I have a 2.3l. I’m going to put a 302 in it. But before I do the 302 I want to put the 2.3 on NOS.

So how much NOS can I put in the 2.3 and mike it last a ¼ mile?

 

Well for starters NOS is a company not something you can put in your 2.3 or any other engine. Hate to be a jerk about it but you sound like a ricer when you call it "NOS".

The general rule of thumb is the amount of nitrous you can add is half what your engine puts out stock. Some people say anything less then twice what it puts out stock but I have seen first hand thats not true. Assuming you have a new 2.3L and not the old one stock it makes 143 HP so half that is 71.5 so about a 70-75 shot. thats a general rule of thumb anyway and may not be true for your truck.

 

whatever it can handle until it blows!!! you said youre swapping the engine anyway right?

 

Sorry about calling nitrous NOS and yes I can be called a racer. I bracket race at Mason Dixon Speedway in Hagerstown M.D. I race a 74 Dodge charger 318 runs 15.02.

I was asking about nitrous on the 2.3 because I want to see how fast I can get the 2.3. Now it runs 20.45 no lie.

The 2.3 only has to last a 1/4 mile. then i'm going to put a 302 in it.

 

yes i am ones it turns historic

 

he said ricer not racer!!

 

oops i read to fast

 

if you use a progressive controller, you should be able to safely spray up to 75bhp safely. (assuming you set it appropriately) what year is your truck? what transmission do you have? thats probably your weak point. if youre going to go with a single-stage wetshot, i'd say stay at a 50 shot or less if you want any longevity out of your engine.

 

its only for 1 quarter mile run, i say hit it 125 and see what she will do it it blows let her blow who cares its getting a new engine anywho

 

well how do you expect him to figure $hit out? afaik, asking questions helps the learning process ;o)

 

I'm getting a new engine. When I do, I want to blow up the old one before putting the new one in. So I just need it to last 1/4 mile so it doesn't blow up untill I get past the finish. It needs blow up right afterwards though. Thanks for the information though.

My truck is an '87 with an AOD transmission.

 

hehe... if you want it to blow afterwards... go for 100-150bhp+. i bet it would be fun to blow an expendable engine for the hell of it. heh.

 

You might damage other stuff in the process. We blew up a subaru Justy in auto class in high school, it shot pistons everywhere. Luckily there's only 3 pistons hahah~

Do you wanna put nitrous on an '87 2.3? Stock? How many miles?

 

In that case a 300 shot should do it but don't hit it until the 60 foot mark.

 

Right now I got 50,000 miles on the engine the truck has 120,000 miles on it. But I got few more year before I’m reedy to put the 302 in.

When I put the 302 in the truck I should get a new Trans and go from a 7.5" to a 9" rear.

 

The old Lima 2.3's are tougher than you think. Try the 150 shot and then check the plugs for lean burn. You may have to seriously richen the mix, but I wouldn't be surprised if the engine survives all that nitrous. I've had a few Ford mechanics tell me about the strength of those old 4 bangers.

 

As much nawz as vin diesel can pick up and throw in your bed!

 

i say since u have a new engine spray a 125.....i spared a 75 and was going to spray a 100 but....u have a back up engine so 125 or 150 **** it man thats what u need to say and do it......have fun

 

I'm going to try a 75 shot then check the plugs, if everything looks good then I'll try a 150 shot and go up 25 until it goes BOOM.
I'll let you all how it goes when I do it.

 

x2. Nitrous (not NAWWWSSSSS) can be very safe, or it can be very disasterous. If you don't know what you're doing, I'd put my money on it being the latter.

 

if you just want to make 1 pass. just say fawk the world and run a direct line to the intake and wire up a valve like you would use on bags.. im sure nothing could go wrong haha.
but my brothers friend put a 100shot on a 4cylinder s10 and had no problems with it.
just run a 150 and call it a day... lol
also. go to a private air port and put a gallon of aircraft fuel in ur tank and then fill it with about 8gallons of pump gas. that alone will make ya crap yourself.... occording to my buddy who did that in his old 78 firebird... ha

 

I understand your goal. Since you hav'nt much to loose you want to "push it" but don't want to be dumb about it.

Remember this.. fuel is what burns and makes the power. Putting too much nitrous in will only make the burn too hot and blow stuff up.

If this is the end for this motor.. put as much fuel into it as you can and spray on top of that.

Up the fuel pressure, new fuel filter, ect.. anything you can do to put more fuel into the motor while spraying will help.

If this is a fixed hit system.. I'd say go with a 75 shot with the rpms up to at least 3000. Throw in a set of cheap plugs that's 1 or 2 ranges colder than stock.

As long as you can feed it the fuel.. you'll have some fun before (if) it lets go.

If this is purely a dry shot.. go with a set of plugs that's two ranges colder than stock and go with a 40-50 shot. (this is a little over the top on a 2.3.. but it'll work for a while)

btw: Let us/me know what fails. Hopefully if the fuel/nitrous ratio is correct you'll swell a piston and it'll sieze in the bore.
