ok guys, i have a 1989 lx, runs strong. i have added full length headers, cool air intake, 70mill throttle body, msd coils, high spark plugs and wires. i fully intend to nitrious my stang, but how much is to much? 130,000 miles on stock internals, how big of a shot, in hp, can i run withOUT damaging piston rings and other enternal parts?let me know, and really if you dont even have n02 on YOUR mustang i dont need you input.

although I dont have nitrous on my mustang I still know about it, my advice for you is some blow the motor with a 50 shot some spray a 200. Bottom line nobody knows if your engine will take it!! I did have a friend who used to spray a 175 on some cheapy speed pro pistons

buy an adjustable kit that has jets from 100-150 = good starter kit and make it a wet kit...I run such on mine and have only used the 100 shot and it is plenty on my 347

alright that about fits what i have heard, as far as start low and work up. i know that wet kit is better all around but i am on stock pistons, rings, crank ,heads...believe me or not my 88 was on a dyno last summer @292hp the only "internal upgrade" i have is a f303 cam. i want to acheive 350hp maybe a little higher on my stock 302 short block. i know it can be done, but im leaning toward a dry kit bc its mainly a budget thing.

I'd start off with a 250 shot and add about 8 degrees of timing if I were you, lol

stockmonster

250 righhhhht. but you got a sharp ride

provided you pull timing out itll handle a 100 shot all day long. keep an eye on the plugs they will let ya know.

wrenchturner, bear with me... ppull it out means slow it down right, im absolutley no mechanic im just handy. but you think 100 even with 130000 on a all stock lower half? oh and yes thats my stang minus the cowl for a mach 1
