The other night I was having a discussion with my roommate about stroker kits. We are both not very UP on how these work. So for you gear heads what would someone expect to gain from this? Are they available for the Si? Is it difficult to do or get done? Would you recommend? Why or why not?

 

increase your engine displacement...from 2.0 to 2.2 for example...parts include piston,rods..etc...

etc. being a new crank. which is what makes a stroker kit a stroker kit. The stroke changes, meaning you have to change rods and pistons to compensate for the longer stroke in a block that is the same size. This does effect rod ratio, alot of times negatively. The positive being the increase in displacement like the OP said. Their are several k20 stroker kits out there, but until we have programmable engine management (ie. K-pro) there isn't too much of a point for us.

read the second half of this:

I believe BC has a stroker kit available for the K block

 

^^ Yep:

But like IT GUY said, until we have some programmable engine management, there won't be a point in getting it. Unless for some reason you wanted to just get it and wait to install it until we do have the tuning support

 

honda has did alot of R/D for the k20 so it is well balanced. I think going to a stroker would lower the amount of RPM's and change the the smothness and balance.. but thare is no replacement for displacement.. im not 100% on that JMO! what do you all think the pro's and con' of a stroker are?

 

Aside from bottom end torque I don't see much point - good for the street I guess, but not for racing. I read about some european racing teams that raced h22 powered accords. They actually destroked them to 2 liters and build them to about 300 bhp, NA!

 

As mentioned earlier, Honda has spent millions designing this engine as a 2.0, its all part of getting the perfect rod ratio and engine balance to not only make the engine rev to 8400 RPM and still make power, but also be reliable.

Changing the bore and stroke and still trying to run it up to 8400 could cause plenty of adverse effects on reliability, so I say build the 2.0 as it is, or just boost it. Not to mention a K24 can be built for far cheaper than a stroker kit and probably give better results.

actually honda made a destroked DOHC VTEC motor for the european accords that was based on the H22... called it an f20 (before the S2k was around, not the same motor whatsoever)

 

That could have been it then, I thought it was an actual H series - no matter, I'll take high revs and volumetric efficiency over low end torque any day

 

preachin' to the choir... that's why I like honda motors.. it only makes sense to enjoy the k20's, f20's, and b16's out there.. they may not make the most torque but I feel like they are the most "honda" of the honda motors..

yeah, the f20b's pretty sweet/little high compression motors. When I had my first accord, I was looking at the h22a for boost and the f20b for N/A options. The f20 just seemed to be more of an N/A motor

 

Oh c'mon, the H can hold its own when it comes to NA too, don't hate!

 

lol... I definitely wasn't hatin

And that's why (had I owned the car long enough to do it) I would've gone with the h22... it can hold it down all over the place. N/A, FI, whatever...

Plus it gets pretty good torque numbers
