Given that current exchange rates have pushed the price of tomei oil pumps un near the 2k mark - I was wondering if there is any other options to upgrading the oil pump on my RB26. I have heard some talk of a CNC'd Pump Gear assembley that is larger and manufactured from better material than the stock and N1 oil pumps(??). The other thing is I assume there is more than just the gear assembley to upgrage... e.g can a stock or N1 housing be machined to accept the larger gear and so on....

I think it is a great idea if it is possible for the pump housing to suit the strengthened (possibly larger) gears. Buy a new N1 pump (or possibly standard) and replace the gears with some CNC machined ones out of some very tough alloy would be a viable option. Also, because the pump does not have an increased flow rate (like the Jun and Tomei ones) you may not have to worry so much about increasing the capacity of your sump (less $$$).

Not sure how everything fits into the pump but you would want to have an idea on the tolerances for the gears other wise you will end up that famous creek without a paddle.

Oil pump gears to suit RB pumps are not too far away....being manufactured as i type this

You are a good one for keeping secrets Paul, and releasing bits of information, haha.

- What material?

- Where did you get the design from?

- How do you know what tolerance to machine to?

I am sure there are more... that should keep everyone going.

Uh huh........

Actually they quoted me $550, just had a look at the email I had a while back.

From an email I recieved from power tune:

Yes, they are modelled on the N1 gear set so are exactly the same size.

The difference between our gear set is the material they are made from which is a pre-hardened alloy composite and as such does not require heat treatment.

As a performance part, we regret that we cannot offer warranty. We developed these gear sets out of necessity as many of our customers had broken so many of the N1 gear sets.

We made our first set in 2006. It was put into a 400kw GTR and is going strong.

if theres genuine demand i could push production of mine?

A complete new Pump incuding housing ?

Or just a new set of 77mm N1 Pump Gears ?

The best thing about this idea is the option of Gear upgrades for those that bought N1 pumps and don't want to get rid of them, but are scared to use them without the upgraded gears.

I am not sure if a redesigned pump would sit with enough confidence with most people.

if you want to upgrade your pump gears but the reimax ones. they are the best. they make the gears for group A race cars etc. formerly reinik.

up till a few weeks ago they were about $550 too, bit more now with the bad exchange rate though. but they are good stuff. I know a few people who have used them in pumps both here and in japan with good results.

    • Per Mark Roberts of Sonictune: Mark Robert Author At this time, no. No ETA either 2016-17 models. You will be able to purchase and install a 2018.5+ TCU though   TCU purchasing and pricing info! As we near the release of TCU tuning, I am going to answer some questions I get asked often.   What do I need for TCU tuning? At this time, you will need a 2018.5+ TCU to be able to tune. If you have a 2016-to early 2018, you will need to replace your TCU with the newer version. One good way to know if your TCU is good is if you have auto upshift in manual mode in 1st gear around 6500 rpms. If your manual 1st gear goes to 7k rpm and will hit the rev limiter unless you shift, you have the older TCU.   Why do I need to buy another ecu license/phone flash if I already have it on my ECU tune? The TCU is its own computer module. It is completely separate from the ECU. Because of this, you will be required to purchase a TCU license and, if your tuner has it, the phone flash license required to tune it via phone/bluetooth.   Do I need TCU tuning? TCU tuning is NOT required. However, the faster your setup, the more it will assist in track and dragy time consistency.   If I’m ECU tuned by (tuner A) can I get my TCU tuned by (Tuner ? Yes, since it’s a different module and a completely separate flash, you can have two different tuners. However, it is highly recommend that you have both tuned by the same tuner. For me, my TCU tuning will directly complement my ECU tuning style and features and running my ECU and another TCU or vice versa MIGHT cause some issues. At this time and for the foreseeable future, I will only be tuning my current ECU tuned customers TCUs.     I have a SYVECS AWD controller. Do I still need it? Yes! The AWD controllers main job is to control your AWD system. However, with TCU tuning, you will no longer need the auto-shift function as that will be done through the TCU. The AWD controller will still be very beneficial for racers looking to maximize traction on the launch.     Shift schedule changes: holding gears longer at lower pedal input as well as max shift rpm changes. Please note, the new ECU race rom coming out will address 90% of the shitty drivability issues these cars have through custom maps from myself and Racebox—as well as others I am sure.   Increase shift speeds: as seen in the videos I’ve been posting, the TCU shifts much faster once tuned.   Increased shift pressures: as also seen in the videos, much firmer full throttle shifts.

    • The fancy pants red shock tower brace is finally incoming from MX5 Mania, getting it shipped from 'Merica has been a long and problematic process, and GWR, the 'Merican supplier will not ship directly to consumers outside of the US, Mania basically had to order a heap of them, the colour choice was silver, or red, and we all know anything red adds 5 killerwasps of dynotorques..... Whilst it does fit over a 2.5, and I've seen a few photos and videos of it being installed and fitting, google also says it might get real close to the FAB9 intake front runner, people in the US says it does fit with the FAB9 intake, except for one person who said it slightly touched.......so there is that.....LOL..... As it seems that I am the first in AU to have this combination of parts there's no local knowledge about fitment, so I'm just a willing guinea pig in this endeavour, I'll cross my fingers and toes and hope for the best In other news, I ordered stuff from China  on the same day I ordered the 23° silicone bend from Victoria, the stuff from China arrived a day ago, the 23° silicone bend is still travelling around Australia thanks to Australia Post, and "may" be here next week
    • Very good news...I contacted Racebox about it last night. My car is a 2016 so remains to be seen if it is compatible, requires a TCU swap, or is impossible.
    • What ECU are you running? This is probably the biggest question. If it's a PowerFC, I'd probably change the ECU and get something newer that will handle the injectors in a nicer way.
