Do you guys think 170 HP is possible out of the 1.7 VTEC engine? I'm thinking ported and polished heads, divverent cam, pistons, whatever. Is it possible without forced inductrion or nitrous?

IMO, no. i'll buy you a [IMG]i/expressions/beer_yum.gif[/IMG] if you can prove me wrong [IMG]i/expressions/face-icon-small-cool.gif[/IMG]

I think so. The keyword being stroker. [IMG]i/expressions/face-icon-small-smile.gif[/IMG] Anything else is chump change.

Anything is possible to a certain extent. It's all about the money. Heck, you could throw a jet engine in there if your wallet is big enough. [IMG]i/expressions/face-icon-small-smile.gif[/IMG]

I think it's feasible, with a turbo, and EVERYTHING ELSE available for the D block. . . but anything less than that and things are a little less feasible. . .

yes. it is very possible.

JoeB16

its also possible that i can shoot a gerbal 100 yards if i stick it in an APEX-i dunk muffler and start the car.

The motor got screwed when it came to HP but to hit 170 is definetly possible.

Venom Intake Man.
Honed TB
Different cam
lighter fly wheel
CAI Intake
Get more air to the motor (intake man. intake system TB) boost the injector size up 4-7 lbs

The colder the engine the better the HP
B&M Oil Cooler
Different Water pump
Thermostat

I know that with the proper knowledge you could make 170 fwhp N/A

JoeB16

those mods you mentioned arnt going to get you anywhere near 170 WHP.

ZRPM

I'm talking Crank HP, not WHP. I think WHP is a real stretch. Bu given enough $$, I think it may be possible to massage 170 Crank HP out of the 1.7.

Turbo, Nitrous or Supercharger may be cheaper, but I like the thought of a N/A 100 HP/liter Engine.... Wish they had just dropped B16's into these rather than developing a new, less powerful engine....

About how much more HP in gains can we get from Port, Polish & decked. I heard a friend of mine say a good 8hp, which I think is a lil low for about $800 job. What you think. We can we get more gain, besides turbo, superchargers pockets are kinda emtpy from doing body work and paint.

JoeB16

FWHP = Front Wheel Horse Power. Emphasis on the WHEEL part. No, you didnt say "crank" hp.

And a port and polish isnt going to get you anywhere near what forced induction, N20 or an increase in displacement will get you. I can see 8 WHP out of it on an otherwise stock 1.7 tho.

I agree with JoeB16. Also, take note that though a p&p provides only a small amount of hp, it increases the potential hp increases for your engine with things such as i/h/e.

JoeB16

or more important things that would take advantage of a PnP engine like FORCED INDUCTIOn, NITROUS, and/or an INCREASE IN DISPLACEMENT.

It sucks when you want to go fast, but already spent all your cash on useless things like body kits and odd paint schemes huh?

joeb16 is right. im not really goign to feel any big power gains until i do FI or nitrous. yes there is more power but not enough to let me stay in a race with joeb16

well it would be possible if you got a accord, my old one had 160 stock '99 accord sedan 5speed

No he's not. Maybe he didn't understand what I meant by stroker? A stroker engine is one that has a longer stroke than stock. You do this by buying shorter pistons and/or shorter connecting rods. This increases the capacity of the engine. I don't know how much is possible with our D17's, but maybe we could get a 2.0l engine. That's basically all you need to make that infamous 170 quote. That and all of those other little NA mods. [IMG]i/expressions/face-icon-small-smile.gif[/IMG]

JoeB16

yea, or maybe you didnt read and/or understand when I wrote "INCREASE IN DISPLACEMENT".

Spider883

iTrader: (2)

a stocker would be nice. i have to call up JE and see. but thats some major money.

Grey

iTrader: (61)

No, I read that. I just wanted to make sure you understood that. So there's no argument here. The question at hand has been answered and your first response to this thread is oh so out of place isn't it?

JoeB16

stRoker, not stocker. "Stroking" an engine increases displacement without boring out your engine. This is usually accompliushed by adding pistons and other internal pieces which allow the "stroke" of the engines pistons to become elongated and therefore increasing displacement. Grey seems to either be unaware of that or is just posting things without actually READING my replys [IMG]i/expressions/face-icon-small-wink.gif[/IMG]

dude you could just buy another 1.6el and tie it to yours with fishing line and get 170hp lol. seriously though i dont think you could stroker that engine to 2.0l thats just too big my brother knows more about it than i do and when i asked him what he thought he just laughed at me lol cry. dude why did you pick 170 out of the blue is that like the magic horsepower number or something lol. dude did you get intake exhaust headers cams radiator brakes and all that stuff yet lol. dude if you did its gonna get harder after that at least thats what my brother says lol

JoeB16

no, it was pretty damn funny if you ask me. lmao@"gerbal".

JoeB16

Yea, stroking a 1.7l is much harder then stroking a B16 1.6l to 2.0 liters...

Geee, I think thats only been done a couple of hundred thousand times before...

the only thing that would make it "harder" would be lack of premanufactured engine internals for said engine. difficulty of the process however, remains the same.

lastweek

dude did you even read what i wrote i mean have you ever tried to stroke a 1.7l to 2.0l lol. my brother tried but it is a lot harder than i think you think lol. its easy to stroke an engine an even amount of liters like .4 but it is really hard to do .3 because of the natural vibrations of the engine lol. first you need a whole other harmonic dampener to keep the engine from rattling the car apart and that is tough to get for a 1.7 because there arent many of them around but you need more air and fuel too but not too much it is easy to add the air and fuel to the 1.6 again because of the even increment of stroking with the 1.7 if you make a mistake you can get little rocks in the engine and then you have basically screwed the whole thing up i mean there is a lot of planning involved in this lol

JoeB16

oh yea........... rocks i forgot about those.

edit: i didnt notice who you were. My bad, please forget the reply i made to your post [IMG]i/expressions/face-icon-small-wink.gif[/IMG]

To get 170hp is pretty hard from just port polishing and an intake.Try getting at least a 50 shot of NOS.

lastweek

dude can you read i guess not he said no nitro lol. i hate liars lol

DC5@EM2

I think that where he got 170hp is from that honda concept civic that had P&P done, throttle body, and other parts. But I dont trust what they say because honda is notorious for not stating the true horsepower of their cars. Thats the only thing I hate about Honda.
