Gb#2: Jun Spec Crank Collar & Oil Restrictors (x2)


Recommended Posts

Hey all,

I just got off the phone with Matt @ the GTR Shop in New Zealand. I purchased a crank collar and 2 oil restrictors (package deal) for a total of $130AUD delivered.

He told me that the collars are made to JUN specifications and are sought after in bulk from many people in the US with RB engines (10-20 sets a week). Oil restrictors are the same as the ones you would get from Tomei (1.1; 1.2; 1.5mm available)

Matt asked me to put this up as it's easier for him to get something done in bulk than to make 50 trips to the post office...

1-5 sets: $130AUD delivered

5-10 sets: $120AUD delivered

10-15 sets: $110AUD delivered

By "set" - 1 x crank collar; 2 x oil restrictors (any combination)

Straight from Matt:

We supply grubs screws as a fail safe, but if correct fitting is acheived are not needed other than piece of mind, screws are 5mm

Also interested, this is what I need to run an rb26 pump on an rb30 bottom end right?

Nope, it's for using a wide flange drive oil pump on a narrow flange crank eg; R32GTR N1 oil pump on an RB20/25/30 or early RB26 crank.

:( cheers :)

:P cheers :happy:

Isn't that what I am trying to do? trying to put an 33gtr oil pump (wide flange) on a Rb30 crank (narrow flange)?

Ok so that's 4 sets... need one more :kiss:

BTW I'm still waiting for the one I ordered so shipping from NZ has taken a little bit long.

so is this an actual jun collar or knock off.

ill be buying one of these very soon, once someone can confirm this i could be interested if they arrive soon.

(organiser pm me pls as i wont check here often)

thanx

Humz; Matt from the GTR Shop has advised that this is a JUN spec knock-off - the materials and dimensions are exactly the same (what I've been told anyway)

I'm STILL yet to receive mine but will post up photos as soon as I do.

Just received the following in the mail:

1 x Crank Collar

1 x Grub Screw (black)

1 x 1.50mm Restrictor

1 x 1.25mm Restrictor

I'm not an engine parts expert but they look to be in good form; the machining is pretty good (no rough edges; no barbs etc etc.)

I'll take some photos tonight and post them up :D

Oh BTW; the reason why there is a 1.5 and a 1.25mm restrictor in there is because it comes with 2 and I didn't know what I needed / wanted so I just took the two most common ones :D

    • Does it also misfire equally when revving?   Josh is very correct in what you should do. The coilpack harness wiring loom itself is a known problem due to its age and the number of heat cycles it has gone through. Throwing parts at a vehicle to diagnose the issue isn't a smart or good way to do it. Secondly, you may have a bad coil pack, you pop replacements in, they fix that issue, but messing with the harness breaks it, so the issue persists. So now you think "well it wasn't the coil packs" and have to continue chasing your tail, potentially swapping back in your shit coil packs and returning the good ones (yes, I've seen people do this because 'it wasn't the problem' and they want to save money). And suddenly, you've got two issues with the same symptoms...   Diagnose, don't use the spare parts shotgun.

    • Wanna rewrite all of that in, say, 2 or 3 separate sentences, so that we can read it?
