ok, i tried to seach but got frustrated with all the turbo vs nitrous bashing...now on to bigger and better things....
i want to know what can be done to a stock b18a1 ls motor as fas as nitrous is concerned...i know about proper tuning for better response and overall delivery, but if i decide to run high compression will it be good or bad, and if rumor is correct and an ls can hold 14psi of boost on stock internals, what would be the highest shot of nitrous that a stock ls handle with i/e without engine management...?
im gonna start around a 50 shot and tune my way up, where will i safely top out?....thanks and sorry for the 68 and a half part question.....any help is appreciated...

 

14 psi on stock internals is not the greatest idea for one, BUT, LS motors do respond well to nitrous... If you can keep a safe air fuel ratio across the board you should be able to spray a decent shot... I have seen stock LS bottom ends hold a 120 shot, but I wouldnt reccomend anything more than about 80... To do this safely you must run a wet shot and upgrade your fuel pump... theres nothing worse than having good a/f ratios on a dyno then going out to a different climate/environment and having everything go haywire... Also, slightly retard the timing via the distributor or invest in a jacobs nitrous controller.... from there you can slowly work up and with constant care, maintenance, and tuning, i don't see why a 100 shot would be a problem.... Just make sure to check everything over and make sure everything tuning wise is on the money before you go to crazy...

Also, I do NOT reccomend higher compression with nitrous as this will further increase horsepower and test the limits of the internals of your motor... This also goes for high mileage motors that have developed a carbon build up on the pistons that can cause compression to be raised...
I am by no means a nitrous expert, and with that being said, I say find someone who works with it on a regular basis and has that experience to tell you if anything I said was inaccurate....

Hope that helps some....

 

We ran a 65 shot on my friends teg and switching over to boost.To me it wasnt fast but it ran a 15.7 spinnin like a mofo.

 

The question at hand here Mr.Cronic, is Nawwwwzzzzzz....

 

75 dry 120 wet, but if you do high compresstion with stock internals i woundnt go more than a 65 wet shot , with high compresstion its not going to be easy to tune

 

they go very well together, but he will be testen his stock botton end ,with tuning with high compresstion it takes alot less timing and more fule, if i was you i would get a msd that takes timeing out when you hit the n20 so you dont lose any na power, i would use stock plugs ,i would also built the head the stock ls heads are weak and if you drop a vavle you will be buying a new motor,i ran 10.5-1 compresstion with a 225 shot on my gsr
