There are engine codes on the engine. I forgot where but some place on the net posted all the egine codes. I do not know if this would work but you can try taking one of the spark plugs out and see if the pistons are high compression. Usally the have a raised face. If i am not mistaken I thnk the stroke is different too or I could be wrong

I just want to know for all you guys with the JDM 10 to 1 motor ----How much of a difference did you feel compared to your us spec sr20de?

Does anyone have any time-slip times for a JDM sr20de? I was just wondering how much faster the 10-1 compression would make it. No Bullshit guys ok lol---I know it is faster I just want to know time down the 1/4 mile. In a b13 or b14 must be in the high 14,s right?
