For those not on the facebook group, Dieselguy86 has been working over the last months/year on building a hybrid turbo based on the stock Liberty CRD turbo. It is a GTB2056 turbine wheel(same as the Ram/Jeep Ecodiesel) mated to a custom billet aluminum compressor wheel. It also has a set of GTB20 variable geometry vanes in the exhaust housing in place of the stock GT vanes. The GTB20 vanes offer better aero than the stock vanes. This is all stuffed into a stock Jeep turbo housing so that it is 100% plug-n-play. Downpipe, oil feed/return lines, intake elbow, CAC hoses all bolt right up. Oh, and he taped a 1/8" NPT fitting into the exhaust housing for an EGT gauge which you can see in my pictures.
The GTB20 turbine is a much higher flowing turbine than we have stock yet should offer similar or better spool. Think 250+ hp. The compressor wheel is a billet aluminum 60mm extended tip wheel with a larger inducer than stock. This turbo should easily max out the stock injectors and give those who want more some overhead for honed injectors.
I just got mine a couple weeks ago and finally got around to installing it this last weekend. Installation was the same as a stock turbo for those familiar with that. I would say that start to finish this was a 4-5 hour job(I did it over two days) and I took my time having never done it before. Removing the overflow tank was very helpful.
One thing to mention was that I didn’t have any issues with the turbo flange studs snapping. I’ve heard this was an issue for some. That said, two of the nuts came off no issue and the other two were stuck and the whole nut and stud came out as one. This was fine, I reinstalled them until the stud bottomed out and then just twisted the nut in the tighten direction until it broke free and then they came right off. PB Blaster helped.
The turbo is currently running on GDE’s hot tune with no codes although, it may need some fine tuning on the VNT control tables. Obviously, if you want more power, its going to require custom tuning. My plan, at least initially, is to max things out and then maybe have industrial injection hone my injectors 20-25% for a conservative 250 hp.
