carl0s Posted February 4, 2006 Author Share Posted February 4, 2006 I'm not suggesting anybody go ahead and do the job without first getting a continuity-tester (cheap multimeter) on there first though and checking it's the correct resistor. My car is a UK spec and so the ECU may be different to the Jap ones. Link to comment Share on other sites More sharing options...
JohnA Posted February 4, 2006 Share Posted February 4, 2006 Another thing: have you got a boost controller fitted? Because without tapping into the wastegate boost signal mine wouldn't boost AT ALL over stock settings. Link to comment Share on other sites More sharing options...

The car basically has 3" piping near enough straight through from the turbo back to the tailpipe. Link to comment Share on other sites More sharing options...
JohnA Posted February 4, 2006 Share Posted February 4, 2006 That is strange. I too have full decat and 3" downpipe, exhaust is feckin straight too (on the verge of anti-socialism) If you have UK turbos, then you must have the larger wastegate. (my assumption being that all UKSpec engines are the same in this respect) Here's an idea --- have you checked if you have any boost leaks from the hoses around the actuator? They can all get brittle and develop tiny cracks that only leak under full pressure. Link to comment Share on other sites More sharing options...

I have no idea about all the actuators and VSVs et cetera. Link to comment Share on other sites More sharing options...

I have no idea about all the actuators and VSVs et cetera. start looking at the front. http://www.max-boost.co.uk/max-boost/images/supra/hotspot_locations/turbo1_actuator.jpg the thing in the yellow circle is the wastegate actuator. It's got one hose going at the top, one at the bottom. First check that they are OK. Then follow the one at the bottom as it goes to the VSV and verify that is also OK. I'm not sure that you should be going *anywhere* near FCD levels without a boost controller (or a leak emptying the actuator sneakily) Link to comment Share on other sites More sharing options...
carl0s Posted February 4, 2006 Author Share Posted February 4, 2006 ah shit.. completely forgot. I fitted a ball and spring type boost controller ages ago Sorry.. Link to comment Share on other sites More sharing options...
