Sorry I don't know whether Whiteline have the R33GTST shocks revalved, they have a great shock dyno and are quite capable of specifying the correct valving for their springs. If the shock needs revalving then they would do it, if it doesn't then they won't. I have specified the valving for the Bilsteins that I am using, based on my own shock dyno tests. Because they need to have a window that is good for the springs on their own. Plus is good for the stabiliser bar rates if someone wants both springs and bars. That's the important thing with shocks, they have a window, not one single point at which they are "right". The spring and bar rates have to fit in that window, and that's the tricky bit, particularly when you add adjustable stabiliser bars into the equation. Height makes no difference to valving. cheers

Duncan does it again, finished 2nd at Wakefield Park in Race 1. GTR's 1st and 2nd. cheers

I think it will be ongoing, it depends on how many people want to join in. Plus I am going to expand it for more Skyline models, as I do the engineering on rates, settings and valving. cheers PS; you can buy it bit by bit of you want.

1. Yep, they have 6 cirlip grooves, 2 higher than standard and 3 lower than standard. 2. The grooves are 8mm apart, so you get around 50 mm of height adjustment 3. No 4. No The concept is you choose what height you want and set the circlips at that height then put them in the car. The standard circlip groove is 355 mm centre of wheel to guard, which is 25 mm lower than the new car standard with the Whiteline coils. So you can go down to 347mm, 339mm and 331mm. Or up to 363mm or 371mm. These are the most common heights found in R33GTSTs. Any lower than 331mm and you have severe geometry problems, excessive camber, radical drive shaft angles (looses HP) and there is simply not enough travel to soak up the bumps. The 371mm is close to standard for people who need the height for clearance but they want good handling at the same time. cheers

The problem is there are a number of cars that use the same basic injector design, 1JZ 2JZ VG30 SR20 RB25 etc. Nismo obviously use the Nissan style, but the other manufacturers seem to prefer the Toyota style. Probably for volume reasons and the shear size of the US market for Toyota injectors. That's why for the last 2 X RB25's we have done, I used S15 JDM manual injectors. At 444 cc's they handle as much as I would want out of a standard internals RB25. Once you start paying for engine rebuilds with forged components a couple of hundy$ for collars gets lost in the rounding. cheers

The attachment at the bottom has all the options settings and prices. That's the best I can do until the gallery is working again. cheers

R32 GTS4's can be tricky. At the bottom of the rear shocks on yours does it have the fork (like a GTR) or a bush (like a GTST)? I have already done the valving for the R32GTR front shocks which will work very well in the GTS4, plus the spring rates and stabiliser bar rates. I haven't finished the rears yet though, but it is only a few days away. Did you want adjustable or fixed stabiliser bars? cheers

Oh., 36-38 psi is standard. cheers

Interesting, the F20 turns clockwise and the H22 turns anti clockwise, so that 250kph was in reverse, right? cheers

Whiteline kits for some cars don't have revalved shocks as the standard valving is OK for the spring rates. Others car, they have to be revalved as the standard valving is not OK for the springs rates, they are designed for only standard spring rates. I have specified the valving for these as I believe that they needed changing for the springs rates. Plus I have built in enough window in the valving so that the stabiliser bar rates I have chosen are also covered. I have also specified the extra circlip grooves for the most popular ride heights. Standard Bislteins only come with one circlip groove, sometimes 2 if the same shock is used on 2 different cars. It costs around $10 per groove extra to have them put in, for a set of 4 shocks with 4 extra grooves per shocks is around $150. cheers

For some time I have been getting requests from many people for my recommended suspension components and settings. So I have organised a SAU Group Buy for Whiteline suspension components and Bilstein shock absorbers for R33GTST Series 1 and Series 2. We get 15% discount off recommended retail and free freight if the individual order is over $500. Plus anyone who spends $1,000 gets an additional 5% discount. I have chosen the springs rates and the stabiliser bar rates based on my experience with this model. Plus the shocks come with matching valving for those spring rates and 5 circlip grooves for setting the height up just how you want it. In addition the adjustable stabiliser bars come with 2 extra holes for even more adjustment. The recommended settings for road use are also included. Delivery is via Toll Priority and I have organised an Australia wide price, so it doesn't matter where you live, you will get the parts at the same price as everyone else. Please pop over to the Group Buy section for full details. cheers PS; I did R33GTST as it is the most popular Skyline model, but if there is enough interest for other models I can organise a similar Group Buy. So please let me know the level of interest. Obviously it will take me a little while to specify all of the spring and stabiliser bar rates and the shock valving to suite.

