NEVER LET THE CAR IDLE!

Start the engine and vary revs from 2-2500rpm as Sean suggested. Get someone to check for leaks of any kind while you do this or check your self while someone else does the revs. Just go up and down up and down. Do that for about 10 minutes until you are satisfied that it will drive safely. Make sure the car doesn't blow any black smoke and the oil pressure is good before you go. When you start it, it should have between 80-110psi cold and once warm expect between 30-40psi. Monitor the oil gauge at all times. Go for a drive and load it up on hills ie. 5th gear at 1500-2000rpm and try to climb the hill. On the downhills, put it in 3rd an decel. Get the engine to work on the downslope as the vacuum it creates will pull the rings against the bore. When you come to a stop at lights, free rev in neutral every 30 seconds or so, just blip the throttle to avoid long periods of idle.

You will need to drive like this for at least the first 250kms

Oops, didn't read the rebuilt engine bit lol. Yeah load it up to bed in the rings, hills are good... I went as far as disconnecting the wastegate actuators from the arms so I had no boost.

      I don't think the shuffle can damage the turbos. It only happens at low shaft speeds and loads. It's just annoying (to some people - others are tickled by the effect) and it quite possibly reduces spool performance a little bit.

      Oh dear. The panel beating needs to be done before the filler work. Do you have a photo of the dent before you started? Hard enough to not flex and only hit the high spots?  What do you mean it was just temporary?

      I appreciate the detailed explanation, think I understand now. I spent the better part of last night reading what I could about shuffle and potential solutions. I had replaced the OEM twin turbo pipe with an alternate Y pipe that is separated further away from the turbo. The current one is from HKS and I had a previous pipe that was separated even further away, both have shuffle. I had heard that a divider can be welded in to the OEM pipe to remove turbulence, and figure that aftermarket pipes that are more separated would achieve the same thing. From what I read, most people with -10 turbos get shuffle due to their size, though it's a bit less common with -5s on a standard RB26. I think Nismoid mentioned somewhere it's because OEM recirculation piping is common in Australia with -5 cars. It seems that the recommendation tends to vary between a few options, which I've ordered in what I think is most feasible for me:  1. Retune the MAP or boost controller to try to eliminate shuffle 2. Install OEM recirculation piping 3. Something called a 'balance pipe' welded onto the exhaust manifolds. I don't know if kits for this are available, seems like pure fabrication work 4. simply go single turbo My current layout is as follows: Garrett 2860 -5s HKS Racing Suction intake MAF delete pipes HKS racing chamber intake piping hard intercooler piping,  ARC intercooler HKS SSQV BOV and pipe Haltech 2500 elite ECU and boost solenoid/controller HPI dump pipes OEM exhaust manifolds HKS VCAM step 1 and supporting head modifications Built 2.6 bottom end All OEM recirculation piping was removed, relevant areas sealed off I'll keep an eye out for any alternative solutions but can get started with this.  Only other question is, does shuffle harm the turbo (or anything else)? It seems like some people say your turbo shafts will explode because of the opposing forces after a while and others say they just live with it and adjust their pedal foot accordingly.
