to end this discussion...and if anyone cares...you cannot use the vtec oil jets in a 2.3 block. while it will definitely bolt up, it will pose problems for other parts. its not the crank that is the problem although they came very close. the problem is the piston, before it can reach btdc it will touch the oil jet. so there goes that idea.

for enlightening purposes...i had put in my balanced 2.3 crank into my jdm 2.2 block with the oil jet installed. i just put in my pistons/rods (type s pistons/usdm 2.3 rods) today, and i found the true reason it will not work as stated above.

hope this helps with any confusion
