DIY How To Instal N2O Part 2 Corolla 98 - 02

[KING7thGen]

Finally - after many many hours spent in the garage - my baby is officially on the bottle :fu:

and now the pictures:

Engine bay looking empty with no battery and no CAI (yes that's pink saran wrap protecting the TB so back the fuck up off me lol its all i could find)


bottle with its new NOS high-flow valve and Zex pressure gauge lol mixup


AEM CAI + Drill bit + NOS Dry nozzle =


what my throttle body would see if it had eyes


removing stock spark plugs to replace with colder range Zex plugs:


everything all hooked up:


my A/F ratio gauge (not installed yet - just hooked up to power for picture purposes - it's black when not on and ya can't see shit then:


finished product with wires tucked away and engine cover back on:


And now - the writeup lol

Well, we had some issues in the testing phase. Apparently when we took the left-front wheel off to remove the CAI, I didn't put the lug nuts back on properly - car shook like a mofo bout 2 miles from home. Went back (without spray yet) and realized we had lost a damn lug nut. Argh. Put stock steelie on back wheel and rape back wheel lug nuts for front wheel that is nut-deficient. That's better.

Out on 417 - open the bottle, flip the switch, get goin a bit in 2nd and floor it. Nothing noticeable in 2nd. Pulls really nice in 3rd. That's about it. Feels about .2-.5 sec quicker MAYBE. Stop on the side and run from a stop. Feels stock in 1st which is surprising. 2nd pulls a bit more. Again 3rd is teh winnar. Still disappointed. Consult friends online and get reminded that the 650psi my bottle is sitting at is quite low and optimum n2o bottle pressure is 900-1100psi. Low pressure = less power. Will be consulting the guy who filled it tomorrow. Until then... that is all.

So after several attempts to go out on 417 and see what she can do with her new-found ponies, I've come to a few possible conclusions:

1) n2o is highly overrated (i doubt this)

2) low bottle pressure is causing the less-than-impressive gains (quite possible)

3) a "50 shot" really gives nowhere near 50hp (see #2)

Ummm yeah he had low bottle pressure that makes a big difference my boy was running a 50 shot on his 9th gen with full bolt ons and no tune and he was beating si's and rsx's with bolt ons then he went 75 shot and was beating full bolt on tuned k pro 05 rsx's which if you know anything about k20z1's they are the best Usdm K you can get and put respectable numbers down
