I got the new HKS Super Sequential BOV v3 Supra kit. So it came with the recirculation fitting as well as a mounting flange. I'll try to take some pictures of it when I can. It is an absolute pain to install. It is obvious it wasn't designed to fit in the Supra with the recirculation fitting at all. I need to get some flexible silicone hose as rubber hose really does not want to bend. Plus I had the TRD shock tower brace installed so that complicated the install even further. All I can say this was the biggest pain to install of anything I ever did. -Gary Bechtold 1997 Toyota Supra Turbo On 5/2/2010 12:00 PM, mkiv-request@mkiv.com wrote: > Today's Topics: > > 1.

I had noticed this about 1.5 year ago and during my inspection of the turbos, I found the #2 turbo had excessive play in the shaft outside the tolerance. After discussing it with Stu Hagen I opted to install a set of hybrids which Stu supplied. During the install I replaced all of the vacuum lines and checked the actuators were working as specified. This unfortunately, did not correct the problem. I got busy with work and didn't get back to it until this week. Now, I've tested almost all of the VSVs except for the EVAP by the pressure tank. The waste gate valve vsv failed all of the tests while the rest were well within specifications. I've ordered a replacement (although I may not keep it since it seems that this valve is bypassed when installing a boost controller). Anyway, while I was waiting I decided to test if this really is the cause of my car's low power development, so I disconnected the hoses from the VSV and took the car for a drive. I found no improvement at all. In fact the boost gauge registers up to 5psi from 4k - 5k rpm and then the power buildup flattens out. The car idles great, there is no unusual engine sound or rough running. Any suggestions on what might be the cause? Also, is there a searchable archive of the mkiv list group? Thanks in advance for your help.

Are you running a cat? Is it clogged? Have you checked your engine's compression? Have you pressure tested your pipes from the turbos to the intake to make sure you don't have a big boost leak? Since you've replaced the turbos, I assume you've inspected all the valves/flappers around the turbos (wastegate, EBV, exhaust, and intake valves) to make sure they are intact and can and do open and close completely. You can wire the actuators open and run the turbos in parallel mode to eliminate the operation of the sequential system as the problem. My first bet would be a big boost leak somewhere, though. Here's my preferred method of pressure testing the intake: All you need is 10 ziplock bags (or a few garbage bags), an appropriate sized tee or two, some extra vacuum hose, an optional pressure gauge, and an air compressor with a nozzle that fits in your vacuum tube. To seal the inlet of the Intake Air Connector and No. 1 Air Tube (See http://www.mkiv.com/manual/manualtt/twin_turbo_replacement/ttr2.JPG) use about 5 ziplock sandwich bags (any sturdy plastic garbage bag layered 5-10 times should work also), cover the Intake Air Connector with them and put the pipe back on to seal it. Also do the same thing on the throttle body with the final large rubber pipe. Then pressurize and monitor with a pressure gauge by teeing into one of the many smaller hoses in the system. I used the return hose for the wastegate VSV, but you can use whatever is convenient. Pump it up to 10 psi or so. If you don't hear anything at that pressure, you probably don't have a significant leak. The list archive can be found at http://mkiv.com/pipermail/mkiv/ and can be searched via Google: http://www.google.com/search?q=site%3Amkiv.com%2Fpipermail%2Fmkiv%2F David On Tue, May 4, 2010 at 8:00 PM, Arif Khan wrote: > Hi guys, > > My 1994 TT has been developing about 50% of the power it used to.

The turbos should be able to overcome that easily. If that leak means the VSV isn't working and is not moving the actuator, that could cause a problem, though... Are you running catalytic converters? Have you inspected them? If your exhaust is clogged for some reason, that would limit your boost. Your intake air filter is not original or something like that, right? Just checking basics... compression test checks out?

