fuel cut explains the massive flames that gtr's shoot out on the limiter - most gtr's u will see in japan run this way. so my guess is that fuel cut is acceptable but not sure if its better or worse t

errr....might want to re-read what you just wrote Marko. No fuel = no flames

same shit for an oil pump, engine is still stopping and starting in the same way. the only difference would be between different ecu's, for example, a stocker rb30e ecu cuts fuel to all cylinders when

toyota pump drive is awesome its a dam shame nissan didnt steal it off them, i mean just look at all the oil pumps for a RB26 how many to you hear being put on to 2J's etc !

Probably about the same amount of 2j oil pumps put on rb26's.

That may be my next step. Your totally right on tho!

What happened to the guy that was designing the splined gears? Machine work in Canada is relatively cheap. I got a few guys I use and its very reasonable. I'd like to see what this other guy ended up with as a design. Did he make new gears completely or just the inner gear and drive for the crank?

I think there has to be a cheap solution for everyone. Or we could all go dry and call it a day. none of this inbetween stuff ($1500 for same design pump)

Inner and outer gear to suit an N1 pump housing and a splined crank collar to suit. I was going to trial a set but he got jerked around by his machinist who then went out of business and the guy lost several thousand dollars on the venture.

Woah, that sounds ridicules. poor guy! I think I remember hearing about that on these forums a year or so ago. I dont visit too often, but the Canadian forums are boring to read these days so I wanted to read over some of the good threads here.

Tho, not sure how he can loose several thousand dollars??? Unless he was in a production run of them. Cant see loosing that much on making one or two sets and then trying them out to make sure they work. Do you know if he started with one gear set and get a chance to test the design?

Im not even sure I'll get around to it. i think after doing all the stuff to help out the RB like collars, restrictors, drains, vents, sumps ect Its more less go dry set up now. Id only do these gears if I could get them for less than $400-$550 CAD for the new gears and drive once you get into production. Sounds like a great idea tho.

To tool up for one or two sets was too cost prohibitive, he had forked out for materials and tooling for a run of 10 or so I think. I was going to be trialling a set before he put them up for sale.

RB30 Ceffy.. any chance you could see one of your machinist contacts over there with a set of N1 pump gears & stock set of 2JZ gears to make this happen ?..

Or get an idea on pricing for a small run of them with EN series steel.

yeah, Im looking into it. Bit busy with some things but that was my next step. Wasnt sure if its really worth an entire set of gears for the price you can get an aftermarket pump for. But once I have an idea I can post what I come up with in here. I've had the idea of using something like the REIMAX gear set with a 2J style drive. Had another member on here just PM me on the same subject. Im just not sure when i'll get around to it. My friend is a CNC drafter and I have several friends who run the machine. I just dont have any capital at the moment to buy the gears for a copy and i am no engineer to configure a new pump on my own. If anyone has a draft made up that would work or could have the drive modified i would be more than happy to help set things up.

      Is it alright to top up with just another green coolant?

      thanks GTSboy. My confusion at the moment is i am trying to locate the ignition, ECU battery power and the ECU negative The closest thing i can find is the for the S15 on Page 8 of the Wiring Specialties web page https://drive.google.com/file/d/0B9F33_M_GgENQnZ6STMxVmVNd1E/view?resourcekey=0-eZ4nNRwRoqa1qvKlWWHm8A I cannot find the same diagram for the R33 RB25DET Series 2 dash plug pin out.... Do you know what the Pins? or know where i can find the same pinout diagram for the RB dash plug? Thanks for the advice on the box... i like a 6 speed so might be on the lookout or the box now.. a topic of discussion for another post...

      Put another overflow bottle (ie, a 1.25 coke bottle or similar) under the overflow hose and see if it is being pushed out there or if it is disappearing into the engine.

      Staring on a stand is no issue. You just have to wire everything up, give it fuel and cross your fingers that the stand is robust enough. Arranging the inlet plumbing is often the hardest part, without any surrounding structure to hand some of it from. No need for coolant if you only want to run it for <1 minute. As to the gearbox - I think the little Aisin box is a bit stronger than the other small Nissan boxes that went behind SRs, but I wouldn't be too keen to test its limits with the torque of a boosted 25. I don't know if you can retain the box and the tailshaft. The box won't connect to the RB without an adapter of some sort, which is either a plate that will push the engine forward (which is not good for fitting it into the bay's available space) or push the box back, which messes with the box position and tailshaft length - OR - cut and shut work on the bellhousing, which is a long way from "least modification". I'd be buying a new 370Z 6 speed or similar, doing what has to be done to that to make it fit RB (ie, cut and shut bellhousing) and the requisite tailshaft custom/mods.
