I was looking into buying a new motor for my build up. I keep seeing ones listed as JDm engines, but have been told they are usdm engine. What is a way i can tell for sure that a motor is a jdm engine? Also what is a good tuning program for a non Vtec, boosted SOHC engine. Thanks.

 

us motors end with number b16a2,b18c5,c1 and jdm dont b16a,b18c,b18b,b20b. u get the point same for sohc

 

cool, but what about a tuning program? i haven't ever actually tuned a car, but there is a guy in town that can, i just need to know what to run.

 

crome basic is free and a great program

 

x2. crome pro is also worth its money i think as well. crome is still a good base program though.
