Of course after the preload should have mentioned that

Thats after the167-196Nm, thats pretty important

Have a read of Mudrunner's thread. What brand of bearings were put in and which...

Could be your wheel bearings are too tight. You can Back them off a little and check for play

Edit: I think the torque settings are like 3-5nm so they don't need to be very tight

A good friend of mine converted his coil cab ute to 4.8. It was making 300-350 odd rwkw for a long time. The broke a ringland. But he drove it very very hard. After that he put about 20k into the...

Mate it shouldn't be pinging at 9psi. Do not reduce the compression unless you want a dog of an engine to drive. Is it pinging under full boost - and if so, at what RPM? Do you have a wideband - how...

As davo94 said, if you have the head off, talk to a head guy.
If you were in W.A I can point you in the right direction.
You may as well grab some head bolts and a Cometic head gasket also

Talk to any smart engine builder and get you compression chamber cc'd mod the head to lower the comp slightly and ensure the flame front is correct. Get a mls head gasket slightly thicker than...

You could fit a Cometic layered steel head gasket so it will act like a decompression plate, i had a 1.9mm thick one on my vl to lower the compression enough so it wouldn't ping but i don't know how...

big rig had the head done. I think its about 7.8:1 but he still had to take some timing out as it was still pinging. the mechanic would have prefered about 7.5:1 so some decent timing could be put...

On a petrol it is, it's already on the low side for that setup boost wise. He could get the tune looked at and make sure its nothing simple like timing. If it hasn't had the compression lowered then...

Is decompressing the way to go? To me that's just offsetting the turbo so why not just turn down turbo?
Could it be more timing or Fuel mixture?

Yeah I would be looking at custom pistons to suit.

Welcome mate. Another sa boy.. Sweet
Anyway hopefully we can sort you out so jump in and enjoy.
Cheers
