what fuel system upgrades if any for 75 shot zex wet

Just wanted to know what fuel upgrades are necessary if any to run the 75 shot zex wet kit. I plan on changing the fuel filter, and have ignition covered, just want to know what is necessary for fuel system.

Thankyou

Thanks, thats what I figured. No fpr? I may just get a gauge to make sure I am getting sufficient fuel.

I would suggest a fuel pressure regular for your stock fuel pump, and depending on the output maybe new injectors- but only if you're going to have future modes. just remember that with more fuel you need more air so you might want to do a few induction modes

I already have those upgrades, I just wanted to know about the fuel upgrades and what was necessary.
My setup
2000 prelude base
I/H/E/
Tuned VAFC (Running Rich while on Nitrous for Safety)
ACT clutch and lightened flywheel
MSD SCI Ignition w/ blaster 2 and wires
Zex Spark Plugs
Zex Wet kit currently running 55 shot about 6 bottles in a couple years no problem
Dynotune bottle heater

Ran compression test and had 3 angle valve job before installing zex kit.
dynotuned about 6 months ago with vafc to be running rich on nitrous wot. Running about 11 a/f ratio on the nitrous.
Figured it should still be running rich w/ the 75 shot, and I will be checking the plugs just to make sure. The dyno place here is garbage and they do crappy work so I don't want to trust them again. I am also replacing the plugs, and wires, as well as the fuel filter. If you say the fuel system is good enough to handle the 75 shot, I will just get a gauge to make sure its up to par. If the fpr is unnecessary I'll just get the pump for more assurance. I have had no problems with the zex kit, I think it seems very safe, and there shots are at the crank, not the wheel so its really like a 65 shot of nx. Let me know if there is anything I am missing

What I'm doing
want to increase to the 75 shot with the zex kit
got msd 8982 start/retard controller to retard timing 3 deg while on the juice
got msd 8969 digital rpm window switch to keep traction and cut of juice before the rev limiter

Wondering what the opinions are about how safe this will be and any other suggestions I should use to increase my odds of success. This is a daily driver and my baby, I just want more power safely.
If I had the extra money I would upgrade the fuel system, but from what I hear that is not necessary with the ludes until 100 shot.
Will probobly get a fuel safety switch and new high flow fuel pump as well as FPR to beef up my fuel system.

Thanks in Advance

All you need to do with it being a wet kit is run a walbro 255 fuel pump.

There's a nitrous shop in my old town. The owner has been using and installing nitrous for years now. When i talked to him he said that no modifications were needed until you used a 100 shot. But like the guys above me said, it's way better to be safe than sorry. Your stock fuel rail is good for like 500 hp, but upgrade that if you want the bling. Your pump should be good too. I would be most concerned about clogged filters and gummed up injectors..

Yeah, I'm replacing the filter, not sure how difficult it is to remove and clean the injectors though. Already have the fuel rail. Thinking of getting the pump just to feel better.

Thanks a lot.
