yeh thats our car...my old man discovered sau and is slowly learning about online forums lol....so he has been doing his own thing on here. Hopefully in a few weeks we will have a new motor that will hold together! But in the long ass wait for the machining to happen we have been working on a few other things to hopefully make the car abit quicker/reliable/tidier and more fun to drive.

Very nice setup Darren ;)

The beast should be fun on the track.

We should put a SAU GTR team into the Queensland 500 Team Enduro at QR. It should be fun :laugh:

Hey mate will definatly be keen on putting together a taem for the QLD 500 I would say Mark and Russ would be more than interested aswell. Would be a great event and I think a team of GTR's would do really well in that event. I will be catching up with Russ this weekend sometime so will gee him up and will have a chat to you about at the next track day.

How have you found the scavenger from the rear of the head??

Im using -12 scavnegers and a -10 from the rear of the head.

I was concerned about the feed not getting enough oil at lower speeds and damaging the pump so ive left the oil restrictor out for the time being.

Curious to know your thoughts??

Not had any problems with the scavage of the head as the pump does not need a great deal of oil in the scavage stages to keep it properly lubricated. Have run the same dry sump set up on another car that i have built that has done quite a few klm's now and works a treat. With a dry sump set up you should not need to run a oil restrictor in the block so you should not have any problems.

The wiring is for the motec is around 3/4 done at the moment should be done by the end of the week or early next week and then will be getting a tune so should have some results by then providing no little hicups pop up.

Hey guys a quick update. Had a few little issues with the car wich i should now be on top of. Unfortunatley though i have been unable to dedicate much time to the car over the last few months due to work commitments the ecu install is done and have performed some cold start and light throttle tuning. I will hopefully get the time to get the full power tune done early in january as my tuner is back on th 12th so i will be trying to get the car booked in first cab of the rank.so will hopefully have a some results to post up before to long.

Angus the fuel pumps are working without any problems though this has only been during light load running in.

Bosch pumps are always a little noisy but this seems fairly unavoidable.

Though I have run the same fuel system in another GTR that i have built that has done some serious track time without any problems. The fuel temp does not seem to be a problem but if you do have any heat issues with your fuel i would recomend checking your fuel reg as I have had some drama with fuel temps while running sard regs as they seem to restrictive for high hp aplications once changed to a larger free flowing reg the fuel temp issues were no longer a problem. Hope that helps Daz.

Hey all just a quick update. Have had a few headaches with the car got it on the dyno and did all the light throttle and cold start and then started to give it a few power runs.

This is when the drama started to unfold with 1bar of boost as soon as it would get to 5k rpm it would start to push coolant out of the radiator but the car never ran hot. So off the dyno it came to get to the bottom of the problem. It had built up so much pressure in the cooling system that it had started to baloon the end tank of the radiator. so pulled the engine out and stripped it down. Had the head crack tested all ok deck of block dead straight. I could see slight indication that the head gasket had lifted. After a bit of head scratching finally found the problem was a faulty thermostat it was opening enough to circulate thru the cooling system at lower rpm but causing a major restriction as soon as rpm was lifted. This would have contributed to creating a weak spot in the gasket allowing combustion pressure to finnish the job. a bit odd thou as I would have thought that the pump would have cavitated or radiator hoses would have let go first ( they were balloning and makeing an attempt to let go but somehow managed to hold on). Car is now back together and all seems fine have had it on the dyno breifly and have driven it for a few klm's to check coolong system is operating as it should be. and all seems good.

Now just waiting on my tuner to get back from dubai / shrilanka to finnish off the tune so finger crossed i will have some results within a few weeks. Have also purchased some new suspension components for the car so will post up some pics soon.

Bloody heck that's some rotten luck Darren! Difficult problem to isolate too.

Regarding the hoses not popping first, funnily I've also experienced a similar thing many years ago as a young fool. I was doing many many donuts on the mudflats in a KF turbo 4WD Laser until it was really cooking, and instead of popping a hose or gasket the radiator tanks burst right off it.... big bang!

Glad you found the issue and you can move on mate :P

Car looks great mate!

A lot further along than mine, but I'll catch up eventually :)

Great work, and I can't wait to see more updates! Shouldn't be long before we see this beast terrorising unsuspecting Porsches on the track :(

Thanks guys is coming along but as we all know these things always take longer than expected especially when you run into drama's along the way

That is the plan. I have all the confidence in the world that the car will be more than capable will just have to see about the driver though in saying that there seems to be a lot of accountants and companu ceo's driving porkers that would definatly fit into the same catagory.

      Leak from Tokico BM50 Brake Master Cylinder

      By brillo · Posted

      Hi, SteveL Thank you very much for your reply, you seem to be the only person on the net who has come up with a definitive answer for which I am grateful. The "Leak" was more by way of wet bubbles when the pedal was depressed hard by a buddy while trying to gey a decent pedal when bleeding the system having fitted the rebuilt BM50 back in the car, which now makes perfect sense. A bit of a shame having just rebuilt my BM50, I did not touch the proportioning valve side of things, the BM50 was leaking from the primary piston seal and fluid was running down the the Brake booster hence the need to rebuild, I had never noticed any fluid leaking from that hole previously it only started when I refitted it to the car. The brake lines in the photo are "Kunifer" which is a Copper/Nickel alloy brake pipe, but are only the ones I use to bench bleed Master cylinders, they are perfectly legal to use on vehicles here in the UK, however the lines on the car are PVF coated steel. Thanks again for clearing this up for me, a purchase of a new BMC appears to be on the cards, I have been looking at various options in case my BM50 was not repairable and have looked at the HFM BM57 which I understand is manufactured in Australia.

      R33 GTST Steering Rack (49001-19U05) Rebuild?

      By Gantai · Posted

      Well the install is officially done. Filled with fluid and bled it today, but didn't get a chance to take it on a test drive. I'll throw some final pics of the lines and whatnot but you can definitely install a DMAX rack in an R33 with pretty minor mods. I think the only other thing I had to do that isn't documented here is grind a bit of the larger banjo fitting to get it to clear since the banjos are grouped much tighter on the DMAX rack. Also the dust boots from a R33 do not fit either fyi, so if you end up doing this install for whatever reason you'll need to grab those too. One caveat with buying the S15 dust boots however is that the clamps are too small to fit on the R33 inner tie rod since they're much thicker so keep the old clamps around. The boots also twist a bit when adjusting toe but it's not a big deal. No issues or leaks so far, steering feels good and it looks like there's a bit more lock now than I had before. Getting an alignment on Saturday so I'll see how it feels then but seems like it'll be good to go

      Leak from Tokico BM50 Brake Master Cylinder

      By SteveL · Posted

      I don't get in here much anymore but I can help you with this.   The hole is a vent (air relief) for the brake proportioning valve, which is built into the master cylinder.    The bad news is that if brake fluid is leaking from that hole then it's getting past the proportioning valve seals.   The really bad news is that no spare parts are available for the proportioning valve either from Nissan or after market.     It's a bit of a PITA getting the proportioning valve out of the master cylinder body anyway but, fortunately, leaks from that area are rare in my experience. BTW, if those are copper (as such) brake lines you should get rid of them.    Bundy (steel) tube is a far better choice (and legal  in Australia - if that's where you are).
