The cranck my be standard but im sure it will be all about the clearences, stud size, clamping torques, oil gallery enlargments including bearing shells, i wonder how much nascar engine spec is applied to a meir nissan 6 ?
-
Mate ; how much for the head only no manifolds required and is it still in running order ? cheers george

Gary understand where your coming from but yes in every change that i make i will use my alignment equipment to check and i will be using my corner scales and yes will be keeping records. As most parts that i fabricate and machine including rose joints need to be tested. Chow.There is no doubt that taking out unnecessary movement is a good thing, if done properly. The problems that I see are not in the theory itself but in the physical application of the theory. For example, solid mounting the rear cradle without allowing for adjustment of its angle. Even worse, adjusting control arms with spherical links and not correcting the bump steer. Or using roll centre adjusters without knowing where the actual role centre or the CoG are.Any the sphincter of the universe can buy a box of bits and bolt them on, but it just makes the handling worse if the knowledge on how to use those bits isn't there. If you don't have the knowledge, experience and the equipment to measure the results its pretty much guaranteed to be a waste of time and money. The underlying problem is the parts themselves are relatively cheap (in time and $'s), but acquiring the knowledge is expensive in that it takes time. Then you require the equipment, scales for calculating the CoG, bump steer guage, wheel alignment equipment etc and the knowledge to use them. Lastly I need the time and $'s to test their effects and optimise the set up accordingly. In a full day of testing, with 1 driver, 4 crew and a suspension engineer/manager I might just optimise the geometry. Provided I have spent a full day before hand doing the homework.
In simple terms, what I have found is if I spend $500 on suspension components I often need to spend 20 times that on optimising them. If I don't do that then it's pretty much guaranteed that I will have wasted the $500. It's the reverse of having a big power engine, you spend $10K on buying the engine and $500 turning it.

I'm about to put the skyline on scales this weekend without an engine and gearbox what do you guys think it will weight my normal wet weight is approx 1420 kg nearest guess wins a prize ?? lol.

With two wheel drive and Nissan multilink rear suspension, what are the suspension's critical areas in regard to rear grip and stability?
My wild guess is reducing anti squat, lighter rear springs than front and ensuring toe in at all times.
And is removing the rear ARB completely ever an option?
Richard Sounds like you know a trick or two with suspension setups are you running rosejoints ? and what were the benefits as i'm just in the suck and see stage.
-
The diff bushes have no effect on the suspension geometry, so I can't see how they would affect the handling. Much like engine and gearbox mounts, diff mounts can have dynamic effects (moving mass, inertia etc) if the bushes were badly worn/torn. But I can't say that I have ever seen an R32/33/34 with flogged out diff bushes, they seem very durable and arguably over engineered even for drag cars with 1000 bhp. My personal opinion is that there are better, more effective ways to spend my time and money.
Cheers Gary i;m rebuilding my back end using solid alloy cradle bushes and rose joints in all my arms ect i;m just trying to get a faster reaction out of my suspension.

Yeah I noticed the lack of pumped guards after I saw the pictures, either way the build looks pretty good.
thanks i tried fitting some gtr fibre guards but need some advice with fine tuning the height
-
Wouldnt happen amongst us QLD'ers.
Bunch of poofs you southern'ers.
go the queenslanders !!! anyway do you have a contact number for airforce mike now based at newcastle ???
-
Looking good, keen to see progress pictures. Seems like there a few white R33 GTR track cars in the build at the moment
Mate just for the record my car is only a gtst rear wheel drive and after this rebuild i;m hoping for a trouble free season.

Hi Chris; the current turbo setup is garrett gt35 it runs around 500 rw hp i have tried to4z on a previous engine great for horsepower but to laggy. at the moment i;m using tow straps on a sandwich plate seem to work i;ve been pulled out of the gravel trap at queensland raceway and it survived .Dont know if I've missed it anywhere - but what is the turbo of choice for this car mate?Also - tow points - what are you going to use? straps or hooks? I can see the hole on the front bar - if its a hook, whats the best way and place etc to mount the hook to and with?
(n00b question alert
)Cheers!
Chris

how much does it weigh?
the wet weight is approx 1400 kg:s i;m slowly reducing it my biggest gain was wiring harness about 20 kg.

