J spec are offering one for racing - CAMS licence required.

I can be there by midday.

I think I'll buy shares in Royal Purple gearbox oil!!! There's gunna be a rush...........

Check your hoses for splits, you could have a leak. Do you have an am gauge installed?

You don't buy plugs with a smaller gap!!! You buy plugs and then use feeler gauges and set the gap by knocking the tang on the plug in or bending it out a bit. Or you could just do it to the plugs you already have in it. A set of feeler gauges will set you back like sub $5 [you can get a bigger set for $30 approx.]

Haven't done it in 1ts or 2nd, but it doesn't do it in 3rd, and as I say if I ease it on and build up slower like floor it over say 10-20 seconds then it doesn't do it in 4th either, only when I floor it instantly. But I reckon its the tune!!

FPR cos my std one was supposedly leaning out, I don't need the rising rate, just a good qual fpr, and SARD are OK. And thanks to all that responded, I didn't want to say what I thought cos I was after an unbiased opinion. But I agree with you, I'll have to have a look at the map and knock some timing out in the range where it is pinging. I intend to get it on a dyno at another shop as well, and get a second opinion/tune. As an aside - the first time I got high knock levels I thought it was maybe triggered by a random thing eg bad fuel, injector, other stuff...........but the next time was different fuel, and I couldn't feel anything wrong with the car, no miss or stutter, so I agree with everyone, its in the tune. And Mafia - you run with MI, I don't, I might one day soon, but not yet, one step at a time for me, I'll get this setup sorted first. Dale, I can do that, but there is nothing remarkable about my engine bay, its got some decent stuff in there, but its not a show car, its not polish and chrome, you'd see nothing unusual.

What boost level are you running and what knock/ping level do you have? I've got spikes of 130 if I hammer it [foot all the way down] in say fourth gear and 3-3500 rpm, 80 to 130km/h overtaking maneouvre, doesn't happen in 3rd, I'm running at 1.2 bar. I've seen it twice now, so it's definitely out there. I was wondering if anyone else has this problem? If I drive it normal and ease the power on a bit more progressively, I'm lucky to see a knock level of 10 to 15. Std 2.5 motor, fmic, power fc, hks cast low mount extrude honed, hks 40mm wastegate 18psi spring, 550 injectors, split dump, tomei 256/8.5 cams, hks hyper exhaust, pod, sard fpr, z32, boss cat, nismo pump etc etc. 275rwkw. I was wondering if its tune, too high boost level, or because of a fuel starvation [need a surge tank, long shot this one]. I would prefer not to have to touch the motor [thick head gasket, forgies etc].

If its a Saturday arvo I'll go. I'd like to check what UAS got on their dyno.

Tapping is the back door or bedroom window! Knocking is the front door! Injectors, manifold/turbo/flange leak, tappet clearance all usually a tapping sound. Easy enough to trace eventually.

Catch can and mats sold!

Where's the vid??? Sure your laughing, but thats pretty selfish, we want to laugh too!!!!

Catch can in the process of going to someone else, but I'll get back to you if it falls through............sorry best I can do.

As above, Z32 AFM sold.

PM sent.

Heat wrap sold.

Slide had the best price that I could find [and that included Nengun and Greenline]. link: http://www.skylinesaustralia.com/forums/Sp...36-t188698.html

Plastic inner stone guards sold.

Apexi N1 front pipe sold.

If its built in then its not visible..........looked like a normal say 3mm hole to me at the feed. What size is the built in one?

Supporting your argument - And you could maybe take another 20 or so off for octane??? Although some servo's now sell 100+, it isn't as common in Oz.
