I bought these off Tom (360 dynamics) about a year ago. I AM STILL GOING TURBO, and pushing my cars limits. I just won't be needing these for awhile and now that I have kinky motorsports I can use my resources when I want upgraded internals again. This is the original listing from Tom:
I have uprated to steel rods with wiseco pistons, thus my original setup is now for sale.
