TL engine parts in Accord?

I've searched around, and was surprised not to find a discussion of this already. From what I know about engines (which isn't much), displacement and compression ratio is a factor of cylinder bore and piston stroke (as well as gasket height, etc.). I see that the V6 accord engine has 86mm x 86mm bore and stroke, with a 10:1 compression ratio and 3.0 liter displacement. I also see that the TL engine has 3.2 liter displacement with 11:1 compression. This would make me think that the TL engine is running a longer stroke, to get the extra juice. I couldn't verify the numbers, but I saw one site that listed the bore x stroke of the TL engine as 89mm x 86mm (not sure which is which).

So my question is this: Does anyone know for sure what the bore and stroke of the TL engine is?

And secondly, if the bore is the same and the stroke is longer, could we swap for the TL pistons? Is it really as simple as that, or would there be a ton of tuning and new computers and what not?

89 mm bore x 86 mm stroke. You'd have to bore out the cylinders to squeeze that extra 3mm in there. I'm not sure if the cylinder walls are thick enough to tolerate it. Does anyone know if it shares the same block w/the 7th gen Accord 3.0?

Regarding the increase in compression--it's likely due to head changes. The head's got less air space in it, prolly.

Not necessarily. Just boring an engine will raise the c.r., all else being equal.

Really? Wouldn't a wider chamber have more area once compressed?

The TL long blocks are actually very cheap if you want to go to the trouble of getting that extra 200cc. They are around $1500...that's with the block, crank, rods, pistons, no pan, etc...
