  1. I've been reading a VERY old thread on this concerning 6 supies doing similar things, and Chris, you mention the EBV or the EBV VSV being a possible culprit? if the TTC mod takes the IACV and EGCV vsv's out of play, and the first turbo vsv is bypassed or seems ok... am I correct in thinking this is the only one left, and one that cannot be bypassed but MUST work? I'm starting to see this system in my dreams, it seems tantalisingly close to working, almost. Chris, email dropped to you with a list of what I've tried thus far. I guess there is more likely to be an issue with the EBV VSV than the EBV itself... I've also driven and then taken the pressure line off the iacv vsv and had a pretty hefty PISH! of released air, so I'm fairly sure the pressure tank and related bits are ok. Edit: This morning I bypassed the frontmost vsv entirely, same issue, and did a test where I bypassed the ebv vsv. Does this possibly mean it's the ebv (of all the parts to go wrong)?
  2. I do indeed, and I'll be able to afford it soon - I'm about to start a new job. Every time I've saved money up it's vanished down a hole in the ground over the last year - 2007 wasn't the best for my car or my finances! I've set the car up to run TTC style and taken the two vv's you are mentioning out of the equation, and the very front vsv that comes off the first turbo actuator I replaced with one you sent me ages ago, if that's the one you meant. Either way, I'm getting under .5 bar of boost, seq or ttc. in seq it's about .5-.6 and then drops to .2. All hoses possible replaced. I'll drop this in a mail as well...
  3. Thanks for the reply Rob, unfiortunately I've tried that - replaced every single hose, and tried testing with ttc as well so the vsv's aren't even a factor. far as I can tell the egcv is only activated by pressure and that seems to work. grrr.
  4. Ha, true enough Chris, but you have to understand I also have the worst luck in the world - redundancies, job losses, major ops where they broke half my face up and moved it around, debt, and a couple of other things keep getting in the way. If I'd had the money I'd have driven it to you at the start and left it! Besides, I've learned a lot about the engine... On that note, I've found using a bike pump of all things that the armature on the IACV AND the EGCV both work fine through air pressure. I'd guess that means they are ok... I'm SERIOUSLY considering just trying to finance a single turbo by now! more room, less to go wrong, easier to fix
  5. It's the large silver valve that sits under the turbos at the driver's side, just beneath the heat shield. Big fat silver looking thing with an arm coming off it behind. Having said that, I've done a pressure test with (of all things) a bike pump and the arm moves fine, so I'm a bit stuck :s Let me check up on it first and then if you've got that part I may need a new one...
  6. I'm sure it's the problem I'm having. It MIGHT be the IACV as well but odds are it's just the one. how much for an unused/second hand one of these?
  7. The armature moves well enough if levered with a screwdriver, so if it's a problem it would be internal to the egcv I suppose - do these go wrong much? I'm sure getting it off won't cause much of an issue relative to recent work. Any clue why the first turbo is running a lower bar than it should? (bpu bits and 1.4 hybrids mean it should be hitting at least 1 bar...) anyone got a working one they can spare?
  8. Right. I'm convinced it's the EGCV. With a fiddle of the balancer box hoses and a bit of tinkering, the first turbo is hitting .6 bar and then it dumps everything and I get about .2 bar. According to the wise Ian C's sequential checklist, and as this doesn't work in TTC, I guess this component is either sticking or faulty. Can anyone give me a hint on a) how to free it up and make it work b) if not where I can get another egcv and c) how much for. Cheers
  9. I've now tried the TTC test with the vacuum hoses - still getting about .5 of a bar. Would that not suggest it's the EGCV not opening? It's the only thing left I can think of. If so... how do I free it up?!
  10. Tried that Ian, same thing! I was trying to get the EVC back in to see if it made a difference - I dont' have the original boost solenoid in the car so didn't know if the car knew what boost it should be running? I reasonaed if it needed a solenoid at least the EVC would provide some help the car's been plumbed as stock for ages and it's made no difference, same boost. Driving me nuts.
  11. Hey all After months of being too arsed off to care (and cycling to work) I have snapped and gone beserk at trying to get the supra 100% again. I've been trying to plumb the EVC back in, but I can't work out, from the manual and from the various tips off here, exactly where everything goes. It;s all a bit too mish mash for me and so I'm appealing to anyone who has an HKS EVC V or similar that they plumbed in hose-wise from scratch to please give me an exact guide! There are 3 nozzles on the solenoid - B, I and O. B is plumbed across to the ETCS, as it always has been, and the gauges come off that so I'm pretty sure that's fine. The I comes off the top of the first turbo (discharge side) and is on a 3 piece connecting the vacuum pipe it would normally sit on and the solenoid, so all three of those are connected - I can't see a problem there either (according to the manual). So.. the O one says it neesds connecting to the wastegate port. The wastegate is still connected to the turbo outlet underneath the first turbo, so I've connected the other port. Seems to make no difference. Basically, with or without EVC, the car is making .5 bar on the first turbo; this drops to .35 -.4 when the second turbo comes in. the evc is the only boost solenoid present. I can FEEL the car wanting to give a lot more power, but it doesn't happen and that makes me sad. If anyone can verify if this is a) the problem 2/problem 4 scenario Ian C mentions in the sequential checklist, and b) can give me a guide on exactly how to put the evc in, I'll be incredibly grateful. Have replaced EVERY air hose (and most water while I was there), repeat EVERY, in the entire system trying to fix this. the engine bay is a riot of blue, my hands are weals of red, and my brain is melting out my ears. Help!
  12. Cheers Ian - do they get removed from below after the bolts are removed?
  13. nads. Now I'M having this. I know what it is too - the driver's side catch presses down but doesn't lock. The other one does, tested with a screwdriver! the driver's side one goes down all the way and then just flips back open. Anyone know how to take one apart and tinker with it? If so I could use a pointer of what to look for! Chars C
  14. Nah, I reckon the after is barracuda style. Before it's a damn SHARK I've got the ridiculous veilside on mine. Hated it at first but it grew on me - especially as I started getting "that black car looks like the batmobile" comments which amused me. Anyone know how to mod a toyota badge to the same size in bat symbol?
