hmm you could be right.. though seems odd even at that.. 5th gear at 80kmh at 12psi still should haul i would have thought.. tho maybe not.. will knock it back into 4th and try again

Only reason why Haltech came up is that's what the tuner suggested, and if it's got local support I was willing to look at it.

Cihan is sounding like a good option, or I'll see how Dunc goes with Willall. As long as someone local can fix/retune it.

Haltech option is a new unit which works with 350Zs, so they figure it'll work with VQ25s using the same trigger pattern. I have a quote for $500-1000, but no guarantees it'll work.

Be vary wary... last time I heard that comment "it works on a 350z, it should work on VQ25DET" it cost Jetwreck a lot of wasted money.

The motors in the 350Z and the NM35's are different and so is the ECU.

My word of advice is.... unless they have done it before (and you have seen the results) don't belive them.. they all lie..

True. reminds me of the guy in UK who was so confident that he could flash our ECU with the ROM they use in the 350Z...

showed him the pin out for our ECU and he said no can do!

Haltech 350z Platinum was used as a piggyback on a VQ25det Stagea very early on (3-4 years ago).

I believe it is a standalone unit on a manual 350z/V35

Results were a bit meh... but only mod was a cat-back as far as I can remember

They're talking this: http://www.haltech.com.au/index.php/product/platinum-sprint-series/platinum-sprint-500

But considering I picked up an Emanage for a third of the price, they haven't given me a good reason to use the Haltech. Sure, if it takes over everything instead of doing the addition/subtraction table, that sounds good. But if you get a tuner who knows what they're doing I can't imagine there'd be a remarkable difference.

Haha, my boost peak is 1.92 bar according to the informeter. :whistling:

The issue isnt boost but air volume and this turbo blows a lot of air. Still a fair bit in the old girl but the engine has been running at over 20 psi for two years now, as well as burning the ethanol.

Ok so i am keen though i have just had a look though no idea where to begin so i photoshopped a pic :)

boost.jpg

Here is my engine bay. Remember i have LPG so may look a bit different!

Now number 1 is the hitachi boost controller.. now that has a single air line to it from underneath the intercooler pipe. from there number 5 runs out of the controller and splits into 2.. one section running to number 2 and the other into a much bigger part of the loom that disappears from view.

As you can see number 2 then splits off 2 more times in 2 different directions.. and god knows what 6 and 7 do!

So what exactly do i do to hook up a bleed valve?

i know i can simply cut the air line to the controller and put the valve in between.. though id like to remove the factory unit altogether.

Little help please :)

1 is a boost sensor not the controller.

6/7is th fuel regs.

your stock boost solenoid is on the right which is out of the pic.

if you want come around to mine and ill hook it up for you.

under '1' plug theres a hose, the bleed valve taps into that

thanks for info Aaron! might take you up on that offer! i am going for work for the next 10 days will hit you up when i get back :)

Also the intake baffle (the dick that hangs off the intake) anyone remove it? any gains?

yup I removed it with my old standard intake....didn't notice any difference.

btw....I found this boost tee to be the best out of all the manual ones I have tried.

      M35 Brake caliper replacement

      By Waders360 · Posted

      I've looked up the parts number (41011AL501). It's around $700 OEM. Usually our Infiniti G35 here in Canada have interchangeable parts with my Stagea but the parts number are not the same. I have looked around and it seems the JDM 2005 V35 Skyline (which is the same as our G35) has the same caliper but I cannot confirm. And I can't find a repair kit. The inner brake pads drags on the rotor, seems to be rusty piston. Thanks for the info by the way

      This coupled with 6-9 speed autos with ridiculously short gearing is why these modern shitbox cars always seem so fast off the line. If it wasn't for those things, Raptors would not seem fast. The problem we have is there is a driveability gap between a more gentle take off and a wheelspinning sideways launch. The difference between ankle flex required to achieve one and ankle flex required to achieve the other is about 0.5°.

      Yeah I think I'm also with the opposite here. It's 'hard to keep up with traffic' because in the real world I'm accelerating with 15% throttle and they are pinning it. It feels like I'm being an overt dickhead at anything above 15% throttle, so the car sounds like I'm being an overt dickhead to keep up with/get ahead of traffic when I'm really just trying to drive with traffic. There would be no issue 'keeping up with traffic' if we used the same level of throttle input/aggression to drive around. People really do just drive around with their foot nearly pinned in econoboxes.

      To be fair it's the other way around. 300kw is boring in a modern Golf or BMW. They are so competent / well-engineered / devoid of emotion that you have to go stupid fast to feel anything. Whereas the <300kw RB still makes all the right noises and it feels good to drive. Can pull off at the lights with the turbo whooshing and the blow-off pssshing and feel like the coolest kid on the block. Just don't look to the side where you'll see the bored housewifes in their shitbox Yaris/Corolla/Camry that kept up because you didn't go fast at all

      300kW is so boring in a Skyline, you'll get spanked by someone's mum's Golf with Alibaba pipes, and an email tune.
