ho turbo vs standard output turbo.

Does anyone know if the HO turbo is different than the 235hp 24valve turbo? I was looking through the service manual and the compression ratio is different. Just curious.

Turbos are exactly the same-- except for the 01-02 trucks with auto transmissions, which have the HY35.

The only difference between the 235hp and 245hp turbos in a manual trans truck is the amount of boost the ECM will allow before defueling.

You can not intermix but you can bolt up the hx very easily

How much of an improvment would that make and is the hx on standard transmission models?

The HX was standard on 98.5-2000 on all and then 2001-2002 on the 6 speeds.

There is nothing wrong with an HX40 as long as you treat them right. Keep em at 40psi and under, and no barking, and they will live just fine, and support a decent bit of power for their size.

You can break any turbo shaft, just surge it hard enough. Most HX-40 die on nos trucks or guy pulling 50 psi and bark the turbo. You can break the HX-35 as well. The HX-40 shafts are cheap, same goes for the rebuild kit. You just have to balance it to get it to work right. They aren't perfect and indestructable. I've ran a few so I know that they work. Just don't mess with the wastegate on any turbo unless you know what you are doing. They are a just a larger turbo that lots people have abused and have been given a bad rap. They are one of the cheapest turbo going, so why not use it.

Has anyone put one of those (HE351C)on a 2nd gen 24 valve? If it fits would it help to be able to fuel it up? Or, would the HX35 be better?

The HE351cw is a bigger and better turbo than the HX35. The HX35 chokes out around 400 hp, the HE351 stops around 500 hp. Unless you have a 3rd gen, the most recorded HP to date for the HE351 fuel only is 572 hp.

Although the HE351 has a 9cm housing, it has the same sized exhaust turbine wheel as the HX35 with 12cm housing. What this means is the HE pushes more air but flows similar on the exhaust side.
