Stewart Wilkins does an Hi Volume pump, brand new for $170.00 including GST plus postage that he uses in all his rally rebuilds. He tells me it is every bit as good as the genuine H4 pump out of the Auto 280ZX Turbo. http://www.swmotorsport.com.au/

It's probably as good a price as you will get in US$ plus postage.

I have a couple of under models, the manual L28ET came out with an H3.3 & some L20ET's came out with the H3.3 or H3.

What's in your motor now???

Cheers, D

L24, running a turbo, I'm wanting to add a oil cooler.

from my research, the H4 comes out of a 280zxt AUTO (these had oil coolers), these are high volume, not high pressure.

I believe the rotor is 40mm not 35 like the normal one, do you know if the Stewart Wilkins has the longer rotor, or a tighter spring to up the pressure ?

Hummmmmmmmmmmmmmmmmmmmmm!

No understand you???

The SWR pump is an High Volume pump & where is there a spring anywhere in the pump???

What longer rotor???

And the spring that I know relating to pressure is in the relief valve.

JFYI .................. The H4 pump is getting thin on the ground & my question to what has your motor got now was in relation to the oil pump, not what your doing???

Hi,

I took this from another site, as you can see, the H4 (left) has a longer rotor, thus moving more oil per turn

( http://forums.hybridz.org/showthread.php?t=150165 )

the spring I'm referring to is the one in the relief valve, I believe some have a higher pressure spring, thus making the pump , pump at a higher pressure,

I need to look at what pump I have to see what numbers are on it, but when I brought it 4 - 5 years ago, it was for a L24,

I'll check mine today and get back to you on the pumps, because I have both here.

As for oil pressure, just pack the spring with a washer or two and don't go overboard, it's amazing what one washer will do to the oil pressure. Start with one and see what you get. It's a trick we used back in the BMC A & B series engine days.

Remember where Nissan got their 1200 Bluebird engine from, it was a re designed Austin A40 engine, from blueprints they bought from BMC in UK.

Did you end up comparing them ?

Nigel

I'm going to do it Tuesday/Wednesday when I'm off.

Got to buzy last week, but I found this on ebay USA.

i have an h4 pump

its ok needs rebuild (engine siezed) thus it had rubish go through it ..

as is $100 ono?

Marc

I would assume to 'rebuild it' would to be 'replace it', I've used a second hand pump years ago, that's why I brought a new one back then..

Same pump was also fitted to z18et and z24 motors, just for informations sake

Do you have part numbers for these ?

      This sounds very old of me, however since buying the Tiguan shit box, my view on shit boxes have changed.

      M35 Brake caliper replacement

      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
