ive been doing some searching, on a stock motor with pump fuel, alot of guys are running a 100-125 shot. i am mainly using this at the drag strip. My brother runs it on his race snowmobiles, and can help me install it, but whose kits are you guys using?

thanks

 

You may need a TPI fuel pump....

 

that wouldnt be bad, i had my tank out to put a new one in not to long ago.

 

I used a nitrous works kit, but if you can find another, dont use nitrous works, i really wasnt pleased with it, directions were not that great, and installation didnt go very well.

 

use a NOS tbi truck kit. i had one that worked well and never failed me once. and ive personally run a 150 shot on my LO3 with stock fuel pump. thats about the max id go if that hoping your pump is in tip top shape. 125 would be perfect not too much not too little.

 

I also had to use the truck kit. They should advertise it for truck or car cause the engines are exactly the same either in a truck or car

 

where you guys ordering these kits from summit or jegs? thats where i was thinking of going through, or is there a better place?

 

im going to be putting nitrous on my car i will be using the NOS truck kit, 100 shot at first. It is set up for these engines it actually puts the computer into open loop when the nitrous is engaged giving th evehicle mroe fuel but I do have t ochange my fuel p ump first before i do this.

 

NOS tbi truck kit, that's what I use on mine. I have the EBL controlling when it comes on and off though.

 

thats what i been looking at through summit or jegs? is that where you guys got yours?

 

got mine from ebay, hbut if you go to holleys site, you should be able to find it.

 

When i bought mine i checked out both summit and jegs, summit was a couple dollars more but had free shipping, and jegs was a couplel dollars less, but you had to pay for shipping, so they were both about the same but that was 2 years ago.

 

well im thinking of ordering this kid here? http://store.summitracing.com/partde...5&autoview=sku
what do you guys think of this one. again im not looking for something extreme where i want to spend a whole lot. just a little something for now. where you mounting your bottles?

 

that kits for a tpi

 

nitrous works makes a tbi kit. i think ebay sells those complete kits new. i got mine off a member on here. my bottle either sits between the 2 rear seats or in a backpack on the rear floor below perfect view.

 

I personally didnt like the nitrous works kit, but if other people had better experince with it then me, then go for it

 

well i saw that truck tbi kit one. i might just go with that one. im thining in the middle of the rear seats is going to be best so i can open and bottle when i need it.

 

Do you have any other mods? I found it a lot cheaper to get a carb kit, and then just get the right jets for the TBI fuel pressure. But you have to have upgraded to a carbed intake. I modified/built some brackets for mine, my bottle sits in the back, the blow-off tube runs through the plastic, and out behind the pinch seam for the wheel well. If you modify the brackets right, you can get it all to snug up under there and still close the pull over shade.

 

i dont have anything really done to it now except headers and exhaust and a open element air filter. what did you all have to change to get it to work properly. i just want to see what i can do with this 305 being a tbi.

 

you can do 13's easy with nitrous. what you need for it to work SAFELY and PROPERLY youll need a bottle heater, nitrous pressure gauge, fuel gauge adapter if they still sell those or tap the fuel lines with compression fittings or something, colder spark plugs, and 100-125 shot stock timing is fine as long as the chip is stock. youll need to test your fuel pressure to see what jets youre going to need. and between the rear seats is your best bet if you dont run a nitrous pressure gauge to a pillar pod or somewhere which i didnt want nitrous lines running everywhere. that way you can open and close it whenever and you can watch the pressure as long as you set the gauge up either one on the bottle valve neck if theres a spot or right after the bottle nut like mine on a fitting which youll also need.

 

well the bottle heater depends on if you have a wet or dry system. i am going to get the kit that includes it all. do you guys prefer NOS or nitrous works systems? im not trying to get a bashing between the two i just want to know what your results were. also are any of you running a purge?

 

no the bottle heater is recommended no matter which kit you get. plus you wont be running a dry shot on a tbi anytime soon if you wanna keep the motor. so yes you will need a bottle heater. as for the kit i have the NOS kit which works perfect and within 2 years hadnt failed me. and yes i also have a purge but it is dynotune. makes easy work of clearing out the lines after youre all done. didnt really make a difference purging before a race to me.