As you may have noticed I have organised a SAU Group Buy for Whiteline suspension components and Bilstein shock absorbers for R33GTST Series 1 and Series 2. I chose this model as it is the single most popular Skyline. If I get enough support I can also organise similar for R32GTST, so please let me know the level of interest. cheers

I don't know why you are bothering; $US429 + $US13 for freight = $US442 = $A590 + 10% GST = $A650. You can buy brand new Sard 63508's for $A686 from Nengun. cheers

Most bearing shops have C Spanners on the shelf, try your local CBC Bearings. cheers

Sorry, I don't understand the question. Have a look in the Stagea Suspension thread and then ask the question again. Cheers

I don't have my gear charts for Skylines with me either, again from memory 275kph = ~8,500 rpm. If it has enough power to push it there of course. At Philip Island we get to around 265 kph on the main straight which is somewhat downhill, and that's with 380 4wkw cheers

I am not a fan of Konis in Skylines, the Bilsteins are a better compromise in the handling versus ride comfort stakes. cheers

No problems Brendan, ours should be well and truly finished by then. You can then have confidence either way. cheers

How do you know that the oil pump is not working? Check that the oil pressure gauge is not the problem. cheers

Hi Brendan, S1 Stagea has 370 cc side feed high impedance (13 ohms) injectors, same as R33GTST, so very common. In a 6 cylinder engine 370 cc's = 370 bhp = 276 kw - 70 kw for losses = 206 4wkw. That's at standard fuel pressure (36-38 psi). We just finished tuning an R33GTST that made 225 rwkw on standard injectors with a small increase in fuel pressure (45 psi). We are far from the only ones, Reflex (tuned by Chasers) made 231 rwkw wiht standard injectors and an increase in fuel pressure via a Nismo FPR (~$150 from Nengun). The next step up in injectors is the S15 JDM manual, they are 444 cc's. In a 6 cylinder engine 444 cc's = 444 bhp = 331 kw - 70 kw for losses = 261 4wkw. After that you are looking at something like Sard 550 cc's (part #63508). In a 6 cylinder engine 550 cc's = 550 bhp = 410 kw - 70 kw for losses = 340 4wkw. They are available from Nengun for around $700 delivered (watch out for duty and GST though). cheers

You can get Yokohama A048R's in 18's cheers

Lets kill this one off right now, I don't have my Honda gear ratio chart with me, but from memory the manual B16A does 27 kph per 1,000 rpm. So 280 kph would be 10,370 rpm. So it's IMPOSSIBLE But wait there is more If I remember rightly the auto is 8% shorter geared, so that would mean 11,200 rpm at 280 kph :lol: cheers

Excellent result, and it really is 231.1 rwkw at 13 psi. The 231 rwkw out of the standard injectors is right up there, what sort of fuel pressure is it running to get that much out of the injectors? I am targetting 200 4wkw out of the Stagea (equiv to 215-220 rwkw) and I am curious as to the fuel pressure I might need to run. cheers

Hi Mark, lots of things cause knock, so there are lots of cures. 1. Low octane fuel, use higher octane 2. Too much ignition advance, retard the ignition 3. Too lean A/F ratios, richen them up 4. Too high inlet air temps, lower boost, better intercooler 5. Too much boost, turn down the boost 6. Too high a compression ratio, lower the compression ratio I am surprised that they went straight to #5 and then suggested #6 as the solution. Personally I would have started with, #1 what fuel are you using? Should be BP Ultimate 98 in Brisbane, as BP has a refinery at Bulwer Island. Then I would have retarded the ignition timing #2 in the areas where knock was too high, and left it alone or advanced it in areas where it could handle more advance. As that is better for response. At the same time I would have looked at the A/F ratios #3 and made sure that they weren't too lean in the areas where knock was too high. Maybe then richened them up slightly. Then I would have had a look at the inlet air temps, and if they were too high had a look to see what was causing that. Every engine is different, but I would be surprised if you couldn't get 300 rwkw with a T60-1, the relevant compressor map follows; As you can see 50 lbs of airflow per minute (easily enough for 300 rwkw) is availalbe at 1.2 bar (18 psi). Boost at 1.6 bar (23 psi) is way outside the efficiency islands, and is the primary cause of too high inlet air temps, ie; #4. I noted on your list of mods that camshafts are not included. Personally I wouldn't be spending my money on a thick head gasket and introducing other problems, I would put in a set of Tomei 256 degree Poncams instead. That will lower the dynamic compression ratio and provide more airflow capacity at lower boost. It's a win win scenario. Hope that was of some help cheers PS; I wouldn't be going much over 300 rwkw with standard internals.
