Correct. Oxygen is nonflammable too. However, what these gases are very good at is supporting explosive combustion, all they need is an ignition source and a saturated concentration - think dyno cell full of G size bottles opened fully and then add a red hot manifold. I'll be the one standing over the road Next time you're at the drags and you see someone purge their nitrous system, don't stick your head near the stream of purged N20 smoking a cigar... unless you want to look like Micheal Jackson

Just buy a heap of G size bottles... and while the import cars are running, open all the bottles into the dyno cell - extra power and a nice relaxed and cheerful mood for everyone It might cause a fire, but that just makes it easier to cook the BBQ food.

I couldn't care less what kind of performance car a person owns. If they're a genuine car enthusiast and they want to chat about their car, or my car, then full credit to them. But if they're nothing more than an arrogant knob-jockey, be they a Ferrari, Skyline, Torana, Porsche, Supra owner etc. I'd rather move along and find something better to occupy my time.

No worries at all Tangles, happy to try and help make the engine building journey smoother for you. The standard RB25DET bottom end can certainly support over 300rwkw - I've witnessed a few that have managed this feat. However, in most of these case, if not all, they had reduced compression (via 1.6mm metal head gasket etc) to give a little bit of 'margin for error'. Having said all that, the cylinder pressures and temperatures that come with a 300rwkw engine means the standard cast pistons will not tolerate even the slightest hint of detonation, detonation that can come from a host of variables - fuel quality, injector flow variations, cylinder temp variations and so on and so forth. At the end of the day a poor tune can just as easily lead to detonation killing expensive forged pistons. But it's those minor variations, that can and do occur, that a decent forged piston may cope with long enough to allow the issue to be resolved without doing any serious damage, something that the standard piston ring-lands will not survive. Rods, on the other hand, are more likely to fail due to rev's at the 300rwkw mark. Keep the rev's under 8000rpm (say about 7800rpm) and the standard rods will last for a reasonable length of time at 300rwkw. Mind you, give the price of a set of rods these days ($600-700 for Spool rods)... I'd suggest a three possible approaches to the making the most of the head upgrades: Basic) Drop compression a smidge - via a 1.6mm head gasket Medium) Head gasket/o-ringing and forged pistons Advanced) Do all of the above + rods and fasteners

Ken/PIMPED, 400rwkw using 550cc Sard injectors... that's what i call pushing the limit! I'm going to do my best to make it to this dyno day, as it sounds really interesting. It'll also be interesting to do a rough comparison (power curve, peak values, turbo response etc.) with my own dyno runs on Shaun's dyno - there's about 90+ of them saved on the thing ha-ha. I might even have the tuning finished by then and could try and help bolster the import figures - I 'may' be able to offer low 300's at the rears - best of 302rwkw so far. It might squeeze out 315-320ish once the cams are set-up and a few more pounds wound in. What we - the import team - really needs is for Darren's R31 to be up and running - 550rwkw would help push the total up nicely.

I can vouch for, James (not Jason ) from Nisspeed. However, he is usually one very busy man. For the cost of a decent set of pistons and rods these days, in all honesty, I'd be doing the lot now - while the head is off. If you don't have the extra $ then save a bit more and then do it. If you want to make the most of the top end upgrades and have piece of mind with that additional torque, then at least do the pistons/rings etc. We all know that standard RB25DET ring-lands are like Amy Winehouse (sp?) they love the crack

Joel, that's a fair effort in a few short years. I'm impressed! If I recall correctly, you had your RB30DET built a little while after my 2.5L. In that time I've covered some 5,000km, if that. Admittedly 2 of those years it did more travelling on the back of flatbed trucks - thankfully by choice, whilst undergoing various modifications. A .6 housing on a manual RB25DET is 'wheel-spin city', even with good tyres. It can be fun though. My Stage 3 0.63 Turbonetics rear housing comes on hard, really hard, in the low 4000rpm range - even a traction friendly diff' angle and camber set-up won't stop the 275/40/17 MT ET radials from rotating faster than their cousins up the front. The HKS 3037 Pro S 0.68 housing will mean you'll have plenty of fun in 2nd gear during daily driving use - nothing the right foot can't control though. The 0.87 housing would be my personal choice, due to the extra top end power potential, but that's only because I wouldn't use it as a daily driver. The 0.87 is good for ~310-320rwkw. Also, I'd agree with you, Joel. The GT3540 0.63 on a RB25DET will probably see peak boost by ~4000+ (in 2nd). It should also provide the kind of torque curve that produces 3rd gear wheel-spin. I like 3rd gear wheel-spin, it's nice

Hi B-Man, quick bit of info' you. My work posted me from NSW to SA back in 2001, at the time my NSW rego papers listed me as the owner and all details were to stay the same - other than a new SA rego' number. Regardless of the above I was still required to present the car to the Sturt inspection station - I elected Sturt as it seemed the logical choice for a Vehicle Identity Inspection. The Sturt inspector/s still double checked the VIN details and engine number to verify all was in order. Even though the sole purpose of the inspection was to verify the car's identy, the inspector still cast an eye over a few of the basics - pod filter was okay, intercooler was fine - but there were numerous things he didn't check. In the end the only issue was my 'illegal' genuine Momo Race steering wheel. The wheel was purchased new from Revolution Racegear and was indeed legal according to the details stamped on the back of the wheel and ADRs. I didn't bother to complain, I just swapped the wheel over as request and an hour later I was good to go. One point of note: I wore my work uniform - Air Force - to the inspection station and treated the inspector as I would expect to be treated in return. As an expat NSWman I took a while to adjust to the slower big country town feel of Adelaide and SA in general, but now I really like it here. The lack of regular drag strip is the biggest downside from a motorsport perspective, hopefully this will be rectified in the coming months/year. Plenty of decent workshops, performance parts vendors and automotive events/shows etc. As for choice of locations to relocate to, it's best to take a visit and see for yourself, that's what I did. Cheers, Matt

Have heard rumors - from a guy that was there the day the TGA footage was filmed - that John Bowe was dressed up in an all white race suit with white helmet in hand. Make of that what you will.

