Al im sure you've probably mentioned this somewhere before, but what exhaust A/R are you using? 1.06??

Wow what a power curve What do you think you'll make with the 3076 at higher boost Al?

Dissapointing, but most of us know we'll spec it up, or if not above the Japanese spec with aftermarket parts anyway...

Porsche did it... so have Alpha Romeo and a bunch of others... if not 90% of transaxles...

All of those brands are excellent so I would choose the cheapest one

Few more camera phone pics

Sorry but to fit clear tail lights you fail Skylines and fail at Life...

+1 I used this to remove some old for sale stickers off my plastic motorbike visor after I purchased the bike. Worked fine for me too

The larger one should flow more I'd be interested to see how you go if you end up buying the gears and having them reproduced on a CNC machine (assuming thats what you have in mind)

Greenline.jp have them

That RB20 looks right at home in the Bimmer engine bay. Just a thought re: the sump modification, why not look at running a dry sump setup to aleviate the cross member, and any possible height issues with the RB30DET?

No the RB30 is 38mm taller

Yes it should be fine to do so.

Well I guess this means every 14 yearold schoolkid is going to be wanting one (and joining SAU)

As everyone else has said run ultimate or any other 98ron equilvelant (vortex 98 for example)

Wait, you said your Oil pressure is 3/4 when idling hot? That doesnt sound like a spun bearing...the pressure is way too high when hot. There must be something blocking the flow somewhere. Im guessing you can't see oil being thrown around when you take the filler cap off?? There's some galleries behind the oil cooler, and to the head that could possibly be blocked. It could be worth trying the oil flush next. Basically I'd try to eliminate everything you can before tearing the motor apart.

If thats what it is.... New main bearings

If nothin else I like that they're using a dry sump setup

It's the AAC valve (Auxillary Air Control) working. Its the valve which bypasses some air past the throttle body when it is shut. If it becomes more of a problem, take it off and give it a hit with some carby cleaner.

Holden Special Vehicles today unveiled a seven litre program at the Melbourne Motor Show, the last instalment of the company s 20th anniversary celebrations. The car to be known in its final development stages as the W427 is finished in the same Panorama Silver paint scheme as the original Group A SS VL Commodore, released at the Melbourne Motor Show of 1988, exactly 20 years ago. HSV Managing Director, Scott Grant, said the W427 was a tribute to how far the company has come in just twenty years. To be able to produce a vehicle of these proportions is truly remarkable, Scott Grant said. The W427 will be quite possibly the fastest road registrable Supercar ever produced in Australia and among the quickest anywhere around the world, he said. While power output figures are still to be confirmed, the W427 is likely to produce in excess of 370kW of power and 640NM of torque. It will also be one of the safest cars HSV has ever put on the road, Scott Grant said. A new six piston front braking system will provide a 50% increase in pad area, while the W427 also receives a revised ESP calibration, six air bags, improved handling and new Magnetic Ride Control settings. The W427 receives a bimodal active exhaust system to improve noise quality and back pressure management. Styling and design highlights include an all new front fascia, a three piece carbon fibre rear spoiler, 20 inch machined faced alloy wheel, unique exhaust tips and red leather interior. Scott Grant said HSV would be introducing a unique customer relations program to accompany the launch of the new vehicle. The W427 will only be produced in limited numbers and we want to reflect that exclusivity in how we connect with our Supercar customers, Scott Grant said. This program will see the LS7 engine being fitted at Clayton, along with the dry sump system and a range of other engineering features. We are looking at opportunities to allow owners to visit HSV and view the unique manufacturing process that goes into building this car. The W427 will go into production in the middle of the year and will be available for sale in dealerships in the third quarter of 2008. Make no mistake, while the specifications of the car unveiled on the stand today at the Motorshow may change slightly between now and when production begins, this car is destined to make as big an impact as the original Walkinshaw twenty years ago.

Yeah I think that would be the next best thing to try if theres still valve train noise... as sticky lifters are fairly common. Personally I'd go with something like Nulon Lifter-Free if it was me but its up to you... Goodluck mate.

Nissan recommends 7.5W 30 so try to run something closer to that. Thicker oil means higher pressure and less flow. What your describing here sounds exactly like that.

I think the viscosity of the penrite 15 is somewhere around 15W 60? The first cheap thing to try would be to run a thinner oil... somewhere closer to 5W 30 since DOHC heads need more flow to the head..

Do you stil have oil pressure?

The roof line reminds me of an BMW M3... Hopefully the Racing harnesses are saying something about its handling too
