Looking to rebuild our turbo while it’s out. Was thinking of the following but wanted to get some opinions.

KC s300 wheel with the RR billet compressor turbine.
360 degree bearing kit
misc seals

I can get all this from riff raf for approximately $500.

What do you guys think of that? Are there other combos that you think would be better? Looking to keep the stock housing and stuff. Not trying to go crazy with it but I wanted to upgrade it. Plans are to put on an intercooler, add stage 1/tunes to go with the T500 we added. Not making a racer but just something that has a little more giddy up.

Thanks!

 

I was in your position about 6 months ago. I tow alot, about 13000 pounds of camper and jeep every other weekend in the summer. I have a banks intercooler and baby swamps injectors. The truck towed great however in the summer you really had to watch the EGT gauge. On a long hill with the stock turbo and 1.0 housing 1100-1200 was easy to hit. Not wanting to go crazy with turbo upgrades, and having to reseal my intake plenums I decided to give the KC kit a try.

My first impressions driving around town unloaded were Meh at best. boost was lower and there was not visible gains. The difference showed when I hooked up the trailer. EGT's towing on the east coast are around 950 degrees to 1000 when really pushing hard ( pulling hills with the trailer at 70 ) I didnt notice any difference in spool up time, and overall boost is a tad lower than the factory wheel. you may be thinking how does this help me if boost is lower, its all about volume of air.

I recently got back from a cross country trip ( connecticut to cali and back 6000 miles in 2 weeks)The kc wheel in my opinion made all the difference. climbing the eisenhower tunnel fully loaded I was able to do 40 with 22 pounds of boost most of the way, egt's were still 1100 degrees by the top; however I was able to hold it much longer

Long and short if your not towing alot, you wont see any real benefit

 

Well that is very good feedback because I don't plan on towing much at all..........hmm

Is there a better setup/combo that I should look into?

I'm wanting to rebuild it regardless (bearing and seals) so I thought some new wheels would make her a little more fun.

Thanks for your input, very helpful.

 

Im sorry for bursting your bubble.....

 

KC 300 wheel on exhaust side is wider and blades are deeper.
This is going to drive the compressor more consistently.
TJLongworth, what compressor wheel do you have?

 

I have the kc 300 exhaust and compressor wheel,

 

Well my setup is all stock with a little roughed up intake wheel.

If I’m looking at the s300 intake and RR billet exhaust. I’m assuming I’d have to see some “non-towing” benefit eh?

Are there other options that work better for my plan? Read that exhaust compressor wheels are roughly similar across brands.

 

If youd like, I see your from the boston area. Im in connecticut, if youd like i could meet you half way some time and ill take you for a ride in my truck and you can gather your own opinions

 

Thanks for the offer.....maybe once we get the truck up and running after this rebuild and i can get a baseline i may take you up on it.

One other thing i'll add, I'm planning to add an IC and stage 1's but wanted to address the turbo first.

With bigger sticks and a tune, the s300 "setup" look any better, non-towing, over the stock?

 

what do you mean by look ?

 

Look as in how does the combo compare to stock knowing we will be going for stage 1s, IC and tunes.

I know it’s not a bigger turbo but hoping it’s better from an air flow issue if the truck needed it. From what you’re saying, it only helps when needed.

 

The air flow is going to be there all the time since its not a computer controlled turbo like the 6.0 or duramax , however unloaded and around town I dont believe your going to push it hard enough to see a huge difference. maybe if you ran it on a track or dyno

 

This is all just my personal opinion, someone could tell me im wrong and my setup is not the norm and I would be ok with it.

My obs has 4.10 gears and a 5 speed and I dont feel like its ever really working hard without a trailer attached

 

 

TJ, did you stay with the 1.0 housing or go back with the stock 1.15?
