I'm desperate...
 

my car is very very slow. i understand that. it is a 94 automatic 4dr civic, with a D15B8. I am looking to make it a little quicker (not that I want it to break 10's or anything retarded), it is just way to slow as it is. Only mods are generic CAI and axle-back exhaust. I am thinking about getting a 50-75 shot of N20 (Zex). Would the DX be able to handle that? (and still drive away in one piece). Thanks, I appreaciate any advice/help.

Just swap it.

sell it and buy an ex or swap it. and its n2o

my bad.... N20

You're definitely going to kill the transmission and blow the motor running that much n2O.

Swap...

ive heard of ppl running 50 shots no problem but i am not sure about a 75 shot.. not on a stock motor dont think so..

Your going to spend roughly 700 cdn on a Zex kit?? Man just save another G or so and swap :) Stay N/A and you'll have your grocery getter and a little power to boot. IMO that is :)

WHAT?! D15B8?!?!?! In a 4-door? What car did Honda ever build with that setup? That's a 70 hp (on a good day) 1.5L CX motor. Dude. I have a spare one. If you have access to another transmission, you should mount this in your trunk and give the engine up front a little push.

Seriously, get that thing out of there. If that engine code is right, it won't even hold n2o. Put a different motor in that thing. D16Z, D16y, hell even a D15B7 would be an improvement. Check that engine code again because I think that motor's only supposed to come in 2080 lb hatchbacks.

Did you top out at 140? I think you need NOZZZZ.

Just swap it. You can even get a gsr auto if you felt so inclined. Or you could convert it to manual.
