the k20 is a 2.0 I want to know if I sleeve it how big can you safely go or should I just go with a k24

Thanks for the help

 

People have gone up to 2.34L with no problems.

In japan they also destroked a k24a crank in a k20a block with ctr b series pistons... gave them a 86 x 96 with around 2.3 L

TOP FUEL JAPAN is going to be selling that stroker kit

 

that is a crazy setup

 

How exactly are they using ctr b series pistins in an 86 mm bore engine?

 

by what I am reading it says k20a pistons and b series rods

 

they have to be modifying the rod in some way because from what i know the B-series rod width is wider then the k-series..

I think they are widening the rod journals on the crank. The small journals can make for durability problems.

 

<TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote, originally posted by Innovation &raquo;</TD></TR><TR><TD CLASS="quote">You can open the journals up on the K series cranks to house a .935 width rod. By doing so you will have to take .001 off of the journal so its recomended to at least use a plastiguage to ensure your clearances are with in spec.

This will allow you to use any custom or off the shelf F20C, F22C, H22, H23 and H/F20C rod bearings rod with your newly reworked K20 or K24 crank

You can also offset grind the journal down to 1.770/1 increasing stroke + or - 3mm and run a custom or off the shelf B series rod

I would recomend re heat treating the jorunals if you were looking into doing this, just my opinion though </TD></TR></TABLE>

Im not really sure why people are so eager to fork over $1000's for stroker kits they can make themselves for next to nothing ::shrugs::
