Are You Cracking Dba Rotors?
djr81 replied to Roy's topic in Suspension, braking, tyres and drivetrain
To whom did you send your enquiry? 345*32 - for the Evos. No idea what the hat offset is, however. http://www.project-mu.co.jp/e/product/caliper_R6.html -

Not sure if it helps but Project Mu do aftermarket sizes. 355 * 32 among them. -

R32 Gtr Brake Upgrade Advice
djr81 replied to LotusGTR's topic in Suspension, braking, tyres and drivetrain
As long as the piston area of the new calipers is similar to those of your current set up the ABS will cope. The 4wd system doesn't care. If you use your car on the track (Properly) chances are you will crack the discs at some stage. Best bet is to select rotors to avoid this problem as much as possible. If you don't then there is no point spending large on brakes. Look for the thread on this very issue and get busy with the paper & scissors. Ask questions of the vendor. Then you will get the usual blandishments that are completely meaningless. They all say they work beautifully but recommend all sorts of different rotor diameters & piston areas. Make of that what you will. The booster uses vacuum to reduce pedal effort. By lines I assume you mean braided hoses. These swell less when you brake hard than old rubber alternatives hence less pedal travel is wasted. -
Relocating Battery To Boot - Battery Mount
djr81 replied to Scooby's topic in Engines & Forced Induction
My battery charger won't charge a completely flat dry cell. It just sees an open circuit & shuts down. So I just borrow the neighbours skanky old one which isn't clever enough to care. Works fine. -
Ah, um, sorry. Me neither. Saturdays at work suck too. There was a good story from the VK Commodores at Spa in 1986. There is a book about it - Brock Moffat on the road to Spa.

I would disagree with that to an extent. Basically whetever is remaining of the road cars in the V8 is there merely to make them look a little bit like what you can buy down the dealership. For instance the road car chassis not longer has any load bearing contribution - it is rivetted to the spaceframe rather than welded. Both the FG & the VE have different wheelbases & trackwidths than the road cars. The front quarter panels are fibreglass & not even close to the factory dimensions, rear door skins on the Commodores are now fibreglass too. The suspension (paticularly the rear, live axle) was originally included because the VP & EB Falcons had live axles but mostly because they were cheap. Struts were used in the Commodores front ends, wishbones in the Falcons. Obviously now both front & rear V8 suspension packages bear no resemblance to anything leaving the factory. My point is that is obviously difficult to drive the V8's well. You can see this by how many people struggle when they get into the series proper & by how many mistakes the development series drivers routinely make. I don't think that the difficulties are derived from the road cars - there isn't enough of them left to matter. I think it is a result of the regulations. I would reckon any Group A car is by definition, more compromised by its factory origins than a V8.

Relocating Battery To Boot - Battery Mount
djr81 replied to Scooby's topic in Engines & Forced Induction
Just get a dry cell battery, a box & install it in the boot. The good things about doing this are: Moves weight tot he rear. Frees up room under the bonnet ( I relocated the carbon canister for more air to the filters) Bad thing is if you need to carry stuff you have alot less room. -
Gtr Diff Nismo 1.5 Or 2.0 Way?
djr81 replied to Travis Trayhern's topic in Suspension, braking, tyres and drivetrain
Heal & toe. Sort of. It will stop the diff locking on clutch release, but probably not as the engine drops revs by itself. Nismo do upgrade kits for the stock diffs as well as the stuff listed so far. There is another thread not dissimilar to this one which is worth looking through. -
Gtr Diff Nismo 1.5 Or 2.0 Way?
djr81 replied to Travis Trayhern's topic in Suspension, braking, tyres and drivetrain
The two way will lock when you have torque transmitted via the engine on the over run, ie when the motor is slowing the car down. This commonly occurs on corner entry and yes it makes the back end reluctant to turn = push understeer. Check the Nismo site as the TT version for the GT-R's is only a new addition. Rather than just believe the website send them (Or another of the importers...) an email to check. They should be readilly available in Australia. The difference in the two versions is basically the ramp angle. TT Pro is more gentle and is better if you want to use it on the road. Don't use a 2 way on the street. -
R32 Master Cylinder Changeout
djr81 replied to djr81's topic in Suspension, braking, tyres and drivetrain
Closest I found was this. It is from an R34 so they do fit, but it was done in Japan & the bloke concerned obviously couldn't say how much messing around it required. http://www.skylinesaustralia.com/forums/Eo...;hl=rockhampton -
Gtr Diff Nismo 1.5 Or 2.0 Way?
djr81 replied to Travis Trayhern's topic in Suspension, braking, tyres and drivetrain
No a 2 way is not for dragging. Which is not to say you can't succesfully use one. You need to understand what the 1 way, 2 way means. Best off doing a search, but roughly they work as follows. Basically they are mechanical limited slip differential where the engine torque helps clamp the friction plates in the diff. A one way only does so under acceleration. A two way acts under acceleration but also on the over run. Hence it is useless for drag racing. A one & a half way is supposedly in between but in reality the ramp angles on the over run on the Nismo diff are square so it is a bit of marketing bullshit. Remember that the pre-load gives you an LSD function without any engine torque. The more aggressive of the Nismo LSDs are a nasty thing on the road. You cannot gently turn a corner with any engine torque without the diff locking/clunking. Look to the pro lsd tt version if you use the thing on the road. -
Gtr Diff Nismo 1.5 Or 2.0 Way?
djr81 replied to Travis Trayhern's topic in Suspension, braking, tyres and drivetrain
The 1.5 way diff isn't really a 1.5 way, but anyway. You wont need a 2 way for a hill climb, in fact you would be better off without it. As for track work a 1.5 is better anyway. Remember the Nismo diffs have adjustable presets. Check the nismo website www.nismo.co.jp -
Engine failure is not uncommon on GT-R's. For $10k it may well be worth looking at.

