Need the correct turbo vacuum line rounting: 88 TurboCOupe, just installed a T3 using stock intercooler and homemade boost controller. Having trouble figuring out what to do with the lines going to the IC. Do I keep the stock line coming from the vac. tree on the IC? What about the other nipple on the IC?
I primed the system with the motor still on the stand just to verify oil circulation. I primed it again before starting it. It looks like my ISC is working, no engine codes.
Motor is installed and I fired it up a couple times. Seems to have a hard time keeping an idle at first. I unplugged the IAC while running and nothing happend. Also top end is ticking, maybe I need to adjust my rocker arms some more, pics to come later.
I've talked with Summit and Comp. Summit came up with these: 35-310-8, 35-308-8, 35-351-8 http://www.summitracing.com/compare.aspx , but talking with them the second time the guy said to stay under 0.500 lift with my engine/head combo, there may not be enough clearance. Also he said the 35-512-8 cam or E303 would work with a stock converter. Who's right?
87 Turbocoupe gives me code 42, O2 sensor has fluctuating voltage like it should. The idle will randomly stay high, 1500-200rpm. Tried multiple idle solenoids. I replaced O2 this year. EGR vacuum line is disconnected and capped. Code 25 also comes up for knock sensor, I wouldn't think that would matter.
