whats up, im new in this "world", so i really dont know too much, except for a friend i have that tought me almost everything i know about tunning. Anyway, the bottom line is that i know that the D17 is not really as good as D16 or another engines (for modifications i mean), not even giving the example of a K20 (which i would love to have), but what i want to know is if i decide to put some money on it, what would be you guys do to a D17a2? mmm... i know that all of you would prefer an engine swap, but first i dont have the money, and second im not willing to have anywhere near 300 whp (too expensive, and its a daily driving car). I just want something faster (definitely) than 127. Whatever you guys tell me, will work for me to learn more about this. By the way, i have an '05 EX. Ill post some pictures later. The only modifications it has are springs and 17" rims. It is the first time i do something to one of my cars and i loved it, so i want to get little by little a little bit more into it, starting with a short ram and full coilovers if i keep the D17. Anyway, ill wait for your answers. Thank you very much

An intake and exhaust are really the only things worth spending money on IMO. You get a little extra WHP, along with some sound and that is about it. I would not go any farther than that.

Suspension on the EM2 is my first priority, as I am planning on a K swap before too long. Build it up. It is pretty much the only parts available for our cars, and that actually produce results.

What are your goals with the car? What do you want to do with it?

 

Well, the goals are to have a relatively fast car, besides just the looks. I already have the exhaust by the way, so it sounds pretty good.

I dont think i want to race it... at least not for now, but i want to be able to keep up with other cars with around 200 whp for example, or anywhere around that. Putting a turbo in a D17 is a waste of money?

Depends. Do you want to spend 5,000 bucks to get that 200 WHP and for the most part, be maxed out? Or do you want to spend 5k on a K-series swap and START with 200hp?

It is all on just what you have your mind set on, and your goals with the car.

200whp on the d17a2 isn't that hard to acheive, but you have so many things going against you on this motor, it is ridiculous.

 

obviously you get the point. I just didnt know that a turbo will cost me 5k, i thought that 3k would've been enough... but you might be right. By the way, i read the whole thread about the K20 swap and the prices were from 6/7k min, to roughly 10k. You think i might get the engine + instalation for 5k? If that is a yes, I'll start saving some money...

 

well the dezod v3 kit is only 3,200 but needs a fuel and engine management system which ball park mabey 1000. The kit itself though i heard gets good gains

 

gotcha, so basically rather than the exhaust, air intake and suspension i shouldn't spend anymore money on it. Just save for the K20 engine swap. Alright, thanks for the opinions. if anybody else have something to say, i'll be looking forward to more opinions.

Thank you guys

 

Ditching the heavy 17" rims (unless you have forged wheels) and getting a set of lightweight 16" or 15" rims will add more noticable acceleration than an intake will.

Trust me on this.

 

you could build your own turbo kit as some have... if you check on 7thgencivic.com they go for like 1500-2000

not a really reliable setup, most install it and turn around and sell it within a couple of months because its a pain. but if done right, it's a decent mod.

i'd say you're good with 4-5psi. you'll catch up pretty quick to a stock type s.

 

im actually thinking about going to a 16inch rim from my 17inch rim will my car gain power from that? lol that would be like a bonus.

 

Yes your car should gain some power. Keep this in mind the bigger the wheel the more hp lost because your engine has to rotate a larger mass. As Todd00 said a lightweight wheel or smaller rim size with add noticable acceleration and mabey a few hp.

 

you won't gain horsepower by adding wheels lol. but you'll notice better acceleration due to a smaller diameter wheel and less weight.

 

I know for a fact that you will lose hp by putting on a bigger wheel a loss of mabey 2-3 hp whats to say that it can't be reversed using a smaller wheel?

 

you can also gain 10-15 hp if you swap you valve cover...

 

sarcasm doesnt help the subject if you have nothing to add then don't say anything. really though think about it going up in tire diameter is like gearing up (higher gears) smaller diameter is like gearing down lower gears, higher numerical value

 

lighten up....i had to say something so i said it.

its simple physics. obviosly its going to take the engine more power to rotate a bigger mass. meaning the car will move slower....

by the way your comment was just as useless as my sarcasm
wait let me really think about the tire diameter........nah.

valve cover swap

 

see by you replying to me the way you did made me think that your saying that its B.S and doesnt happen so i tried to explain myself better thats all if you wanna do a valve cover swap and gain 15hp thats up to you i rather just put a big *** wing on and gain 20+

yes downforce is required.

wing+ valve cover = one bad *** honda!!! ****! no need for k-swap after that....

are you serious?

 

yea i was reading a honda acura book and these guys were building up a crx for a track. They upgraded the originally steelies to i believe 18 in. rims and did a dyno before and after and it showed a loss of hp after they put rims on. I was going to upgrade to bigger wheels at that time but figured i'd just keep my 16" honda alloys

 

the motor isn't making any more power.

only thing that is happening is that with heavier wheels, its harder and more sluggish to put that power to the ground, thats why a dyno would read different numbers.

 

i say do nothing to it. its a very powerful motor. when strapped onto a 500lb gocart.

 

i'd love to see taht done

 

A dyno measures power that the car puts to the ground (real-world HP numbers). While adding pulleys and lightweight forged wheels does not increase the power the motor makes, it does increase the efficiency of the motor.

People who worry about adding an intake when they are running 22lb 18" wheels really crack me up. Adding a 3hp intake might decrease 1/4 times by .1 or so, reducing 10 lbs of wheel weight mass per corner might decrease 1/4 times by over a half second.

 

my friends and i were actually toying around with that idea if i were to get a swap haha.
