Could anyone pinpoint the differences? Other then the "8 hp" gain for the JDM one?

Do they have the same compression? How come the JDM one produces 8hp more? Higher compression?

 

a lot of the differences are due to our emotion laws... Not sure on the compression...

 

Yes, compression on the JDM motor is higher. That is mainly the cause of hp difference. I think US is like 10:1 and JDM is like 10.6:1. Something like that.

 

Do they also come equipped with LSD?

They have bigger stock cams to I heard

 

...here read this thread (should answer your questions):

Thank you very much.

 

So, will all the other parts be the same when it comes to replacing worn items: belts, plugs, wires, distributor cap, rotor button, etc.....

Thanks!

 

The JDM B18C does indeed have higher compression (10.6:1 vs 10.0:1). But this is certanly not 8HP worth of compression. I am not sure about cams, though. But the JDM B18C is certainly tuned more aggressively to take advantage of their better gas.

 

yep!

The compression is higher on the JDM engine, mainly because they don't have strict emissions restrictions, and they can use higher octane fuel..
