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

    • And finally, the front lower mount. It was doubly weird. Firstly, the lower mount is held in with a bracket that has 3 bolts (it also acts as the steering lock stop), and then a nut on the shock lower mount itself. So, remove the 3x 14mm head bolts , then the 17mm nut that holds the shock in. From there, you can't actually remove the shock from the lower mount bolt (took me a while to work that out....) Sadly I don't have a pic of the other side, but the swaybar mounts to the same bolt that holds the shock in. You need to push that swaybar mount/bolt back so the shock can be pulled out past the lower control arm.  In this pic you can see the bolt partly pushed back, but it had to go further than that to release the shock. Once the shock is out, putting the new one in is "reverse of disassembly". Put the top of the shock through at least one hole and put a nut on loosely to hold it in place. Put the lower end in place and push the swaybar mount / shock bolt back in place, then loosely attach the other 2 top nuts. Bolt the bracket back in place with the 14mm head bolts and finally put the nut onto the lower bolt. Done....you have new suspension on your v37!
    • And now to the front.  No pics of the 3 nuts holding the front struts on, they are easy to spot. Undo 2 and leave the closest one on loosely. Underneath we have to deal with the wiring again, but this time its worse because the plug is behind the guard liner. You'll have to decide how much of the guard liner to remove, I undid the lower liner's top, inside and lower clips, but didn't pull it full off the guard. Same issue undoing the plug as at the rear, you need to firmly push the release clip from below while equally firmly gripping the plug body and pulling it out of  the socket. I used my fancy electrical disconnect pliers to get in there There is also one clip for the wiring, unlike at the rear I could not get behind it so just had to lever it up and out.....not in great condition to re-use in future.
    • Onto the rear lower shock mount. It's worth starting with a decent degrease to remove 10+ years of road grime, and perhaps also spray a penetrating oil on the shock lower nut. Don't forget to include the shock wiring and plug in the clean.... Deal with the wiring first; you need to release 2 clips where the wiring goes into the bracket (use long nose pliers behind the bracket to compress the clip so you can reuse it), and the rubber mount slides out, then release the plug.  I found it very hard to unplug, from underneath you can compress the tab with a screwdriver or similar, and gently but firmly pull the plug out of the socket (regular pliers may help but don't put too much pressure on the plastic. The lower mount is straightforward, 17mm nut and you can pull the shock out. As I wasn't putting a standard shock back in, I gave the car side wiring socket a generous gob of dialectric grease to keep crap out in the future. Putting the new shock in is straightforward, feed it into at least 1 of the bolt holes at the top and reach around to put a nut on it to hold it up. Then put on the other 2 top nuts loosely and put the shock onto the lower mounting bolt (you may need to lift the hub a little if the new shock is shorter). Tighten the lower nut and 3 upper nuts and you are done. In my case the BC Racing shocks came assembled for the fronts, but the rears needed to re-use the factory strut tops. For that you need spring compressors to take the pressure off the top nut (they are compressed enough when the spring can move between the top and bottom spring seats. Then a 17mm ring spanner to undo the nut while using an 8mm open spanner to stop the shaft turning (or, if you are really lucky you might get it off with a rattle gun).
    • You will now be able to lift the parcel shelf trim enough to get to the shock cover bolts; if you need to full remove the parcel shelf trim for some reason you also remove the escutcheons around the rear seat release and you will have to unplug the high stop light wiring from the boot. Next up is removal of the bracket; 6 nuts and a bolt Good news, you've finally got to the strut top! Remove the dust cover and the 3 shock mount nuts (perhaps leave 1 on lightly for now....) Same on the other side, but easier now you've done it all before
    • OK, so a bunch of trim needs to come off to get to the rear shock top mounts. Once the seat is out of the way, the plastic trim needs to come off. Remove 2 clips at the top then slide the trim towards the centre of the car to clear the lower clip Next you need to be able to lift the parcel shelf, which means you need to remove the mid dark trim around the door, and then the upper light trim above the parcel shelf. The mid trim has a clip in the middle to remove first, then lift the lowest trim off the top of the mid trim (unclips). At the top there is a hidden clip on the inner side to release first by pulling inwards, then the main clip releases by pulling the top towards the front of the car. The door seal comes off with the trim, just put them aside. The the lighter upper trim, this is easy to break to top clips so take it carefully. There is a hidden clip towards the bottom and another in the middle to release first by pulling inwards. Once they are out, there are 3 clips along the rear windscreen side of the panel that are hard to get under. This is what the rear of the panel looks like to assist:
