wheres a good place to buy a 60mm gillet diesel sevice off the internet whats a good price thanks

[Richie O]

Direct from them.

[91bluecummins]

r they the cheapest cause i really couldnt find anybody esle that had the gds they all had the high priced htt

What are your plans for the truck? You may be better off saving for an actual turbo upgrade rather than a compressor upgrade.

[91bluecummins]

nothing much just wanted a little more air might get slightly bigger injectors but is the 60mm upgrade worth it can u feel any diference

[ellis93]

You'll see a big difference in the temps on the pyro.
My truck,with stock fuel settings, will make 27 pounds of boost and my egts almost never reach 1200 pulling a heavy load.
IMHO, its well worth its money. It and the 14cm exhaust housing was a major improvement.

If you don't have anything extreme planned for the truck I think the 60mm compressor upgrade would be all you'll need. It will be a marginal upgrade but better than the stock turbo for sure, and it makes quite a lovely whistle as well.

Our very own Richie O has this on his '93 I believe (it's been a long time since I've been able to talk 1st Gen, he may have changed his set up from about a year ago) so he'd be able to tell you more about the turbo from 1st hand experience.

Here's a little video Richie made..

Actually Parker, I just put that turbo on my 92 tow pig a couple months back. I threw a HTT 62/71/14 with a ED drive pressure wastegate on the 93. Putting this turbo on the 92 I went from 18 psi max to 24 psi. The 92 had the 21 cm stock H1C on it and it was a pile of crap. I have the tamper cap still on the 92's pump and can still hit 1300 plus towing. The only mod to the pump is ground stock cone, and high idle screw removed. I would bet I am not over 200 horses and it still gets warm. I even engage the clutch fan on long hills. She is getting plenty of heat soak. I do run it hard when towing, but still for the power I have, it gets to warm. It is better then the stock set up, but just.

[ellis93]

Mr RichieO why is yours getting so hot. Mine doesn't even when I hauled those heavy logs the other day. I toted those a pretty good distants too.
I'm not fooling around about my temps either. Maybe my pumps not fueling as hard as yours or something?

[Richie O]

I have stock timing and stock charge air pipes.

[ellis93]

Recon they make that big a difference?
I do have the M2 pin too.

[Richie O]

Some. Your pryo may read lower with advanced timing too, BUT, the pistons are taking more heat that you don't see on egt. I may be wrong, but common sense says I am not. I had a pro engine builder tell me advancing the timing does lower egt's, but does not add temp to the cyl's. I just can't buy it.

[cmann250]

So if i PLANNED on limiting myself to stock non-intercooled injectors and a tuned pump, would this be all i would need? What kind of EGT drop could i expect?

[Richie O]

Nope, non cooled sticks rock out some heavy fuel on a wound up pump. I am at 300 horses on my 89 with a stock 727 and stock injectors. My S300G won't even cool that. I even still run the original lift pump, gov spring, and fuel cone.

[ellis93]

Ya I'm not buyng the advanced timing not adding to the temps. Correct me if I'm wrong but Advanced timing means that cylinder pressures increase becuase of the amount of charge air and fuel entering and burning in the cylinders. So if that's true then why don't the egts get higher. It seems that it may be one of those bass-ackwards things in life.
