What are some low cost options for more HP in a 91 accord aside frome cold air and high flow addons?

underdrive pulleys ( smaller pulleys) exhaust get rid of stock muffler better plugs and thicker wires

Cams/chips make a good amount of hp for little money, but you have to run 91+ octane with a chip.

You can get a chip and do some port and polishing to the heads,Also get a light weight fly wheel and smaller drive pulleys,Maybe an MSD box and racing ignition wires!

I would try a header It ads i think like 60 to 70 hp to you car.I got a 4,2,1 header for mine for $60.00 on E-bayO ya turbos are a good way to go to.

dude **** the exhaust, that'll only increase whp by like 1 or 2 depending on engine size and pipe size, camshafts, camgears, pullys, pistons, anything done to maximize efficiency of the engine will increase whp, a turbo is ultimately the best option and usually the cheapest whp to $ ratio. but you also have to look at the car...a 91 accord wasnt that great for modding, and if youre trying to make it run 12 at the track, low cost isnt an option, my advice is the turbo or an engine swap. both of which are costly.

Cheapest whp to $ ratio would actually be a nitrous oxide setup. You can pick up a dry kit and run a small jet, say a 35 shot, which would be safe and give you about a true 35 whp. You can pick up a used kit by Zex, for example, for about $300. It can be installed in an hour, and easily removed in the future. A 35 shot wouldn't even really require you to run colder spark plugs. Definitely the best bang for your buck, seeing how it would be cheaper than a full exhaust and net about 25-30 more whp.
