Good point. Don't know why I missed it.

No man, holy crap. I know you guys have good intentions but stop
spreading misinformation. All of your original questions about Si/VTEC
engines on the del sol can EASILY be answered by doing a quick google
search. As a buyer you seem confused about the various engine
configurations avaiable on this car. I think it's simply because you
don't understand how engine's work. Head over to howstuffworks.com and
read all the major articles about how cars function. You will find out
the B16A3 in 94-95 del sol, and the B16A2 in 96-97 outperforms because
of 1)slightly higher displacement 2) higher compression 3) higher rev
limit but most importantly it's a dual cam engine meaning intake and
exhaust stroke has seperate lobes on the camshaft. Please stop spelling
it vtech. Vtech is a phone. VTEK is a spark plug. VTEQ and every other
bastardization of vtec makes me roll my eyes when i see it posted.
I own a isle green 95' del sol VTEC.

but to answer your original question. the only way to ID for sure is to
run the VIN. Even then, people very often swap out the D15's and drop
in B16/18 etc. Don't go by the valve cover it can easily be replaced.
Look at the engine block stamp. Don't buy a car from ebay if you want a
daily driver. Use autotrader. And don't buy a swapped car unless he has
receipts proving the work was done professionally. Too many kids in
garages think they know how to slap in H22's in EG hatches.

VTEC models had ABS. Some Si's did as well. Honda varies the car
specifications by region. For instance cruise control was not available
in canada etc. ABS in my opinion is pointless in the hands of a good
driver. Learn proper threshold braking. That's the way.
