Nitrous tips?

[Will]

I just pick up an NOS nitrous systems for an 86-93 5.0 brand new on Ebag for only a couple hundred bucks. It only has the pill for a 75hp dry shot. Any tips for using this on a 2.3? I plan to tap an extra throttle body I have an introduce the NO2 before the throttle blade. I have a Walbro 255lph pump, 35# injectors and a LA3 ECU. Any tips or concerns I should be worried about spraying a 2.3 turbo motor?

Nos

I don't know too much about mixing nitrous with forced induction but i do think the 75 shot is a little too much, at least without increasing fuel especially on a dry system. Get an adjustable FPR and i'd say get your fuel to about 45psi. Your probabbly better off calling NOS themselves, usually their techline should be able to assist in this a whole lot better. Make sure you tell them you have a low compression motor with about a 15 psi turbo. They'll probably say your crazy but then they should help.

Personally, i would get the smallest shot kit (25hp i think) or jet and i would plumb it into either the intercooler on the inlet side so that the charge also gets cooler through the IC or somewhere before the second ACT sensor, ...you did install this sensor with your LA3 swap right? I would make sure you have this, espiecially with drastically changing air temps. This way your using the nitrous to cool the charge rather than raising compression/efficieny.

But if you want the nitrous to improve combustion efficiency (like it was intended) then you'll definalty need to add a lot more fuel. Like i said, talk to NOS.

Intresting ideal, introducing the NO2 at the inlet of the intercooler. But wouldn't this actually raise the NO2 temp being forced thru the itercooler and break up the effect of the NOS nozzle? I didn't know nitrous would raise my compression ratio.

well i know that when you have a regular intake with a wet system there is always a chance of puddling, i would think that with all of the restrictions of the intercooler, this would increase the chance. but then again, i cant even get my pos to run.

NOS

Will, did you ever get nitrous hooked up to your SVO and what did you have to do?

[kiwi]

naw...

wouldn't spray it dry......what did happen?

[Will]

turbizzy, well yes, sort of. Hooked it up but never ran it. I blew a HG and sold the car to Pat. The install is pretty simple just like a 5.0. only exception is the WOT switch, use the two bolts on the side of the intake to mount it. Due to the vacuum lines being on the fire wall you have to fine somewhere else to mount the soleniods unless you move stuff around. I mounted mine on the passenger side inner fender next to the stock boost thingy. I will try to dig up some old pics for you.

i am no expert on the 2.3 but i have installed this same kit on a couple of dozen 5.0's. the 75 pills would be too much(my opinion) for the svo. Rejet the system for a 45 or 50,if not smaller, The pills are available from an nos dealer. I have done this 50 shot on blown 5.0 setups and worked pretty good. As for the full throttle switch- i always used a relay with a switch to the horn button to activate the solenoids. in normal mode the horn works properly and in fun mode it fires the nos solenoid. The dry kit works great but be careful.

I blew a HG and sold the car to Pat.

Oh, is that the one that blew up or something? Damm, that sucks b@lls. At least Pat will take care of it. Still would like to see some results with NOS on a SVO though.

I have a 75 wet shot on my LX (2.3T). I wouldn't be able to bring myself to run a dry setup but I've heard of several guys that have run 100 dry shots w/ no probs. W/ a dry setup I'd def do my tuning on a dyno w/ a wideband sensor taking measurements.

I do like it, talk about zip turbo lag and tremendous torque. I have a MSD 6al running things, then when I turn on the nitrous it has a MSD box that turns on the nitrous at 3k and off at 6k, and another MSD box that retards the timing when the nitrous is on 4 degree's.

It scares the crap outta me each time but I'm grinning ear to ear. I can be doing 55 or 60 and the car smokes the tires and I have to work to keep it aimed straight. I still haven't had it to the track for #'s so I've only played w/ it on lonely straight roads.

Were I you I'd be patient and buy some more jets and build up slowly so you don't hurt anything.

I believe Kiwi gained something like 60-75 hp on the dyno this past October from a 25 shot jet. Turbo's love nitrous.

DRY SHOT?

I think dry shots are a good way of getting rid of a motor. I have a drag bike that I have been racing for the past few years and I thought about running a dry shot on it, but I saw a friends motor detonate and blow holes the size of quarters in the pistons and destroyed the head at the same time. I went with a wet system (direct port) on the bike and havent had a problem with it. I am running a 75 shot and I pulled the head and the pistons still look like I just installed them with only a little carbon build up. I am going to build the same setup on my svo if I ever get it back for the shop. Oh yeah, I also have a schnitz nitros progressive controller running the nitros and the timing on the bike. Dont know how to make that work on the svo yet???

Nitrous Exprees wet kit

I have a Nitrous Express wet kit. Although I haven't installed this kit yet (something to do with the progression of my car, probably won't go on for a couple of years) there are some items of intrest that I have come across.

NX told me to install the nozzle(fuel & nitrous) within 6" of the throttle body, BEFORE the throttle body "blade". If a malfunction occurs, you will have some control over what goes into your engine. I have seen people drill a hole into the throttle body, but there is not much room there. NX told me to install the nozzle into the rubber hose inbetween the intercooler & the throttle body. I didn't like that idea too much, seemed flimsy to me.

So, when I do install the NX nitrous kit, it will be installed into a steel tube used with a "spearco" type intercooler set up I have.

The stock set up doesn't allow much room (none that would satisfy me) for the install with nitrous - but some have done it. I have some pictures of an install into the stock throttle body if you are interested.

Oh - my feeling is to use a wet system as well.
