I recently picked up an old 93 lt1 firebird and I want to spray it. What should I do to make it semi - reliable ? I was thinking about spraying a 100 shot but I am open to suggestions. Does anyone think this motor is to old and tired for spray?


1993 Formula Firebird a4
lt1 350 with 127k miles.
Oil pressure at Idle 30-35 when hot
Mods- Long tubes, ORY, Flowmaster

I am a nitrous newb so any help is appreciated.

I have an LT1 with 126k and im spraying with no problem so far. I bought nitro dave's plate kit which comes with everything you need to have a safe kit. It comes with fuel pressure safety switch, window switch, bottle heater, all lines, solenoids etc, bottle, purge, filter, blow down tube, and the correct plugs. I also bought an msd digital 6 box to retard timing. This is not a must though, but never a bad idea. Also your stock fuel pump will probably not live long with nos so buy a racetronix one. Hope this helps

you will also need a bigger tb to accept the plate

It will do fine on a 100 shot poeple are spraying with many more miles than that on there car. Hell if it's just your play car put a 175 on it and have some fun. Just put all the saftey equipment/upgrades to run it.

Yes they dohave 2 different size plates, both of which are bigger than your stock throttle body.

Both plates will work with the stock throttle body. I have the 52mm plate with a stock tb. The plate kit with 150 shot took 2 seconds off my et and 14mph

I think I will spray a 100 shot at first to see how it does. If it blows up, its only going to be rebuilt bigger and better so what the hell right ?

It should hold a 100shot all day long you will be bumping up to 150 before you know it just do a fuel pump and spray it!

Your Lt1 should be fine on the bottle, of course it does depend on the condition of the internal organs since N2O does put more stress on the rotating assembly. I have seen motors with more mileage on them than yours last on the spray and i have seen motors with 1/3 the amount get destroyed.......
My 6spd Z in avitar was a consistant 14.1- 14.2 yeah vegas heat sux! 2.5" y-pipe no cats welfare cai no tune and worn out DRs 12.26 @ 115 on a 150 shot.now i am full bolt on and gonna use a 150 shot again in Oct

You'll be just fine with a 100 shot. I would look into a Mallory 685 box though. Window switch, timing retarder, and two step built in. Taking out timing is always a safe thing to do and keep the motor from detonating.

If you got the Nitro Daves kit you got a good quality kit. I would not be worried at all about putting a 100 shot through that plate on a 126K mile LT1. Just don't get greedy, that's when stuff will start breaking.
