Whats the difference besides the obvious

Usdm - has egr, map and other tabs
Jdm 8 - no map or egr
Jdm 4 - no map, egr or tube

Is that tube on the runners for the pcv? Is there any other thing Im not seeing? Read the evo 8 is good up to 700+ and 8300 rpms, cant find anything on the jdm 4 but it looks like the same. Any thoughts?




So this is a Jdm Evo 4 or is it something else? Notice it doesnt have anything like the above, is it still the same power and rpm output as the usdm 8 limit...

 

1 more hour till the auction ends, hope some rock solid info gets posted up before it ends.
