How do u know if the motor is JDM or USDM..I did the swap and just want to learn more bout this ..These number were stamped into the block on the front .
H22A
1001433

And another thing is I found a barcode sticker that said this and Im wondering what it is
M2A4-1000095

Any ideas Thanks

 

jdm motors say H22A, USDM will say H22A1 92-96 or H22A4 97-01. The JDM 92-96 motor is also internal coil distributor.
