Pro Engines CNC Machined Nissan RB20/25/26/30 Oil Pump Drive Collar

Our Nissan RB Oil Pump Drive Collars (also known as Crank Collars) are precision CNC machined from Chrome Moly barstock. Our collar replaces the narrow oil pump drive originally machined on earlier Nissan R32 RB26DETT crankshafts, as well as all RB20DET, RB25DET, RB30E and RB30ET crankshafts. It can also be used to replace a worn oil pump drive on R32, R33 and R34 RB26DETT crankshafts. Our collar provides full engagement on the inner oil pump gear which greatly reduces the likelihood of oil pump gear breakage in these engines.

Each collar is supplied with detailed instructions and fasteners. Machining is required to fit this collar and therefore it can not be fitted to a crankshaft while still fitted to an engine. We can supply and fit the collar to your crankshaft for AU$350, or AU$550 to chemically clean your crankshaft, supply and fit the collar, check journal sizes, micropolish the crankshaft journals and fit screw in oil gallery plugs.

We have collars in stock ready to ship.

AU$150 each or AU$125 in multiples of 5 or more

this is pro engines.. probably be worth sending your crank and pump over to him! have dealt with him in the past and he is tops... very clued up on 26's

why not collar it?

only requires, machining down and interferance fit/grubscrew

I had a collar but sold it as I've decided to go a different way. I want the snout welded up and machined back to suit my oil pump gears with my specified clearance.

What exactly is the question ? Do you want to know if anyone has used Performance Unlimited ? There are plenty of performance workshops around who could provide similar advice.

Have you read the thread on Oil Control ? Do you have oil restrictors etc ?

Hmmm, I hope this isn't too off topic, but I'm curious about something.

I saw you mentioned in a post a while ago about changing out your lifters and valve springs to push your red line up to ~9000rpm. Where did you get work like this done? I'm quite keen to do this myself as I've swapped out my turbo recently to a 3076, and while lag for these isn't meant to be too bad, it is, at the end of the day a reasonably sized high mount turbo, and I fear that soon I will be lamenting my lack of reponse. How do you rate the change, would you do it again? Is it a good idea?

I saw in the same post you mentioned that you thought most engines would become innefficient at that point, and I'm with you on that, but at which point would you say it becomes unfeasible to rev an rb engine?

Apologies for the essay, but curiosity really has gotten the better of me. And plus I've remembered my password for the first time in weeks and been able to login on something other than my (currently dead) main pc.

Cheers,

Tim

EDIT: Feel free to PM me on the subject to stop this getting even further off topic.

Take it somewhere where they actually want to work on it? :laugh:

another really good work shop is top racing in carlisle they built my rb30/25 engine its making 550hp at wheels and well over 600 with the shot of nos they listen to what you want and help get it done right the first time

    • @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.
