Hey guys, I'm a new civic owner (2005 value package) and I'm wondering what I can do to squeeze the most HP out of my engine, and what possibly is the highest HP possible with this engine?

I'm looking to put in cams, heads, exhaust, intake, valves, turbo, nitrous, whatever it takes.

Thanks in advance.

you could make it as high as you want as long as you have the money for it. for the right amount i would say 250+

start with pnp head work, valves, cam, retainers, cam gear, i/h/e, but keep in mind you have to build it for what you want either na or turbo. A bolton turbo kit will net around 150whp (stock is below 100) but might not last very long.

Well, if a turbo is gonna tear up my engine that badly I probably won't put it on. How much HP do you think I could squeeze out, with just parts if I stayed normally aspirated?

^ why would it not last very long?

....swap to an ex engine.

head swap to ex engine. turbo it with pulleys i/h/e lsd and aem plug + play. around 200hp. then nitros with 50 or 75 shot. 250-275. all the stuff gearbox said would help bump the hp to 300. all together 300+

As in the original message, I meant horsepower out of this engine right now, not a new engine.... how much can I get out of a normally aspirated D17A1?

 
Rep Power: 336

200 all motor. maybe 250. it would be expensive

How expensive are we talking for 200 horses? I'd be content for life if i could get 200 horses out of this car.

the highest any member has reached na was around 140whp. civic ex, pnp head, valve job, i/h/e, hi flow cat, cam gear, vafcII all tuned on the dyno. I can't imagine even coming close to 200whp na. there's no way.

 
Rep Power: 336

ok nevermind then. i thought if you get cams and valves and high compression pistons it would help alot.

....140 to the wheels wouldn't be slow man.

ex convo. shouldn't be too much;

as of now, I dont think any D17 is up to the 300WHP or 300BHP mark... thats unheard of..... By that time, some sort of reinforced tranny would be needed. The best choice here is a K20A2 swap... sorry, D series is just an engine meant for high MPG, not much power, and long lasting.

300 has been reached on a d17 I forget if it was to the wheels or bhp

it was whp at 18psi

the tranny limits our motors.....anything over 250whp is asking for trouble with the tranny.

 
Rep Power: 811

i think it was 300 whp from SF power.

 
Rep Power: 0

yup, you guys know whats up. It can be done, but the tranny is the major problem. Nothing for them yet. Cryo treat the tranny is about the only way right now isnt it? I could be wrong, havent been online as much the last month or two. could be new parts?

i will have 180 are so

Catalyst never posted dyno sheets

Barney made over 300whp

 
Rep Power: 338

wow, I stand corrected. Built motor?

How easily could I reach 150-200? If I could get 200 out of this D17A1 without turbo or nitrous, I'd be 100% satisfied. Actually I'd be satisfied with 170ish, but 200 would be PERFECT.

 
Rep Power: 336

dude, any motor can be meant for anything. as long as you have moola its all good. anyways, k20 is overdone and im not saying uneffective but way over done. id rather take the road less taken and build the hp. more respect that way. and a 250 hp 2500 pound car sounds fast as all hell to me. lol.

btw whoever repped me, thanx

if your planning to swap, youll definately love the rsx-s complete swap (k20a2). if money isnt an issue that is (which im assuming isnt since it sounds like your willing to cash yourself out on this civic). but of course, itd defeat the purpose of buying the "new" civic.

i think your best bet of getting high hp numbers is the turbo route. sorry to say, i dont think there is any way your going to get 200hp going n/a...

 
Rep Power: 607

150 is reachable but 200 is way out of reach unless you have major money. I have never seen a 200whp n/a streetable sohc motor.

Is there any way to turn this motor into a DOHC? Or would that require a lot of rebuilding to have two cams?

Can anyone list me some parts that I'd need to get 150 out of this engine NORMALLY ASPIRATED. Exhaust, cams, whatever I need, just list them for me and maybe where I can find them for 150horsepower, and I'd be ever so grateful. Thanks.

I have a 2004 VP. I made 111whp with I/H/E crank pulley, and no power steering belt. Not much to brag about. A little weight reduction and some practice can get you into the 15's easily, but still aint ****. N20 is the cheapest way to make a D17 faster. Dowside is you can only use it for short intermitent runs. At the same time you are not constantly stressing your motor. Like I said as far as straight line and 1/4 mile performance N20 will net you the biggest hp gain per $$$. All motor D17A1 will cost probally as much as a turbo and you might make 150hp if your lucky. K20 is bad *** but lots of money $$$$. Could buy 10 D17s and run a 75 shot on each of them till they blow for the same price. It all comes down to money and preference. If you got the money you can make anything happen.

I can't afford the price of ruining my car to put nitrous in it. I really need to find someone who can help me work with the tranmissions. I have the 5spd manual deal, but for first gear, I can barely get to 10 or 15mph before it starts to sound like the engine's gonna blow, so basically I just don't even use 1st gear, I just take off from 2nd. Are there any modifications I can make to the clutch or shifter, or the gear ratio's to make my takeoff speed more efficient, as is right now?
