Default Isf nos kit
Where can I find a nos kit and the pricing? Are there any requirements needed or is the kit just a bolt on

There is not a bolt on ISF nitrous kit... you will be taking a v8 efi kit and custom fitting it to your isf, this takes some know how and depending on how nice or rigged the install. It can make a difference in reliability and how finished product looks.

This is my set up... https://www.clublexus.com/forums/is-...-100-shot.html

Both would help, since I am trying to find the right jet setup for the nos kit that I am about to purchase, and my adviser requires this info.

Low pressure is 400 kPa.

High pressure is 4 - 13 MPa depending on what the engine needs.

I doubt anyone would really know, unless you run the same kit & jetting as a current or previous member that had it working.
Depending on the fuel used the only way to jet is with a wideband installed or on a dyno with a wideband and a big set of jets. Trial and error, process of elimination. The companies tech line and an ISF service manual would probably be in order.
