HOSES AND VACUUM LINES TO BE REMOVED:
1. Original h2o coolant lines to stock twins (2) they are located on the aluminum 90 degree elbow that the upper radiator hose connects to. Take the time to take it off and have both nipples removed and tig welded shut.
2.Remove the pressure tank under the intake manifold and all vacuum lines to it you do not need to worry about the wiring plugs that hook up to the tank just tape them up and they will not cause a check engine light.
3. Remove the EGR that is mounted to the back of the intake manifold and the sensor mounted on TOP off the manifold next to the EGR. There is a plug that goes to the Metal EGR sensor that you will need to install a 10k resistor in (wiring harness side) this will clear the code and keep your check engine light off. Pay attention to what vacuum lines feed the EGR items and you will see what needs to be capped or plugged off.**NOTE** you may want to purchase the EGR block off plates for the mod. This mod does NOT have to be done but it makes things cleaner and gets rid of extra vacuum lines and most importantly it stops hot exhaust from recirculating into the intake a causing lean conditions in the #5 and #6 cylinders. After you get the EGR off you will see 3 vacuum nipples sticking out the back of the manifold you will use these for future vacuum sources. (ex. I used one for the BOV, wastegate, and fuel pressure regulator)
ORIGINAL OIL FEED LINES TO STOCK TWINS
4. I Used the original bolt that holds the REAR turbo feed line to the block and put approx. 3 copper washers on the bolt then a big nut then 3 more copper washers to plug off the rear turbo feed line that you will not be using anymore. For the FRONT feed I did the same washer/nut setup but I drilled a hole in the center of the bolt head and tapped it to an 1/8" pipe thread so I could use an 1/8" pipe to -4 line to feed my single turbo.
COOLANT LINE RELOCATION
5. I would not relocate anything until the car is running and you see what obviously can be done. I would never take off the oil cooler unless your car is used for drag racing only. Just block off the 2 nipples on upper radiator hose elbow as listed above.
OIL RETURN PIPE IN OIL PAN
6. I simply took it off the pan and welded a -10 male fitting in it which you will connect with a hose to the bottom return of your new turbo.
***NOTE FOR OBDII CARS*** you will need to put resistors on the vsv connections to keep from throwing codes. Sorry but you will need to do a search for pics, locations, resistor size and tips
THIS IS MOST OF THE INFO YOU WILL NEED AND AS YOU START INTO THE PROJECT THINGS WILL MAKE MORE SENSE
Hope this help a little for some of you beginners
Good luck,
Jason
