I bought my first ever R33 GTR, and then shortly after a couple months of ownership, the engine started knocking, even though it was recently rebuilt by a specialist. I took the engine out, and checked to see what the problem was, and the big end bearing on rod no.2 had completely cooked itself, thankfully the crank will get away with a polish.

I have been researching into dry sump kits, and its hard to find some from the UK, most of them are all coming from USA or Australia. So I contacted a company based in the UK, who specialize in various engineering solutions and one of them is Dry sump kits. They supply kits for various engines but not for the RB26, when I asked them why is this, their reply was "because nobody has ever asked us for an RB26 kit before".

They are very aware of the oil issues on the RB26. I will be working with them to develop a near complete kit minius the lines as these will need to be tailored to each platform (R32, R33, R34 etc) I have asked them to make a kit which will be approx 98% complete, even includes the required bungs to disable the internal oiling system.

It will come with the instructions etc, and they will be using my engine block to design the system around. Their pumps start from 3 stages up to 5 stages I wanted to gather some interest from those who would want to purchase a kit and then not worry about oil issues again!

These kits will be suitable for both track and also road use, so you can enjoy the car how it was meant to be enjoyed. This will also mean we will see more skylines on track, rather than in the workshops being rebuilt.


The pricing will be worked out once they cost up the development costs etc but it will not be ridiculously priced like other kits on the market and the main thing is there will be none of that 'GTR TAX' rubbish. The prototype will be tested extensively on my R33 GTR, both on track and road, to ensure it is reliable, which it will be as the company has produced very good reliable kits for other engines.


If we can get enough interest in this then obviously there will be a discount and the price will be cheaper overall, and being a UK based company the spares will be easily available customer service will be super fast. Lets sort out the RB oiling issues properly, and not have to worry about engine failure while racing on track. Some say dry sump is overkill for the road, but I think its not and some people on here already run dry sump systems on road without any issues.

I have already contacted Mike before I posted this thread, and he is happy for it to be posted, At this stage it's interest only in this RB26 Dry Sump Kit.

EDIT: The fittings may be included, but not confirmed at this stage so all you may need is the AN hoses to fit this kit.

would it not be cheaper and easier to just extended the standard sump? which could be done sideways and the pickup dosent even have to be changed.

theres also aftermarket head drain kits to help combat oil starvation

Why do all that when you can just be done with it and fit the real solution to the problem. Extended sump etc is still very good but does not come close to a dry sump

It will be better than having to rebuild your engine due to bearing failure because the wet sump could not cope with the abuse on the track! Dry sump is the ultimate in oil control, and your engine will last a very long time.

Let's get a list going:

It is definitely the best solution to the problem, rather than just a mask.

Be good to see what you come up with.

What would you do with sump design??
Surely it would have to be manufactured on an exchange basis??

Also, on anything other than a dedicated track only car, your limited to having the tank in the boot. I found the long hose lengths caused a few problems.

Would be interesting to see how this progresses.

Ultimately interest would boil down to a few factors, being, price, quality and test results.

How would you go about placing an external pump? where would you place the oil tank?

I could be interested, but am put off as my car is primarily a road car therefore I would want Aircon (I don't think anyone does a kit retaining aircon) and I would want to make sure there is no oil smell you typically get with dry sump setups
I had a similar thought. It did occur to me that you could remove the mechanical PS pump and replace it with an electric pump and use the position to drive to new oil pump.

Just a thought.

The cause of your bearing failure is down to something else other than a pump failure. If there was not enough clearance on rod no.2 and running a bit tight not even a dry sump would help prevent that. It really annoys me when people build engines and either through negligence or lack of dedication **** things up.

I thought about a dry sump kit and it was too expensive for me as my engine was stock so would have to add costs for not only updated items but also the kit itself. If this offer of your came sooner would have been worth considering.

Good luck Saif hope it works out well for you :)

Not sure if you are re inventing the wheel here.

I know that RB Motorsport spent a great deal of time sorting out how to do this correctly and imagine a number of other UK tuners will have developed robust solutions.

They can make them from cast, but exchange would be cheaper I think.
Tank location is up to the user as you can mount it in the rear seat area or boot.

The finished sump may look a little like this:

Hopefully the cost should be affordable unlike some of the available kits on the market.

The best location fro the pump would be in place of the aircon, but some people want to retain the aircon so something may be worked out for a aircon and non aircon solution. Oil tank would be up to user

Yeah I can agree, driving a car without aircon can be a pain especially in a skyline where the cabin temps rise due to heat from engine/gearbox etc. Let's see what they can do in terms of retaining the AC.

Great idea, that could work. Also the pump could be located under the alternator or the use of a custom sump with the mountings on the sump for the pump.

hi sounds like a good idea

i understand you say

but you must have a ball park figure less than ........ 5K ? , 4K? , 3K? , 2K?

Your looking at 5k plus for a dry sump system
That's too much, I have already discussed with them the prices of other dry sump kit suppliers and they have agreed not to price them ridiculously! lets see what they decide to charge for each kit. I should know pretty soon so will keep everyone posted on the final price.

Nigel, they are going to have a meeting to discuss, how much the design, manufacturing, testing etc will cost and then come up with a final price.
