yeah i meant i would be doing all the stuffing around while on the dyno. if its all caused by detonation then there is my answer, i didnt realize detonation could wear out rings. but it is good to know that the tune is to blame. so thanx *** *********** for all the problems you have caused, apart from the oil pouring out which was caused by the rings dieing due to prolonged detonation im guessing. that same detonation sound could be heard from the second i picked up my car, thats half the reason i called them 10 minutes after i picked it up, and never got a call back.

oh well new motor and new tuner, lets hope it all goes well.

25 psi was the problem not the tune per se. Please understand this FFS. Just a few secs of det at this boost level toasted your motor not 'prolonged det'.

If you go back far enough the issue was setting up boost control on an untuned stock ecu and had moments of uncontrolled boost. Was warned not to do this.

Advised to get engine management asap and to drive the car gently until tuned but he continued to set up boost control with different actuators with an untuned Nistune. There was audible knock while doing this. On more than one occasion.

Then finally took car to EFI for tuning.

IMO the damage was done prior and EFI were left with a sick engine to start with.

i wish i knew if it had been tuned at all, if they did actually tune it, im not sure if they actually did now that i think about it but thats not for discussion at this current moment, i would assume it was tuned with the 20psi dropping to 14 psi.

im sorry i that didnt realize that even boost cut was too high for engine to run at for the split second my hit it oh wait that has been happening for 3 years with the stock turbo.

Yes, meaning it wasn't tuned for 20psi in the correct load cells. You put more load on the engine and add more boost without tuning for it then of course it's going to detonate.

I don't get your comment about the TP cut. If you increase the boost at all over factory then there is a chance it will detonate. This is why you get your AFR's checked when you do modifications like that, you don't just let it hit TP cut for 3 years thinking that means it is safe :blink:

I only ran the 18psi for a short drive, I thought it had the smaller actuator on, later confirmed that the smaller one was the second one in the box, until I took the car to the dyno I had the 7psi actuator on and wasn't revving past 3500/4000 as that's when it got to 10psi.. I swapped it about 30mins before I got to the dyno and I drove very sedately for those 20km.

And no I didn't have any audible knock as that only hit at 6000ish rpm. That all started on the way home, that's why I was concerned.

The boost cut issue wasn't something I tried to make happen, it normally made 11/12 psi. On cold mornings it would spike ocasionally without warning.

And before this gets turned against me too, yes every time it happened I turned it down a bit more.

I'm not sure, the machinist hasn't touched the block yet. I've had to put it off until I have more cash. Christmas has emptied my pockets. But with any luck I should have it back on the road and fully tuned for my birthday in march. If I decide to keep it. I'm wondering if someone would be interested in buying it before i even turn the key. :/

    • Got the motor out and torn down. I'll be dropping off the block Monday. Luckily the scoring on Cyl6 is much less pronounced then the pictures made it out to seem. It can barely be felt. If you pass your finger over it 10x you'll barely notice it. Hopefully by some chance it will only require a honing. I'm not in the mood to buy one size larger pistons or another block. Oddly enough my 6th cylinder with the scoring has extremely clean intake valves compared to my other 5 cylinders. I'm worried the scoring was caused by too much fuel or Water/Methanol washing the cylinder. I'll review some old logs to confirm.  This was also the first time I pull an engine with the transmission still attached. It went much better then expected. I was worried my CD009 wouldn't make it easy due to its sheer size but it was much easier this way. 
    • From the pictures I have when doing the job the flywheel is the same diameter, I don't think they're playing weird tricks like putting weights at the outer diameter to increase flywheel inertia or anything like that. The OEM flywheel is definitely heavier, but it's not a huge difference. Quoted weight savings of the clutch is 2 kg so I can't imagine the flywheel being lighter than ~7 kg. Kind of regret not weighing it before the clutch went into the car but as far as driveability goes I have no complaints.
    • HKS trigger kit should be very easy to integrate with a Link. It's a 36-2 crank trigger. Hard part is finding the motivation to take off the timing belt and everything on the front of the engine to install it. You also need to cut out a hole in the oil pump housing so the sensor can read the trigger wheel. Changing out the cam sensor for a 24 tooth setup is probably good enough but as others have mentioned depending on what underlying assumptions are changed it becomes more of a problem. Reading the crank state off of the cam is an abstraction that works in the general case, but if you have an edge case it makes less and less sense. There is a GTX2860 gen 2 that can take a compact 5 bolt housing so it's direct bolt on but I'm not 100% sure of what's involved. Peak compressor efficiency drops off a bit on these turbos vs -5s, 77% vs 73% but you get way, way wider region of operation. The -5s have a really strange surge line in their compressor map that is all over the place. If you think the hot side on the -5s aren't open enough you can try the Tomei T550B turbos which a local tuner seems to be happy with:
    • i need a complete tail light for my R33 GTR if you have please let me know.
    • I need a great maintenance workshop around Idaho, if you know one please let me know..
