That's what I did in my 1.6 automatic on 14x20 slicks. I only had a filter, pump, fpr, and exhaust with 80 shot.
my b13 was a 4 door automatic LE. - dang I miss that car.
It would backfire through the intake all the time because I had to launch at low rpm.
The main problem with the GA after a while - SILICONE CONTENT.
I tuned the nitrous perfect on that car and the other problem is the low, slow as doo-doo side feed injectors on that thing so what I did was drill and tap the end of the rail to a fpr - just an fyi - when you tune via air fuel ratio (which is the best way to tune on a nitrous car because of it's spike in temp) you'll find out fast just how crappy the fuel flow is and how much more fuel you need. I cranked down on the fpr so hard and even with a 600 hp fuel pump on my car wasn't enought so I had to fuel jets for 100 on the fuel side.
with the pump and big jets it allowed me to go back to oe fuel pressure so I didn't have to keep adjusting it every time I wanted to squeeze - and I used to tag the unit nearly every day - hahahaa..
Back to the silicone content.
So I had that thing tuned perfect and one day at palmdale (many moons ago) I dig a huge john force burn out and noticed when creeping to the line it was idling a little rougher. I come out of the hole and it sputtered and died 20 feet off the line.
I still have pics of it - I shattered the number 3 piston from between the 1st and second ring land all the way through the skirt.
and the reason why is because OE manufacturers, in order to have quiet motors run piston material with high silicone content.
once that silicone sees heat it becomes brittle and eventually it let's go - or in my case shattered in the cylinder.
good fun while it lasts though.
