    I have the JDM 2000 Legacy and it looks the same. A few years ago my primary turbo went bad and caused the car to smoke excessively so my mechanic disconnected the oil line and I was able to drive the car without any smoking (low power) until the replacement turbo arrived.

    I own one of these, great car. Got it tuned by Kiddo Racing.. and virtually eliminated VOD, and improved mileage and performance significantly. Exhaust would be nice but not real necessary. Only thing with BE5’s are the rubbish headlights. Recommend factory low beam HID’s from Japan and a light bar behind grill for high beam 👍🏻

    Currently rebuilding engine in a 1997 Legacy GTB - block and heads currently at workshop getting skimmed, rehoned and cleaned up. This is my second one i am rebuilding, can find video of me starting my RSK B4 from several years ago on my channel. Will update once i have more info. But the vacuum pipes are a bloody nightmare especially if you don't mark up which one goes where. Would be interested to find someone who can tune the ECU to limit the valley of death - would be good.

    when changing out the secondary turbo actuator, how do you preload the seconday turbo actuator? do you set it to 3 full trun revolutonand then pull it on? or just adjust it till it fit without any pull? hope you understand what im asking.

      Could it be seized up? I read a story where someone bought a GTB off an old dude who obvs never revved it, The 2nd turbo was seized but eventually freed after a bit of frantic driving. Good Luck!

      Now that I look at it, I think the car is retarding the timing when the second turbo kicks in. Because the car starts bucking in after 4500 rpm.@@stuartmccloud307

      Can't speak for their systems, but 2.5 inch dump pipes into a 3 inch pipe after a y join is generally said to be the most effective sizing, and it's what has been put on my car by a PO and it runs well. Could even improve on the design of the one in my car by putting a flange on the primary or secondary pipe near the y join so either downpipe can be removed separately, so that you don't have to be on a lift to remove the one entire piece from the car.

    This car on factory Australia tune over 5 years that i've had it had almost destroyed itself seemingly, at this point i'm fighting at approx 166.xxxk/s is idle shudder which seems to happen when i turn any electrics on, at this point i've repleaced cam sensor, replaced the battery, checked output on alternator, ( had to replace the turbo actuator on the 2nd turbo-not the cause of problem but -because of the stock aus tune it seems to blow out the diaphram- while i'm thinking about making it vacuum instead of pressurising to open the door.) back on original problem i've yet to investigate a fueling problem wether the fuel pump is dying and starving the motor or filter is simply blocked, i have other information as to how and when the problem started - literally car off car on.

    • @groadoswaggins
      @groadoswaggins 3 года назад

      I know this is long past, but if anyone is looking at this, I had this problem and it turned out to be the alternator. Specifically something internal in it (I was told the regulator? is inbuilt) and it malfunctions, so even though it looks like it's charging at correct volts, it's not putting out enough (amps?) to run the air-conditioning and fans (and/or lights) and the spark at the same time. ECM lights up and it throws non-firing cylinder, or bad injector codes as well. Tends to run better when you spin up the revs but if you turn off everything electric and it runs better at idle, this might be it. Hope this helps anyone looking.

    @twinblitzen356scroll 7 лет назад

    I have a 2001 GTB, the Blitzen model, automatic (tiptronic). Since I imported it from the Japan, I've had code 66 error, I have checked all hoses for leaks and I haven't found any leaks, cleaned the driver's side solenoid properly and visually checked it and seems fine but still the car throws code 66 and engine ECL comes on, 7/8 times out of 10. Engine kind of stalls/hiccups and secondary turbo will not boost. Sometimes it does come on and car boosts well both in the primary stage and secondary stage. Don't know what to check next. I haven't checked/cleaned the passenger side solenoid yet or under the air - intake area. I have noticed the air intake fins slightly damaged on the side (less than 1 cm) and the big actuator on secondary turbo rattles a bit at idle speed but stops when you hold its arm that opens and closes the valve connecting to the exhaust system. Help is appreciated.

The engine in my partners 2000 model b4 seized so I swapped engines and everything is working fine and drives fine but the primary turbo is not creating boost, no low end power, and throws fault code 66 when are 3500-4000rpm. could this be anything to do with vacuum lines or seeing as the primary doesn't have many vacuum connection could it be a sticky/stuck Wastegate?
