exhaust housing wastegate hole

[eqs_gn]

I have a turbo with a Precision exhaust housing. The wastegate hole has been enlarged by the previous owner to 1.25" (1 1/4").

I have an exhast elbow with a large puck sized to 1.35".

The problem is that when the puck is closed it does not fully cover the hole which leaves a 1/8" gap at the rear of the puck

The wastegate hole seems round but not centered.

Can I use a sleeve to de-crease the diameter of the wastegate hole?

Any other options?

Thanks,
Ernest

Somehow attach a larger puck to the face of the existing puck.? New turbine housing is only around $100. Maybe try a larger A/R. ? Like .85

Seems like everyones DP's have the puck placement in a slightly different area, even THDP differ some by pipe.
Best thing to do is get another exhaust housing and have it ported out to match your DP puck placement.
