Series 4 Or 5?
#1
I've got a 4-port that has the stock Hitachi 18S-2S turbo(the fat one)& supposedly this means it's a series 5 motor, but I'd like some confirmation or some way to absolutely ID this engine....no other marks available on the exterior. THANKS!

s4 has a threaded hole in the front of the center housing for the knock sensor,
s4 also has 2 bolt metering pump, aluminum 2 bolt thermostat neck, the turbo/ manidfold flange is at an angle
s5, has threaded holes above the spark plugs for the knock sensor, 3 bolt metering pump, 3 bolt plastic water pump neck, turbo/manifold flange is vertical
theres more than that, those are the easy ones
