Took the s13 out on the weekend, it's running a 285rwkw rb26dett, and I'm finding that engine oil temp is getting upwards of 120 to 130 degrees when I really start pushing the limits. It does have a reasonable size cooler. And at the moment i have ulx 110 in there. I'm curious to know what everyone else's temps are, It just seems a little too hot. The front bar will be coming off anyway as the next meet Won't be till late January, and I'm looking at running a whole heap of air flutes/ducting anywhere I can fit it.

Off topic here but why is it that when I type G.O.D. As one word it comes out as rajab?

I'm still a tiny bit sceptical but I guess if it's a per oil change per track day it should be good right?

I saw 140+ in mine after a few laps in summer, that was with a 30 row expensive cooler, running a 14 inch thermo fan. A good synthetic will take it though.

That said, we had to tape up all the coolers on the the Gibson GTR the other day at Sandown as nothing was getting up to temp after 8 laps.

good grade 4 syn will take it, just don't use some magnetec shit and expect it to last :)

I would try to keep it under 130 though, at 140 it starts to really thin out and start to break down

So is GW Synx3000 but it's quite good if you drop it regularly. Full synthetics like the heat more though, and will last longer, but who cares if you drop it every track day...

Only reason I am running Penrite racing 10w40 now is after speaking to the penrite rep, he showed me oil analysis results between the various oils in their range, from actual race meets, and the racing synthetic is perfect for high track temps, the film strength remains for much longer in track conditions. High Zinc levels, SN rated for e85, and It's a reasonably priced oil too.

So does that make the oil better? I would have thought the oil which is hotter is doing a better job of removing heat from the piston crown, which is a good thing.

I agree though, if you are dropping your oil every 300k's it wouldn't really matter what quality oil you run, other than Magnatech? Are you kidding me? It has the worst name ever for sludge creation doesn't it? So many people have warned me away... I would be too scared to try it.

I just buy magnetec for my shitter Accord V6 and drop it every 5000 km as it's $22 LOL

For the fridge I just run Mobil 1 ESP 10W40 and it seems to be good for street & track, don't really have any heating issues as car still makes pretty homo power figures

Pete dumps the oil after every track day, so I don't think the oil has time to break down and sludge. Helps when you have a trailer so you don't have to worry about driving it home :P.

At the last track day, using Penrite Racing 10W-40, I was regularly hitting 130°C lol. Car still drove home fine, dumped the oil after as I didn't want to risk it. Oil was about 3,000 km when I hit the track lol.

When i put the oil cooler on my 32, 1st track day the temps went to 130+ so went home pulled it apart and freed the thermosate and put it all back together and I haven't seen it go past 110 on the track since, 16 row no fan, if I saw 140 with a cooler that big I'd be looking long and hard at it, then tell someone to fix it !

I used to run Nulon 15-50w street/track, I now use Brad Penn 15 or 20-50w, the green oil

      I have more than enough digging, laying blocks, moving gravel, airrating, feeding and top soiling the grass, and setting up the veggie gardens growing some seedlings,  and then removing all the unused rock to keep me busy for the next few months at least,  hopefully the rain stops soon so I can get a few hours in this arvo, but, before that Sunday is washing day, is every body happy, you bet your life we are Nice country road day drives are a day off whenever I'm muscle sore from all the landscaping at the moment, but, more epic multiple day drives will start once the majority of the big jobs outside are completed

      Recommendation for engine oil funnel spill free

      By MBS206 · Posted

      I thought I'd come back and add something I JUST learned. A Toyota LandCruiser with a 1HZ, mates perfectly with a bottle of Nulon brake fluid. As in, it perfectly screws in. Great make shift funnel when you cut the bottom of it off. This may work for your Corolla.   Unfortunately, tipping a 10L drum is much harder than a 4 to 6L bottle, and they no longer include the easy pour tap which was just perfection to use previously.

      Fuel Pump Control Module & Dropping Resistor

      By EndZee · Posted

      Guys since i bought r33 gts25t coupe 1994 automatic a/t(manual swap 350z gearbox)  all i got is problems, always problems. Lets start with that when i turn key into ignition(ON) fuel pump doesnt always works. Sometimes i have to turn key twice Off/on/off/on until it primes. Its new, dw300 - 340lph. My gearbox broke so i did gearbox swap, install different intake manifold, injectors and i take pipes. Car was sitting in garage for more than half a year. I did assembly all not that long ago and when i turn ignition cant hear prime. All of sudden it stopped working. Theres many videos on YouTube how to make relay mod on r33 straight from battery so i did and it doesnt work! 😰 30 - battery positive  87 - positive from fuel pump to relay 85, 86 - one of two wires from original fuel pump wires(light blue, grey) and it didn’t work. so I check on ignition and took original BLUE relays wires from trunk, next to fuses. (I believe it’s IGN+ and ECU pin 18. it didn’t work…  tried connecting (IGN+ from og relay) and (ECU 104 from 1of4 FPCM wires) to my new relay 85/86 and it didn’t work.  I unplug FPCM. Didn’t work. im thinking what’s wrong   fuel pump is working, if I leave IGN+ on 85 and 86 straight to ground it works but it’s just nonstop. Since it getting constant 12v after key in ON. light blue wire gives me 6-8v.  so how this should be connected? What causing ECU not giving — on pin? Or I did sth wrong and that’s why it doesn’t work? I need negative signal on ECU that control fuel pump. What this should be?
