Honda civic Si

**vuvu** · 16-12-2003 05:27 AM

Hey guys
my dad just bought me an eh9 civic si sedan.. the one with the d16a8 engine in it
so far it goes pretty good.. didn't expect it to be quite that quick but i've beaten an MR lancer (close race) and chopped a CA18DE Exa lol.. funni shit
just wondering wat mods will increase power? a 2 and a 1/4 inch will increase power by how much? Cold air induction how much? how much power would i gain and how much would it cost?
just want rough estimates as i really know shit all about non vtec hondas
any help would be appreciated
Thanks

there have been limitless threads regarding induction systems and exhaust systems... might want to have a look at them as well for a bit of a reference. 2-2 1/4" size is good for the civic - anything larger and you'll be losing power.... you could go for the whole exhaust system or just replace up to the catback.... depending on your budget - obviously the whole exhaust system will give you a bit more power but more $$... it is hard to say exactly how much gain these mods will give you, but the car will definatly be more responsive on throttle.

Like all NA Honda’s
Your best bang for bucks is a lightweight flywheel.
CAI & headers help a little too...

If you've got the budget... B16A engine swap...

why do u lose power if you get a bigger exhaust?

**vuvu** · 17-12-2003 10:01 PM

not enough back pressure i guess...

yeah i can get a b16a engine for relatively cheap... but how much fabrication is required? heard for a mechanic to do it will cost 2k +

so 2-2 1/4 inch is good yeh? approx price?
thanks
