GINNO78 Posted September 29, 2011 Share Posted September 29, 2011 (edited) Ok guys wonder if you can suggest what the problem is When first driving the car the first time I kick it down to bring the second turbo in it does not boost there is no power and no shove from second turbo like something isnt switching? If I kick it down a few times to bring the second turbo in it does eventually fix itself and pulls hard as it should. So im guessing something is sticking...and once given a few blasts of throttle eventually frees up but when left overnight when car is not in use it seems to stick again the following day any ideas?

hodge Posted September 30, 2011 Share Posted September 30, 2011 Sounds like a vac leak. I had the same issue with my blue supra when it was BPU. Check all your vac lines on the turbo side especially the 2 that run from the hard pipes down to the VSVs at the front of the turbos. Mine had a small tear in wasn't noticeable but the split was enough to to have the 2nd turbo intimitent. Quote Link to comment Share on other sites More sharing options...
GINNO78 Posted September 30, 2011 Author Share Posted September 30, 2011 But if this was the case it would do it consistently? Mine only does it when you first drive the car .....after you brought the second turbo in a few times it always works almost like something is sticking as opposed to a VAC leak Quote Link to comment Share on other sites More sharing options...
hodge Posted September 30, 2011 Share Posted September 30, 2011 Check the exhaust gas bypass valve. It's the large actuator type thing under the turbos with a single vac line going to it. Try the car in TTC mode and see how you go. Quote Link to comment Share on other sites More sharing options...
GINNO78 Posted September 30, 2011 Author Share Posted September 30, 2011 Thanks Hodge will do Quote Link to comment Share on other sites More sharing options...
GINNO78 Posted December 25, 2011 Author Share Posted December 25, 2011 Oh this turned out to be a split in the rubber pipe that goes over the top of the engine case its a breather pipe I believe.....after changing this no more issues Quote Link to comment Share on other sites More sharing options...
