As far as I know you'll gain .7 compression. I am 99.9% sure you will be fine with an AP2 crank. While your at it you might as well go stroker, Accord k24 cranks r cheap. It will be perfectly driveable.

You can use the AP2 crank with AP1 pistons and get a CR of about 12:1. Or you can use AP2 pistons and have a CR or 11:1.

I think we need some clarification.....


What he is asking is if you can use 2.0L rods and pistons with a 2.2L crank. Remember that these are the 11.7:1 JDM pistons too.

From what I know you can not use the 2.0L rods and pistons with a 2.2L crank.

Many people say that you can use 2.2L crank, 2.2L rods, and 2.0L JDM pistons to achieve a compression ration of about 12.65:1. That means that you need stand alone tuning from AEM or Hondata and you will have to run race gas 100% of the time. If your supercharged this compression ratio is way too high.

You will also have to have the block machined to for the longer stroke of the crank & rods.

I would just get a Spoon or equivalent stroker kit with JDM pistons to match it and call it a day. Either way $$$$$

if any option of rebuilding your stock motor is more then 3k, call laskey racing.

3550 shipped gets you a built forged bottom end sleeved with your choice of CR

OR

inline pro i think is 4k plus shipping, but there reputation is stellar
