Pankl has made shorter rods for the GT3, but they are Extremely expensive IF they are even available.

Why run so much stroke/rpm on a turbo? If possible I would opt for a bigger bore and shorter stroke to get some longevity and lower some of the cost.

On 3.8 turbos that have seen high rpms and high boost experience cracks at the main webs. They form at the thin sides of the case thru bolt holes and run from the centerline of the case all the way up to the head stud bosses. #7 main on the #123 side has experienced cracks as well. Longevity is definitely not a term I would use with this particular build.

I'm not trying to scare you. I am trying to hint that there are better alternatives. Besides, if you are short on displacement, why not crank up the boost a bit?
