I have my turbo out and while its out I was going to have it rebuilt for good measure, I have someone who can do the rebuild for me but while he had it apart I was wondering if it would be worth it to upgrade the compressor and flywheel. I found a few options for that online but I am somewhat new to the turbo world and not sure if these upgrades would be worth it and actually improve anything. My goals for this car is around 300 WHP. I have listed the options I have found below. I really appreciate any guidance or input you may have.

K26/6 upgrades compressor and turbine upgrades?

You might want to consider Charlie at Evergreen Turbos to do your rebuild. He's done thousands and has time-tested (no risk, no finger-crossing) options to suit just about any goal.

Your rebuilder and those other parts might work out fine, but I mention Charlie because you say you are new to the turbo world, and thought it worth alerting you to to the 944 community's go-to guy.

I called him, his raptor build is a little outside of my budget right now but he for sure does sound like the best optionTom wrote: Mon Apr 21, 2025 6:38 pm You might want to consider Charlie at Evergreen Turbos to do your rebuild.

It was around $1200 I believeTom wrote: Mon Apr 21, 2025 6:51 pmCan I ask what he's charging these days?TerrorBytes wrote: Mon Apr 21, 2025 6:46 pmI called him, his raptor build is a little outside of my budget right now but he for sure does sound like the best optionTom wrote: Mon Apr 21, 2025 6:38 pm You might want to consider Charlie at Evergreen Turbos to do your rebuild.

I am pretty skeptical about those websites. Lots of garbage out there on the internet.
Personally I would not put those pieces in my car.
I would save the money and go with Charlie for my car.
Or save up and see if Chris White has a Zona Rotor that would work better for you.

I actually bought the 9 blade turbine and billet compressor wheel for the project car since it already had a damaged compressor wheel and the turbo needed a rebuild anyways. Lindsey racing does the same upgrade when doing rebuilds on the k26 and they charge $350 for the compressor wheel and $350 for the turbine wheel. I bought mine from Mamba and Kinugawa on eBay. the turbo is being rebuilt by Long Island turbochargers since they are near me. It will be matched with a k26 Vitesse chip and 3in exhaust and Storch MAF that the car already had. I don't think it will reach 300RWHP on the stock injectors but maybe. Planning on running it at 15psi.
A K26/6 will struggle to make 300hp without using really high boost. You will also need bigger injectors, 3 bar fpr, and a good chip tuned for those components. A k27/6 makes just about 300hp with those upgrades.
Coming from someone who chased 300hp, if a K27/6 is out of your budget then I would focus on drivability. Keep in mind that 300hp only gets more expensive. Fast spool up with nice torque downlow. I would spend on a good sport cat and muffler, it does help with spool up. I would also get an A-tune or MAF (you can buy my A-tune). Again, not for hp but drivability. And suspension. If funds allow.
