As for TopGear, its fun but I'll more then likely only be watching this year too. I'll try and compete in only the JDM rounds at the QRDC events this year. Would be nice to have more contenders this year though. The most JDM cars entered last year in one round (other then MX5's) was about 9 I think, 6 or 7 of which were WRX's and only 1 of those actually lasted to the final race on Sunday. A couple didnt show, another blew a box, another blew an engine etc etc. Would be nice to see some of these fast Skylines and S13/14/15's out there.

I'd still like to get involved in that, but after a run at QR I have a few issues to work through before its anywhere near ready to circuit race. Main ones being overheating after just a couple of laps and turbo flange studs/nuts coming loose. But with the car running like a dog and only on 14psi it ran a 58.23 on the Sprint track on 3yr old Toyo RA1s, so the old Datto shows a bit of promise. I've also made a few suspension changes after its first visit to a proper racetrack - before this it was all hillclimbs which are much lower speed and didn't really show up just how soft the suspension setup was. The car just about falls over in turn 2 at QR!

Yeah but it weighs about the same as a large pizza from Domino's too :)

Do you have an oil cooler of some sort on there? If not, get one but don't get a chinese one unless you dislike your engine. The cooler might be ok but the oil lines are poor quality rubber. Saw one in use on an R33 with big dollar engine where the rubber was falling apart and blocking the turbo oil feed. This caused the bearings to collapse and the turbo to die, followed by the bearing parts travelling to sump, being eaten by the dry sump pump and so on... Chinese hose cost bigtime.

hey harry

have you looked at the type of material for being used for your turbo studs?

i only ask as we were having the same problem once. it turned out to be the material the studs were made of , they were turning to jelly when hot and stretching,

i thought they were using genuine studs and they werent! the turbos nearly fell off!!

Inconel studs are your best bet :P ...not cheap but no chance of stretching at temps

thanks for the tips guys. I've just replaced the studs with Sonic studs (mild steel) and metal-lock nuts. I really only bought them because they had the metal-lock nuts - I have no idea about the quality of the stud material. I always use genuine flange gaskets, but never thought about sourcing studs from Nissan. If it happens again I'll go looking for inconel studs. where did you guys source them?

RA1's are the gun hillclimbing tyre, but you have to buff them down for best performance. They do go off quickly on heavy cars if you're running multiple laps, but they're perfect for hillclimbing. The other options are RE55S WT compound - Mike Collin's 43sec WRX runs on them. Or the new Dunlop - everyone who's tried them at Mt Cotton has beaten their PB, so they look promising.

yeah, it is light. at least until I get in it! should be in the low 900kg range I'd say.

it has a PWR oil cooler, but only had rubber lines fixed with hose clamps so it may have been done on the cheap... I'm relocating it to beside the radiator (was behind it) and using quality braided lines and fittings. also replacing the intercooler with one under the bumper that won't block the radiator anything like as much, and have fitted a front spoiler. Oh, and moved the air filter which was partially behind the radiator! and making some shrouds for it. And I've turned the boost down to 1bar instead of 1.5. Hopefully all that will get the overheating sorted and the lower boost should reduce the heat build up in the manifold a bit. Then it will get some suspension tweaks that will hopefully make it quicker around the track even though it lost 30 or 40kw at the wheels. oh, and I've also got to sort the fuel system - the surge tank is under the car nearly horizontal... the car has alot of good gear, but the execution is lacking in alot of areas. I guess that's the risk you take when you buy a car someone else built. But at least its all minor stuff.

If my memory serves me correctly I got my Inconel studs via Apexi. That was all the way back in 1999 though so I hope my memory isn't failing me. They may well be much more readily available now? For interest, I never had any issues with manifolds/turbos loosening on that vehicle using Apexi bits after lots of circuit use :blush:

We went there in the afternoon last sunday! :miner:

Mark only got three runs with a best time of 44.44 on the mediums we used last year at tsukuba so i am trying to find a softer tyre to have another go!

http://www.skylineshack.com/racecar/000_0151.jpg <--- is a big pic so i won't put it up

I havent ran my car much and only at winton, power wise it was STD boost & missing up high (thanks to coil) but best time out of it was 1:41 at winton... and that was basically it's first run (was a regularity event so it was consistancy not speed). will have to get it back over...