This car is a beast when it holds together. If memory serves me it has runn 55's on the sprint circuit at QR. Get ya finger out George, You missed a great day yesterday.
Noel stop waving the carrot my shed leave pass has been reduced to just n3 hours a night but on a light note i;ve just finished changing my inner door skin and picked up 2kg;s and 1 kg on steering column mod.
-
I like!!!!!!
I'll keep an eye on this thread so I can get more ideas for my 33
Do you guys have any ideas on removing weight out of on my r33??? i started today with removing the steering column support bracket i think i might pick up 0.3 kg i guess i still have a long way to go .
-
yeah trims will be fine thats why we left the lip to rivet into. windows will be a bit trickier we may end up with the first unframeless windowed r32
also removed a the remaining boot floor between the chasis rails to fit the fuel system in better. It looks like getting a filler to the fuel cell will be tricky. attessa resoviour is moving too.
hey guys you can leave doors without inner skin you just need to tension diagonally with light weight 4mm stainless wire in a letter x will keep door from flexing and weight saving.

Here are some photos of my r33 circuit car that i'm currently rebuilding.
Hi Roy i have the usuall stuff a RB 30 bottom end that gives me more problems than a 16 yearold school girl and ppg box mechanical diff alcon brakes i built it myself about 4 years ago and now i:m doing a full rebuild .

Has anyone benefited by using traction control on a rear wheel drive r33 skyline on track conditions and what gains.
-
Hey mate, what state are you in? And what sort of cost do you think it will be?
phunky monkey i;m in brisbane and ican pass on contact number he will be doing my car next week if you can give me your car details it will speed the process.
George.

This is the kit I got: http://www.painlessperformance.com/webcata...archField=50003
and this is the page you'd want, it's under drag racing: http://www.painlessperformance.com/webcata...assis+Harnesses
Mate you can get a race car harness in australia i;ve just stripped every wire in my R33 track car, next week there;s a electrician who only fit;s out track cars coming over to run a basic loom will only have starter button , fan, brake lights and the wiring around engine which is quick release at the firewall .
-
thanks Gary and others for the thread, great informative info and helps in my decision making abit
while were on the subject of traction has anyone fitted solid plastic or alloy diff support bushes on the rear diff on r33 gtst and found any improvement in rear feel on track conditions as i haven;t been able to find urethane bushes i;m resorting to nylon.
-
From 9 years experience with both of them in a race environment, I can tell you with certainty that a GTR is damn site harder to set up than a GTST. I don't see a real lot of difference in the driving talent required either, I'm crap in either of them.
Cheers
Gary
Gary: i guess i'm just pushing my 2 wheel GTST barrow, i have never driven a GTR nor had any mechanical experience with one . Mate I;m to old to be retrained in 4 wheel technology at present my GTST is enough of a challenge. Maybe one day someone will offer me a drive and i;ll have a change of heart, buy for now when on the track i;ll have to treat all GTRS as the enemy.
Ta George.

i know this may be a silly question but Gary if u had to choose between a gtst and gtr for circuit and had an unlimited budget would u still go for a gtst? i dont have an unlimited budget but am still undecided on which way i wanna go.
say your pushing 450kw at wheels with a rb26 and t04z (good power between 4200rpm-9000rpm) and have a gtr ppg dogbox already would u ever considering using a gtst? do u think i would get any advantage with a gtr over gtst with that combo? I dont know if you know Barbegallo Raceway in perth but this is the track i would be running on 99% of the time and possibly the track down at Collie but only on rare occasions.
I can either...
use the ppg box with cut off tf case for rwd and my engine as is making 450kw in gtst?
use the ppg box with cut off tf case for rwd and my engine with a gt3540 making around 360kw in gtst?
or ppg box and 450kw engine combo in a gtr?
im soo unsure and keep trying to convince myself on either options its driving me crazy lol
Mate go the GTST you dont need talent to pull good times in a GTR but i guess it depends on what class your intrested in running in.

Gary you just shatteredmy dreams of achieving a 1 second gap with a GTR on time attack in brisbane . So This is the challenge ! suspension tuning with your input and your componantry mate i;m only looking for 1.02 misrebale seconds is it possible ???Nope, actually the reverse due to the following.Nope, a GTR is much more front weight biased (~180kgs) plus RHS weight biased due to the 4wd hardware. Add the driver to the RHS and they are quite difficult to balance, front to rear and left to right.
The single advantage of a GTR is traction from the 4wd. That can manifest itself in a faster single lap time if the 4wd is needed for the power level. Or, a faster full race distance due to better use of the tyres, particularly rears.
Cheers
Gary

Are there any advantages in suspension tuning in a Gtr over Gts for track work if using same brand componantry ?
and can you achieve the same balance when stressing and wedging the chassis ????

Hey mikey have i told you that there is no nissan engine which has survived longer than 6 seconds with that kind of boost levels.
