is it me or does the search suck... u type in something and get a biliion other useless items...lol.. i even tried typing "DIY" and it said no results found... shesh oh wells what i was wondering is there someone or something or someplace that can increase displacement in our engines..??

new rods ... longer stroke ... or boring the block

oh.. lol... i knew that.. i guess i should have been more specific... lol.. but what products and stuff.. u know what i mean

engine swap... there is no stroker kit for the D17 unless you go full custom which is a waste of time..remember.. there is no replacement for displacement

This phrase is almost true except for the fact of forced induction. It kinda levels the playing field a bit.

Displacement can be increased as Asnsurfer said......increase bore or rod stroke. Only ways other than a swap.

No, the phrase is true. A larger displacement engine will make more power all other things being equal.

The concept with everything equal, is true, your right. With the displacement of a 5.0L Mustang, the displacement is much more than a Civic without a question, correct? Then with the addition of forced induction (turbo or supercharger) the Civic can now beat the 5.0L Mustang. Reasons behind this: significantly less weight and the addition of forced inducrion. This is how a local kid has an 11.2 second 1/4 mile CRX. The addition of forced induction with weight reduction levels the playing field of displacement. So the phrase holds validity....I was never denying that. Merely stating the concept is close minded and there are exceptions to it.

There are no exceptions to the all things being equal, the larger displacement will make more power. It's simple fluid dynamics. I'm not refering to wether or not a 5.0 mustang can be a turbo honda, I'm talking about 2 identical engines with different displacements.

I'm working in theory. You're working in application. :-)

Exactly. Theories........they all sound nice until application, which really proves or disproves it.

 
Rep Power: 0

Yea it is a proven theory, so technically it is "fact." A larger motor WILL make more power, but when you have a shitty big motor vs an efficient small motor it levels the playing field.

You can increase displacement on the D17 by doing 2 things.

Either by stroking the motor or going big bore on the sleeves. I dont recommend the stroking method really since it deals with so much more custom parts and that means more money. A stroker setup will need a custom crank, custom rods and possibly custom pistons. That alone will set you back close to $1500-2000 and thats not even touching the block yet. And also, since they are custom parts, if somethign happens, its harder to replace the parts and cost more if they do.

The other choice is sleeving the block. We do big bore sleeves all the time for the D,B, H, K and F series blocks. On a d-series, we usually go 2mm bore bigger than stock to increase displacement, for forced induction applications.


BUT: As much as I'd like to think bigger is better, its not necesarrily the best way to go. We have built 600HP B-series motors on the stock 81mm bore. The block is sleeved, but we keep it at 81mm still. When you are going turbo, concentrate more on the fuel management,etc rather than the bore size. We already know we can make power without going big bore.

Chek what the fraise sais "There no replacement for displacement", yes there is that forced induction, that why you could have an Audi A4 with a 1.8t I4 or a 3.0 V6, they may not have the same power, but you could raise the power on the 1.8lt and none would be the waiser, that the advantage of a turbo or supercharger, you could add HP's without increaign displacement........

Ever seen a turbo big block vs turbo honda?



There. Best of both worlds. Hows 2000+ hp sound? Ever do that in a 1.8L?

Actually all the HP in the world does not matter if the power can't be kept and distributed to the ground. I have seen some big block boosters myself...

F1 cars are putting out 100hp for every .1 liter of displacement. More efficent right. So that 1.8l theoretically could be at 1800hp.

There is a replacement for displacement. Forced induction be thy name.

Big blocks are made to make huge power...thats why they're made. Huge displacement=huge power, you put forced induction on that of course you're making more power. I like the harder things in life...anyone can make a big *** motor push 500whp, but getting a 2.0L to make that much horsepower, and being able to control it ie: put it to the ground when and where it should be...thats power, not power of the motor, power of the builder...ie: elegance and engineering in my opinion

 
Rep Power: 304

F1 would be even sicker but they have put a limit on HP(Still disgustingly fast). You know abou the tracks being modded for safety purposes.

You also have to realize what kind of RPM an F1 motor spins in order to make that horsepower. The torque is ~250 ft/lb.
