They had exactly the same part number from Nissan, when I ordered new headlights for my GTS-t ages ago...

288 degrees duration, 11.35mm lift??!?! These are JUN's biggest camshafts Holy hell, they're some SERIOUS camshafts You'd better be aiming for about 900hp to consider these!!! Also, regrinding them is ridiculous, you'd be losing JUN's huge amount of R&D into matching lobe seperation, intake and exhaust durations and exacting lift measurements, and making them all work in tandem... That's what you're paying for in these magnificent camshafts!! Not the metal composition... I just wish I had a GTR that these camshafts would suit, because this is an awesome price...

I'm going for the week with Yang, Helen and a few others, but Franky couldn't get the whole week off, so he's going down for the weekend, so we'll meet up with him there I can't wait :burnout:

Good to see all that snow!!!! I can't wait to go to Perisher next week!!! YAYAYAYAYAYAYAY!!!!!

:werd: I should have bought SWOOP :uh-huh:

You guys are all slarts. Now shuddup and go do some work

There's absolutely no difference. Since Garrett manufacture the turbos for HKS, they MUST be the same.

Me?? Mate, I think it's YOU that should "get over it ay"... You caused an accident, because you obviously can't judge distances, and you call the innocent party a "****ing taxi driver"

If I read that right, you hit the taxi? Why is he a "****ing taxi driver" then? You're the one that caused the accident?

I spoke to Brian (Integra Owner) and he said there was some electrical issues... Starter motor didn't even turn over. There was nothing wrong with the engine at all apparently... .......... oh, and btw, it's turbocharged.

a) 150-200km/h??!? Suck sh1t. Serves them right. B) Not speeding? Bad luck

Yeah..................... Great................. Now who is going to buy these tyres off me?

It's late, and I'm tired, so perhaps I didn't quite understand that properly, but it seemed to me you contradicted yourself a few times in that post :confused: Basically, in theory, the turbo spools up by exhaust gasses spinning the shaft... The more it spins the shaft, the more air the turbo will pump into the engine, and the more air will exit the engine, turning the turbo faster, in turn forcing more air into the engine, etc ,etc etc... As you can see, it's an exponential rise in power gain, which is theoretically limitless. Of course the size of the turbo and efficiency deems that incorrect, but you get the idea. Now since we have an exponential curve, that means we need to limit the power somewhere along the line so we don't blow up our engines. In comes the wastegate. Basically all the wastegate should do, is wait until you have reached the desired boost pressure, then open up and let the EXCESS exhaust gasses bypass hitting the turbine wheel, prohibiting it to spin faster and making more boost. Pretty simple design. (Pity about wastegate creep ) So back to our exponential curve. The actual shaft speed is exponential, and hence the boost curve is exponential... This means that as you continue to spool up the turbo, the more boost your turbo is making, the faster the boost will increase. e.g. At 0.1 bar, it would take 2 seconds to hit 0.6 bar but at 1.2 bar, it would take only 0.5 seconds to make the same 0.5 bar increase to 1.7 bar. Makes sense? Basically as you build boost, it will build it faster and faster as you go along (exponential curve). Phew. So back to your original comments about boost, you're absolutely correct. If you set your boost controller to 0.5 bar, it would take say 2 seconds to hit 0.5 bar. If you set your boost controller to 1.5 bar, it would STILL take 2 seconds to hit 0.5 bar, and an ADDITIONAL 2 seconds to hit 1.5 bar... (Completely arbitrary values, but you get the idea I hope)... You know what, I don't even know why I'm posting this. After re-reading what you wrote, I realise you already know all this. Oh well, I sure ain't gonna delete it, so I'm just gonna press the "Submit Reply" button now.

Traction control?!?!?! Traction control is for CHEATERS!!!! Lets see you launch by controlling traction with your two feet!

I can organise freight to Singapore no problems... I have no idea how much freight would be... [email protected] to discuss the price, but no, If you want a $2000 clutch, this isn't the one for you.

Uh huh............ Right............. And what would "full boost" be? 1.0 bar? 1.2 bar? 1.6 bar? Not aimed at you in the slightest but to everyone in general, "full boost" is the dumbest term EVER. Everyone runs different boost with the same turbos, so that term is completely and utterly redundant and useless.

I'll be along.. not sure if I'm going to do any passes just yet...

Any 16x7.5, 16x8, 16x8.5 inch rim... R32 GTR rim is PERFECT... 16x8 inch rim, forged, lightweight, and looks good...

Still for sale

a) they're not more efficient, they have different compressor/exhaust wheels that SHIFT the efficiency band to higher boost levels. B) you don't believe that an HKS GT2530 would make more power at 1.6 bar than a Garrett GT25 at 1.1 bar??? Or to illustrate the point further, a Garrett GT25 at 1.6 bar, where it would just be blowing hot air and making less power than at 1.2 bar? That's interesting, I didn't find it that hard to believe. If you believe that the HKS turbos are optimised for higher boost, the fact that they produce more power makes perfect sense to me. And I agree with the others, although there may not be any direct "GT30 on the car... dyno it, take it off, HKS GT3040 on the car... dyno it" comparisons, I think the fact those "old wives tales" have considerable weight behind them, especially when you hear the same from all japanese tuners who have been playing with these Garrett/HKS turbos ever since the conception of the RB range of engines. Steve, I have a 0.87 turbine housing, and I hit 1.2 bar by 4000rpm... That's all I have run, but I would assume 1.8 bar by 4300-4400rpm... I know, this turbo is wasted with stock internals

If you bought it from GCG, I'd put money on the fact that it isn't an HKS turbo. To whoever asked, you'll be VERY hard pressed to find the compressor maps for the HKS turbo range... They are very closely guarded secrets. As to how do we know that they're more efficient at higher boost levels? From personal experience, from the thousands of people in Japan who use these turbos, and most importantly, from what HKS dealers set boost at for their customers in Japan. That's the main difference between Garrett and HKS turbos. Their compressor and exhaust wheel designs. Garrett are designed for lower boost power, and the HKS turbos have their efficiency range shifted to higher rpm to produce more power... People say the HKS turbos spool up faster than the Garrett equivalent, but I have never seen a back to back test to prove that. All I know is that the relatively big HKS GT3040 on my car spools just as fast than stock GTR turbos and makes a crapload more power.

$1200?!?!?!

Did you get an HKS GT2530 or a Garrett GT25? Because: 1. If it's an HKS GT2530, you're going to want to run about 1.5-1.6 bar through it to make it sit in it's efficiency range. 2. If it's a Garrett GT25, 210-215rwkw is probably the absolute maximum you'll get out of it, if you're set it up properly.
