Dear people,

I have conducted a search and found no info, so i need your oppinion.

I am currently building a meduim to high hp rb 30 /26.

I have assembled the bottom end and all good gear has been used .

BUT dam it i did not get the crank oil pump collar widend.

No one over here in WA does it any way.

I have just been informed that this was a crucial mistake and my N1 on the standard crank will not last 5 minutes , i tend to disagree.

Is it mainly in tired r32 rb26 engines that they let go ?

If this is the case what if i replace every , say x amount of km's.

Will this help or is it simply an hp issue.

Sometimes i wonder if some things i get told from tune shops are simply a "turnover factor " . Please enlighten me on this if you would not mind , are there any alternative measures i can take . some one mention a collar that can be bought or made .

Thanx

i brought a JUN crank collar about 200 bucks from greenline but i think these are grub screwed in so may be hard to fit if engine is together.That was for an R26 crank not sure about the R30 cranks

    • The final part arrived today to un-clampify and simplify the intake Who would have though a 1/2" hose stainless bulkhead fitting designed for below waterline bilge pumps would be what I needed Test fit on a 3" offcut I had laying around to see if it would work, and it worked a treat All going well the intake will be on its "final version" tomorrow 
    • Good luck on the weekend mate
    • Must have been an absolute nightmare to drive when the power steer was out, the rack ratio/wheel size/caster is all set up for power assistance
    • Welcome to SAU, what are you looking at buying?
    • I checked the injectors again (1 and 2, since they’re easiest to access) to make sure they weren’t clogged. Even though the entire fuel system had been cleaned, I wanted to be certain. Everything looked clean, so I reinstalled and connected everything. When I started the car to confirm everything was okay, it immediately revved up high, so I shut it off straight away. I checked to see if I’d missed a vacuum hose or something, but everything was connected. On the second attempt, the car ran without the high idle, but I noticed a distinct “compressed air” sound coming from the engine bay. Tracing the sound, I pushed injector #6 forward slightly and the noise stopped — it turned out it wasn’t seated properly, despite the fuel rail being bolted down. While holding it in place, the car idled steadily without stalling and ran for over 5 minutes. At this point, I pulled all six injectors out just in case I hadn’t seated them correctly or dirt had gotten onto the O-rings. Unfortunately, I discovered that I had damaged 3 out of 6 injectors (the OEM 270cc ones) during installation. So yes, this was my fault. Since only the pintle caps were damaged, I’ve ordered a Fuel Injector Service Kit from NZEFI to refurbish them. In the meantime, I reinstalled my new injectors – the car now idles fine for over 15 minutes without stalling. I have not attempted to drive it so far. It’s not perfect yet, as it hesitates when the throttle is pressed, but it’s a big improvement. Unplugging the IACV with the new injectors idles at around 800rpm, even with the IACV screw tightened fully. But this is probably due to tune.
