Bought a large box of oil.

(8 l engine oil) Motul 300V Competition 15W-50 Racing lubricant for racing cars

(5 l gearbox oil) Motul Gear 300 75W-90 Racing gearbox lubricant 100% Synthetic – Ester based

(6 l LSD oil) Fuchs Titan Race Gear 90 LS High Performance Limited Slip Diff Oil (formerly known as Silkolene BOA 90 LS)

(1.5 l brake and clutch fluid) Motul RBF 660 Factory Line race brake fluid

The original watercooled oilcooler, mounted on the engine block under the oilfilter, is sometimes creating a problem and has to be removed. It could be a problem with the function, available space etc. In my case the reason is a heavily tuned engine with high boost pressure. This create a very high local temperature rise. Let us call it a local thermal water explosion. This local temperature rise create a high local pressure in the cooling system and this could make the original oilcooler crack and cause a water/oil leak.

There are some ways to solve this problem, this is how I chose to do it:

Original oilcooler is hidden under the intake manifold and behind the alternator.

Original oilcooler. It is mounted on the block with 4 bolts.

Here it has been dismounted.

A close up to show how it looks behind the oilcooler. It is important to remove all trace of old gaskets and paint. The mating surface must be smooth and clean since this is the surface where the oilfilter/sandwich plate is sealing snug and tight.

In the centre you can spot the original stud. This is to be dismantled (twist it out like a screw).

In Nissan FAST software, part 15213P is found. This part is only used on engines without an original oilcooler mounted on the engine block.

img4caec8fb38a78.jpg

It is named "Stud, oil filter" and Nissans part number is 15213-V0711.

Now you can select if you would like to use only a filter, an external oilcooler, a filter relocation kit or a combination with all of them.

I use them all.

Yesterday I was informed the new R-tyres are on their way and they should be delivered to me today. The flush fit wheel air valves have also been shipped. Soon time to get it all assembled and balanced. Exciting :P

I have that kind of valve on my other wheels too and they bring a nice touch to it.

It turned out very well with the flush valves on the new wheels I use for the R-tyres. Pictures to be posted after next round in the garage. I will have to remember to always keep the air fill adatper in the car from now on.

When the tyres were mounted on to the rims, they had to pump them up to more than 4 Bar of pressure. It sounded like a big cannon in the tyre shop. My poor ears...I wasn't prepared at all... at least not when the first tyre went on.

Mounted some parts. It will be ok but as shown, there is lots to adjust regarding wheel alignment and I will also adjustthe track both front and rear. At the rear, there is plenty of Camber but still a slight gap between the tyre and the fender. At the front, there is also some space for adjustments. I will decide how much I want to slam the car when the coilovers have settled. The steering angle has improved with the spacers mounted on the inner tie rods.

It is named "Stud, oil filter" and Nissans part number according to Nissan is 15213-W040A. I have ordered one and will test it to be 100% sure it is the correct part.

The valve I will mount in the filter holder.

    • Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!
    • To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules
    • So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket
    • As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year. 
    • I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
