Hi Jeff,
I have a BAR sticker from a ref for my 2.2L conversion. If I plan to upgrade to a 2.5L engine, I was under the impression that some folks in CA were installing the 2.5L without modifications that you indicated below. When the SMOG tech scans the BAR sticker, how will he know the engine is a 2.5L and not a 2.2L? Since the 2.5L is a cleaner engine, I would think the 2.5L will pass the smog test with no problems. Does the smog tech test for a ODBII?
Best regards,
Craig, SF

It looks like you already have a running 2.5 so the short answer is
"no", unless you are close friends with a SMOG station which means
you'll be going down that road every two years. BAR won't go near
anything OBDII. Best to have the BAR sticker and swap the bottom of a
2.2, IMHO.
A SMOG legal 2.5 can be done and its done more frequently these days
but you need to start with a 2.2, get your BAR sticker from a ref and
then whack a 2.5 bottom end on the 2.2. You keep all your wiring and
upper engine stuff, heads and exhaust. You can shorten the rods for a
bit more torque or use different pistons and get different compression
ratios to suit your needs. You'll pass SMOG with 2.2 specs and pick up
almost 30 HP over the 2.2.
Welcome to California!
