My cheap turbo 60 mm upgrade sound comparison

Postby Richie O » Sat Mar 14, 2009 9:13 pm

Here is a vid clip of before and after GDS 60 mm upgrade. Just a quick stationary open turbo clip. I have no before or after results. Have not driven truck more then a mile since I got it. Project 93 rust hole. :lol:

GDS sells the 60 MM wheel and housing for 225 plus shipping. The only reason I bought it was because I had a good spare H1C with the 16cm on it. I upgraded that one and kept the stocker complete for a good spare.

Big difference. 6 is better. That's the Stage IV wheel. The wheel is deeper, that's why if you get an HTT they give you a backing plate and GDS has you machine your old one. The compressor housing is different too. Had them both and compared them. ;)

Rich, ha ha! Sissy turbo! :tongue:

It fits stock backing plate. No need for turning. The cfm difference is supposed to be real close. The Htt is better but for me the cost difference was not worth it.

GDS has since changed that. There is no more need to machine the backplate. Supposedly, there is a very small difference between how much they flow. Not enough difference for me to cough up the extra $200 or so. Of course, when you bought it, I'm sure it was a different story, not trying to knock ya.

I may have asked you before, but did you have the turbo balanced after you did the upgrade?

Vendor doesn't matter. Stage III is the same from either. The difference in the IV is the backing plate. HTT sends you one, GDS has you adjust yours. It was a $100 difference, I paid it because I wanted to bolt it on and go. Not find a machine shop and wonder if they did it right.
Parker, it was a couple years ago.

Balanced? Yup, spin balanced it myself! I started the truck, it spun and didn't make any funny noises, so it was good. ;)

Me balance?? No. If she blows she blows. 8) The intercooler will catch the big chunks,,,, I hope. :shock: I had a truck driver hand me a blown up exhaust wheel. It was broken in half and he said it actually came out his strait pipe exhaust. He was proud.

Thats funny Pete. I have not seen on GDS any mention of diffrent kits other then the different size wheels. Not listed as stage 3 or 4. Maybe they have changed.

Should have seen the one I pulled off my buddys loader before christmas. The turbo was bad, and blowing oil. They ran it back from the site they were plowing snow at. It was about 8-10 miles. I got the elbow off the outlet, and looked in to see how bad it was. It was bad. No wheel, no shaft. No wonder it was blowing oil! :lol:
It had a 4" pipe about 2 foot long with a spout on it. The spout had a hole rotted in it. I'm sure this didn't help any. ;)
