HX35 on my truck.

Any custom fit goodies I have to worry about? I get the downpipe with the hx35 too. The only issue I may have as far as I can see, is my pacbrake.

This kinda what a wastegated housing with a PacBrake looks like in a 1st gen. It's tight:

There's no more than about an inch of clearance to the heater box with the pipe dropping almost straight down from the Pacbrake. Later I finished the job with a full 4" model:

You will need to get the DP from Pacbrake (3") if you want it to bolt up to the bellhousing, or make a custom one like I did.

Can I put a non wastegate housing on the hx35? I mean, I have a 16cm housing already, will it work on the hx turbo?

[Ace]

Then it would probably be straight swap with your existing DP. You do have the Pacbrake presently installed, right?

[dodgetkboy78]

Yeah, it's been there for years....... But can I put my 16cm non wastegte housing on the hx35?

[Philip]

The H1C and the HX35 use the same exhaust housings. If you don't want to mess with the WG'd housing just use the one you have installed.

[dodgetkboy78]

Awesome! It wont hurt the performance of the HX at all will it?

[Philip]

It will not hurt performance one bit and it also means you don't have to rework any of the exhaust.

Going to the HX from a H1 you will see a small drop in boost. Normaly it is around 2 PSI. But the EGt's will drop some at WOT. On my truck when I did the HX35 swap I had a 25 degree drop at WOT.

Switching to a 24 valve air horn or a set of cool tubz's will give you around a 50 degree drop in EGT's at WOT. I think of a HX35 as a minor upgrade.

[dodgetkboy78]

How is a HX a upgrade if I lose boost? I can lose 50F off the egt from backing off from 38-36psi.....................your starting to give me second thoughts here............I have cooler tubes already.

[Philip]

Going to a bigger turbo you almost always loose some boost. In the holset line figure 2 PSI for each step to the larger turbo.

Right now with your truck at 38 PSI your about 15 PSI over the map range of a H1C. You making a lot of heat to build to that PSI. The HX35 has a map range of 35 PSI.You will be getting a cooler more dense intake charge.

So don't worry about a small loose of boost. Your looking for a cooler intake charge.

[dodgetkboy78]

Right-O.....

I am also thinking of getting rid of the POD's and getting some 370's.
