You'll be lucky to find a shop that will do it. Most won't take on the 'risk'. Or they simply don't have the experience. Most shops view superchargers as taboo.
The meet info is in the Western Meets section. "Oregon in April". The meet this month is just Paul and his son (silverbullet) rolling through one weekend and back the next on vacation. I'm usually pretty open every other weekend anyway.
We're doing an L36 top end, a S2 L67 Gen3-GenV top swap, a GTP axle, and a couple other smaller jobs. 3 members plus a couple spouses so far (besides myself).
(but you need to order the red gasket maker, as I don't like to use the black sealant that comes in the kit)
But that doesn't make the technique clear on the one trying to push the other out. When and if you find a shop, I can explain that better and show pics.
Keep in mind, if you come here, I'll press the bearings at work (2 miles away) during the meet.
