Long but needed.....

OK i have a precision 6262DBB .68 turbo and wonted to swap out to a .84 AR. After talking with Jose @ Forced Induction He ordered me a Turbonetics 21598-62 .84 divided housing to use. Well it turns out that this wont work do to the dust shield. My 6262 dust shield sealing surface is not bubbled over like the 6265 or other dust shields so the turbin sits to deep in the housing and binds up.

So hear is the question rather then pull the turbo apart and swap out the dust shield with one of yours or one from PT what if i just got a dust shield from you (im local can pic one up) and trimmed off the sealing ring using it as a spacer over my dust shied? This would have the turbin sitting shallow in the housing just a hair.... that is unless your bubbled over sealing surface is more like a crush ring then it should be just fine.


What do you think??

Dave I completely understand what you are talking about. Unfortunately the only way around this is to buy our heat shield and swap out the Precision one. The part number on the heat shield that you need is 20297. They retail for $49.99.

If you had a Turbonetics turbo and was trying to fit a Precision housing on there it would be easier because all you would have to do is machine out the housing where the heat shield sits. Hopefully this makes sense.

So you don't think my idea of using your heat shield as a spacer is a good idea? I'm just concerned I would screw up the balance of the shaft in the process of taking the wheel off to swap out the shield. That's just not something I have done before and dont really know if it's as simple as mark the shaft and nut remove replace line back up.

Sorry I dont think your idea will work. And yes you are right when you take off the turbine wheel to swap out the heat shield you will have to rebalance the CHRA. I've heard of people having success by marking their parts and making sure they line back up when you assemble it back together but I wouldnt do it with my own turbo.
