Hey guys.

Can I run 264 9.00mm lift hks cams 2202 RN175 with standard valve springs. Where could I get these cams in Australia?

That's a reasonably high duration, meaning you will be revving it.

In which case you will probably want better springs.

You can run an adjustable exhaust cam gear with stock cams, which will give you an improvement in mid range power. But as a mechanic id never fit cams without putting in heavy duty valve springs. It pretty much goes hand in hand. You want cams, you must fit valve springs. Yes the HKS cams are drop in meaning they'll be ok to use with your stock valvetrain/head (excluding valve springs) The stock springs wont cope with the duration/lift of the HKS cams.

I hope you don't want to put in cams just so you can have am adjustable intake gear.....

That would be an ultimate fail, as vct is way too good to lose, and the stock gear is adjustable anyway (on a neo that is, not sure on pre neo, adjustable from the back but easily modded to be adjustable from the front.)

Why do you want cams?

What do you use the car for?

i had hks cams before and i want to delete vct ro run 26 covers. I want the car to make around 550

DONT DELETE VCT.

Especially just to run 26 covers.

That's plain stupid.

People with rb26engines would kill for vct.

Yeah seems silly to get rid of it just to run different covers. You can make the 25 covers look good

Or you could probably get the 26 covers modified to have the hump for VCT put in them

The power will be alot nicer if you keep VCT

      Find out what RPM it was idling at with the IACV unplugged. It's very weird that the rpm didn't change at all, and then it stalled. When it stalls is it nearly like a switch off, like you've turned the engine off? Or is it more stutters and sputters and coughs to death over a few seconds? Or does the RPM just slowly keep going down and down? Have you done a test of trying to start it with the AFM unplugged? Does it still die?     If you Follow Josh's advice on using Nistune to check the voltages (which is a perfect method!) if you see anything out of wack voltage wise, THEN get the multimeter out and read the voltage directly at the sensor. If the two vary, then you're now looking for a wiring issue vs a sensor issue. So be aware, what the ECU sees, may not be what the sensor is actually saying too...

      RB25DE NEO with Haltech ECU

      You very likely need to get it on a dyno and tune it. My assumption is, you've got an RB25DET tune in it, which has a different manifold, different injectors, and different cams as a minimum. What O2 sensor are you running?   When you say it runs extremely rich from idle all the way to redline, is this just free revving it you see that?

      RB25DE NEO with Haltech ECU

      I seem to the be only person that is using a Haltech 2500 on an NA motor, I've installed a Bosch DBW throttle body to the OEM intake manifold and am having problems maintaining AFR even with the wideband o2.  It will run extremely rich at idle and up to redline, but under load it will go extremely lean in the 20s and i'm essentially having to rev it over 4k and feather the clutch to get it up to speed.  I've read a few other threads of about the butterfly, it seems removing the vacuum to it is supposed to have it remain open, i've noticed no difference under 4k with the vacuum line to it plugged.  I'm hoping someone here has had luck using the NA manifold with Haltech, and if they happen to have a tune for it.

      Could it really happen......

      I don't know any details, but I really wouldn't be surprised if they do it as a LHD only version, at least initially.
