in todays video i install the turbos onto the block. when i was diagnosing this engine i met a really cool guy through the facebook groups. he happens to be a machinist but also has an n54 that he has modified and worked on extensively. he messaged me trying to help and was one of the only ones who actually made sense of the whole issue with the coolant mixing in the oil and the misfire and it turns out his theory was 100% correct. after chatting he let me know he rebuilt some oem turbos with upgraded chras, new waste gates and ceramic coated them. he sold them to me for a good price and so far i am really happy with them. we also do downpipes, engine harness, waterpump, thermoastat ect.
