Default What does a stroker kit do?

Does the kit replace the crank so the bottom of the connecting rod travels in a larger circle? Does piston diameter and connecting rod length change? Does it increase displacement and or compression ratio? No specific info in a search... Anyone?

A stoker kit is generally a replacement crank with offset or smaller journals, this increases the stroke of the piston, thereby increasing the displacement of the engine. Sometimes machine work is required to make room for the increased swing of the rods. Increasing your bore will give you a larger displacement too, but you're limited to how much you can overbore by the thickness of your cylinder walls. Increased compression is more a function of the design of the piston, you can gain a few points of compression by milling the heads, the downside to this is that you decrease the clearance between the piston tops and the valves. But all that would be taken into consideration by the machine shop.

MRT sells stroker kits. Do a search on their website, they'll definitely be more helpful than me.

Hey thanks Mark, I'll try the MRT site again. You just gave me more info then I found there the first time. Does any one here have a stroker kit? Do they increase torque but reduce your rev limit?

You can find several manufacturers of stroker kits at www.subarureview.com
You might be able to find more info at each of the manufacturers sites.
