I'm trying to complete the install on my new 38r. The problem I have is with the new 4" intake tube. It's too long to allow the CCV coupler to mount.

When I get everything in place, the intake tube extends about 1/4" past the bracket. Due to it's large size, I can't get it all to fit right causing everything to be "off" on alignment.

Has anyone else had this issue and what did you do to fix it?

2nd Question:

The x pipe is also off just a little bit. The babies butt and the exhaust down tube both line up great. The two hold down bolts went in without issue and when I did my test run, I didn't have any leaks where the turbo meet the pedestal.

The tube has more mass then the stock turbo, but with the hard parts mated up fine, I'm having issues with the easy parts. (Intake & X-Pipe).

Any tips or suggestions I might be missing?

 

I had this issue aswell. You defiantly aren't the first. For the first one I ever did, i trimmed the end going to the CCV coupling which worked, but don't trim too

much. The second one, i didn't need to trim, but was forced and somehow I got the screws to line up. Wasn't easy, and sadly it never I'll be. Good luck!




For your second question, if everything lined up as it should have, you should be good. Hooking the up pipes back is always a PITA. The only place that should


be bigger in terms of mounting, is the ported housing on the 38r with that infamous boot.

 

I trimed mine.

 

Mine was just the right length when everything was fully seated - but getting the tube fully seated was the challenge. I had to "form" (bend) the bracket to fit everything properly, and make sure the two hold-down nuts are down tight.

As for the collector, I have IH bellowed up pipes. This makes everything more flexible for easier connection. Even with that, the first V-band had an "issue" with the installer... so I had to order another one from Riffraff diesel to replace it.

 

When trims were needed, which end did you trim? From the turbo side or the filter side?

 

INSTALL... CHECK!

I'm so very happy. It took me some time but I have everything together. Getting the x-pipe connected to the turbo was hard and when it finally clicked together I was relieved.

The 4" turbo inlet was another issue. Here is what I did in the event someone is having issues installing their 38r.

Mount the CCV coupler to the mount. I then positioned the Garrett 4" tube in place to see if it would need to be trimmed. While doing that, I was able to get the turbo side in place. By putting my hand through the CCV coupler, I was able to get the front side on too. Tightened down the clamps and attached the AIS side.

I was good to go. I checked for leaks and found none. Fired up the truck and took it for a spin. The 38r maintains 5psi just driving down the road at 70 mph whereas stock would only show 3psi.

When I get on it, I'm pushing 17psi with ease and considering I don't like to go fast in a 7500lb truck, I know there is more on the skinny peddle when I need it.

I'll keep running and see how the number compare.

Thanks everyone!
