I'm running my stock hx35 on my 97 12v. I've took the fuel plate out and put in a 3k gsk and boost elbow. The truck is running pretty good and I have to replace the clutch before I do anything else, but I feel like the turbo is being a hindrance. I've got it set up so that it doesn't smoke much and egts aren't to bad, but I can easily hit 36-38 psi of boost. According to a previous post 40 is max that you want to push this turbo. Would the 3.5 inch boost tube and intake help? What do you think is the best towing turbo? I tow almost daily anywhere from 5000 to 20000 lbs. I've got the bd supermax on my dura max and it made a world of difference. I was looking at the bd super b or the cpp 62/65 12.

 

Of the two you listed any 62/65/12 would be a good choice for what your after. Another cheaper option would be a good he351, would have to redo a little bit of intake piping and the exhaust piping to make it work tho.

 

Redoing the piping wouldn't be a big thing. I already built the exhaust once. I had been reading about the he351 on here also. I think I can come up with one of them. What are we talking about for spooling, egt control, and peak boost pressure? By how much will it out perform the hx35?

 

I found a video of an he351 vgt on a 24 valve. Would this work on the 12v as well? It had a toggle switch for the exhaust brake. That would be nice when towing.

 

Yes it would work on a 12v also just requires some fab work to make it work. The he351 would spool like a stock hx35 but with more top end.

 

Sounds good. What about the 3.5 inch intercooler line and intake?

 

Another question, if you were to run an he351 vgt on a 12v could you run a pacbrake load leash? Would it work? Why or why not?

 

isnt the pac brake made to work with the 24v head? im not sure how you could put it on a 12v
