got my extreme and need to clean -up smoke a bit.my ?'s are.what nozzle are most using?what nos solienoid?i have plenty of bottles.and plenty of -4 line and hobb switch also.was going to build my on and save a few bucks.also what jetshould i start with?thanx for any help in advance. chays

When i wanted to put Nitrous on my truck i also had bottles. so what i did was i bought the upgrade kit to upgrade a cheater system to a big shot. the up grade kit comes with the lines and the Noid you need and soem jets. perfect for what i need it for and a what i think a good price. it comes with the things you need if you already have the the bottles. Go to summitracing.com and do a search for this PN NOS-0025NOS thats the one i got. also also had to buy the fan spray seperatly. I got the blue fan spray but i was told that the brass one is higher flowing. the PN for the brass fan spray is NOS-13503NOS. I started in the .70s and worked my way up. the kit comes with the biggest jet of 120 and im not sure what the smallest was.
Hope its helps!

Talk to super diesel. I peiced my own system together but I used the noids he sells. They are .125 or and have a lifetime warantee IIRC. Good stuff plus you are supporting a vendor here. I'd personally run a 2 stage for drag racing but thats just me.
