it only took like 3 hours to swap it all over, the other 3-4 were spent cleaning it out since the car it was on prior to mine had been burning oil pretty bad, and it wasn't running right , till i got an idea and decided to put the y7 TB on it and run it again, and voila it ran like a champ. it scared me at first cuz it was a definite improvement. but yeah stay tuned more to come.
