Shows an ESi.

 

honda makes every engine and more in japan.....

any way to actually tell if its JDM or USDM tho ?!

 

Yes. JDM engines will end in a letter (B16A, B18C, ZC) while USDM or other market engines will end in a number (B16A2, B18C1, D16A8)

Knowing the difference between US market engines (B18C5, D16A1) takes more memorization to know the difference between Euro/other engines (B18C6, D16A8)

 

cool thx kai, so how are b18b's represented in usdm blocks ?

thx

 

B18Bs....

 

B18B1

 

it not esi it is xsi and it came with a b16a firstgen and all the rest of the integras were zc at least the old school integras

 

You obviously haven't been following the thread. Integra ESi's came with B18B's.

The second gen XSi, and the RSi you left out, came with B16A engines. That's a generation behind what we are talking about. From there, the rest (ZXi, RXi, TXi) had a ZC pattern engine.

Once again, 90-93's are not "old school."

 

anyway, the jdm would most likely be better because they put higher compression pistons and stronger rods in em
