I have been thinking about spraying since i have only a 305 thats all stock and don't have the money for a 350 or anything. so my questions are:

the stock 305 how much of a shot do you think it could handle 100 i hope easily. I would go with a wetshot just because it seems easier, will i need a bigger fuel pump. i am not sure if the fuel pressure gets raise or if the pump itself just can supply the fuel. i could go on into detail of questions but i'll leave it to the pros.

can my drivetrain handle this being all stock and what kind of times could i expect on average?

i have delt with turbo's alot so i am not in the dark on everything.

 

Is this a new motor ? If it's old I wouldn't toss the 100 on it . Your driveline will not last long with it. But remeber to retard timeing and all that preventitive stuff. Buy every safety switch you can ( like , fuel preasure drop , etc)

 

its a new motor, just has only about 8k miles on new motor. what all do i need to get to setup a wet system on my car?

 

I am a turbo newbie and just did my first boosted car. I wouldn't even bother with the nitrous if you know about turbos. No bottle to fill.....just run it.

 

yah but the thing with n/a cars modified to be turbo cars they are not always super reliable, and get worse gas milage then before with the juice i get decent gas milage and when i want to go fast i flip some switches

 

Reliable? Sounds like a few bad turbo setups. If you do it right then it will be just as reliable. I have driven some turbo trucks with over 300K miles with a stock non-reman turbo. All never had downtime due to the turbo. If you drive a turbo vehicle like a N/A vehicle then the gas mileage is the same. At least with my setup it was.
I think you already have your mind set on nitrous. A little searching showed 100-150HP. Few switches? Are you going with an electronic bottle opener?
