na just a good gated sump from asr. i'm not overly thrilled about the extra weight from the extra 2l of oil, so the idea of all the extra weight for 12l of oil and the lines and shit for a dry sump don't make it a good sell..... and i'm being a giant jew.

Funds is the only thing that is stopping it from going again. I've got the new bottom end there ready to go, just need a bash some restrictors in it, and buy a sump.

na, still hydro lifters. Only reason I can see a need for solid lifters would be for bigger cams. But I can't see why you'd ever put bigger cams on a 20, as they came over cammed from the factory.

boost and revs=full catch can. There is a guy down here who circuit races a std RB20, and he won't rev past 6500 with the same boost as me (23psi) because he fills the catch can. The amount of oil that is coming out can't be fixed with catch tank tricks. And for the $30-$40 it's going to cost I thought I might as do it. I'm using SydneyKids specs.

had 263rwkw at the start of the week, 200 - 220rwkw on the new engine (depending on the heat of the engine), then take 5psi of boost off from day 4 onwoods...180kwrw??

E85 did give it a good kick in the pants though. I only tuned the 98ron map on the road, so I don't have a power figure for it.

I was running 24psi and 8000rpm out of my RB20 for a fair while running about the same power as you...

Not a single drop in my catch can and that car got belted the f**k out of it on a stock motor, so maybe the motor is a little loose or tired?

I'm at a bit of a loss to be honest.

I'm struggling to understand how .2 bar can make such a difference. Mine doesn't pump into the catch can either, and I'm not exactly easy on it. Even after 5 days of targa there was still no sign that there'd been oil in the can at any time (I have it so it self recovers if it does pump into the can)...... Hell, #1 piston was half melted away and it still wasn't pumping oil! lol

I'm putting mine back together stock internally, and will be interested to see if a little more boost tips it over the edge.

what thickness oil do you run? I was using Motul 8100 5w-40, but i'm going to goto 25w60. Neither engine was compression tested or leak down tested.

The N1 never has this issue, even with 25psi and a big nitto pump.

Yeh Castrol for all RB20 crate motors :) I have only ever blown oil when there was plenty of limiter action. Bump the limiter a few rpm so i never hit it and no problem. Even the breathing on limiter isnt a common thing, but its about as good as i can do for a reason for the 2-3 times it has happened

    • 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.
