ and search for my car(R34 GT 1998 - it has GTT brakes) and it show me this USR1229 number and they are rly 296mm rotors... So now iam rly confused... The rotors i have now on the car are 310mm asi shown... So where is the problem? Does the whole EBC got it wrong or my calipers are just...idk know what?  
    • Oh What the hell, I used to get a "are you sure you want to reply, this thread is XX months old" message. Maybe a software update remove that. My bad.
    • This is a recipe for disaster* Note: Disaster is relative. The thing that often gets lost in threads like this is what is considered acceptable poke and compromise between what one person considers 'good' looks and what someone else does. The quoted specs would sit absurdly outside the guards with the spacers mentioned and need  REALLY thin tyres and a LOT of camber AND rolling the guards to fit. Some people love this. Some people consider this a ruined car. One thing is for certain though, rolling the guards is pretty much mandatory for any 'good' fitment (of either variety). It is often the difference between any fitment remotely close to the guards. "Not to mention the rears were like a mm from hitting the coilovers." I have a question though - This spec is VERY close to what I was planning to buy relative to the inboard suspension - I have an offset measuring tool on the way to confirm it. When you say "like a mm" do you mean literally 1mm? Or 2mm? Cause that's enough clearance for me in the rear :p I actually found the more limiting factor ISNT the coilover but the actual suspension arms. Did you take a look at how close those were?
