I have a 38mm on right now and I plan to upgrade. The flanges on the WG is the not the Vband flange. I've seen adapters for the one side of the flange but not for the other. Would it be better just to weld flange welded on?

Can you go too big on WGs? I have a 76mm Precision billet turbo, with .96 exhaust, on a 322 mod motor. I'm installing a ams1000 with c02 and need to upgrade my WG. I was looking at some of the 60mm for sale in the for sale section. Would those be too big? I plan on running up to 25psi.

For this set up a JGS 40 will bolt on in place of the 38. We have run a 302 with a 76 and a JGS 40 without boos creep.
Unless you have boost creep issues the 38 or 40 should be enough.

I would never run an engine of that size with a single 38 or 40. m,It ight be fine on the dyno but you will be very close to maxing it out, all it takes is a little extra load and you will overboost. Could cost an engine.

Thats one reason why I'm need to upgrade. It got stuck on the dyno last year.
