WTF, how did that even happen

Meh, more parts at the wreckers or gumtree for me to browse through 

And the more that get written of the more mine goes up in price, and for a Commodore, that is weird, but true

I sold my VT2 SS LS1 6spd with usual mods (headers, exhaust, intake, tune) around 8 years ago. Was on the market for 6.5k for around a year before it finally sold for $5600. Struggled to even get anyone to come look at it.  I see guys asking 15-20k for them now and most of them look clapped out compared to mine.

Ah, the times we're living in.

The Cruise Ship is in dry dock (Autotech)

It has developed a knock in the steering, mainly on right handers, I had a look, got the shits rolling around on my back under the car without finding what is was, so sent it to Autotech so they can put it up in the air and have a good look around, I'm guessing its a rack bush

While it is there I've asked them to do the front main seal, which currently losses oil at the rate of about 1 drop per week, which is annoying.....so.......seeing though the harmonic balancer needs to be pulled.....I've asked them to fit a Melling 10296  high volume pump, because.......why not

Nope, I has blower, so I don't need no stinking turbos

well.....

 

you can haz both? supercharger with twin turbos.. will make all the right noises :D

We should roll race one evening for laughs at Roll Racing. We'll be the 2x slowest cars there too.

I'm always in for some fun

Do not get the high volume pump - You will be just pumping oil harder into the heads and through your PCV system, and emptying your sump faster. What you want is the high PRESSURE pump. 

So yeah that's why not

I mean is it a real issue given how you use the car, no
Did you need to change the oil pump at all given that information also no

I've been told that high volume pump will be advantages in it as opposed to high pressure 

Higher volume with standard pressure for modified unopened engines

Higher pressure + higher volume for built engines, dependant on clearances

Melling recommends the 10296 pump (18% increase)with standard oil pressure for the unopened high milage and/or modified LS1 that lives under 6500 rpm

 

Melling 10295: Same volume as LS1, 10% increase in pressure over LS1 based M295 oil pump.
Melling 10296: 18% increase in volume, stock pressure over M295 and 10295 oil pump.
Moroso 22120: 18% increase in volume, stock pressure over M295 and 10295 oil pump.
Melling 10355: 33% increase in volume over the 10295.
Factory GM LSA: 33% increase in volume over the 10295.
Melling 10355HV: 53% increase in volume over the 10295.

I'm confused, isn't the flow rate at a given oil pressure determined by the engine rather than the pump fitted to it? I would guess that a high flow pump will just mean more oil pressure at idle but not necessarily more oil pressure otherwise. Assuming it was already hitting the oil pressure limit for the regulator.

A higher volume (bigger) pump will "keep" the pressure up in the low RPM's, I don't need more pressure, I just need what the stock spring gives me

LS1 engines typically have minimal pressure at idle and due to the design of the pump struggle to make and keep pressure, resulting in lower than desired oil pressure at low RPM, as I'm making full boost from the minute I hit the loud pedal more volume and a better design is required to keep the stock pressure actually there

The GM LSA has a pump that runs 43% more volume because of this, no more pressure, just more volume

The issue with the OEM pump is it also cavities at higher RPM due to its design, the Melling pump has better flow paths than OEM, which stops this happening, the higher volume also can help with the cooling and valvetrain noise at low RPM

The pressure required to meet the specs comes from the clearances, if I had a sloppy built forged engine the builder would specify what pressure was needed at the bearings, which, would then mean playing with higher pressure springs as well volume, I remember Yavus from Unigroup talking about this with my old R33 when he was playing with the regulator on the Tomei high volume oil pump getting it to the pressure the builder said it needed at the bearings. ..😟...triggered......R33.....triggered.....  😟.....oil everywhere........🤯

So, for my LS1 at least, by adding a higher volume pump, with better flow paths, the stock pressure will remain stable at idle to WOT

And for around $300, it is a cheap thing to do, seeing as though the balancer is off anyway to fix the front main

Well, thats what the voices in my head say

    • Nope.    Grab a varex and turn it down as you get close to home, win win? 
    • So, I've had my V36 for about a month now and have already copped an "excessive exhaust noise" notification from QLD TMR, reported by someone in my local area. It's a twin as per the original, and can have a bit of a throaty note to it when idling cold 😄 and if I do get up it a bit, it can be noisy, but it did pass a roadworthy inspection before sale, so.... ... but in the interest of being a good neighbour, I do want to quieten it down a bit. Is anyone here running a quiet aftermarket cat-back on their V36 or 370Z? And the big, bold question: does an aftermarket cat-back really make much of a performance difference on these cars?
    • The wiring diagram for the R33 RB25 is freely available, and is essentially the same same as most other RBs (just with differences as to which pin # does which job). To get the ECU to power up, you just need to provide power to the ECCS relay, and have the other power feeds that come in from the top left of the wiring diagram (wrt the ECU) that give perma power to the fuel pump relay, the ECU itself, etc etc, all connected. When you put power on all these it will just come to life. It's pretty clear from the diagram what needs to happen. Just follow the lines from the 12V + supply stuff in the top left over towards the ECU. I've even posted snips of such diagrams (not for vanilla 25, I think for Neo and 26) to various threads here in the last few months, talking about what it takes to get the fuel pump and FPCM up and going. Search these up and they will help get you started on doing the same with the vanilla 25 diagram. Hell, for all I know, I've done the same with that one in years past and have forgotten.
    • Yep...so unless someone posts up the answer you will need to probe from the ECU connector to the dash plug with a multi meter in continuity mode to trace the wires.  Note the ECU has multiple - and + (and across different key settings - Battery, IGN and Start) and most likely the power is fed from the connector(s) that is normally near the left hand headlight.
    • Thanks Duncan, I am actually just trying to get the Rb turning and running with the RB25DET S2 original loom itself  I am just trying to get it going outside the body and not thinking about the S15 or trying to match anything to the S15 loom at all I am only trying to see if anyone has done this and what pin they found to be the ignition trigger and ECU+/- on the dash connector, that's about it. Thanks
