Import Stroker motors
 

Are people making stoker motors out of import motors???
In chevy land its very common to drop a 400crank into a 350 and make 383.Also a 283 crank in a 327 makes a 301.
Also in ford land they I believe drop a 351 crank in a 302 to get a 347.
If anyone knows of this,list the combos.

yeah i saw a few. i think crower makes them for the b18 engines

You could drop a B18b crank in a B18c.

Or a B18 crank into a b16.

Or get a custom kit with which you usually get about .2 of a liter gained in displacement.

I know they also have a stroker kit for the SR20DET(Nissan Silvia motor) that adds an extra .2 liters as well.

Thanks for the info.I was just curious.Do you know what kind of machine work it takes??Any sites that have articles on stroking and boring??

B eries engines are like Legos. You can take any crank you want and stick it in any block you want. Since the bore size in all of them (B20 excluded) is 81mm, you end up with the displacement of the engine the crank came from.

Crower, Jun, and Toda all make stroker kits for B series engines. Machine work is virtually non-existent. Boring can be done up to 84mm, 86mm if sleeved, depending on who you talk to.

Heck, as far as the kits go...I've found A'pex even makes a 2.9 L stroker kit for the RB26DETT....just thins the walls out so much though, don't think itd be worth it.

If you bore a honda block out to 84mm with out sleeving you will be out of the sleeve and into the aluminum casting, hence the reason why the B20 is a totally different cast and sleeve.

that is true only for the b series engines i think. i know for sure the f22 is an 85mm bore and the h22a is a 87mm

of cource, you cant bore an 85 or 97mm block out ot a 84mm

remeber when you stroke a motor... you cant rev as high... for the most part.

doesn't that lisa kubo chick run a 1.6 block stroked to 2.0?

I seem to remember hearing that somewhere

and i know jun makes a bunch of stoker kits that allegedly can rev just as high if not higher than before (obviously for the higher revs you need valvetrain work)

don't mean to sound dumb...but what exactly is a stroker and what does it do?

Stroking a motor increase the displacement of the motor with out boring the cylinder walls.

IE you decrease the length of the connecting rod or you decrease the stroke (stroke is the distance between the center of the crank and the center of the part of the crank that the connecting rod bolts to.

this is a link to a site with a good picture... A is the Stroke.

The reason SOME people say stoking a motor is bad is because it can screw up a "good" Rod/stroke ratio.

that's when you divide the length of your connecting Rod by the length of the stroke. If this ratio is too low or too high it puts much more stress on the connecting rods, pistons, and cylinder walls.
It's also been said that there are massive increases in torque depending on the R/S ratio however more and more people are refuting that claim nowadays.
