hey all,

my car is occasionally blowing smoke when i drive it in the mornings and after work etc. so if its been sitting there for a while... *cold* i guess you could say. im guessing its just running rich and needs a tune? any1 confirm this? would a remap help this as well?

also in the mornings i get a weird knocking/tapping that im guessing is coming from my turbo, not to sure. it knocks when the turbo winds up... but as b4 when she warms up its goes away. this has only just started recently. havent lost any power though. some1 said it might be the lifters???

cheers for the feedback.

The knocking noise I would put money on it being lifter noise in the head which goes away once the hydralic lifters pump up and the oil thins a little.

The smoke can be a worry. If its blue or white then its a sign of either the turbo seals, valve stems or headgasket being on its way out. If its black or brown then its just fuel.

white and blue = bad.... white can also be steam from water condensating in your exhaust over night.... When you smell the exhaust does it smell normal, just with white gas coming out, or does it smelly shitty and oilly???

If its going away after driving, as in when it warms up, could also be a worn engine. When it heats up, the gaps close up a bit, maybe letting less oil into the combustion camber.... maybe do a compression test to check it out

probably just condensation in the exhuast... You can buy a compression test kit for around $50 I think.... I got mine ages ago so not sure what there worth these days.... Do a search on how to do one... Quite easy...

Depends on how your engine has been treated in its lifetime as to if its flogged out or not... Realy well maintained and tuned examples could live forever (well not quite, but you get the idea).

If you have heaps of mods, or even just the normal exhuast, boost and cooler, it is worthwhile getting it tuned...

      Steps to DIY sanding car back ready for respray....

      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.

      Can you mount the ATTESA pump in other locations?

      That worked out PERFECTLY! Thank you big time to JJ. He was able to swap me his stock diff. He drove all the way to me as well. Killer! Removal & install was pretty straightforward. The diff itself is HEAVY. So that’s a 2 man job.  Man does the car drive nice now! Couldn’t have worked out any better 👌
