stroked b20?

I know eagle has a stroker kit for the b20 has anyone here done this? if so what type of hp/tourqe on a na motor. or on a turbo motor. any replys would help.

thanks Crazzysol

Useless on a turbo motor because you just make more unuseable torque at lower RPM ranges. On a naturally aspirated motor you might see a 10-15 peak horsepower gain, but a lot more area under the curve.

^^^^ I disagree with it being useless. If you have more displacement, you will have an easier time spooling up the turbo.

Theres no replacement for displacement. huh?

I like to think of that comment un-thought out because if your forcing more into a cylinder, technically it will have a larger displacement. N/A or FI, muscle or import, without displacement it wouldn't be an engine.

Btw, I saw a stroker kit for the b20 in a magazine and if I remember correctly, for 2.1L it was 6% hp gain and for 2.2 it was 11%. My guess would be its the same for both N/A and FI.

Here we go.. A company called Eagle has a stroker hit for the B20. says +6.0mm stroke increase for a displacement of 2156cc which is a 9% increase.

Though I do question their unfinnished website.

And wow, what do you think that does in a FWD car? Boils the tires off 500 RPM's quicker. In other words it's useless. For the 900-odd dollars you would spend on an eagle stroker crank you're a thousand times better off to get the motor sleeved so it can take more boost and power.

it depends on your final drive and gearing if you are going to burn the tires. with a ITR final drive and GSR transmission, you probally will. but with a LS transmission and stock(4.4) final drive, itll probally be fine. btw, one of the fastest all-motor civic is a b18c bored and stroked to 2.2l(Leslie Durst), hitting boost can also cause loss of traction....

Its not necessary to stroke the motor when you go turbo. Usually all motor guys (like me) would have to squeeze out as much power as we can to be really fast. My friend still has a 1.8 gsr turbo powered 92 hatch running low 11s.

thanks guys
