hi i have a 99 civic ex i have i/h/e a stage one cam and cam gear with retainers and springs i want to get an intake manifold and throttle body with this. My question is if a skunk2 68 mm throttle body would be too big for this kind of setup and if it would cause me to lose any power. I dont plan to turbo ever i just want a littl e more power. Any help would be appreciated.

 

Probably actually going to lose power with that.

 

seems a bit large for your setup.
Do you plan on boosting?

 

^he said he wasnt going to boost. I agree with Mob, you might lose power, and gas

 

so his next question would be what size should he get?

 

Stock until he gets a bigger cam, port and polish, converter to OBD1, chip the ecu, and a tune. ITB's or Intake manifolds/Throttle bodys should be the last thing on your list. After that maybe a 60-62mm for his D16Y8

 

Here's what I'm wondering though.
If you have your intake bored out to 62mm, and put a 68 mm throttle body, wouldn't you still just be getting the 62mm ammount of air intake?