But for a small rural town, we have a fair few dedicated track skylines...

cars below i have a share in

another R33 (RB30DET in the build) ---> http://www.deniliquinsportingcarclub.com/nissan/

Aus 31 with RB30ESCharged (our dirt car)

mates cars

GTS-X <--- Gibson replica (RB25)

32 GTR <--- my boss's car

some of our clubs members previous cars have been

R32 Tk GTR

R32 GTS-4

R32 GTS-T (4door)

Aus R31 with RB25DE (which done mid 40's at winton)

by the way the bar on my 33 racecar is a modified Tommy Kaira bar, with scoped air ducts etc. we made a mould if anyone wants one. (the indicators are air ducts for brakes etc)

I have no recent pics, but this is of my CA18DET powered 1600 wagon (with VG30BB turbo) built for show/circuit/street

1600.jpg

I built this mad 200B also ... with a supercharged SR20DE motor. Surprised a few people at the drags LOL

I'll hit the Mallala race circuit with the Stagea next month before I fit the turbo and cooler kit for a benchmark.

BIKES

When it comes to bikes, I took my TLR to track days

    • OK, so again it has been a bit of a break but it was around researching what had been done since I didn't have access to Neil's records and not everything is obvious without pulling stuff apart. Happily the guy who assembled the engine had kept reasonable records, so we now know the final spec is: Bottom end: Standard block and crank Ross 86.5mm forgies, 9:1 compression Spool forged rods Standard main bolts Oil pump Spool billet gears in standard housing Aeroflow extended and baffled sump Head Freshly rebuilt standard head with new 80lb valve springs Mild porting/port match Head oil feed restrictor VCT disabled Tighe 805C reground cams (255 duration, 8.93 lift)  Adjustable cam gears on inlet/exhaust Standard head bolts, gasket not confirmed but assumed MLS External 555cc Nismo injectors Z32 AFM Bosch 023 Intank fuel pump Garret 2871 (factory housings and manifold) Hypertune FFP plenum with standard throttle   Time to book in a trip to Unigroup
    • I forgot about my shiny new plates!
    • Well, apparently they do fit, however this wont be a problem if not because the car will be stationary while i do the suspension work. I was just going to use the 16's to roll the old girl around if I needed to. I just need to get the E90 back on the road first. Yes! I'm a believer! 🙌 So, I contacted them because the site kinda sucks and I was really confused about what I'd need. They put together a package for me and because I was spraying all the seat surfaces and not doing spot fixes I decided not to send them a headrest to colour match, I just used their colour on file (and it was spot on).  I got some heavy duty cleaner, 1L of colour, a small bottle of dye hardener and a small bottle of the dye top coat. I also got a spray gun as I needed a larger nozzle than the gun I had and it was only $40 extra. From memory the total was ~$450 ish. Its not cheap but the result is awesome. They did add repair bits and pieces to the quote originally and the cost came down significantly when I said I didn't need any repair products. I did it over a weekend. The only issues I had were my own; I forgot to mix the hardener into the dye two coats but I had enough dye for 2 more coats with the hardener. I also just used up all the dye because why not and i rushed the last coat which gave me some runs. Thankfully the runs are under the headrests. The gun pattern wasn't great, very round and would have been better if it was a line. It made it a little tricky to get consistent coverage and I think having done the extra coats probably helped conceal any coverage issues. I contacted them again a few months later so I could get our X5 done (who the f**k thought white leather was a good idea for a family car?!) and they said they had some training to do in Sydney and I could get a reduced rate on the leather fix in the X5 if I let them demo their product on our car. So I agreed. When I took Bec in the E39 to pick it up, I showed them the job I'd done in my car and they were all (students included) really impressed. Note that they said the runs I created could be fixed easily at the time with a brush or an air compressor gun. So, now with the two cars done I can absolutely recommend Colourlock.  I'll take pics of both interiors and create a new thread.