Then again... VW have done a very reasonable job of making an engine that's short on displacement punch well above it's weight. VW call it TSI, but it makes more sense when I say... a supercharger and a turbocharger combined to work as one. The VW Golf GT/TSI runs a 1.4L four cylinder TSI engine that makes 125kw and 240nm of torque, the bulk of the later at just 1500rpm till 5000rpm. Driven 'normally' it can also return figures of under 6.0L/100. It's even more fun when it comes with a DSG gearbox. Not exactly R35 GTR territory, but good for the daily commute, very impressive economy (handy when paying 1.50+per L) and much quicker than a few fleet Commodore owners were expecting

Will, that's exactly what Shaun & I were talking about yesterday. I've only just learnt that E85 exists - been hiding under a rock. It might be a case of switching between E85 and pump 98 tunes, I'm not sure. Example: in goes a tank of E85 for some fun, run it low, in goes a full tank of pump 98, switch tune over to 98, fuel system has mostly 98 in it and can sit in the shed till next time. It seems good in theory. Then again I could be way off - Martin would be the man to confirm that one. Obviously the injectors need to have enough capacity to support the E85 and fuel pressure will need to be spot on etc. One thing is sure, we'll certainly do a Martini 110 tune. Drove the car yesterday and was able to use full throttle for the first time in about 2 years! It does in 3rd what it use to in 2nd. I like it. I notice someone mentioned Skylines Downunder in this thread. Good old SDU. I can still recall registering on SDU when it had about 100 or so members - in about 1997 or thereabouts. Times have certainly changed! Anyway back on topic; Can't wait to see what a tuned, exhaust upgrade, boost increase R35 GT-R can achieve on the drag strip. It's only a matter of time till people start run high 10's with a mild R35. Events like Targa West and Targa Tas are also going to be interesting as more R35's start popping up.

Yeah, there's a few of the 'originals' in this thread!

Haven't seen you for a while, Daz. Good to hear the new set-up is coming along. 500-550rwkw on E85 should be very tidy work! I might have to look into E85 for mine - not quite in the same ball park as John and yourself though! I'll be happy with 320rwkw. I think the R35 still takes the cake as a total package though

The cross-over pipe does add a few extra minutes - my original 20min estimate didn't account for the cross-over pipe as I no longer have to deal with one. Just one of the bonuses of a forward facing plenum. However, I still think removing the coil packs and replacing them is a simple 20-30min job. If I had never done it before and was using this thread for assistance, it would probably take me an extra 5mins.... spent watching rad32's avatar.

A police R33 Skyline, pulled over a Commodore, on Anzac Highway!? I think you might need to ease off the coffee, Flick

3 hours is a hell of a time estimate for changing a set of coil packs - 3 hours! It might take that long if you did the whole job with your tongue. About 20mins if that.

Considering the situation, this is a very positive outcome. Well done to all involved. I look forward to getting both hoodies and the new one having a much improved finished design.

If the options are limited to, John keeping his R33, or selling it to help with the purchase of a new-ish R35 - I reckon that old R33 wasn't a bad car and hopefully the new owner makes the most of it

Considering the GTR has been released on a global scale, for the first time in it's history, I'm tipping that we'll be seeing low 10/high 9 second drag versions sooner than people think. Not only are the Japanese workshops already starting to develop upgrades, but this time the massive US market are gearing up to put runs on the board.

Likewise, mate. It had been a while since I'd ventured down to Willall. A lot has changed! It was good to catch up with Martin too - it's been about 2yrs. Although I had already seen the R35 in the flesh earlier in the year at the Adelaide Motorshow (where I caught up with Munro) getting a chance for a closer look at the car has confirmed in my mind that the new GTR more than lives up to the hype and expectation. It was only after Martin pointed out how large the R35 looks when compared to the other 'supercars' present (997 911 Turbo and Gallardo) that I realised just how big it is - mainly due to width. The smaller features of the R35 that Martin talked about were really interesting and I am keen to see just how much can be extracted from the car with the standard ECU running the show. It certainly didn't take the guys long to begin dabbling with upgrades - nice work! The exhaust upgrade has already transformed the aural presence of the R35. At the end of the day, I struggle to think of another production vehicle that can deliver so much for such a relatively modest price tag. I'm hoping the humble offering of a test run in a twincharged Golf GT DSG and TRD Aurion will equal a brief on-road R35 experience

Hehe. Yeah he was telling me. Small world.

I would also like to acknowledge the effort in organising this group buy in the first place. It is often a thankless task. Well done!

$56.60 transferred as promised.

I'm happy keeping mine dead stock.

Try only covering ~50km in the last two years - 50% of which was on the back of flatbed trucks. Awesome for fuel comsumption, but no fun at all. That's the price of you pay for lots of modifications all in one big hit. Nothing to do with spotting Skyline's, but I thought I'd just add... I love what the text message has done for the English language.
