note: A regular valve maxes out around 18-20psi of boost. You can remove the spring and strech it out and then re-install.
PN: 8581 90 degree 2.5" I.D.
PN: 8011 90 and 45 degree 2.5" I.D.
PN: ???? 90 and 35 degree 2.5" I.D. good for comming right out of the turbo.
Note General Assembly:
1. None of the stock NPT/Tube adapters are used.
2. All the NPT ( pipe ) to AN adapters are Male to Male.
Oil Feed Line
First you have one of 2 choices:
1. Do not use the port on the sending hex for the stock oil feed line. Plug it up and use one of the other NPT 1/8" holes
2. Use Aeroquip part #FCM2931 S.A.E 37 degree Male Flare (-4 AN)to 42 degree Inverted flare (1/2-20 brake thread) adapter to use the factory oil feed line port.
Note: I used the TFE brake line because it is pre-made, has the correct length, and has the correct I.D.
(Qty 2) Straight -04 AN to 1/8" NPT Male Adapters
(Qty 1) 24" -04 AN TFE brake line with a 90 degree and Straight hose end.
Assembly: Thread the adapters into the turbo and sending hex. The 90 degree end of the hose connects on the turbo. It should clear the wastegate rod.
Coolant Feed Line
(Qty 1) 45 degree -06 AN to 1/4" NPT Male Elbow Adapter
(Qty 1) 45 degree -06 AN to 3/8" NPT Male Elbow Adapter
(Qty 2) Straight -06 AN Hose Ends
(Qty 1) 12" -06 AN Hose. Cut to your required length. Mine was 10.5"
Assembly: Thread 1/4" NPT adapter into block. Make sure the adapter is parallel with the crank or pointing up slightly so it can clear the power steering bracket. Obviously the 3/8" NPT threads into the turbocharger.
Warrning: Construction of the -6 Aeroquip hose is a complete BITCH. Step #2 is the most difficult ( see below )
Coolant Return Line
Note: I run my return line around the wastegate actuator. You may need 24" or more of hose.
Note: To install the AN to NPT Adapter on the turbo, you will have to remove the impeller housing.
(Qty 1) Straight -08 AN to 3/8" NPT Male Adapter
(Qty 1) 90 degree -08 AN to 3/8" NPT Male Elbow Adapter
(Qty 1) Straight -08 AN Hose End
(Qty 1) 90 degree -08 AN Hose End
(Qty 1) 24" (or more possibly) -08 AN Hose. Cut to required length.
Assembly: Install Straight adapter at the stock location in the head. Connect the straight end of the hose there. See PICTURE. Thread the 90 degree adapter into the turbochager. You will have to remove the impeller housing to do this. Make sure the 90 degree adapter is pointing straight up. Connect the 90 degree end of the hose to the adapter and point it around the wastegate actuator ( parallel with the crank ). See PICTURE.
These are Assembly Instructions for Aeroquip hose from a Pegasus Racing catalog
1
Screw the hacksaw and use a dremel or some other high speed cutting disc / tool.
2
THIS IS THE BITCH OF IT. After cutting the hose you only have 2 or 3 attempts to install the Socket. The -8 hose was easier.
3
4
5
The hose is so hard to push in, it does not push out when threading the nipple.
6
You REALLY have to torque the hell out of the nipple to get 0.031" or smaller. Use lots of tape or the proper AN tools. The Aluminum hose ends are very soft.
7
WHATEVER, The work required to thread in the nipple is many more times the clamping force on ANY of the coolant or oil lines. Oh NO, But the coolant lines may see 16psi of pressure! Again, Whatever, These hoses were designed to handle 1000psi.
Can you tell I didn't have much fun assembling the hoses? LOL Really, the -8 AN hose wasn't that bad, the -6 was wicked.
Well, I decided to cut the down pipe right before the cat. I attached a fabricated 2.5" almost mandrel exhaust that dumps out right before the rear axle. Major improvement in performance! Note the stainless bolts I bent and welded as hangers!
