I am now having one of these made locally by my fabricator. Still no issues?

Just a FYI.......A good budy of mine was having smoking issues with his Precision JB 6262 on his S and so he got a .075" restrictor after listening to a local shop. Well, I told him that wasnt the problem and low and behold, it kept smoking. I told him to move his drain to the girdle and it'll be fixed. Well, the shop didnt want to listen to me and so they moved his -10 drain from the top of the oil pan on the passenger side to the front drivers side top like IP does and it still smoked. Finally, after I had to drill it in their heads that the drain has to go into the girdle, they finally did it. Well.........What do you know? No more smoking and he even took the restrictor off and it still isnt smoking.
Look, I dont car what people tell you about the pan being ok to put the turbo drain on, but after many years hearing of people having issues with the pan drain, you would think they would start to listen to the people that know. I have had my -8 drain in my girdle since day one back in 03 and have never had one problem.
Bottom line......Put the stinking drain in the girdle and stop trying to bandaid the fix with a restrictor that may or may not fix the problem. Having a restrictor on a JB turbo can also burn the bearings out of the turbo. Would you rather have a $200 fix if the seals go out or a $600 fix if you burn the bearings up? There is just too much windage anywhere in the pan to have a turbo drain. I believe that when you put the drain anywhere in the pan, that drain is trying to act like a PCV port (like what big time drag racers do to their blocks to relieve crank pressure) and the air pressure backs up the oil in the line.

For turbos that are mounted lower in the chassis the use of a scavenging pump would be a good investment as even the drain line piped back to the girdle can be too high for proper sewer flow drainage.
The issue you are referring to is related to excessive crankcase pressure which is an entirely different story and this can be cured on most by equalizing the drain line to the crankcase. For those that have yet to tap the pan and have the skill to tap the girdle you cannot go wrong though.

Yes the restrictor was the ticket to get the smoking stopped. I cannot believe precision did not know this in the first place.
They are available now!

I agree that the girdle maybe the ultimate place to put the drain line and maybe more important to put there with a journal vs. a BB turbo due to the higher oil flow.

I now have a .030 nitrous jet installed in my setup (which is back on the road as of yesterday woot) inline with the .035 restrictor I had already. Not one puff of smoke so far. I think this is the ticket.

what's funny is that our cars don't look any more special than the pictures in the honda catalog. Just knowing the blood, sweat, and knuckle skin left under the hood that really sets it apart from 99% of other cars on the road.
