Hi i have a 92 se spd which and i am putting nitrous on it but i want to know the engines potential . Does anyone know how much i can spray with and without a fuel pump without going over the limit?

Please help going to the track soon !

 

What kind of nitrous setup?

 

Why not do it right, get a walbro fuel pump and run a progressive direct port 100-150 shot? Assuming you run race gas and don't detonate and the n2o is installed properly the engine should handle a 150 shot. It won't hold it however if you do it alot and very often. But if your going to stick with the stock fuel pump go with a JWT n2o ECU.

 

I had a 92se 5spd with the jwt ecu/daughterboard. I ran a 255lhp pump but the stock injectors and jwt n20 program would only let you run 60hp (.042 nitrous jet @1000psi bottle pressure). I would run bottle pressure to 1150-1200 on a very cold day and that effectively makes about a ~80 shot and my engine would detonate very hard. I did this numerous times on accident but that motor never cared and compression never dropped. The ve30de is built extremely strong but with stock injectors and no fuel pressure increase it is difficult to run more than ~60 by just opening pulse width. I would like to note that the 60 shot dynoed about 80whp and 100wtq more than running without. Get a NOS fuel pressure switch that blocks the return during the window setting and run the 1 step colder plugs if you are going to use a fogger setup. But to really have fun all the way to 150 like nismo87se said, use a direct port.
