nickgarthright Posted March 8, 2015 Share Posted March 8, 2015 Hi I was wondering where the two circled parts are supposed to go? Quote Link to comment Share on other sites More sharing options...
theczechone Posted March 9, 2015 Share Posted March 9, 2015 The re-circulation valve connection should be connected to the low pressure inlet into the compressor The cam breathers are usually just connected across to equalize the pressure in both sides. People usually use these to setup their oil catch cans. Quote Link to comment Share on other sites More sharing options...

deuce8ernerozero Posted March 9, 2015 Share Posted March 9, 2015 The compressor is the cold side of the turbocharger. Quote Link to comment Share on other sites More sharing options...
nickgarthright Posted March 9, 2015 Author Share Posted March 9, 2015 Thanks! Do the cam breathers go there too? Quote Link to comment Share on other sites More sharing options...
900ss Posted March 9, 2015 Share Posted March 9, 2015 Via the air intake to the turbo or just vent to a separate oil catch can mounted neatly somewhere on the inner wing Quote Link to comment Share on other sites More sharing options...
nickgarthright Posted March 9, 2015 Author Share Posted March 9, 2015 If the cam breathers are vented in the intake after the afm but before the turbo, couldn't oil spray into there? That seems problematic. Quote Link to comment Share on other sites More sharing options...
900ss Posted March 9, 2015 Share Posted March 9, 2015 Will be fine unless the engine is knackered, in which case you already have a problem lol Quote Link to comment Share on other sites More sharing options...

mtnickel Posted March 15, 2015 Share Posted March 15, 2015 The rubber intake boot that attaches to the turbo has 2 inlets for both of these connections. There was however another hard metal pipe that brings the connections closer, but I suppose you could somehow do it with a tube. As a note, if you're using the stock ECU system with the MAF sensor, then it's important that you route these back to a location before the turbo, but after the MAF. The Bypass valve will be slightly open during idle and higher vacuum, this results in an air leak where unmetered air gets into the engine (unmetered meaning air that hasn't flowed through the MAF sensor). This will in turn cause the engine to run lean. Opposite happens when it operates as intended (to bleed off turbo air pressure), the turbo sucks up tonnes of air which the MAF senses, but then it's routed back out to the atmosphere instead of the engine. As such the ECU triggers the injectors to fire way more than is needed resulting in a high rich condition (often can cause engine to cough, burble, flames out back, etc). Ricers always route them to atmosphere for the ricer sound only to find strange drivability problems between shifts. The Crankcase vent system is also part of the metered air system as there is a hose and valve connected on the side closest to the intake manifold that leads into the intake manifold that is intended to constantly cycle the air out of the crankcase. However if you convert to a MAP (manifold air pressure) aftermarket ecu solution, none of the above is a problem. If you need the stock rubber intake hose, i have one, however I don't actually have the stock hard pipes anymore as i scavenged bends and such to lead to my custom hard pipe intake. Final note, the stock rubber inlet hoses are probably only good to about 280-300hp as higher flows can cause them to suck shut. There are some DIY's to reinforce them however. Good luck with the build! Quote Link to comment Share on other sites More sharing options...
nickgarthright Posted March 17, 2015 Author Share Posted March 17, 2015 Thanks for helping clarify! I ended up just making a makeshift hose from each to the intake (before turbo, after afm). If it develops problems I will take you up on your offer! Quote Link to comment Share on other sites More sharing options...
