Let's Talk N02
I've been reading around about installing nitrous in our cars (in my case a 250) and had a few questions.
In regards to this kit 4-6 CYLINDER EFI WET BLACKOUT NITROUS SYSTEM
http://www.zex.com/zx/4-6-cylinder-e...-systemtmhtml/
1.) Will our stock fuel pumps be able to handle 50 up to 75 shot? If not, what fuel pump would you recommend. 255 LPH
2.) Will our spark plugs need to be upgraded going down in a heat range? If not, which ones would you recommend?
3.) Where do you tie into the fuel system and would you need a special fitting? Here is what is says comes with the kit for the fuel:
STEP 8: Install Fuel Delivery Line
The ZEX™ nitrous kit comes with several fittings that will allow you to decide what the best solution is for your vehicle. If you would like to use the fuel tee fitting, ensure that the fuel line pressure has been relieved and then cut the rubber fuel line. Insert the barbed ends of the fuel tee into the rubber hose ends and secure with the provided hose clamps. Using an appropriate thread sealant, install the 90 deg. -4 AN fitting into the threaded hole. Another option is to remove the fuel rail and drill and tap it for the 90 deg. -4 AN fitting. Pick the spot you would like to drill and mark it. Using a 11/32 drill bit, drill the hole and then tap it with the supplied 1/8
NPT tap. Using an appropriate thread sealant, install the 90 deg. -4 AN fitting into the threaded hole. Before installing the fuel rail back on the engine, ensure that all metal shavings have been cleaned out. There are also certain vehicles that have a -4AN Schrader valve fitting, factory attached to the fuel rail. Once the valve core is unscrewed and removed, with the tool provided in the ZEX kit, this factory fuel rail fitting makes for a very clean and easy hook-up for the nitrous system’s fuel supply hose. Finally, a 1/16 NPT to -4AN fitting is also included for easy connection on vehicles that contain fuel rails with a 1/16 NPT access port. Once the fuel fitting
has been sorted out and installed, connect the -4AN, 36” hose assembly to the fuel fitting and the fuel inlet on the Nitrous Management Unit. This completes the fuel connections for the ZEX™ 82021 Nitrous System.
Before you start flaming please remember this is just for fun to start a conversation and curiosity.

^Not just our engines, all engines. Your best bet is to weld in a bung into a SRI pipe and run it near the TB. There might be some useful info in here : https://www.clublexus.com/forums/per...de-thread.html

Ok I found the post that talks about the fuel setup. HKS350 says: "This is wild!I just finished installing my NOS kit kinda! I have to order some factory SST pressure fitting for the fuel. This way I can use the factory quick connectors. IF I get these parts in I'll be spraying by this weekend!!!!!!!"

Do you know what SST pressure fitting he is talking about and where he's talking about using it?

For a 50 shot the factory fuel system should be fine. As far as the plugs go you probably dont have to drop but if you go out to the 75 shot it might be worth dropping a stage colder. Anything larger then that much of a shot though and your going to have to start changing things up.
