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.

Cheers, D

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 ?

Nigel

    • @Haggerty you still haven't answered my question.  Many things you are saying do not make sense for someone who can tune, yet I would not expect someone who cannot tune to be playing with the things in the ECU that you are.  This process would be a lot quicker to figure out if we can remove user error from the equation. 
    • If as it's stalling, the fuel pressure rises, it's saying there's less vacuum in the intake manifold. This is pretty typical of an engine that is slowing down.   While typically is agree it sounds fuel related, it really sounds fuel/air mixture related. Since the whole system has been refurbished, including injectors, pump, etc, it's likely we've altered how well the system is delivering fuel. If someone before you has messed with the IACV because it needed fiddling with as the fuel system was dieing out, we need to readjust it back. Getting things back to factory spec everywhere, is what's going to help the entire system. So if it idles at 400rpm with no IACV, that needs raising. Getting factory air flow back to normal will help us get everything back in spec, and likely help chase down any other issues. Back on IACV, if the base idle (no IACV plugged in) is too far out, it's a lot harder for the ECU to control idle. The IACV duty cycle causes non linear variations in reality. When I've tuned the idle valves in the past, you need to keep it in a relatively narrow window on aftermarket ecus to stop them doing wild dances. It also means if your base idle is too low, the valve needs to open too much, and then the smallest % change ends up being a huge variation.
    • I guess one thing that might be wrong is the manifold pressure.  It is a constant -5.9 and never moves even under 100% throttle and load.  I would expect it to atleast go to 0 correct?  It's doing this with the OEM MAP as well as the ECU vacuum sensor. When trying to tune the base map under load the crosshairs only climb vertically with RPM, but always in the -5.9 column.
    • AHHHH gotchaa, I'll do that once I am home again. I tried doing the harness with the multimeter but it seems the car needed a jump, there was no power when it was in the "ON" position. Not sure if I should use car battery jump starter or if its because the stuff that has been disconnect the car just does send power.
    • As far as I can tell I have everything properly set in the Haltech software for engine size, injector data, all sensors seem to be reporting proper numbers.  If I change any injector details it doesnt run right.    Changing the base map is having the biggest change in response, im not sure how people are saying it doesnt really matter.  I'm guessing under normal conditions the ECU is able to self adjust and keep everything smooth.   Right now my best performance is happening by lowering the base map just enough to where the ECU us doing short term cut of about 45% to reach the target Lambda of 14.7.  That way when I start putting load on it still has high enough fuel map to not be so lean.  After 2500 rpm I raised the base map to what would be really rich at no load, but still helps with the lean spots on load.  I figure I don't have much reason to be above 2500rpm with no load.  When watching other videos it seems their target is reached much faster than mine.  Mine takes forever to adjust and reach the target. My next few days will be spent making sure timing is good, it was running fine before doing the ECU and DBW swap, but want to verify.  I'll also probably swap in the new injectors I bought as well as a walbro 255 pump.
