Yea, Boulder Nissan and i have done just about everything to get it to stop smoking. We are still in the process of taking off the exhaust and seeing if it is one side or both. If its both, we might use oil restricters.

NOT the answer, don't do it. the kit is fine if properly installed and no component issues

well the exhaust is dry other then some oil around the rear of the exhaust (tips and mufflers) going to be putting some miles on the car to see if it will burn off the oil, if not the turbos will either have to be pulled out or we will try some reducers but no smaller then .045 as recommended by Garrett. ( yes i know Zivman, don't do it, but its worth a try. Also where are the reducers located on the APS kit, inside the turbos?)

Not worth a try, not going to fix the issue at hand and could potentialy cause more harm that good. if you take off the oil feeds to the turbos, the restrictors sit in the fittings on the turbos that those feeds attach to.

as I told you in PM, my exhaust was 100% dry - no oil.

sounds like a bad turbo/turbos to me. you should have them checked. dont waste ur time adding components that arent supposed to be there to begin with to avoid a problem. waste ur time finding the problem

Work with your shop on this, don't attempt to send them back without the shop you bought the kit from being involved. Shipping was expensive, I beleive around 300 bucks round trip as they need to be aired back and forth

Actually around $400, that's what GRD is charging me.

well they drove the car without the h-pipe so just on test pipes. No smoke even under boost, if any a very faint smoke from passanger side at idle. what do you guys have to think about this?

Was the car at full operating temp? If so it may just be burning off the excess oil left in the exhaust and you fixed the culprit somewhere along the line.

Yes it was at full temp, Boulder Nissan and another local TT 350z are going to do some exhaust switches to see if it is more noticeable with a "true" dual exhaust tonight, ill keep this post updated....

Well, Eric put my friends true dual exhaust on, no smoke.....i think we have this thing figured out. Either the x pipe in the greddy exhaust is causing too much pressure or there is oil in the exhaust that still needs to be burned off. Zivman, care to chime in on this?

I don't know what to think. You also said you saw smoke under throttle as well? I don't know how they are testing this, but make sure they take the car around town and have a chaser car following to make sure the car is not smoking before you call this cured.

If it is resolved, congrats. Maybe it was just install related (oil returns, oil level, etc)

Well, Zivman, you had the greddy evo 2 exhaust right? My installer thinks that the x pipe is making back pressure on the turbos which could be causing smoking. I wonder if you and i have had similar problems because the EVO 2? How long did you drive the car with the evo 2 installed? How long did it smoke with the APS?

Would HIGHLY doubt it is the exhaust causing the issue. That said, I think the move to something like the APS 2.5" would be worthwhile. Something else changed that would cause the car to stop smoking. It is not recommended, but the kit can be ran on stock exhaust and stock cats - I would think we both agree the greddy has better flow than that setup. I think it is just coincidence we both had the evo2

My smoking issues were from the first time the car started. With no boost. Just on a free rev when we came off throtttle. We chalked it up to a lot of new exhaust components... at first

i plan on getting some custom pipes to take out the x pipe and make my evo 2 true dual.
