stop being such a girl Russ

btw need Duncan to go and buy more car stuff- my shoe fund is getting seriously depleted this month

Don't worry Kel, I'm sure I can help Duncan build up your shoe fund! I've got a pile of catalogues a mile high to sort that one out.

yeah the rear end mods would not be cheap, 10+ hours of work by a fabricator who knows what to do. John from UniqueAutosports was very helpful with both information and price for this car.

The new arms were also very cheap from Just Jap. Even at retail prices upper control arm(249), traction rod (199), lower control arm (495) and hicas replacement arm (219) are under 1200.

So now we basically have all new rear end - all arms replaced, all new spherical rod ends where bushes used to be and we put in new wheel bearings as well. And also a custom sway bar from Gary at Selbys. If the back of this car is not stable and predictable no gtr ever will be.

We do still need to shim up the diff, about $300. Not going with an aftermarket one for $2k when nissan gave us a perfectly good mechanical one.

Does the R32 GTR have the same diff centre as the R33 GTS-T? The R33 ones are viscous aren’t they?

[Duncan]

yeah gtst is viscous LSD, but 32 and 33 gtr is 2 way mechanical from fcatory. so they just need shimming up and then they are a nice tight 2 way diff. 1 or maybe 1.5 way diff would be better but for for 1.5k more....

btw the viscous lsds are shithouse (you probably noticed already). anything oevr 70000klm with a bit of hard driving they are probably single spinning. my gtst was signle from about 100,000klm and the z is the same already (about 60000klm). easy to put a mechanical centre in hte gtst housing though

btw neil, and mark, you bith suck abt answering your hpones. see you both tmorrow

[BOZ22N]

Thanks Drunkin. I just shimmed up my viscous one and it does the trick so far. May be have to up grade to one of these fancy non hicas GTR rear ends in the GTST one day.

Hey Guys,

I have a decision to make, keep the twin's. or go to a single t88.

what would a t88 go like on the track? i figure your always going to be above 5000rpm so boost lag wont be that much of a pain. the power delivery would be scary for the track

[haw001]

Definitively keep the twins. On the track torque is as, if not more, important that pure kws. The big single sounds great, and yes you will spend most of the time above 5000 rpm, but you just won't be able to keep it there all the time. You can get bogged down in traffic, miss a gear, or simply shift up too soon and find that your too far in to shift down and yet still stuck before the boost kicks in.

Even when it comes to the twins, you need to decide which way you want to go. Top end or bottom torque. Duncan and I have (or had) very similar cars except for the turbos and there was a subtle difference. His bigger N1 turbos should have made more power, but tended to take longer to spool up. i prefer smaller faster spooling turbos to pull you off the line and out of the corner, and still I can tell you that there have been tons of times when I have been in the wrong gear waiting for them to spool up. It's a painful wait.

The other big advantage is a more linear, predictable, power curve. With the big single, you get nothing, nothing, nothing, then wham, whiplash. It just doesn't lend itself to dealing with traffic on the track or the short windy tracks like Wakefield. Ask around with all the other people who actually have caged and raced a car with others in a race scenario, not just those who have GTRs they take for track days. I raced against plenty of big muscle cars with big hp way over what I run, and they can't come anywhere near a well set up rb26 when there is any sort of cornering.

[Risking]

For what you want andrew I agree with mark.

Keep the twins but perhaps upgrade them if your chasing more.

Im using twin HKS GTRS' and its now awesome to drive. They deliver a nice usable power band that has plenty of grunt to pull you from turns (providing the gearing is correct) and also monster top end for the straights and high speed corners.

Im not a fan of low end punchy turbos on "light weight" GTR's. They just seem to be lacking something.

I drove 3 cars at oran park a few weeks ago.

One with the GTRS, jess' with stock turbos and Jays with GTss. The latter two are quick out of the corners but lacked the raw grunt of my GTR.

Each to their own when it comes to turbo selection and driving style I guess. Perhaps try and take a few for a run if possible before deciding?

On another note picked up the new Tilton pedal box this weekend. Very nice bit of gear.

Just need to get the car back from being out on loan now.

Are you running the GT-RS on standard capacity?

I had a good day with my car today... It's finally coming back together... Finally finished up all the wiring for electrics (gauges, boost controller, attesa controller, etc... which meant that I could start putting her back together. Soldering with your body contorted around a roll cage isn't the most pleasant thing in the world

Is it just me, or does everyone stuff up cutting their first dash to fit around a roll cage? :laugh:

Bit concerned that the speedo, windscreen wipers, and indicator stalk aren't working (hazards are though)... Probably broken speedo cable, which'll be a pain the ass to change just after I put everything back into the car No idea about the indicator stalk or wipers though...

Now I just need to:

Buy a speedo cable, front windscreen rubbers, ATESSA gyro unit.

Install the above, and the oil cooler, oil pressure/oil temp/water temp sensors,

Remove the stupid 5% jap limo tint from the windows

Get the engine tuned to make the thing drive properly again.

And then it should at least be drivable again

Then to tackle the two most expensive bits on the car.... Brakes and suspension.

<sigh>

I guess it does sound right, kinda what i expected with a reply.

i might hang onto the turbo anyway and just see how it goes, it does look like alot of fun (watched a few youtube videos on track gtr's with t88) but i did enjoy the response of the twins and the power curve isnt at crazy as the t88. i do like eastern creek out of most tracks.

Andrew, we need to work out when to meet for this shaft. as you can add that to your list too!!

[Duncan]

stuff twins go for tripples. requires some manifold mods but the low down response is amazing.

andrew, good to hear you are making good progress at last.

here are today's (poor) pics....

as with earlier motors we didn't have the nissan rubber washers (and weren't going to buy them at about $5 each for 20 of them). so we cut down a rubber hose of the right diameter into 5mm lengths and used that instead.

we have taken john's advice and added an accusump (well a moroso oil accumulator but thats the same thing). we are going to try and shove it where hicas normally lives, but its amazing how big a 3 litre container is.

and we have reinforced the fuel cell mounting, added an angled filler, and created the world's first skyine. sorry nissan

[BOZ22N]

ooooooorrrrrrrrrrrr, its pretty.

Why aren’t the ports covered???

[Merli]

Where the hicas usually lives? As in the rear of the car? Wouldn't you want the accusump closer to the engine?

How am I supposed to sneak in and sprinkle metal shavings into the engine if they cover them up???

[unique1]

lookin good, good to see some further progress did u get the accusump recently or had it from previous setups? how much is the entire setup worth and did u get it through unique autosports?? i was gonna order direct from the US but the dollar has gone to shit so not sure what to do now.

[haw001]

Accusump was about $250 second hand, plus whatever fittings and hoses will be needed, say another $30 should cover it.

It will be located where the Hicas pump/solenoid thingy used to live, that is under the plenum on the chassis rail. About as short a line to the oil feed as possible without screwing it straight into the block (which could be a bit difficult).

I'll mount the manifolds and turbos tomorrow, which will cover one side at least. Still waiting on the plenum for the other side.

If you've got all the rest of the gear to go with it already like the manifold, exhaust, not to mention the computer that will work with a MAF then you may as well give it a try, but if you don't, then these things will add a lot to the cost and not be reusable if you switch back to twins.

Actually its a good idea to give John at UAS a call, he had a second hand one there last time I went too. And it had the electric switch attached so you can show a light if its activated.

Yeah its the whole kit, from exhaust to manifold.

i run fcon pro v, so that should work. i can get a map done for the t88

or do i need to use twin Maf's for the t88??

my friend says he can make the t88 nice and responsive, tho obviously not like the twins i have.
