Im interested in spraying a 50 shot on my car. i have stock internals, what corresponding mods do i need to do this? Is a 50 shot too much, give me the details guys. Ive got a 12 second t/a thats pissing me off, i just ran a 13.3 in almost 90 degree weather so i think i can do 12's on spray

 

I was running a 50 shot of dry nitrous into a stock 2.5L '91 Dodge Daytona Engine. That thing was SOLID. So i'm betting that a WRX engin would be able to handle it no problem. Also depends on duration, i wouldn't let it run from WOT at launch until finish, then i think you'd be ruinning insto some trouble.

Although you have stock internals do you have any other mods? Just curious

 

duration smuration...if installed and managed correctly you can run nitrous through an engine till the bottle runs out...i have a 98 impreza L with a NOS wet kit and ive run through all but fifth gear on a 50 shot and i do it alot....heh...nitrous has a bad rep for killing engines, but its usualy not the nitrous that kills it, its lack of fuel...
i have however upgraded my ignition and changed the plugs, which you prolly wont have to do since youre runnin 13's already

 

If you do go ahead with NOS make sure to do some research, buy a catless uppipe and an egt gauge.
