i want to hear some stories on what kit you bought and thoughts on the install. i am looking at a couple of options here


one :
$522
basic plate system set up like a carbed nitrous kit:

http://www.barrygrant.com/nitrous/default.aspx?page=97

this is what i was leaning for until i saw the nx kit which i like the looks of better, but its 200+ more for the nx kit..


two:
$757
http://www.nitrousexpress.com/Pages/gm_tbi.htm

i like the fact that this kit does not modify the height of the top of your engine, usefull for those running a 3in air filter...
also like the fact that it has adapters for threading the nozzle into the gold ring. also one problem with the tbi unit is the lack of a schrader valve. this kit has a T fitting schrader valve. so its basically a twin nozzle kit with a valve for a test fitting included. otherwise like on the others im gonna have to either T in with my own stuff or use whatever tbi specific parts they include (nitrous works only.., the other ktis will get a standard brass 3/8 tee)



the next two are super cheap for some reason.... :

http://www.dynotunenitrous.com/store...?idproduct=215

this is the dyno tune kit, it has the "adapters" for threading into the gold ring also... cost is $399 ????????????????????????????????

http://www.nitrousoutlet.com/catalog...roduct_id=2529

this one also comes with the nozzle adapters, which make it appealing but the price is more than the others at $580



any body got any input on which system i should go with? i wont be purchasing until the end of this month so i have some time to look around for reviews on the various brands and whatnot..

i have a tbi NOS nitrous kit. i love it got it off a member here for real cheap. set it up within 2 days taking my time and only working like 2 hours a day. the tbi plate is nice if sprays where you want it to i wouldnt do above the injectors but thats just me. plus my 14x3" air cleaner still doesnt touch my firebird roof

sp63

cool. good to know. the nitrous works kit is cheaper than the Nos tbi kit. by say 50 bucks....

it is also a spray bar / plate design.


also theo ther kits with the nozzles dont spray above the injectors they spray level with them so fuel and n0s isnt going on the wiring of the injectors. i was wondering about that also but i found out.

vipershark11

iTrader: (6)

idk id say go with the nitrous works tbi kit ive looked at it before but ended up just getting the NOS kit because i got it for one hell of a deal but go with the plate youll be a lot happier its much easier to install and it all set nicely.

sp63

cool man, see i was debating on if the spray bar would atomize the stuff as good as a nozzle but i guess it does. so far its lookin like imma get the nitrous works kit.

The NX kit may not have the plate, but from what I've read, NX stuff is a step above the other brands.

As you mentiond, I'm already eating into my hood liner with my 3" K&N, so adding anymore height to my TBI is not good unless I want to drop money on a new hood.

sp63

well i dont have a hood liner anymore. that frees up like an extra inch of space.

also, if i do get the spacer piece, i can always remove the gold ring above. they are about the same thickness...

interested in kit..i have an 89 305 TBI camaro. is basically stock. would this motor handle it and what exaclty would i need to get this to work? pics?

vipershark11

iTrader: (6)

everything is included in the kit that would make it work. basically hook it up and wire it up fill the bottle and have fun. o yea retard the timing some and get a step colder spark plugs. id say to be SAFE a 100 shot is fine especially on the stock pump. i ran i think a 130 shot last year on my stock LO3 with stock pump and it was fine im upping to 150+ this year with a 190lph which should be interesting and yes idc if the motor blows.

sp63

man i wasnt gonna buy my kit till the 27th of this month when i get paid but my mom said i could put it on her CC and then pay her, but i kept reading abotu bottle heaters and pressures and whatnot. and i think those are VERY essential things now. from what i have found a gauge and heater is going to cost about 160 extra. i cant swing that right now (have to limit 500 per check basically, rest goes to savings). anyways, i got to thinking hmm... everyone says the nx kit is great blah blah blah, it uses the dual nozzles into the tbi via the gold ring, OK, the Dyno tune kit uses the EXACT same setup. for over 100 less...

i have money ion my hand + my moms CC i can get the heater, gauge, and kit all in one go. only other thing is the window switch. which i also think is nec. but its another 150+ . damn.


