Hey I got my 'JDM' TII motor today and am a little leary of it. The company I got it from had a ton of S5 motors and they said they got a few S4s and they were all bad and finally got a good S4 imported that they sent me. My concern is I am thinkin they might have sent me a s5. Whats a dead giveaway of the TII S4 vs S5. This is the first time Ive ever seen a TII motor even.

 

s5's have plastic thermostat covers.

search.

 

Thermostat cover, Turbo Manifold/Turbo, OMP, and im sure there is other stuff im forgetting.
