I've got a complete TNT F2 kit FS. Adjustable from 100-250 rwhp. I sold the "power ring" for the stock throttle body in exchange for a 90mm power ring for my 90mm TB. The 90mm ring will be sent in the kit in place of the stock one. This is the best nitrous kit for a LS-1 IMO. I've never seen any other kit out power TNT. Whatever jets you put in, is what you get in RWHP. This kit new is $850. I'll let it go for $750. It is brand new, still in the original box. This kit could be made to work for LT-1 cars if you bought the plate and jets for the LT-1. Selling the 90mm ring would cover the cost of that.

I also have 4 TNT direct port distribution blocks (polished) and 8 direct port fogger nozzles. Includes jets for 300, 400, and 500 rwhp. This could get you well on your way to starting your own direct port kit for any car. Looking for $250
