No Idea but I hope not. Hopefully they have it perfect now !

(I have one)

Do you mean this ??

NITTO utilizes their precision CNC machined cast alloy outer housing and along with their already proven oil pump design NITTO has now released a new billet alloy backing plate allowing further stability to oil pressure and flow at high rpm levels by minimizing any possible flexing of the housing.

This was the email that was forwarded to me. What I had been told was that the housing and backing plate materials were changing.

Housings being finished off this week and assembly will start again next week. I have about 40 back orders to fill but will advise as we are getting through them. Not long now.

Tomei pumps still fail unfortunately.

I just got off the phone with Nitto. Guy I spoke too was super helpful.

They are still testing these new spline drive pumps. They rekon they are pretty happy with it now. But until they are 100% they wont release it, understandable...

No definite date for release, but a ball park was a few months.

Hi Guys. Still working on the spline drive for our pumps. Was hoping to have this finished well before now but we have made several spline contour, clearance and count changes during testing and development. The field testing for this product is a nightmare also with the main test vehicle being a high HP GTR with 2 step etc and each time we change design the engine needs to be removed to allow for pump removal then installed again, then testing, then more testing, then engine / pump removal for inspection, change to new inner gear, remove collar and install new collar and so on. You get the idea. Hoping we have a final revision for testing now but I would be lieing if I gave you a finish date.

As far as the housings go we have just finished casting a new housing that is very similar to the old one but is a new mould, new casting technique, new material, logo and some very slight gallery revisions. Only reason this was done was because we were having some supply issues with our current casting plant which does not fit well with our stocking promises. Pictures on our facebook page (Search Nitto Performance Engineering).

Hope this sheds some light and while I'm here what's with the hate R31Nismoid??? Bit arrogant yes??? As stated many times before our pump is very different to the JUN / Greddy pump made by the same factory. Do we need to go over this again?

Thanks for sheding some light on the spline drive Andrew. I'm happy it's taking a while... means there is less chance of failure for my engine- I've been an advocate for a spline drive rb oil pump for years now and I'm glad an Aussie company is developing and testing one.

Don't worry about Nismoid... he dosn't hate you... he just hates everything :verymad: mr cranky pants. :woot: :woot: :woot:

As a side note, maybe have a look at registering as a trader on SAU (similar to Risking). Obviously it's a great way to reach a large part of your target market for this pump.

      S15 Spec R

      A few small updates since the previous post and lessons. I decided to do a little interior light upgrade on the 110. I quite like the iilumo items, even if they're a bit of a premium over other brands. You'll also note the Stedi Fogs, that will go into the S15 fog lights as I needed to match the bulbs since I got the new ones earlier. I hope they fit as the body is quite a bit longer than your normal bulb.  Annoyingly, I managed to trip the fuse, which normally wouldn't be an issue until I located the fuse. I can't say I've ever come across this. I had lucked out that someone nearby had a spare, but oddly enough Toyota dealerships seem to keep this in stock. I ordered some to keep in my stash and as luck would have it, someone else nearby tripped the same fuse so I passed on the favour.  I also did a little service on the 110 ahead of some additional work coming up. It's been annoying that Goleby's stopped carrying this particular HKS filter for the 110, so now I need to keep them on order from Japan. I also took the opportunity to install a bash plate and number plate riser. The plate riser is such a cheap but nice fix to help really tidy up the car. I'm tempted to now also replace my headlights, on this car. Both items were from Project Aero.    I also needed to replace the rear tyres on the 110, and after trying to get it aligned learnt that I need to replace some bushes in the front end, so that's next.  Closing out this update with a nicer picture as always!

      R33 Fuel Pump & Brakes after alarm swap

      Appreciate the correction on the "ground", that will make a huge difference to looking at this. That makes complete sense about AF70/AF71 which is what I had come down to being the issue, one of these. I'll have another look in the ignition wiring when I get a chance next week. I'll also make up a jumper wire for running that AF73 test.  ECU is fine, relay itself is fine, pump harness is fine and the pump itself is fine. I am going to upgrade the Walbro 255 anyway with a DW300 I have since I need to replace the fuel sender and I'm going to upgrade the FPR with my chasebays kit ready for new plenum/injectors/dbw, but I'll get this working first. That's why this is so frustrating.
