Yeah that's definitely on the agenda. All the wiring harnesses in the valley area need cleaned up real good. How do you guys suggest cleaning them up?

 

Simple green and water.

 

Well I I got the old up pipes out today and got the new ones loosely mounted in there. I also removed the old leaky turbo pedestal and did a little cleaning in the valley. All of that took me just over two hours. I was really suprised how easy it was. The old ones pretty much fell apart once I took them loose from the exhaust manifolds. When I took the new Dormans out of the box, I mocked them together outside the truck and sure enough the four bolts that secure them to the baby's butt were about 1/4" too long. A short trip to the grinder had them shortened to the proper length. I pretty much followed the directions that I downloaded from Riff Raff's sight and assembled the passenger side up pipe to the baby's butt and inserted it from the top. Then I pushed the driver side pipe up from the bottom and got everything loosely mounted up. It looks like the bolts securing the pipes to the baby's butt will be next to impossible to get to once the turbo goes back in, especially the passenger side, I think I can get to the driver's side from under the truck. Would it be okay to go ahead and tighten the bolts to the baby's butt up, leaving the bolts to the exhaust manifolds loose until everything is back in or will that make it harder to mate the baby's butt to the turbo? Here's a pic of the new pipes setting in the truck waiting for the new turbo pedestal and a pic of my leaky EBPV turbo pedestal.

 

Hardest part is getting the collector to match up to the exhaust housing on the turbo. Once you get the turbo in the valley, you can't see anything anymore and have to go by feel. Makes it tought to get the clamp on there. Just be very patient and climb way up in there and hug that turbo!

 

Do the up pipe bolts need to be torqued to any specific ft lbs or just good and tight? Not that I could get a torque wrench in there anyway! Lol

 

Yeah, it's a catch 22. They do have a torque spec, but it isn't much. It amounts to good-n-tight since you can't get a wrench in there while engine is in the truck. 18-20 ft pounds l think. I'm mobile right now, so I can't look it up.

 

With the bellow up pipes since the flange is welded to pipe you can tighten the top bolts to baby's butt. But leave the lower to exhaust manifold loose until the turbo is installed.

 

That's what I was hoping to hear!

 

You can, but I didn't torq anything till I got it back together. There is a torq spec., but I can't find it. Twenty # sound right. Your going to love the difference. These IN style pipes are great. At least the ones from Clay made a big difference. Mine didn'
t have a lot of soot but fell apart in my hands when taking them apart.

Yeah I'm expecting a huge improvement. My egt's were running around 800 while running about 75 mph on the interstate, my truck has 4:10 gears so that's about 2400 rpm's, I'm thinking the egt's should be more around 600 at that speed. I'm betting these new up pipes help that. My old ones were awful, which made them really easy to get out. On another note, my new non EBPV outlet housing came in today. I took the old one off and then had a thought before installing the new one. Should I or can I clean this up in there? It seems that with the non EBPV housing, it should flow alot better. Seems to me that valve in the stock housing would restrict it quite a bit.

 

Mine didn't look that bad. Is yours a 93 turbo? How much boost were you making before? If 93 you have smaller injectors then we have unless you changed them.

 

My truck is a 2000 with the stock turbo so I'm assuming a GTP38? I'm pretty sure it has AD injectors.

 

I didn't bother cleaning the inside of the exhaust housing. It will look exactly the same in a week...

 

Well I got it all done today, including new pedestal and outlet housing. The install wasn't too bad, the babys butt lined right up, getting the clamp back on was the hardest part of that. We had one problem with one of the nuts in the flange at the passenger side manifold. It seemed cross threaded and it took forever tks get it and the bolt separated, turns out the hole in the nut was oval shaped instead of round. Used one of the nuts from the old pipes and back in business. All I can say is wow! I never realized how loud my truck was with the old up pipes, it don't sound like the same truck now. Took it for a drive and hit 25 pounds of boost without even getting on it! Well worth the money and effort! Thanks for all the help guys!

 

You have the same perma-grin I have now! I, too, was very surprised how loud my truck was...and I never realized it. Lots of boost, and nice and quiet. If you can do up-pipes and everything that went with it, you can do most anything on your truck.
