:D 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 :no:

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?

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

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

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.

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? :P:laugh: :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 :geek: 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!!

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

ooooooorrrrrrrrrrrr, its pretty.

Why aren’t the ports covered??? :laugh:

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

lookin good, good to see some further progress :D 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.

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.

    • From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
    • Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.      
    • Onto the android unit. You need to remove the top screen because there is a daughterboard to put inside the case. Each side vent pops out from clips; start at the bottom and carefully remove upwards (use a trim remover tool to avoid breaking anything). Then the lower screen and controls come out, 4 screws, a couple of clips (including 3 flimsy ones at the top) and 3 plugs on the rear. Then the upper screen, 4 screws and a bunch of plugs and she is out. From there, remove the mounting brackets (2 screws each), 4 screws on the rear, 2 screws top and bottom and 3 screws holding in the small plates on each side. When you remove the back cover (tight fit), watch out for the power cable for the fan, I removed it so I could put the back aside. The mainboard is held in by 1 screw in the middle, 1 aerial at the top and 3 ribbon cables. If you've ever done any laptop stuff the ribbon cables are OK to work with, just pop up the retainer and they slide out. If you are not familiar just grab a 12 year old from an iphone factory, they will know how it works The case should now look like this:
    • Switching the console was tricky. First there were 6 screws to remove, and also the little adapter loom and its screws had to come out. Also don't forget to remove the 2 screws holding the central locking receiver. Then there are 4 clips on either side....these were very tight in this case and needed careful persuading with a long flat screw driver....some force required but not enough to break them...this was probably the fiddliest part of the whole job. In my case I needed both the wiring loom and the central locking receiver module to swap across to the new one. That was it for the console, so "assembly is the reverse of disassembly"
    • But first....while I was there, I also swapped across the centre console box for the other style where the AV inputs don't intrude into the (very limited !) space.  Part# was 96926-4GA0A, 284H3-4GA0B, 284H3-4GA0A. (I've already swapped the top 12v socket for a USB bulkhead in this pic, it fit the hole without modification:) Comparison of the 2: Basically to do the console you need to remove the DS and PS side console trim (they slide up and back, held in by clips only) Then remove the back half of the console top trim with the cupholders, pops up, all clips again but be careful at the front as it is pretty flimsy. Then slide the shifter boot down, remove the spring clip, loose it forever somewhere in the car the pull the shift knob off. Remove the tiny plastic piece on DS near "P" and use something thin and long (most screwdrivers won't fit) to push down the interlock and put the shifter down in D for space. There is one screw at the front, then the shifter surround and ashtray lift up. There are 3 or 4 plugs underneath and it is off. Next is the rear cover of the centre console; you need to open the console lid, pop off the trim covering the lid hinge and undo the 2rd screw from the driver's side (the rest all need to come out later so you can do them all now and remove the lid) Then the rear cover unclips (6 clips), start at the top with a trim tool pulling backwards. Once it is off there are 2 screws facing rearwards to remove (need a short phillips for these) and you are done with the rear of the console. There are 4 plugs at the A/V box to unclip Then there are 2 screws at the front of the console, and 2 clips (pull up and back) and the console will come out.
