i just put together one of those motors! i used a 92 civic cx 1.5 bottom end and put a 98 1.6 vtec head and intake on it. i used a 97 ex tranny also for the better gearing. the car is much faster! the cx 1.5 lower end has flat top pistons, while the 1.6 vtec engines have dished pistons with a 9.6 cr
i figure the flat tops would yeild a 10-10.2 cr???????

it took me a little bit of playing with the timing to get it to stop pinging. runs real good now!
