I was originally hesitant on this purchase, and even reached out to KC Turbo's support ahead of time. There's a lot of great reviews on this but it seems like most have larger injectors and/or have tuners or other supporting modifications. Living in CA I'm not tuned (too much $$$ for legal tuning) and won't be installing bigger injectors*. I'm pretty limited but I do haul and tow and was looking for better low-end performance. I have been running this turbine wheel (along with my old SPTurboost billet 5X5 compressor wheel) for a few days now and am liking it. During the rebuild I did also install the 360 degree bearing kit, and fixed some exhaust leaks around the exhaust snail but overall there's a big difference in where the power comes on now. I'm noticing much better performance with a lot less throttle input. It's too early to tell but looking at the fuel gauge, it appears that I'm getting a bit of a boost in MPG as well. These are all good things! I am looking forward to seeing what the performance is like while towing soon.

* - I do have some minor CA legal mods, including a 4" Magnaflow exhaust, 6637-style air filter (Donaldson), and have unplugged, but kept, the EBPV and using an aftermarket plug to keep the check engine light off.

Just rebuilt my stock turbo using the KC S300 turbine Wheel with the kit everything went smooth and easy.

I've yet to install my items, the quality however is there. The rebuild kit for my turbo is excellent. The turbine wheel is stout and looks awesome! Can't wait to get my project complete! Would recommend products and seller!! KC Turbooooooos!!!

Awesome

I have a '99.5 F350 CCLB 4X4 ZF6 original injectors .84 housing

I've done the normal recomended towing mods; Diamondeye 4" turbo back, H&H with Racor120, RR FRx, 6637, RR 4+4 billet wheel, traction bars, Helwig swaybars, TS6 with Gearhead tunes and even a spare chip with canned TS6 tunes. I also have an AEM water/meth kit thru the deleted AIH plug.

We tow a 12,400# 38.7' 5th wheel cross country every summer for years from OK to CA to visit inlaws stopping @ every National park on the way, Yellowstone & Carlsbad being "on the way"

I tow on grades and flats. I know my truck inside and out. I did my mods one item at a time to see it's effect on towing. I also have EGT, post filter fuel pressure, mechanical boost, and oil temp A pillar gauges and torque pro for monitoring.

So the turbine. It's awesome. Get it. It alone lowered my towing EGTs 200-350* depending on the tune and up to 500 when i turn on the water with a 500ml nozzle. I tried it with a 7+7 and it went back to stock EGTs changing just the wheel. I'm on FTE forum and most there that have this turbine don't pair more than a 5+5 wheel without having larger injectors. I can run hotter tunes than i use to towing. I can maintain 1100* without water with the +40hp tune uphill in 6th gear, or turn it to 80-100hp with water and touch 1200*

This isn't a real SXE T4 or it's results, but for the price it did more for towing than a billet wheel of the same price will. You will need to buy a turbo bearing kit to install this