so heres my list right now:


kit $389
http://www.dynotunenitrous.com/store...?idproduct=215

Heater $109
http://www.dynotunenitrous.com/store...p?idproduct=17

Gauge 58
http://www.jegs.com/webapp/wcs/store...53511_-1_11289

i think this would be a good setup aside from the fact that you have to roll into the throttle to get over 3000rpms before flooring it.

sp63

http://www.harrisspeedworks.com/shop...cat=364&page=1

this kit looks good, has GOOD reviews on ls1tech, similar price, AND includes the gauge....

interesting.


edit: the bottle heater is 20 bucks more here but looks better than the dynotune stuff.... plus the website has good reviews. which is a big plus i think. and its all in my price range.

anybody have any engine pics of this nitrous setup? basically buy the kit wire and screw everything into my stock lo3 and go? that sounds WAY to easy. so basically headers exhaust better air intake and nitrous and you can have one hell of a 305 tbi? what kind of horsepowe?

SpitotRs305

how many times can you change jets?...

1991CamaroRslow

iTrader: (3)

Stay away from the Dynotune stuff, I've seen 2 Dynotune solenoids leak and they apparently have no customer support. A bottle heater is NOT that necassary. Run hot water over the bottle in your bathtub before you leave and wrap it in a towel. If you're in town and you need to get the bottle warm, throw it in the floorboard with the heat on it for a few minutes problem solved. As for the jets, you can change then indefinetly as long as you don't strip anything *which you shouldn't*.

SpitotRs305

i meant you could have as much HP out of a N02 system as you wanted as long as you could change jets... not how many times can you acctually change jets

sp63

car has no heater core.


htr is nec. lol.

vipershark11

iTrader: (6)

ok well i recently redid my setup and neither the purge or the wiring for any of it has been done so this is how it looks as is. and ill give a before pic where they were over the exhaust manifolds.
new setup:


old setup:


im about to dyno my car in about a month id say but im hoping with a .067 nitrous jet that ill hit 300 to low 300's whp and well over 400+wtq

sp63

what all do you have to to your car?
basically i have.. the intake and a shift kit with someo ther trans work.
what kind of mileage is on your car? did youh ave to replace your fuel pump? what fuel pressure are you at these days? and uh.. what is your fuel pressure saftey switch set to (if you have one). i was wondering if the carb (5psi) switches could be adjusted up to like 12psi.
did changing to headers make a big diff on/off the nitrous ?

vipershark11

iTrader: (6)

im running a .067 nitrous jet
im running 13 psi of fuel pressure
i have a 190lph pump to support all this
i havent run it with the headers yet but i will not be able to tell the difference since im getting lower gears and upped the jets.
i basically have intake and full exhaust
56k miles on my car.
no fpss for me

sp63

ok i have 156k miles, LOL.
i do think im gonna get a fuel pump in the next few weeks.

i want to do gears but i dont think its worth it on the stock rear end. it WILL eventually break.

liquidh8

Wha fuel jet are you using with a .067 nitrous jet? That is good for 200 hp that size jet. I have a .057 and NOS says that is a 150 shot or so, maybe 160. Also, what fuel jet you running, are you using a TBI plate?

1991CamaroRslow

iTrader: (3)

Directly from NOS, a .070 jet is a 150 shot. NX jets differently theres are always lower, Nitrous Express is even lower still. The headers will make a very big difference on these cars with nitrous because the factory log manifolds suck horribly, nitrous just makes it worse. I spoke with a representative at NOS about my 5151 TPI kit and was told that a .078 jet was a 200 shot and the .073 jet I was running was around a 180 shot. The TBI kit has shorter lines to the plate but this isn't going to make a hugely dramatic difference in the jet size, just how hard the nitrous comes on.

liquidh8

Oh ok, you have a tpi kit. I talked to a NOS rep about the TBI plate, he said I should max it at 150. I have the BBC plate w/2 in bores. I have cheater noids on it, so the capability is there for 250 hp, but I can't with that plate. I may use the squarebore cheater plate under the tbi adapter. Haven't heard anyone talk about how that worked out though.

