Replacing the HX35 turbo

[Archive]

I've got a new turbo on the way to replace my ailing HX35 turbo. Does anybody know if the HX40 turbo will bolt up without any modifications to my exhaust system?????

Skag,

The exhaust outlet is 4" on the HX-40. You will need a new downpipe. I'm not sure if you have a 4" exhaust now, but it's best to install one so there will be no restriction.

It will bolt up to the OE exhaust manifold.

I recommmend getting your HX-40 from Joe D or Piers @ BD Power. The turbo comes 'clocked' for the Dodge Ram, includes a 4" down pipe, all gaskets and the wastegate linkage is modified to hook up to the OE Dodge actuator.

Thanks for the reply.
I've got this motor in a boat - see previous post. Anyway, It has a homemade exhaust manifold that mated up to the hx35. You answered my concern - it should match the exhaust manifold. The exhaust pipe I'm not sure of though - sounds like I need to make some changes. If the outlet is larger, I need to get my hands on the piece that mates up to the hx40 - I'll also need a larger clamp. All I need is the part that mates up and is used to clamp and make the turbo seal. I'll weld my exhuast on to that piece - if I can find one - any ideas where I can find one?
Thanks,

Craig

Craig, BD Power has the 4" down pipe and V-Clamp.

I bought header wrap at Summit Racing for my turbo. One 2" X 50' roll is plenty. #ad

Hemi Dart, what would you gain by wrapping the turbo? Reduced underhood heat? I've heard wrapping headers & collectors on gassers helps with exhaust gas scavenging which increases HP and MPG. I would if there would be any similar gains on a turbodiesel?

Vaughn, I read a thread about a year ago that explained the benefits. If I remember, the exhaust cools rapidly after the turbo and slows accordingly. The theory was wrapping the housing and first three feet or so of the dowen pipe would retain some of the heat and thereby keep the speed of the exhaust up reducing the pressure at the outlet of the turbo. I don't know if I am completely sold because there is more to the exhaust system than the 1st 3 feet. Maybe that the sheds some opaque light on the subject.
