im looking at throwin a 50 maybe a 75 shot wet zex kit on my build and i have a couple questions for u experienced folks.
im running 82mm type r pistons in a stock sleeve ls bottom end. should i stay more on the 50 shot due to cylinder pressures or is a 75 shot not pushing it that much more?
i am possitive that i want to run a wet kit simply for more tuneability and in my opinion “safer” because you set the system so it wont lean out the motor not depending on a sensor to play catchup. but going wet requires additional fuel lines. is it possible to just splice into a fuel line after the fuel pump and T fuel lines there or is it absolutely necessary to run a completely seperate fuel system just for the fuel side of the nitrous kit?
Any body that can help me with any of these questions I would love to see a responce thx guys

for fuel your going to need a good fuel pressure regulator like a aeromotiver 1:1 that you can pull fuel from…i dont think it matters much about cylender pressure and what shot you run that will be somthing you need to talk with your tunner about …as long as the car is tuned you should be fine…
ok but about the fuel system. do i need to run seperate fuel lines pump and filter from the gas tank that are dedicated to the “wet” side of the nitrous system or is it ok to simply “T” off of the existing fuel system after the fuel filter to supply the fuel to the nitrous setup
idk why ur saying that, a wet shot pulls fuel and mixes it with the nitrous before spraying it into the motor, most people build a custom bolt that goes into the fuel filter to get the fuel flow required for the wet shot
You do not need to run a new line from the pump to your fuel solenoid. There are fittings that can be bought that attach to the banjo bolt on the outlet side of the fuel filter or if you have an aftermarket fuel rail you can use the auxiliary fuel port on the rail as your source.
I would highly recommend a high flow pump on any wet system just for reliability purposes but if a high flow pump is not in the budget then a stock pump with aftermarket fuel pressure regulator would be fine for no more then a 75 shot.
Nitrous is fun just be smart about your install :burnout:
thanks man thats what i was lookin for… i have a walbro 255 im droppin in when the motor and everything goes in this spring. not sure if ill go with an aftermarket fuel rail or if ill go with the banjo bolt adapter but thanks for clearing up the two options i have. any links on where to get the banjo bolt adapter??
Its not necessarily an adapter but just a fitting I guess. Just pull the bolt on top of the banjo bolt and match it with a AN fitting for your fuel line.
if you are running upwards of 12:1 compression, you should get that tuned before you step up to a 75 shot. and i would run race gas with it too, especially on a hot day.
I have a stock b17a1 gsr in a 91 DA9 and I always wanted to spend at least 10,000 on a great turbo kit, built motor, and great tune. But after talking to people at street races I’ve decided to go in the nitrous direction. Its a fraction of the cost of a good turbo system and it gives you the same amount of horses if not more. And the fact you have the option when you want to run nos it not as lengthy on your engine as a turbo. Its a good direction to go if you want to win races, just make it a full throttle switch and don’t mis-shift!
when staying as stock as possible (I have a bone stock 91 ls) whats the recommendation when wanting to spray? my motor is around 185k miles but I did a compression check (180 on all cylinders) and I will be doing a tune up. Im trying to stay as cheap as possible but I was thinking of going as big of a shot as a 75 wet shot. if not that large then sticking with doing a 50 wet shot.
I pulled the motor and bought a new water pump, timing belt, timing belt tensioner, oil pump and new valve cover, oil pan, intake manifold, exhaust manifold, rear main seal and cam seal gaskets to tighten up the seal but with my build budget cap rapidly approaching I didn’t leave myself with much in the way of wiggle room on the funds.
guess im looking at thoughts/ recommendations on if a 50 or 75 wet shot is safe enough to use on a stock motor? I will be buying colder plugs for this but wanted to stay away from upgrading anything else if I could help it.

I ran my setup for a while spraying a 100 shot on a bone stock jdm b18b, I retarded the timing 3 degrees, ran Zex plugs, 93 octane, upgraded the clutch and flywheel, and it ran great. Then I put an Xsi trans in and ran a 13.9 @ 101. I think if I were to continue running nitrous long term, I would invest in some ARP headstuds.
Nitrous is great. Its reliable despite what alot of people think. You just have to run a stock ecu. Oh and be sure to invest in a gauge and a bottle heater so you will get the most out of each bottle.
Just retard the timing. Tuning is only required for dry systems. But the issue with tuning nitrous is the bottle pressure will always vary on each pull so its very difficult to get it dialed in perfectly. Thats why wet kits are great, and wet nitrous is good to a 100 shot. any more than that you get issues with the fuel atomizing properly out of the nitrous nozzle so you would need to switch to dry.
