Hi everyone! After installing the intercooler setup from a 1985 245 Turbo that was equipped from the factory what do I need for my '83? I printed the information available from Turbobricks that shows you how but somehow I am missing out on some specifics - most notably concerning the vaccuum lines. Do I need to change the charge air switch ( overboost? )on the firewall and do I use the solenoid valve that was mounted on the '85's right inner fender? There was also a valve of sorts mounted near the brake booster with a electrical plug on one end and a vaccuum line on the other, do I need it? Since dismantling the '85 I forgot where alot of the lines went! Trying to locate info at the moment from Volvo. Also there are two holes in the intake pipe between the air box and turbo - one for crankcase ventilation and the other accepts a smaller vaccuum line - any ideas? I hope I am not asking too much it's just that I am new to turbocharged 240's and this is my first time installing an intercooler. I noticed my warm up regulator ( on the block near the distributor ) has two vaccuum lines on the body and the one on the '85 has none - which can I use or does it matter? There is another vaccuum switch inside the car near the brake pedal - do I need to change it? Is it safe to re route the vaccuum line from the turbo itself - the Turbobricks article says to plug the 90 degree connector on the housing - is the line going across the radiator shroud from the intercooler pipe plugged into the line going to the wastegate actuator and is this a good way to increase boost or is there a better way - such as grounding terminal 11 on the ECU to enrichen the mixture under boost ( or both ). I would very much appreciate any help on this matter and my last question is - how do I install a Compressor Bypass Valve? (CBV). Thanks every and anyone for your time!