The car built up 5-6psi of boost and pulled strong through to 6k rpm. While it didn't feel quite as quick as I remember it, it was certainly much faster and the flat spot is gone. I also noticed that the boost would build up and then drop down to vacuum. Since I didn't have a boost gauge when the car was running normally, I don't know if this is normal. Also, I'm seeing about 20 in. Hg vacuum at about 2500 rpm 2nd gear and 28 in. Hg off throttle. This should be quite healthy. Considering that the EGCV and IACV VSVs are involved in the conversion I would think that one of them is suspect, but both pass the test given in the manual. Any thoughts?

Since then, the car has driven about 600 miles. I am also running a stock air filter box with a new filter. Oil and fuel filters are new as well as the motor oil. Oh, and I've got a RMM 3" downpipe with an HKS Titanium catback exhaust. Lance - I tested the actuator that next to the reed valves and it moves smoothly and under about ~50 mbar of pressure. Since I've had some time to do some testing this week, I did the ttc without involving VSVs (check valve to the actuator) and was able to get boost to go up to 8 psi before it dropped off. Also, I got this level of boost with the WG VSV hoses disconnected to eliminate the chance the WG kicking in. I was hoping to see at least 10 - 12 psi. Could the pressure bottle be suspect? It's the only component of the system I haven't tested as yet. As always, thanks for all the advice and patience.

Be very careful with the WG disconnected. Those hybrids should be able to over boost pretty easily once you remove whatever is causing the restriction. Watch the boost gauge and let off quickly if you see it shooting up past 17-18 psi.

Do you still have stock boost cut in place and working?properly or do you have any form of Boost Cut Controller or Fuel-Cut Defencer or "Free Fuel-Cut Defencer" done?to your Supra?? I ask because without the stock boost cut present and working normally, disabling the wastegate is a bad?idea, especially on pump gas...? I?feel that using the "check valves" method for Parallel/True-Twin Mode doesn't seem like it would be a valid test if there are problems with the actuators and/or VSV's because some or all of the check valves wouldn't?ever be triggered?and couldn't do their intended tasks for your test if the associated VSV's aren't working right so hard wiring the actuators into True-Twin?mode?seems like a much more valid test.? ? I suspect that you probably saw more boost in your Parallel/True-Twin mode "check-valves" test process only?because of?working the #1 turbo harder?due to your disabling of?the wastegate actuator by removing its' vacuum hose rather than getting any boost from the #2 turbo. That doesn't mean anything's wrong with the #2 turbo itself, it just means it probably isn't being added to the mix due to possible sequential system issues. ? Anything's possible but it sounds to me like you're not getting the #2 turbo online fully, or at all really, but you're on a good diagnostic path so far.? ? As David suggested, give the full True-Twin conversion a try but be sure to do it with the wastegate reconnected properly and see what boost you get. Also, try the wastegate with the vacuum line connected through its' VSV like it normally is, then try it?again directly connected between the turbo and the wastegate actuator with the VSV out of the vacuum line?path and see if it makes any difference in boost levels.? I'm just curious what you get... ? ?

Be very careful with the WG disconnected.? Those hybrids should be able to over boost pretty easily once you remove whatever is causing the restriction.? Watch the boost gauge and let off quickly if you see it shooting up past 17-18 psi.

Please go to flicker.com search for inov8tn as a person. Click on the item. The cylindrical piece fits inside and 'locks' inside the loop. It's not apparent where the assembly is mounted or what it does. Both items were found outside the pit where the inlet sock lives. I can't figure out what they do. I think I have an intermittent fuel starvation problem (no boost, mildly increasing EGT) so I tried checking the fuel pressure. It seemed fine when I tested it and the car performed OK that time. So I pulled the fuel pump to see if there was anything that might be blocking the inlet sock. There is a tablespoon or so of fine gravel/course sand in the pit where the sock lives. The sock is pretty stiff so I'm ordering a new one. I'm thinking that I have to drain the tank to get the gravel out. Does anyone know of a clever way to remove the gravel without draining the whole tank (it's about 1/4 full). If I pressed a lump of modeling clay onto the gravel would it stick to it?
