the civic vtec already comes more powerful than other civics...but are there parts u can add to the vtec to give it more power/horsepower? and if so, wat parts?

well no not really. the car was already tuned very nicely at the factory. unless you build the engine up inside with port and polish head, valve job, new camshaft, and cam gear plus tuning on the dyno, there isnt much you can do easily.

dpras37

why does it have only 197 hp then?

gearbox

iTrader: (95)

its only a 4 cylinder engine with small displacement

dpras37

would u say its a good car when it comes to speed?

gearbox

iTrader: (95)

its not bad, but i wouldnt like it. most of the power doesnt come in til 6k rpms. below that, feels like regular civic.

Krieger

wait.... what???

wtf is this civic vtec? is that a car?

or are u asking if u can upgrade the vtec on ur car that u have already?

i think hes talking about civic SI, and how to improve the vtec/

dpras37

yes, thats what im talking about

Turbo it and then stop complaining

dpras37

im not complaining, if u havent gotten it yet im new.... so thats why im asking these questions

well if you dont have much money, do the usual bolton mods like intake and exhaust, etc. i would check 8thcivic.com for brands and reviews cause they deal alot more in 06+ civics. we are mostly 01-05 here.

dpras37

oh ok, because i dont have a civic yet but i plan on buying a '99 civic si...

amishman22

oh well in that case you're gonna wanna look on the 6th gen. but 197 horse is quite a bit for a 4 cylinder. he's right the easiest way to go is exhaust and intake. past that its much harder and more expensive with stuff like turbo(a couple grand) or cams(600+ and tuning). do the bolt ons and enjoy.

dpras37

oh okay thanks, u kno i always thought that the exhaust was only for design...is it the exhaust tip itself that adds to the car's performance?

amishman22

hahaha. no. beginners mistake. the performance comes from both the headers which allow better air flow from the engine to the tail pipe which is wider and much more efficient than the stock one. the tip is mostly for looks/sound.

dpras37

ok so the bigger the tail pipe, the more fumes can leave the car at the same time

amishman22

yeah something along those lines. and it all depends on who makes it because of the shape of the exhaust can affect performance.

dpras37

so roughly how much money are you talking when u talk ab out the bolt ons?

spartigoose

yoooooo

99 civic is a whole different ballgame. there are TONS of parts all over and ive seen built engines (no turbo) easily make over 200whp. superchargers are dime a dozen and also boost performance quite a bit, ive seen one around 225whp with just a supercharger and few other mods. thats pretty much the best moddable honda engine.

amishman22

pipes are usually around 500 but look around i got mine for 440. headers are 220-340 again look around i got mine for 240. and then u might need a cat(prolly 200).

dpras37

oh ok, so the 99 si's horsepwr can increase then. alright, also can anyone tell me the difference between a turbo and a cold-air intake? sorry again, im new

gearbox

iTrader: (95)

cold air intake is just a pipe and filter that replaces the factory air box and filter. gains maybe 5hp. turbo is an actual metal turbine that attaches to the exhaust manifold and spins from exhaust blowing through it. the air then goes through an intercooler usually in the front of the air to cool the air down before it goes in the engine. basically it forces alot more air into the engine than it would ever suck in by itself. and when you have a ton more air, you need a new engine computer and some dyno time to tune the fuel so you are getting the proper ratio of air to fuel mix. can give 100hp+

dpras37

oh ok, and are both of those applicable to the 99 si?

gearbox

iTrader: (95)

ya you just gotta check around different websites and some tuner shops around your area. there are alot of parts for that year car.

amishman22

be careful tho. the intake is cheap and less hp but when u get a turbo your lookin in the 1000's with price, parts and tuning.

I-EAT_RICE

Oh yeah, you can get 40HP easy out of a new exhaust tip. And dont forget to add lotts and lotts of stickers. Them babys are atleast another 10HP EACH!

Krieger

you know, he might take you seriously...

he is vry new and all.

but ya, get a nice short ram intake, and a cat back exhaust and ur set. a header only helps when ur going full tilt boogy... otherwise it robs ur low end like no tomorrow.

dpras37

ok straight thanks for your help everyone!
