If you are going single, why not put the biggest one that can fit bottom mount? 6266
You can go with rods pistons for peace of mind but donít think standalone is necessary.

This is exactly the kind of post i wanted to see.
The shop think 6266 may be a bit big?
That is actually the turbo i asked them about installing.

No tuning issues at all?

Thx a million!
