PM-R33

Some of the R35 GTR boys or some of the drag spec built R32 GTR's I would think.

Nah as far as I am aware they don't. I had my fluid go down low one time and didn't see any warning light.

Mmmm that looks yummy, what the hell is it?

It's a piece of piss to get rid of. Unplug, get rid of HICAS steering rack, put in lock bar, tidy up wiring. Pretty sure there is a DIY on SAU for it. Yes you will need a wheel allignment.

What was the last thing you did to the car before the light started coming on? It means it is getting an error of some sort and going into its failsafe mode. You need to work out what is causing the error. I once had it happen when I shorted the speed signal wire, kept happening. Simply reset the factory ECU (disconnected the battery over night) and hey presto was fine again.

Can you post a pic Hamish? Never seen this sort of thing your describing, only the side bolster going flat.

Righteo the package is getting taken to FedEX tomorrow personally by the guy I have been dealing with (not waiting for FedEX to pick it up) and they are going to send it the fastest way possible (not sure what that will be). So hopefully have a new tracking number within the next couple of days. Yeah my mum mentioned that the other night lol. Hopefully shall be ok..

What workshop? Or is that a secret?

While it's a good idea in theory the main problem is you are letting the public vote on modifications. The public is 99% tools that know nothing about cars. Therefore on this alone the car will end up looking like shit with 24" chrome wheels, multi coloured graphics, neons, 100 subwoofers, 10 downlights and a snakeskin interior. At the end of the day i'll still watch how it goes just to have a laugh at how the car turns out. $15 says im right *see what I did there?*

PM sent.

Yeah i regret having kept an up to date record of what the car owes me. I really hope Matt didn't keep the receipts. That shit just always hurts to look at. Ignorance is bliss

My god that fits in there good!! I think you are onto something here! $100 says there will be group buys next year for 350Z dashes on the forum

Live life on the edge boys, if your engine aint on the verge of shooting a rod you aint living. I like this thread.

I have a complex mathematical theory that only I can understand, here it is: Latitude: 19° 15' 0 S Longitude: 146° 48' 0 E These are co-ordinates of Townsville and I believe there to be a god like creature in the fabric of time that is f**king with our two Skylines causing them to ping. That is all.

Oh ok awesome. That is very good to hear. Like I said, the CR idea never popped into my head until my tuner said it may be a cause. It started making a bit of sense but I had no idea how much machinist's take off on the head, hence why I started this thread.

Hmm ok interesting. Will look into that, cheers. The more ideas the better. I really do hope it is something simple and not the CR as I really don't want to take that head off again. If we can't sort it out here in Townsville and The Mafia in Mackay can't work it out it's road trip time to a bunch of Brisbane workshops, so you may get a phone call one day

Sorry man, what's the trigger angle? It's using a Microtech LT12S.

Another thing we thought of and checked with a timig light. Even re did the base timing (locking it on the ECU and redoing it) just to check but it's not that either. Checked the CAS aswell as I have had one die on me in the past, wasn't that. The Mafia on these forums has said he will have a look at it when I take it down to him in Mackay or something. Just trying to rule out this CR thing as there wouldn't be much he could do if that was indeed the problem. Unless the harmonic balancer is f**ked and actually aint showing the true timing location at the bottom of the belt. Suppose it wouldn't hurt to take it all off and check the actual timing belt location on the crank snout.

Yeah running ARP head studs and it was the first time the head had been removed, so first time it has been resurfaced. I'm thinking that yeah maybe a bit of meat was taken off the head. It's not so much about the boost, it's the fact the car simply won't take any timing to make power. The strange thing is when the head first got put back on it made more power throughout the rev range (as in i got a dyno chart with more power). However with that same tune it was detonating hard and really it didn't have much timing in it and had quite rich afr's. It's not so much about me wanting to drop the CR, it's more about trying to get the CR back to what it was if it is indeed higher than what it should be. Is there a way I can tell how much has been taken off the head? What if it has been more, ie 10-20 thou? It was a fairly reputable place that did the head so I'm not to worried about that. Like I said it is mainly the fact we can't run timing into it without it detonating. I mean NO timing what so ever. We than tried running my new nitrous setup (as that was the point of getting it redynoed) and the car absolutely hated it, kept detonating no matter what AFR or what timing was in it (the jets were even ran on the rich side but no luck). To me everything is pointing to the CR being a lot higher than 9.1:1 the more I think about it. Would these symptoms be correct in thinking that though? As in lets assume there was a bit taken off the head and I have bumped up compression to something silly like 9.4:1, with something like that it would keep detonating on high boost with timing put into it wouldn't it? Also since I havn't mentioned it, the camshaft timing has been checked a handful of times as that was the first thing I thought of and it really does all appear to be spot on so I don't think it is that.

Ok that sounds very interesting. So when you say the distance between the piston and cyl head at TDC, this would mean a high CR correct? See when you say they take of 0.25mm when resurfacing the head, this means to get the same CR I should have used a 1.5mm (1.45 to be exact) head gasket? So in essence my CR would be higher tham 9.1:1 yeah? An NA RB25 runs 9.5:1 correct?

Nah the block wasn't touched. I am on the verge of pulling the head off again and putting a thicker gasket into it. But I would really hate to go through that pain again if that aint the problem.

Hmm that does make sense I suppose. Well the knock part of it is the main reason this whole thing has come about. My engine simply won't take any ignition timing without the thing starting to ping. Due to not being able to run ignition timing the power level is absolutely terrible at the moment and yet nothing has been touched since the head got done. My tuner keeps thinking that the comp ratio is a lot higher than 9.1:1 and hence on boost levels close to 20psi is takes next to nothing to knock. I don't know. It really doesn't make sense to me as we made good power on this head, yet now it suddenly is crap with nothing changed and after checking every little thing nothing can be found to be wrong with it. It even sat at my mechanics for a week and they can't figure it out either.

I don't get what you mean? Both holes are next to each other under the factory airbox. One pipe goes in, one pipe goes out. Just follow the pipes.
