Hey all

looking at diffs for my r33 gtst series 2 track car.

The car is mainly for 200 meter runs. But also mucking around at drift stuff.

So im after grip and heavy acceleration!

Whats the ratio of the standard diff?

What would you recommend 1.5, 2way etc?

And what ratios for flat out acceleration?

Plus strength

cheers

Yes keep the housing.

If you get a Cusco one you can adjust it all the way from 2 way to 1 way according to your preference but most people seem to go for Nismo. Or you can get a 2nd hand GTR diff but then you have to make changes to suit the 6 x 1 bolt pattern.

Hey guys had a 2-way in my 32 and kinda got over the clunks/jerks and now looking to put the power to both wheels in the 33..

I'm unsure what to do with a stock auto diff.. do I still have 1, 1.5 way options in the ratios the auto uses?

Also it will have a shift kitted box with 250+, so I'm guessing a shimmed diff wont like that power for long. Trying to maintain good drive aswell as being able to have both wheels putting power down.

1/4 mile and cruising only.

sounds like your ideal diff would be helical. But that's another kettle of fish finding one. They did come in late model R34 manual turbos but rare as f**king hens teeth and wreckers wouldn't know one if it hit them in the head.

/\ ive found a S15 helical 4.08, which is a swap over using s15 6-bolt shafts also..?

I did that to my R32. Put it into R32 housing with R33/4 4.11 gears and S14 half shafts and driveshafts. It's a real bitsa, but it works. The only downside will be if I start finding the strength limits of the 3x2 bolt CVs.

      Version 1 aluminium airbox is.......not acceptable No pics as I "didn't like the look.....alot" Even after all my "CAD", and measurements, the leg near the fusebox just didn't sit right as it ended up about 10mm long and made the angle of the dangle look wrong, the height was a little short as well, meh, I wasn't that confident that Version 1 was going to be an instant winner I might give Version 2 another go, there's plenty of aluminium at work, but, after having in on and off a few times, and laying in the old OEM airbox without the new pod filter and MAF, there may be an option to modify the OEM air box and still use the Autoexe front cover and filter.... maybe This >  Needs to fit in here, but using the panel, and not the pod, the MAF will need to fit in the airbox though> I'm thinking as the old OEM box and Autoexe cover that is sitting in the shed is just sitting around doing nothing, and they are relatively abundant and cheap to replace if I mess it up and need another, it may well fit with some modifications to how the Autoexe brackets mounts to the rad support, and some dremiling to move it get in there, should give me some more room for activities, as I don't want to move the MAF and affect the tune Sealing the hole it requires to stick it in the air box is simple, a tight fit and some pinch weld will seal it up tight  I am calling this a later problem though

      and it ends up being already priced in as though you're just on 91RON without any ethanol. Car will lose a bit of economy as the short and long term fuel trims bring down the AFR back to stoich or whatever it is for cruise/idle for the engine.

      Oh, you are right. But, in Australia E10 is based on 91RON fuel and ends up being 94RON. Hence it being the cheaper option for economy cars. The more performance oriented cars go for the 98RON fuel that has no ethanol mixed in. The only step up we have left then at some petrol stations is E85.

      There is a warning that "this thread is super old" but they ignore that anyway...

      With 10% Ethanol, we're talking 2-3% fuel consumption difference. The emissions reductions and octane boost in my opinion far outweigh this almost non existent loss.    My tanks sitting at 80%. Luckily that should go down fast as I'm on vacation again for the next two weeks.
