My 2000 F250 SD with 330 000+ miles had a very noticeable "turbo whine" lately. I decided to rebuild it on the advice of Clay at RiffRaff Diesel Performance, however since he was out of stock of the turbine wheel, he recommended KC Turbo for the part. I received the part fairly quickly, had it balanced with my turbine wheel (as recommended by the KC Turbo tech) and using the KCTurbo rebuild kit for the Garrett GPT38 turbo, it went together smoothly (the original turbine wheel was damaged with parts of the vanes missing). Test drove and I immediately noticed a quieter turbo and lower EGT's by about 100 F. Taking a long trip soon and will check for fuel consumption improvements. BTW, be sure to inverted the assembled turbo on the bench, fill bearing cartridge with oil and spin the turbo unit to completely oil the bearings prior to installing back in the truck to avoid a "dry start". Very pleased with the performance observed so far.

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
