Ok I just got a new civic and I was thinking of the way that air works. Like the best way to increase its flow. I am a computer technician and I know that the flow inside chasi works better if there is more air being pulled out of the case rather then being pushed in.

What my question is, I am going to start with making my car breath easier. Should I go with the intake first or should I go with exhaust? Or should I wait to assemble both on the engine. If my exhaust is not high flow wouldnt I just be pushing air into the engine and not have a place for that air to exit? Also is there certain exhausts that work better with certain intakes? Kinda to compliment each other.

My vehicle is a 2000 Honda Civic DX. Is the bare bones model. Standard tranny. Everything OEM.

 

Turbo with a 2.5'' exhaust.

 

an intake wont add so much air that an exhaust is needed, so an exhaust is unnecessary but it still helps. the bolt ons all add up but its not that impressive of a difference. an intake/throttle body/intake manifold/header/exhaust will net a moderate gain (maybe 15%-20% gain im not sure) but then it starts to get expensive.

but intakes make more gains than exhausts so go with that.

also, go turbo when you can.

 

I was talking to a few people that got helped in this situation. I got told to get new internals before slapping a turbo on there so I dont crack a block. Or just do a b16 swap so I can have more options with bolt ons and what not. A JDM engine is not in my near future since it can cost almost 5000 grand right from the get go.

I wonder if the stock exhaust has enough flow to handle more air? Someone told me to look into getting a high flow cat first. Bah I am just trying to get some info and this place is the only place I can look to. Well that dont have a bunch of **** advertising.

Edit: Thanks for your quick replys guys. I was typing when you replied with the horspower gain and the exhaust answer.

 

1. a stock exhaust can handle the air flow of bolt ons, because it doesnt add up to too much more air. but as i stated, it helps.

2. there is no "need" for internals before you get a turbo, people run stock engines at around 8 psi daily.

3. if youre in california, good luck with high flow cats. they are made to barely pass standards, a brand new OEM cat would probably be the best option.

4. the only engines i know of that cost around 5g's are the k20a (jdm type r) and the 98+ spec b18c (JDM Type R), b16's run around 2-3g's depending on year/condition/blah blah blah.
