What Are The Weak Points To The Honda Civic Si Engine That Could Be Replaced For More Hp?

5 Comments 25 September 2009

I’m fairly new to tuning cars, and I’d really like to get some nice performance out of my car, my goal is to get a Turbo in there. So are there any other upgrades I could do and if so what specifically?

    nitro,suspension,cold air intake,turbo,flowmasters exhaust this setup will give you some horsepower but not a lot if you want a car with some power just get a 1971 chevelle ss a put a 454 in and work on that you will get a lot of horsepower and way faster than any honda

    the number one thing you can do is research, dont accept shitty sales ppl’s advice about your car, bc its your car. if you are looking for stuff to do under 500 then you could start with intakes depending on what model you have different intakes will work better, i have an AEM v2 on my car because it provides the most ammount of hp, so basically disregard price if youre going to try to do it right, bc to mod your car right you have to spend a little extra. also you could try a full exhaust, but its really not going to do anything and theres really no reason for it unless you have forced induction or alot of exhaust. another thing you could to id the intake manifold, usually they are engineered to find a nice middle ground between performance and fuel efficiency, you could get a straight performance manifold, and increase a decent amount of hp. and lastly, if gas mileage doesnt matter too much you could throw in a different cam shaft preferably a stage 3 bc there is really no reason for a stage 2 or 1 if youre eventually gonna get a 3…also v-tec controllers are nice, standalone systems are nice, but really pricey, and turbos are wonderful but you have to do your research, or you could always pay someone else to, and if thats the case, id be more than happy to help… :)

    short of nitrous and turbo, there isnt much u can do to up the performance. i got a book on it and it is pretty much at peak. u can change the intake to a cold air, better exhaust manifold etc. maybe a bigger throttle body.

    if vtec engine get a vtec controller, i would recomend from Apexi V-AFC looks cool and its works…intake&the exhaust.. then get a fuel regulator from SARD, and finally a turbo kit .. (costly a bit)..
