Gillett Diesel Turbo Upgrade

Hey everyone, ive done a bit of searching on here and haven't seen alot of feedback for the gillett diesel turbo upgrade. My truck has the mods and sig and of course ill do injectors when i do my turbo upgrade. I'm looking at the 60mm compresor housing with the 6 blade wheel, and possibly a 14cm exhaust side. Anyone have any expierience with this upgrade?(or gillett diesel) I want a little more feedback before i go ahead and get it.

Thanks

6 blade 60mm requires machining while the 8 blade does not. 8 blade surges more and GDS said the 6 was better. Also said $40 to do the machine work.

Just got my 6 blade in. Way better than the 8. The 8 surges quite a bit with an auto and the 6 has not surged yet. My advice would be to not get the 8 under any circumstances. Hit 50 psi wot with it. As well the 6 blade is supposed to flow significantly more air.

Steve Wright at Gillett was very helpful. Tell him Kevin from Mb sends his best.

The face plate that the compressor wheel sits recessed in.

I put a 60mm compressor upgrade on mine when I built my 5x.012 injectors. It definately helped, but not quite as much as I had hoped. Also its just pushing alot of hot air above 42ish lbs of boost. 14cm exhaust housing would be a nice addition.
In my opinion you end up with alot of dollars invested in a turbo that still has a weak shaft with a larger wheel on the end. Dont bark it too much or you'll be slinging parts. Something i would like to try is putting the 16cm nongated housing off a wh1c on the exhaust side and see how that helps.

I have the GDS 60mm wheel on my secondary with a non-gated 12cm housing. Can't beat the quality and sure makes for a sweet spooling set of twins!

Yep. It's essentially a 35/40 hybrid kit for all intents and purposes.
