weekend car only - i managed to get 5000km out of it but i was prepared to rebuild which is why i didnt really care.

ring land collapsed - started breathing heavy & lost comp in no.6 cylinder (usually 5 or 6 will let go 1st as they carry most of the heat)

Fair enough, my point would be lots of factors other that outright power could be the blame for the rings collapsing. A lot of those risks are reduced when using ethanol based fuels :)

I'm not going to rebuild but happy to drop another stock donk in the hole!

What caused the failure?

It's probably only a matter of time but I don't drive it a lot and only use 1.3bar most of the time, which makes 350rwkw with correction off or 373rwkw with correction on

too much boost for stock internals - with forged internals this wouldn't happen

If you get 6-12 months out of the motor it is probably cheaper to just keep throwing second hand bottom ends at it than to build one.

Would you consider over 150 power runs on a stock CA18DE+T with 56psi boost too much for stock internals?

Engine was still ok afterwards too.

I think Sean at EFI was running 610rwhpon his RB26 with stock internals for ages. That was on gas though. Still didn't break a piston though. It has a lot to do with the quality of the tune/tuner

well ive popped 2 bottom ends to date, tuner is highly reputable (crd).

i wish i could get away with a factory bottom end - im sure many others on here do as well :(

if you want to push it hard, it is only a matter of time

mate i thought you were joking when you said you were putiing it on a hub to see how much power it could make.

not a bad result still fell short of the 3076 though hahaha :whistling:

Why would I joke, I nearly got convinced to do a run with 1.9bar and 8500rpm but managed to contain myself!

By 0.4kw haha

I'd rather have my power curve than yours :)

we should get the 2 graphs over-layed easy to do since they are making the same power.

but

3000rpm yours 60kw mine 95kw

3500rpm yours 85kw mine 140kw

4000rpm yours 130kw mine 240kw

5000rpm yours 310kw mine 410kw

i know what i would rather :whistling:

There you go :)

Yours has a much smaller power band compared to mine, it does come on a lot harder though!

Am i reading that correctly? You made over 400rwkw with a 3076????

Did you draw the dyno graph yourself? :)

2.2bar and E85 I believe

yeah I am confused, unless you somehow run 30psi with ridiculous temps and meth or something? though would have thought the compressor would be way out of flow by then

As above, boost apparently went to 32psi but the compressor ran out of legs and power dropped a lot top end

I was there that day and the most i saw it spike to was 28 and holding 26psi...I know which turbo i would rather in that comparison, the Kando seems to be a good cheap option but it definately isn't a competitor to Garrett imo (nor should it be i guess for the money). The above plot proves that. BTW who in their right mind would rev their stock 25 to 8000rpm just for a number. Crazy....

yeah it definatley was 32psi at peak power dropped off to 27psi.

Definately thought it was 28 lol....Cold mornings/evenings will be interesting. Time for a swirl pot and another 044 me thinks.

I'll print off a overlay of a GT3076R vs Kando T67 with very similar mods and on the same dyno... You will be very surprised how similar they are :)

If I wanted to I can do a 13-15sec ramped run and make my graph come on that early like "wasnt me" run.

I'm not revving it to 8000rpm for a number, it's going to be like that all the time... If I wanted a number it would be going to 9000rpm

Not really crazy, most the drift guys over here run 8500rpm and sit on limiter all day without too many issues

    • 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.
