On a stock truck the HX35 and 12cm housing should cool EGT's slightly. Depending on your truck year you should be seeing 14-20psi stock. The HX35 will provide more air, and as long as you don't get it out of its map (which you won't on a stock truck) you should be fine. And the 12cm housing will help spoolup without negative effects on a stock truck.

 

I did thid swap a few months ago. You need to shorten the downpipe about 1 1/4". You also need to swap the oil line fitting over from the H1C. The spool speed is wicked as well. For extra fun pick up a boost elbow for 94 up trucks from TST, I think it changes the pressure to about 32 PSI out of the box.

 

As Gman said, EGT will drop due to the extra boost, so you won't melt anything. You will get a lot more bottom end out of the '92. You can't really do much for the bottom end on the '93 because the torque converter doesn't stall until around 1800 RPM. Change to a low stall converter and the turbo will make a big difference.

 

I may try this on the 92' if I can come up with a good used turbo. I like this idea more than the idea of adding fuel. The 92' sometimes grosses as high as the upper 30's combined weight, so I really got to be carefull. The 92' doesn't ever pull much more than the 24' stock trailer which it does decent with but that is only 8,000-10,000lbs at the most when it has a couple horses or cows in it. It needs a better converter awful bad, but the tranny that's in it is holding together real well, once it goes south someday I am gonna get a Dave Goerand tranny and converter for it and then may consider the turbo upgrade?

I really like the idea of this, more power without pouring more coal to it. I don't need much, but a little more would be nice, especially on the 92' as it gets worked pretty hard.
