I'm doing my best to try and get my new turbo installed, started last week and only got things disassembled before I ran out of energy.  I got back to it today and am almost done but I was unable to get the down pipe installed.  I was hoping it would go right in as I am replacing a DEP pipe(HY35) with another DEP pipe(HX40).  It looks like I am gonna have to beat the firewall or the pipe to get it to fit.  Should I just take turns hammering on both until it fits?

I've never seen anyone have to beat a firewall. Are you sure you have the right pipe?

I honestly don't know, the turbo, manifold and down pipe were a package deal so I assumed it would all bolt together and frankly it's been a PITA.  I know I got the right turbo, I double checked the part I got with my invoice and the numbers match.  I ended up pinging the down pipe until it fit, didn't take a whole lot thankfully.  I finally got to take it for a spin and I'm amazed at how different the exhaust note is, much deeper.  I assume those injectors will cure the fact that now I don't build boost as quickly as before and the truck smokes even more.   

Smoke typically a sign of lack of timing. I barely smoke still 150 HP injectors. I generate a small cloud during launch but clears up completely. I know you've tried Quadzilla and backed out. Honestly it would be the best solution.

I figured it was my injectors being worn out, I believe they are original with 250k miles.   The truck has been smoking more than usual the last year along with a decrease in mpg so I figured it was time to change them.  I would guess they are just pissing fuel as opposed to atomizing it.  

Typically when injectors wear past 100k miles the pop pressure falls and the droplets get bigger. Again needing more timing to vaporize, and go BANG! Injectors are a wearable item and should be replaced every 100k miles to be optimal.

So out of curiosity I took another look at my down pipe and googled the part number on it.  It is the right part number but the pics I found were not the same.  All the pics I saw had a pipe with a sharp bend right after the flange, my pipe goes straight out towards the firewall before bending down to the frame.   I think I may have gotten an incorrectly labeled pipe,  working in the auto parts world I know that can happen quite often.  I ordered a new down pipe from another vendor incase DAP has more than one incorrect unit.  If the new one I get is different I will call and let DAP know.  I paid a little extra for shipping so it hopefully arrives by Saturday so I can get it swapped in for the trip to your place. 

I do agree with mike. My injectors have over 100k truck still runs okay but not as good as it used to and is smoking different than it used to.

 

I guess im going to have to dig to see what turbo you went with

After doing injectors and head studs for @Sycostang67 I seen how close the his exhaust pipe is to the firewall. Part of it is he opted for true 4 inch pipe. Not like typically 3 to 4 kits.

The other down pipe I ordered looks the same, I will try and see if it fits differently though.