    • Power is fed to the ECU when the ignition switch is switched to IGN, at terminal 58. That same wire also connects to the ECCS relay to provide both the coil power and the contact side. When the ECU sees power at 58 it switches 16 to earth, which pulls the ECCS relay on, which feeds main power into the ECU and also to a bunch of other things. None of this is directly involved in the fuel pump - it just has to happen first. The ECU will pull terminal 18 to earth when it wants the fuel pump to run. This allows the fuel pump relay to pull in, which switches power on into the rest of the fuel pump control equipment. The fuel pump control regulator is controlled from terminal 104 on the ECU and is switched high or low depending on whether the ECU thinks the pump needs to run high or low. (I don't know which way around that is, and it really doesn't matter right now). The fuel pump control reg is really just a resistor that controls how the power through the pump goes to earth. Either straight to earth, or via the resistor. This part doesn't matter much to us today. The power to the fuel pump relay comes from one of the switched wires from the IGN switch and fusebox that is not shown off to the left of this page. That power runs the fuel pump relay coil and a number of other engine peripherals. Those peripherals don't really matter. All that matters is that there should be power available at the relay when the key is in the right position. At least - I think it's switched. If it's not switched, then power will be there all the time. Either way, if you don't have power there when you need it (ie, key on) then it won't work. The input-output switching side of the relay gains its power from a line similar (but not the same as) the one that feeds the ECU. SO I presume that is switched. Again, if there is not power there when you need it, then you have to look upstream. And... the upshot of all that? There is no "ground" at the fuel pump relay. Where you say: and say that pin 1 Black/Pink is ground, that is not true. The ECU trigger is AF73, is black/pink, and is the "ground". When the ECU says it is. The Blue/White wire is the "constant" 12V to power the relay's coil. And when I say "constant", I mean it may well only be on when the key is on. As I said above. So, when the ECU says not to be running the pump (which is any time after about 3s of switching on, with no crank signal or engine speed yet), then you should see 12V at both 1 and 2. Because the 12V will be all the way up to the ECU terminal 18, waiting to be switched to ground. When the ECU switches the fuel pump on, then AF73 should go to ~0V, having been switched to ground and the voltage drop now occurring over the relay coil. 3 & 5 are easy. 5 is the other "constant" 12V, that may or may not be constant but will very much want to be there when the key is on. Same as above. 3 goes to the pump. There should never be 12V visible at 3 unless the relay is pulled in. As to where the immobiliser might have been spliced into all this.... It will either have to be on wire AF70 or AF71, whichever is most accessible near the alarm. Given that all those wires run from the engine bay fusebox or the ECU, via the driver's area to the rear of the car, it could really be either. AF70 will be the same colour from the appropriate fuse all the way to the pump. If it has been cut and is dangling, you should be able to see that  in that area somewhere. Same with AF71.   You really should be able to force the pump to run. Just jump 12V onto AF72 and it should go. That will prove that the pump itself is willing to go along with you when you sort out the upstream. You really should be able to force the fuel pump relay on. Just short AF73 to earth when the key is on. If the pump runs, then the relay is fine, and all the power up to both inputs on the relay is fine. If it doesn't run (and given that you checked the relay itself actually works) then one or both of AF70 and AF71 are not bringing power to the game.
    • @PranK can you elaborate further on the Colorlock Dye? The website has a lot of options. I'm sure you've done all the research. I have old genuine leather seats that I have bought various refurbing creams and such, but never a dye. Any info on how long it lasts? Does it wash out? Is it a hassle? What product do I actually need? Am I just buying this kit and following the steps the page advises or something else? https://www.colourlockaustralia.com.au/colourlock-leather-repair-kit-dye.html
