Hit the threshold driving home last night. Truck has been boosted for the last ~60,000 miles and daily driven. Couldn’t have done it with out an amazing turbo kit by Trick Turbo and tuning my New Era Performance. Bone stock 5.3 engine. Black ops 60lb injectors, Trick Stage 2 kit, built 60E and Yank TT3000 converter. Buffalo winters, road trips up to 8 hours straight, pulling car trailers and rvs, countless 4x4 but outs and dozens of 1/8 and 1/4 passes.
I have not once removed the turbo or kit for any reason since I installed it. There has not been one issue ( besides breaking front cv shafts from but outs ) w the truck. For the last two years I haven’t done a thing to it besides install a 2 step to show off with, change the oil and Trans fluid and filled it w 93. I still get ~21 mpg on the interstate @70mph and 15 give or take city mpg. Thanks everyone who has helped or that I might have helped, I love this truck because it’s fucking kick ass.
Congrats! Shelling out the money for a built-transmission is the main reason you have made it. The 5.3 with a turbo, good tune, and good fluids should have no issue, but a stock 4l60 would have exploded miles ago.
Choda, have you ever driven a fast diesel like a modded 6.4l ford or similar? How do you think this compares to something like that? Is the truck dyno tuned? If so, what does it do torque wise for towing? Any details on the transmission?
what I remember hearing (but I might be wrong)…
not from carbon… years ago gm would measure and match parts for assembly and clearance specs… in later years they would find a mean/avg size and just use that rather than measure sizes for each cyl they didn’t have to meet a clearance spec, but had a clearance range…, that on top of the piston skirts getting smaller added to the slap sound…
ive heard of cars/trucks doing it for 200k miles with not a problem…
might be off base, but that’s what I kinda remember about it.
Yes, its mostly due to short skirts. They cut down on drag to help fuel mileage. My early gen 5.3 has piston slapped when cold for the past 120k miles, after 30 seconds it warms enough, pistons expand and it goes away.
TUNE is #1 . I had a stock 4L60E when I was over 400 wheel and it was fine. Never missed a beat or did anything that would cause worry. I had mine “built” when I wanted more power and bought a converter. So it had to get pulled out anyway, might as well upgrade some transmission parts.
Yeah I average ~15k a year. Two years I was over 20K but that is not reg annual mileage.
Yes, my brother had a nasty 7.3 Ford. It made a ton of power and was decently quick for being on 37s. If he kept it on stock wheels and tires, it woulda flew. My truck is faster and feels about the same. From a roll it roasts tires in 2wd anything around and under 40. From a light in 4x4 and the 2 step, its an animal. 1.7 60 foots. My torque number was 566 at the tires, so its decent.
