Wouldn't CW be the best bet?

Yeah any help any tuner/supra specialist would be able to offer would be greatly appreciated. If anyone needs to call me (if it's easier) then please PM me and I'll give you my mobile number.

Car boosted for a few seconds on the dual carriage way at full boost, then it was the sort of sound you would expect if you'd popped a hose off properly, then no boost. I expected to open the bonnet to find a popped hose, well, I didn't.

After speaking to Jurgen, I have taken off all the boost pipework, hoses to FMIC, Throttle body etc and refitted them. I have done this twice now to be double sure. I've gone over all the vacuum hoses and I found a pipe that runs from one side of the engine to the other, runs through a bracket on the firewall. This had a hole in it from rubbing a hot hoseclip, I was happy I found this as I was certain it would be the problem. Refitted the pipe minus the hole and car was still the same

Car otherwise runs fine, boost never seems to go above 0.3 bar, when 2nd turbo should come online (4kish) zero boost is showing on the gauge at all

Car idles well, no nasty lights on the dash, no smoke.

First day of Supra ownership hasn't gone well

Starting to wish I'd stuck with my Golf lol

Bless Jurgen though, he's been on the phone to me all day (day before his hols) offering advice and support, top guy. If anyone can help I would greatly appreciate it as I'm at my wits end and feel like crying lol.

SteveR is in your area but he's on hols for a week. As mentioned above it might be worth getting it up to Chris Wilson for a good look over. He'll be able to diagnose and solve any issue the car has.

PS: have you checked for error codes ?

Not checked for error codes no, will have a read up on how to do that...

I've been reading this thread http://www.mkivsupra.net/vbb/showthread.php?t=35926

and the below sounds like my symptoms, but could this have caused the 'blown-off boost pipe' sound that occured as the boost loss problem materialised?

 

Problem 2: I don't get a 2nd turbo rush, and as soon as I should it dumps all boost instead.

The IACV is opening but the second turbo isn't spinning. All the air boosted by #1 turbo now has an easy path back to the non-pressurised side of the turbos via a non-spinning #2 turbo. In effect, it all goes 'backwards' through #2 instead of going into the engine. You'll maybe see .2 or .3 of a bar of boost but that's about it.

 

This usually means the EGCV isn't opening. The turbo can't spin as it has no exhaust gas flow path. Although annoying, this won't do long-term damage as #1 turbo won't generate much boost because the engine loses a lot of power, so no overspeeding or overheating.

 

Well I say it sounds like my problem, the boost is about 0.2/0.3 bar initially then no boost at all.

There are 9 connections on the stock SMIC piping , having such a huge reduction in boost can only happen if one of the pipes pops off. I have had it done to me many times. When the pipes come off, you may look at them and they may seem in place, but you need to pull on them to find out. Thats why HKS do a hard pipe kit, the plastic piping on them are not that good.

I would not be concerned to much , get the car up on the jack tomorrow and have a look at the pipes inside the wing then the ones that go past the rad. the ones which come from the SMIC on the drivers side wing are usually the ones that pop off.

If your turbo's had gone then you would see alot of smoke come from behind, its not your turbo's or anything serious .

if you got any questions give me a buzz tomorrow and ill talk you through a few things over the phone . ill be online most of the day.

Im 5 mins up the rd from Redditch if you want a second pair of eyes to have a look.

Could the intercooler have split ?

Thanks for the advice, appreciated.

It's had a new FMIC fitted by Jurgen, so none of the plastic pipes are still in place, it's now all alloy pipe and silicone hose. I'll take what you said on board though and I'll take the bumper off today and triple check and refit all the hoses and clamps.

I've definately not seen any smoke, I've also got my friend to watch me when I've gone down the road and he said there's nothing coming out at all. I'll triple check everything with fresh eyes today and if I'm still stuck I'll contact you. Thankyou very much.

Thanks dnk appreciated, I'll have another look with fresh eyes today and see how I get on, if I need you I'll give you a shout, thanks

In answer to your question, I don't know, is this actually possible? A problem with the new FMIC crossed my mind yesterday but I don't know if this can actually happen? Can anyone else clarify this?

Hopefully a fresh outlook today will clear things up, was very tired and stressed out yesterday.

you had a FMIC fitted ? if they are standard clamps and that would be your problem. look at the hose fitting inside the wing on the drivers side ..

my mobs 07970 733159 if you need it

i wouldnt rule anything out till i found the leak inc the new intercooler

There aren't the standard jubilee clips type, they are pretty hefty clamps.

I've taken the car out this morning before starting to check things over, took car to about 5k even less boost from Turbo1, zero boost from Turbo 2 followed by lots of blue smoke :(

At this point I thought there's very little point in me doing anything else to the car.

Would sudden turbo failure have produced a sound similar to a hose popping off and sudden loss of boost? Does this sound like turbo failure?

I'm not at all blaming Jurgen for this at all, he's been more than helpful and has made a great effort to try and help me, even contacting me before he got on his plane to go on holiday. It's one of those unfortunate things that happens in the world of cars I think, could have happeend at any time, just don't really know what to do about it now.

EDIT

Car only smoked the once, hasn't done it since?? I was only really speculating Turbo issue and trying to work out in my mind what it could be. It is probably something really simple!

Sorry to hear about this . I have a spare set of turbo's with no shaft play. They are in excellent condition. Have a chat with Jurgen, i am sure he will try and help.

Jurgens just gone holiday, our last communication was to try and get someone to look at it who really knows what they are doing. I'd rather this than keep checking things myself as whilst I'm mechanically minded, I don't know anything about the 2JZGTE engine yet or particularly how a sequential turbo system works...

Basically what I'm saying is that I don't think it's worth me checking anything else, I've checked what I can with my limited knowledge and now I think it's worth handing over to the experts.

Thanks for any advice given so far, just need to find a Supra mechanic near Redditch if possible.

Boost problems aside lets have some full size pics of that stunner.

Hehe cheers Jamie.

Well I'm going to go and do the one thing I can do to it today, and that's clean it

So I'll whack some pictures on this evening/tomorrow morning
