If you get chance to dig out a part number it'd be much appreciated

Does that one include the gaskets for the turbos etc as well Nic? Or is that available in a different kit?

Did you manage to get new gaskets etc? I'll be replacing my turbos very soon so if you could put the part numbers up it would be a great help Thanks.

LMAO!! I gave it the 'kiss of death' there didn't i?? If i get a new set of turbos fitted before this then still count me in

To be fair, i bet that most people running J-spec turbos have chips in them and never even realise. 15 year old turbos & fragile ceramic blades aren't a great combination.

Thanks Dunk! I know what you're saying about not wanting to do the job twice. Trying to find a set of perfect condition J-spec ceramic turbos is a bloody nightmare though Especially as most of the cars are 15years old now. I think i might have to make do with an 'ok-ish' set for now, as long as the seals are ok and they don’t smoke. It's very rare i get to run the car on full boost at the moment as there aren't any big roads near me and also the weathers likely to be crap for the next few months.

Sounds promising! If you can let me know what he says & what sort of condition theyre in that would be great

I didn't know that. Is it a specialist job to swap?

How long were you driving your car with it like this? I'm still wondering if it's safe to drive as it seems fine driving sensibly and keeping it under 4k revs.

Following on from this thread; http://www.mkivsupra.net/vbb/showthread.php?t=232324 I'm in need of a set of J-spec turbos, or at least the 2nd one. Can anyone help? Thanks, Rob.

Just checked and it is the same noise as Scott's was making! Looks like turbo no.2 has gone then! (see what i mean about the lazer pistol noise? ) Anyone know of a set of j-spec turbos going spare?

Some of the kids i teach i wouldn't trust with a pair of scissors! Let alone something that's being connected to my engine lol!!

I've just found your video thread and I actually posted on it too! I can't see youtube vids at work but i'll check when i get home and see if it's the same noise. I'm already over the shock that my turbo(s) are probably knackered. I just want to diagnose the problem now and get it fixed. I don't want to be messing around for weeks trying different things, especially in this weather with no garage!

UPDATE :- Had a fiddle with the actuators yesterday to see if they were moving but couldnt tell. This morning driving to work the car now boosts on the first turbo to 0.6bar but then drops to 0 as soon as the 2nd turbo would kick in. As soon as you lift your foot off the accelerator it makes a noise i can only describe as like shooting a Lazer pistol! I'll try and get a video on the way home. I've seen Ian C's thread about the sequential setup and this sounds like problem number 2 but i'm positive the EGCV is working as i've seen it move during the TTC test. So, i'll still pressure test it later but i guess it could be the 2nd turbo that might have seized?

I've got a baked bean can and a tyre valve so i'll have a go at making something tomorrow at work. Then i'll try and test it when i get home. Thanks for everyones help so far, i won't go dismantling the turbos just yet (although i have read through your guide about 20 times already Tony, in preperation! )

I'll try and pressure test the intercooler & hard pipes just to make sure there are no leaks anywhere. I remember reading somewhere that you can use a baked bean can to block up one end of the intercooler piping and then the same on the other end with a tyre valve attached to it. Anyone tried this or got any better methods? When driving and under load, that's when it just creeps over 0bar on the boost gauge. The cars exhaust is now a lot louder at idle. Exactly the same as when you run your car in TTC mode, i'm not sure if this means anything? Also, does anyone know what the symptoms of a faulty wastegate actuator are? Would this cause the same problems if it was stuck, or broken? thanks.

Congratulations!! That's great news! Good luck to you both!

Thanks for the advice guys The actuator between the turbos seems to be working fine as it was opening & closing when i did the TTC mod earlier. There is a quiet spooling sound and the car is making boost up to 0bar maybe a tiny bit over but that's as high as it goes. I'd say 0.2bar max going off the boost gauge reading. The car has a FMIC fitted with hard pipes and Mikalor clamps. I've had a good look at the joins but doesn't look like any have popped off. I'm wondered whether one of the silicon couplers had split but it seems doubtful. The car also has a HKS SSQV BOV and that looks fine. With the bonnet open and the engine running, i can't hear any hissing and i have to rev the car quite hard to get a tiny woosh out of the BOV. It's not looking promising at the moment!

I'm not ruling it out tbh. I think it's my first turbo that's gone as i'm getting no boost at all. The blades could have gone through the 2nd turbo and also damaged that. I think it'd be madness to just replace with 1 new one. Imagine spending 1K+ on a new turbo only for the other one to break a month or two later and in the process take out the new one!

For a pair; New 2-3K 2nd Hand - £200 - £300 depending on condition and mileage (looking at past 'for sale' threads)

I've held it off for over a year but looks like moving in together is inevitable lol! Should be in by Christmas all being well! I doubt brand new turbos is going to happen. I wish they weren't so bloody expensive It'd make more sense to put the 2-3k towards a single build. Hopefully i can drop on a set of decent-ish second hand turbos which should make it a cheapish fix for now. They seem to be getting harder to find though. If i can't find any i'll have to go for the hybrid route and run them at a sensible boost to make sure they last. There's lots of bad press with Hybrids but like a said, CR Turbos seem to have a good rep, tried and tested with a few members. I'd considered a breaker, or even getting Jurgen to ship me over a complete low mileage engine with turbos but again it's just time and money. I don't want the car to be off the road for months if i can help it. You'll be first in line to help dismantle it if i did!

I was thinking that, and possibly having a go at swapping them myself with the help of a mechanic mate. Anyone know of any good second hand turbos going spare?

I'd love to mate, but i've not got the funds at the moment to do a decent job as i'm in the process of moving into a house with the gf. If i was going single, it'd have to be the real deal, all or nothing! I also plan on having a second car for daily driving before the supra goes single So it seems my options now are; 1. Second hand turbos (hard to find at the moment & risk that they will break) 2. Remove my blown ones and Hybrid them (costly & also a fair chance they will break, although from what i've read CR Turbos seem to have a good rep with members on here) 3. Go single (always been on the cards but as explained before not really feasible at the moment) 4. Brand new turbos from Toyota (Looking at the price & availability doesn't look like this is going to happen) Any opinions on what I should do?

Or at least i'm 95% sure Having just got my car back from its V161 conversion and being over the moon with finally having it running well, it appears that one of the turbos has let go. I was driving on boost when i heard a 'pop' noise and the car instantly lost power. There was no smoke coming from the exhaust. I assumed (hoped) it would be an intercooler hose or a vacuum pipe but i've double checked and can't see any that are split or disconnected. The car now won't boost above 0 bar. I can hear a faint spooling sound but nowhere near as loud as it was before. I've also checked the exhaust for any signs of ceramic blades but found nothing (the car is fully decated) This afternoon i tried the temp TTC mod. I popped the bonnet after a quick drive and both actuators were still held open and they both closed when i pulled a vac hose off (which should rule out the pressure tank and vac hose leak). The car still wouldn't make positive boost though which i guess is almost conformation that one or both of the turbos are wrecked. Unless i'm missing something? Am i right in thinking when an intercooler hose pops off you can still hear the turbos spool but get no boost? The car seems to drive ok despite the complete lack of boost (reminds me of the NA). The question is, will it be safe to drive providing i take it easy? The supra is my daily driver which i need to get to work etc. Is there risk of further damage driving with a blown turbo? Thanks in advance, Rob
