ok i have a few questions that i seem to not be able to find a 100% answer.

question 1
what size line to run? i see -4 an or -6an. Should i match the fuel size to the N02 line?

question 2
what solenoids are best to run im looking at prices ranging from 60-160 for N02 and fuel solenoids.

question 3
I have been reading on a shot around 50ish run 1 step colder plugs. BUT timing dosent need to be retarded. Myth or Fact? i was under the assumption to retard

question 4
Anybody use this site to figure out what jets to get?

question 1
You mean the nitrous line from the trunk? Most common is -4an

question 2
In general people will tell you the NX lightning solenoids are the best american stuff.

question 3
Rule of thumb is to retard -2 for every 50hp, I was running 65 shot with -1 and it was running fine.

question 4
Yeah its a good site imo.

What engine is this going on? When you do install the kit get 2 sets of plugs and do a WOT run then shut the car off and coast to a safe spot and check all plugs, you will need to research how to read spark plugs, its kind of an art but will give you a good idea whats going on inside the cylinder. Remember not to hit the rev limiter and don't use it before 3000rpm. I had the 65 shot on a d16y7 with 170k miles lasted for a while, after like 10 months and maybe 20 bottles we put a cam on the motor, the thing spun a bearing on a N/A run not even running the nitrous at the time lol. Now im going with a forged internals block I had laying around and a JRSC with 75-100 shot.

1) 4 line is plenty

2) those noids are not the ones you are looking for

3) ZEX 55 shot on stock plugs and ignition timing is fine.

4) get a ZEX kit and be done :)

https://www.noswizard.com/ If you want to do it right. If you click in my sig you will see my set up. I just wanted a little bit of spray on mine for shits and gigs. I had less than 200 (IIRC) in my entire set up, it was fun while it lasted

question 3

For a 50 shot you should be fine with OE temp plugs and no timing. I ran a 60-65 shot and since it was my DD I decided to run a step or 2 colder plug and pull just a degree or 2 at the dizzy.

I used the jet sizing chart from the manufactorer I got my solenoids from. But I ended up using NOS' jets from summit That site has a lot of great info, but I dove head first into everything and learned lol
