finally got my truck driving again with my s366 and all i have to say is wow. its a 66/74/14 non-gated borgwarner with the extended tip and t4 foot. its suprisingly responsive with stock injectors but is laggy. just wanted to say if you are looking for a new turbo to have room to grow but not pushing a ton of fuel yet, this turbo does the trick. i spent a total of 805$ after turbo intercooler boot, clamps, and t3-t4 adapter. install was very straight forward and would do it again any day. the only problem i ran into was the oil return bolts they werent stock thread size and i had to get some grade 8 3/8th's bolts and that was solved. now the fun.. this turbo whistles LOUD and sounds wicked. cant wait to install batmowheels! will be looking forward to writing back again down the road and keep everyone posted on my success and luck with the s366!
