    Fleece Cheetah Or 2nd Gen Swap?

    Hello community.

    If you have done these upgrades, I seek input/feedback on the fleece cheetah or 2nd Gen swap.

    I like my exhaust break, but I don't have to have it.

    My truck is deleted and tuned.

    I don't race it or abuse it, and I'm not trying to get it to perform no 600+ horsepower.

    Any feedback would be greatly appreciated.

    Re: Fleece Cheetah Or 2nd Gen Swap?

    I have done both routes.

    They have honestly two different attitudes, and both have pros and cons.

    VGT Fleece Cheetah turbos are, in my opinion, the best company to go with for a drop-in application.

    For one, I had purchased mine to be installed at an unknown shop and had gotten foreign material inside the turbo, which was not allowing the EB to work as it should.

    With no questions asked, they had me send it back and rebuild the whole thing with only paying shipping one way.

    I don't have anything to pull, and I did no research on my behalf before buying, and I wanted a power platform to build on.

    I'm using Fleece as an example, but any VGT setup is the best for towing any application.

    The reason is that they are designed to give a lot of low-end torque.

    The bottleneck is the actuator, and the way the stock exhaust manifold is designed prevents the gases from leaving the motor, which you tend to see higher EGT with the VGT setups.

    You can still buy aftermarket applications to correct this issue and still have a good and solid motor, but I was still skeptical about the actuator leaving me stranded down the road.

    With the 2nd gen swap kits, they run the manifolds equally, as the flange is A T4I " it has a divider in the middle of the flange " that proportionally disperses the gases out of each cylinder equally.

    This allows a better flow rate and A substantial reduction in EGTs.

    They are still towable but require "67mm Turbo's" fuel components to spool the S400 frame turbos.

    This, often or not, can or will haze or smoke while towing.

    Turbos are much cheaper on fixed vane vs. VGT, but you can get actuator replacements instead of the whole turbo.

    With the 2nd Gen route, you will need head studs.

    You're allowing more air into the motor, as well, with added fuel.

    Regardless of whether you have injectors or not, tuning is required for the swap, as the S400 frames are more significant, have more airflow, and have more fuel, which means you'll be demanding your stock injectors to be maxed out.

    Most companies will strongly suggest studs and injectors with the swap to work as efficiently as they should.

    67M Turbos are when you will need A bigger CP3 pump, push rods, and valve springs.

    What I guess I'm trying to say is that the upfront cost of a 2nd Gen kit is spendy to do it right.

    The VGT setups tend to have the dreaded actuator issues and higher EGTs.

    If you aren't seeking power and tow, go the Fleece route, and if the actuator ever goes out, get the city diesel actuator, as the turbo itself will last quite a while.