This proves my suspicion that, oh you work it out for yourselves.... http://www.carcentral.com.au/20080506589/m...-indy-2005.html

Went to Albany on the weekend...

Do you have the manual. If so it will have a procedure. If not say so & someone will dredge the relevant bits up.
-
For the record, this is the approved method.

The colour scheme is a rip off of the one Nissan ran in 1991.

As had been suggested a number of times the list of things to do are: Don't use DBA 4000 series rotors, find something else. I would suggest Project Mu as they are getting more & more competitive on price. A decent pad is a Ferodo DS2500. Get them from a proper brake shop & not somewhere like Repco who will just fk you about and confuse themselves. There are a number of other pads sabout which may suit you. Front set is $300 approx. Get some new fluid. Motul RBF 660 is good/cheap(ish). Braided lines will help wil pedal feel but aren't strictly necessary. Make sure you get ADR compliant ones. What will help is a master cylinder stopper. Cusco do a nice one. Lastly the Brembo callipers fitted to Skyline are poverty pack rubbish & in no way worth the kinds of money people ask for them. That is by way of general comment.

Importing From Europe/uk
djr81 replied to Stoney85's topic in Importing, Compliance, Modification Laws & Regulations
If you are going to bother bringing something back then make it something that was never sold here. Eg anything with Cosworth in the name, a Lancia Delta Integrale, an early BMW M3 (LHD so not sure if you can rego them outside WA) Don't bother with common or garden variety stuff. -
Yes you have an oil cooler/warmer. There is a feed that takes water from the radiator & via a small heat exchanger helps warm/cool your oil. The exchanger is just behind the oil filter. HICAS = marketing wank. Mine was an R32 so removing it saved alot of weight & stopped me from scaring myself silly. Personally I hate it but alot of people don't mind it. If you are aware of its function ie you can feel it when you are driving then you will be in a position to decide. If you can't feel it working then there is no point you removing it. The RB26 will be happy on 14#, in fact there is a good argument to say that is what Nissan really had in mind when they designed them. The fuel pump, regulator & coil packs will all be happy. The only caveat is if they are already stuffed replace them. Lastly dont know where you are but the stock Nissan box is fine & may stop you getting err, fined.
-
They do, but typically they are not set up with any useful amount of pre tension hence don't actually function as an LSd very well. Certainly not on a circuit with proper tyres & a good amount of rwhp.

You haven't said what tyres you are running although I would guess from the desciption it was street tyres. The fundamental question you need to ask yourself is do you wish to continue running on those tyres or get something more suitable. The reason it is such an important question is that the setup options are, to a large degree, dictated by what rubber you have. What sort of light mods? 1. Better tyres will be # 1 with a bullet. 2. Stiffer sway bars front and rear. 3. More -ve camber at the front. 4. Lose the HICAS 5. Stiffer suspension. 6. Get some half decent brake pads. 7. Increase the boost to 14#. 8. Install a better rear LSD. You may have done some of these things. For reliability an oil cooler is a must. Also overfill the motor with oil. For better track times spend some time with an instructor. This would be my # 1 go fast "modification".
