what is the limits on a NX wet kit that isnt direct port and how far can i go with a direct port

 

i think the stock motor can hold 75 wet shots. rebuild your motor if you plan to run higher shots

 

but say if i do a rebuild with forged bottom end how much can squeez on it with a wet kit thats not direct port

 

still cant squeeze much on a single fogger the nitrous distribution wouldnt be even to the cylinders. you almost have to go direct port for a large nitrous set up

 

the lowest you can squeeze on nx direct port is 75 shot. i would reccomend direct port to any serious nitrous user. single foggers are great but you cant beat the "hit" dp gives you. combine that with the even distribution of juice and you are doin something. i was using nx single, moved to the dp, now i have the nxl kit. best of both worlds- easy to instal like single fogger, has 40-60-90 jet options, and is still direct port. i distribute nx so if you are in need i can supply. i also have a never used dp kit mounted underneath a skunk2 manifold for a gsr? i bend all the lines and this is a beautiful sleeper style setup. btw- built block-dp, stock block- single fogger. you can get away with 75 on stock block though(safely)

 

what is large? some a 60 shot is large and some a 150 is small

but say if i do a build how much can i go up to with a single fogger wet kit?

 

my motor is fully built....and i wouldnt dare squeeze over 100shot. thats large for a 4cyl. single fogger limit is usually 75ish

 

becouse i have seen in the past other queezing over 150 hp into a gsr motor but it was built

 

but can you go higher then 90 hp on the nxl kit?

 

yes you can- the kit comes with the 40-60-90 jets though.

 

but i cant go higher then 75 with a built bottom end with a single fogger?

 

normally for a dry system, it tops out at 75 shot. the wet system is almost the same thing cept it has fuel to with the N2O, so distribution can be a problem as well. wet system tops out normally at 80 shot. direct port picks up at 75/80 range depending on the brand and goes up pretty high, up to 200 shot for some. which is plenty large for a Honda 4 cylinder.

i ran the 100-125 shot NOS plate system on my B18C1 last year for most of the year. i did rebuild it first though, Eagle rods, SRP pistons/JE rings, Ferrea SS valves, ARP hardware etc. ran pretty well and made some nice power increases.

i'm out of the N2O injection now, but if i go back ever it will be Direct Port system and only that. no wet system or dry system for me. though the NX wet systems are pretty nice i might add. if you want to use 100-150 shot then you need to go DP, NX or NOS.

if the tuning is correct (bottle psi, ignition timing, plug gap and type, FP set correctly etc) then you can do 150 shot on a B18C, though if the C/R is higher you may be pushing it on pump gas (93-94 octane). i ran 125 shot with 11:1 C/R on 93 octane for a couple months at the end of last year. everything held up fine including the stock sleeves. either way caution is needed when using the larger injections, you don't want to melt something or put a hole in the pistons or crack a sleeve.

 

about how much whp where you pushing with that setup on spray?

 

so what wouold you recomend for a fully built b18c1 boosting 10 psi if i wanted to go direct port. 70?

i'm not sure exactly cause there aren't many dynos around here where i could just hop on and tune etc.

i estimated 175 WHP N/A and 265-275 WHP on the bottle, but i don't know for sure how much power was there. it was pretty quick though, never lost to anyone on the street though there were some close ones.

but i was running stock cams, stock IM (to use the plate system), stock TB, stock fuel rail and injectors, and stock ECU. so the power was made by the headwork, the C/R, the cam gear changes, and the bolt-ons. and the N2O injection of course.

honestly i would recommend more boost!

using N2O with boost can be tricky. when boosting the N2O injection size normally doubles, so if you want to run a 70 shot then it's more like a 140 shot with the boost you already have. i highly recommend more boost and no N2O, it's the easy way and normally much safer. if you're motor is fully built then you can run 20-25 psi and make plenty of power, even if it requires race gas and better tuning.
i'd go that route than adding a DP N2O system to the boost.

you can; but it's not as effective as going direct port for larger shots.

 

see the thing is the kit i have now is only half of a NX dual stage but onely the first stage is hook up so should i just trade the second stage in for the dirent port upgrade or go put the second stage in?

 

what do you think about that??

 

personally i'm not exactly sure what you mean by "first stage" and "second stage".

maybe that's cause i've never used and NX systems before.

you're running a wet system right now, but only the "first stage"?
do you mean that it's a dual stage N2O injection system, meaning that it injects let's say a 50 shot first and then an 80 shot?

that's what i'm getting out of what you said. not quite sure what you mean.

 

i used and recommend n20 hehe. direct port or single fogger, its your choice.

yes thats what i am saying so i can spray a 50 and then a 80 on top of it it has 2 nozzles and 2 pairs of soliniods but i only have one set on there now becouse they sent me the wrong set of n2o and fuel spliters

 

the first thing that comes to mind about the "2 stage system" is that if it's a dry or wet system that in total is more than an 80 shot, there may not be proper distribution/atomization through the intake and IM/runners.

so if you have say a 40 shot for stage 1 and then a 70 shot for stage 2, all together it equals 110 shot. unless you're going to shut the stage 1 down when the stage 2 comes on, kinda using it as a traction control/progressive injection system.

really the only way to use more than an 80 on a 4 cylinder motor is use the DP systems. pretty much cause of the proper distribution and atomization that the DP system has, that the Dry/Wet systems normally do not have.
