i have a 98 civic ex coupe with a 1.6 liter sohc vtec and i was wondering if i got a performance cam ( killer) with new cam gears what else would i have to upgrade along with it?

 

springs for sure and some valves if u have the cash. how muh power are u trying to pick up?

 

Searching is your friend. And it sounds like you have a lot of that to do. But I will help you out to the best of my ability.

First off, get this "killer" term out of your head. The word "killer" associated with the word "camshaft" comes from a company called Toda Racing. They manufacture a camshaft called a "VTEC killer", which eliminates VTEC within your motor and makes power by having a very high lift duration, which isn't recommend at all for daily driving. The company only makes that camshaft for the DOHC VTEC engines and not a SOHC.

There is however lots of companies that make a good camshaft for your engine. Start searching into Skunk2, BC, Bisimoto, Comp Cams, etc.

Upgrading your valve train depends on the type of camshaft you get. For example, a
"stage one" camshaft could be used with the stock valve train because it still maintains good idle, and is usually designed to make power within the engines factory redline.

Going with a "stage three" camshaft or something however requires a lot more work. You will need to completely upgrade your valve train with stronger valves, retainers, springs, and a port and polish is recommend to take advantage of the new higher flow. This camshaft will be designed to make more power at or past your redline which essentially is why you need all those upgrades, to prevent things like valve float.

Lastly, DO NOT forget a tune. An upgraded camshaft without one is USELESS. You are adding more air into the engine, and this means you must add more fuel (in basic terms).

Good luck.

 

yea he basically explained everything you need to know at this point just keep researching and reading reviews on the ones your intrested in
