Long Rod 2.0L questions

You can use off the shelf 2.3 stroker pistons. And I guess reading more the biggest benefit is the combos ability to rev as pretty much everythingon the piston below the wrist pin is removed.

I made a critical error in my haste yesterday. Long rods are 156 long, not 154... not sure why I posted that.

This would bring the B/S ratio to 1.77

That being the case: The stock 2.0 piston has a 35mm compression height, with 0mm deck clearance. The 2.3 Wiseco stroker pistons (using them for this example since I have the numbers handy) have a 28.7 compression height with a .3mm deck clearance. Assuming you use a 156mm rod:

35-28.7 = 6.3. so you would have a .6mm final deck clearance.

If you installed Wiseco's stocking piston: K571M855 (28.7mm), with the long rod (156mm) and stock crank (88mm). You would end up with a final static compression ratio of 7.4. That seems far to low to be able to rev that quick.

I'll hunt down some numbers for other stroker pistons.
