Hi I need help,
I have been researching and tinkering with my rb26 and am having trouble locating the rear vacuum line. My engine was transplanted so were kinda trying to figure things out.
I have found the old by pass line and transfered it to my blow off valve, (sard r2d2) which wont open.
Im running an AEM ECU with map, AIT, and boost control. I noticed that the shop that tuned the car used the fuel pressure vacuum to run the MAP, boost gauge, FPR, and used the charcoal canister vacuum to run the EBC.
now following this thread I tried to locate the old boost line behind the head and upon inspecting finding it It had no vacuum. I traced it further to the throttle side and also no vacuum. I think i need to pull down the throttle body to get a closer look but its a real big job and Im not to keen to do it.
How do I locate the rear vacuum line source or stock wastegate vacuum source?
thank you!
