I guess I'll describe the kits to ya lol
B&M - Seperator plate basically, firm shifts, doesn't fix VB problems or anything inherent. About $40
SK - Rebuilds the VB for durability so it'll last. You can make this setup to shift firm with larger feed holes (I have a copy of the sheet), larger boost valve, and heavier accumulator springs. About $40, then add boost valve like $25, and $10 for the accumulator springs so then you're around $75.
PSK/HD2 - Best setup, gives durability and firm shifts. Has parts like the SK does to make it durable but all the performance upgrades to make it kickass. This kit is about $80 from TPUSA.
That help some? :think:
