Hi everybody, I was just wondering if the JDM 13b-t from a fc3s rx7 in japan is better/quicker then the usdm "American" version of the 13b-t ? and would it be better to swap in a jdm 13b-t into a usdm fc3s ? thanks for the help

 

No, it's the exact same thing with a few minor changes (mainly emissions).

 

thank you, so you think it would be smarter to just build on the stock 13b-t ?

 

It doesn't matter. They are the same engine.

 

i know that....i just thought it might have some little things that would be worth buying it for but i wasn't sure so i just wanted to ask thanks