1991CamaroRslow

iTrader: (3)

The plate under the adapter will work out fine. Also the passages in your cheater solenoids are quite a bit larger so that could effect the jetting of the system. I'm fully maxed at my solenoids by the .073 jet. I have a set of large Top Gun solenoids that will flow alot ready to go in along with a .078 jet and we'll see where that puts me. I've sprayed this TPI engine into the low 12's on a bone stock long block with high miles. This year I'm gunning for 11's.

liquidh8

Cool, good luck. I just have to get to the track. Should be in the low 12's with the juice. I ran a few low 13's last time out, with street tires on 17 inch rims @ almost 4000 lbs with me and a full tank. I've since put a glass front bumper on the front, and did some more tuning. I few more n/a runs then I'll try the n2o.

vipershark11

iTrader: (6)

i do have the tbi plate. i have the cheater solenoids that came with the kit. i havent tried my new jets yet and i dont remember which fuel jet i put in there but i calculated it. also im putting in a stock 3.08 posi drum rear rather than my 2.73s i dont want to mess with internals or disc conversions just yet. so if it blows it was well worth the 100 i got it for.

1991CamaroRslow

iTrader: (3)

Vipershark those aren't the cheater solenoids, those're the powershot solenoids. The cheater noids are bigger.

sp63

so.. back to my thread. in the next few days im gonna drop cash for the harris speed works dual nozzle kit and heater.

im getting that cant wait feeling in my skin....

hah

vipershark11

iTrader: (6)

oops my bad i dont know why i thought otherwise. so how much can those flow max?
----------
once you put the nitrous on youll be hooked and always want more trust me in the beginning i denied it and said id be happy and i was for 1 summer my friend told me id want to up it i said no. now look at me. im a nitrous junkie

sp63

im getting there. lol.

i bought me a fuel pressure guage today, now i have to figure out how to watch it while i go WOT...

im feelin, run it on a line up by the side mirror lol.

1991CamaroRslow

iTrader: (3)

You should be able to run it up to the cowl, you really only need to watch it a few times, just get going in 3rd at full throttle and spray it, that'll show you the minimum it's going to run down to. Vipershark your solenoids have .073 passages inside. Going over .073 on the jets really doesn't help unless you upgrade solenoids.

vipershark11

iTrader: (6)

ok then my .067 jets will be plenty enough for this year.

sp63

ok i got it installed (the guage) today and my fuel psi is set on 12 psi. i have no way of knowing what it goes to when i drive until i get the lines to run it up to the cowl area. gonna duct tape it to the window LOL.

how much of a drop can i expect when i spray the first time? im debating on buying this like. 30 dollar in line pump from autozone, do you think it would make it safe?

1991CamaroRslow

iTrader: (3)

The 30 dollar inline pump will probably just hinder your ability to pump fuel. They're only made to run like 7psi tops. If you want to do an inline get one of the Walboro 255 regular pressure pumps, apeusa sells them and you can get them elsewhere online at a good price.

sp63

thats where my gauge was, i ran a line from that t up to my cowl and mounted my gauge (with ducktape) to my window and i did some WOT runs up to like 105mph, quick question, when it was mounted down like in the pic, i got 12psi, now its mounted at the cowl and i have 11.5psi. is that a sign of a bad pump?

sp63

i left my gas cap loose to relive pressure during my gauge relocate. its up to like 11.75/12psi now.

srv010

Its now 2018 and I'm not able to find a TBI injection Plate to under my TBI. I have an 1989 firebird trans am. I bought a kit from summit and it came with a plate for TPI not my TBI system. What am I to do?

I'm using a Cold Fusion nitrous kit on mine. Single fogger nozzle but they have plates if you want to go that way. I am very happy with the quality and durability of the components. Been on the car for around 10 years or so and no problems with solenoids or any other component.
I am running EBL flash ecm and it has great N2O control features and can be configured for TBI cars. Check out dynamicefi web site for info.
