Best things i can Do to improve power....without a swap??? Options

[KB-2]

okay.
so im looking to just make it slightly quicker
i know of an intake......adn thats about all i know

anything else cheap that willl do anything?

A good, quality nitrous setup is perfect for somone who wants power on a budget. I think ZEX makes a nice dry kit for like $450, which isn't bad at all.

everyone alwasy says that, but i have never seen a nitrous setup of a 4cyl econo motor last more then a few months of joy rides. a dry kit would definelty lead to engine damage, imho.

Actually I know quite a few people who have had great success with them. I had one '92 Corolla with a 4AFE in my shop a while back, he had been running a ZEX dry kit for like two years when he blew the auto tranny. After getting a swap, he sold the engine and it's running on another car to this day (as far as I know). As mentioned, it's important to follow the ZEX instructions, which say to use colder spark plugs and retard the timing. This is very important.

Also many people, obviously including you, don't understand how a dry kit works. They think that it injects N20 without compensating with fuel at all. However, that's not correct. A dry kit add fuel by increasing the fuel pressure when the N20 is being injected. A wet kit, which taps into your fuel system and injects fuel into the intake with the N20, should NEVER be used on an EFI car. The reason is that the intake manifold on an EFI car is designed to flow ONLY air, which has different flow properties than fuel. Using a wet kit on a car with and EFI-designed intake manifold will result in one cylinder being very rich and another being very lean. That type of kit is for carburated vehicles. However, a dry kit is only safe to a certain level, usually a 50-shot on a 4-cylinder engine. Beyond that, you would want to go with a direct-port kit which injects both N20 AND fuel at the PORT LEVEL, so each cylinder gets the right mixture. That's the best, and most expensive, setup that you can buy.

Also you can tune N20 injection with some piggybacks and most standalones, which is even more ideal.
