It may be a 2nd gen b16a with a obd-1 PR3 ecu, if it's jdm. The obd-1 PR3 I have is long like the ecu on the left.

i would need to see the bar code sticker on the ecu in order to determine weather it's jdm or usdm. cuz there are jdm ecu regular size as well.

OT a bit, but the first semiconductor microchip/cpu/microprocessor - the 4004 - was designed and produced ALL by Intel. It was designed for a calculator though.
My only guess about why JDM's are smaller are cost of materials. SMD parts would be cheaper there, while large bulky parts pose no warehouse storage premiums in the USA like they would in Japan.
