Well if you hadnt noticed your thread says im after 350rwhp. Your asking the wrong questions.

Get a suitable turbo first!

Well according to the workshop there are cars (r33) making 358rwhp with the same hi-flow turbo with supporting mods (which I do have btw), so I think it's fair for me to expect 350 out of mine too...

And I can't justify spending $3000 - 3500 on a new turbo setup to achieve 350rwhp..

The fact is it's making 300hp at 15psi (boost drops from 18 to 15), and I think HKS actuator is the way to go atm... at most I lose $200 and still have 300hp, but if I'm lucky it may hit 320-330 mark ;)

ECU???

It's a Remap ECU ..done by Toshi (I'm pretty happy with the job he done)

Do people know how much you can get out of a high flowed r33 turbo? Mines a RB25 and im making 290Hp at 12psi. But they guy that tunes it said he wound the boost up too 20psi but only got about 10 more Hp. Does this sound right?
SO is that to say if i have the same mods and high flow turbo and im not making near that power with more boost then my tuner did a crap job?

290hp @ 12psi sounds right, but 300 @20psi??? something's wrong some where.... I'm not an expert, but I don't think a hi-flow turbo can hold 20psi, yours must be dropping boost at high rpm just like mine.. as far as I know, the ignition timing is involved here as well

      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.
