I will be taking the car out for its first track day (shakedown) this wednesday at mountain runners Time attack day will be out there for the afternoon session and will also have one of the other cars that I have built 26R32 out there. Should be a good day. This track day is fully booked with some pretty serious cars heading out. I am really looking forward to getting out there and for a few laps after all the work to get the car to this stage. So anyone that can make there way out there for a look I would say it should be well worth the effort. And anyone that has been following my build thread come and say hi.

sweet! best of luck for a trouble free first day mate. :down:

yeah my opinion of the HKS vs generic turbos is about the same as you. as we both know the money especially in the GTR turbos is that the HKS ones put that money into the turbine housings which has a big bearing on how the turbos will behave on the car. I currently have the HKS GT-SS for my car and was thinking that with some decent boost (25psi or so) and with the level of headwork etc that it should make the 350awkw or so that I want, but like you it's not so much the number, mainly I want it to be responsive but not sacrifice any top end (or too much). for my mind on the 2.8 RBs the 2530s are without question the perfect choice. for a 26 that isn't revving to the moon (no dry sump) then it's a bit more tricky to chose between HKS 2530s or GT-SS. hmmmm. I might go the 2530s, I went the GT-SS on the last motor (granted it was not as advanced as this one and had stock diffs. now have GTS4 diffs) and a change might be good.

anyway, enough babble. I hope it's a good day tomorrow. :)

Just a quick update on the cars 1st track shakedown. The car was going well without any drama's in the first session pullling hard needs some work on the wheel alaignment and will need a brake upgrade as soon as the bank account allows. Off the trailer I managed to lap around the 1.00min for the first few laps than managed a couple of .59 sec laps with my fastest being a 58.9 sec lap wich I was happy with but in the 2nd session coming out of turn 1 I had a low oil pressure warning and shut the engine down as sooon as possible and towed back to the pits to find it had thrown all the belts off.

Turns out it has broken the balancer thrue the middle thrown the belts and has damaged the front of the crank and due to the drop in oil pressure need a new set of bearings.

fck mate! that sucks. what a shame. at least the pace was encouraging I guess, but still a bit of a downer to have to be pulling the thing apart so soon. lucky you got off it and hopefully didn't damage that lovely crank... :) you have had some bad luck with the head gasket/thermo problem before and now this. :) cars really can give you the shits sometimes.

i think he was using ATI. though I did have the same initial thought as I think you're having! lol.

I would guess maybe running the dry sump drive gear off the front of the balance places a little more load on it but you wouldn't think it could do this. especially considering how many dry sump RB26s there are around running this way.

Hey Richard /Paul is a bummer to have pull the thing apart so soon but what can you do Is my own fault though As I had an ATI balancer on back order wich I actually picked up on the friday 2 days after track day so only had the standard balancer on there and thought it would live thru the 1st shakedown but it wasn't to be. Let that be a lesson to anyone to be patient and not to track their fresh engine with a standard balancer. I have already got the crank and rods at my machine shop for a repair on the crank snout and to resize the rods at least i was lucky enough to shut it down (thanks to Ruzics EM PRO2 warning function) that it did not damage any of the journell's so at least there is some good news i guess. I plan on having it all sorted before the next track day so will post un update then.

Some pics of the damaged balancer.

being a drag car i have the luxury to run auto shutdown...its saved 1 engine already. Unfortunately being a corner car you cant run one...so you use the next best thing...an EM PRO II...its just paid for itself. How was the pump drive mounted to the stock balancer Daz ? Was it this that comprimised the balancers integrity? Ive seen them crack through the keyway before but in half like that is full on.

Hey mate you are spot on there with the auto shutdown but not the safest option for a cuircuit car. But the as you stated the EM PRO2 has already paid for itself although I was unable to shut it down quick enough to save the bearings (not much you can do when you get a low oil pressure alarm mid corner when you are commited i guess) at least I managed to shut it off before any damage was done to big end or main journells. The drive for the oil pump i was useing was an insert that goes inside the balancer and is held in place with the same bolt that holds the balancer on and then has the mandrel with the drive gear bolted to the insert so there is no extra load on the balancer at all so I have to assume that it just could not handle the power or more so the torque being generated and just gave up the gohst.

Was the old standard balancer mate I would have thought it would have been up for at least a full day being that it came off a reasonably low klm standard unmodded engine but it wasn't to be. Just means a few late nights in the shed and a little lighter in the hip pocket but hey thats cars for you.

I run a 30psi auto shut down on my circuit car and never had any issues.

I also have an electric power steering pump and a manual override thats very easy to access should it be in a trciky situation.

Ive had it throw one dry sump belt and that one time the shut down saved the engine.

In a race situation I can see the shut down being potentially hazardous hence the override. But for a time attack/supersprint type car there is usually plenty of space around you should the engine stop. Steering is the only thing i worried about prior to the electric pump.

i run auto shutdown too...but much safer in a drag car...has saved 1 engine already.

      Mistakes were made, my R34 Story

      (it is a brand new ported mellings pump) I suspect the lack of pressure is due to the leak. It was *not* that low in other logs of oil pressure in the past. It wasn't that hot either, but not far off.

      Would a Mellings oil pump be a viable option  From my time with a LS, and talking to tuners and LS specialists, the "weak" OEM oil pump is one of the first things they recommend to swap out if I was going to give the engine any high RPM I opted for a Mellings high volume, with the high pressure springs and I never had a issue with it Cost wise they are not expensive in the scheme of things

      My new to me M35 Stagea wagon

      By davemoto63 · Posted

      Just bought a 2002 Stagea 250tRS VR-X Four AERO VQ25DET and spent the last two weekends cleaning and detailing it.. still have to do the wheels and the engine bay but the rest of it came up nice. Imported 2011 to S.A. and I'm the third owner since it was imported. I met the guy who brought it over, he went to Japan and picked out the car, bought it and ordered the wheels. He also gave me a list of stuff he did to the car with receipts. Coil overs (I have the original springs), 3" exhaust from the dump pipe back no cat, Custom dump pipe,(I have the original exhaust), Plenum spacer, 18" custom Work XSA wheels (need restoring, I've made a start..), Shift kit put through the 5 speed tiptronic auto, TV and menus/screens changed to english, Australian DTV tuner installed in rear. I've just had four new discs and new pads as well as all the fluids including the brake fluid replaced. I have all the receipts for the last 15 years and the import papers in a nice folder. Car looks great, goes like hell but fuel economy is not a thing lol.. pics next..

      Steps to DIY sanding car back ready for respray....

      By silviaz · Posted

      I ended up in this rut again lol, and used a shit ton of filler. One thing I can't understand is, even after using a big long block and going in long X pattern strokes, I always end up at bare metal again with no filler, and my repair started at one end of the door and now I've chased my tail to almost the other end of the door. I was thinking of hitting the panel with a hammer where it might be a high spot and making everything low then filling it, I did this on a small section on my other door by mistake and I think I fixed it lol. Is this a bad idea? The other thing is with guidecoat, whether it's the powder or spray, after I sand all the guide coat off, it doesn't reveal anything for me in terms of high spots and low spots and makes it especially hard when it's bare metal (at least in powdered form), am I doing something wrong here, or likely a high spot I keep going over and creating valleys? Lastly, stupid question but, is it possible that after sanding if I only sand over the filler area where I know to be a dent that it's impossible for me to dig into that dent? Unless there are other problems which I missed.
