B3any I can fully recommend Chris Wilson to look after, service, modify, repair and advise on anything to do with Supras. In the past Chris has fitted a number of modifications to my car, serviced it, given me great advice on lots of different things and exploded a few myths as well. He also sorted out the repair of my second turbo after it disintegrated about a month ago and shot bits of itself out of the exhaust I am more than happy with all of the work Chris has done on my car and being so easy to get to is a major bonus.

I might try putting the stock BOV back on and see if it makes any difference. Jules

Matt I've noticed similar things and was also wondering what was the cause. On an overtaking move I sometimes have a situation where the 'box changes up whilst on full boost and the power seems to drop for half a second, almost like the engine is catching a breath, then it comes back and keeps going. This doesn't always happen, most of the time the engine delivers a fairly smooth and constant stream of power during the change. Jules

right, thanks Monkey, I'll look into this a bit more..... once CW has put my no.2 turbo back on and the car is up and running again, hopefully early next week

ok, thanks guys. I'll keep doing some research. The car's due in on the 29th of October and I've been told that they can't order anything until the bumper is taken off and they can see what stuff they need. I'm looking into it now to try and stop the delay of waiting for parts to arrive, causing the car to be off the road whilst the front is in bits. Jules

Alex Not sure if this of any help to you but.... I also get a noise when hitting over 1 bar. At first I couldn't track down the cause but it turns out it's the boost gauge. It's a racetech gauge and when boost is up the needle rapidly vibrates around the 1.2 bar mark and makes a buzzing sound. Jules

My car will be going in to have the front bumper and IC replaced soon because of badger damage. I've been told that genuine Toyota parts may take a while to get hold of so I was thinking about getting them to put a different front on. Which front bumper would look best assuming that the IC will probably remain as standard, at least side mounted (no big FMIC to show off through the gap!) and the rest of the body will also stay standard? And am I right in thinking I could get hold of a different bumper quicker? The new intercooler maybe coming from a different source rather than Toyota. Thanks Jules

The car is now at Chris Wilson's and I should know by the weekend just what the problem is. Chris reckons the rattling noise might be parts of the blades that didn't get past the o2 sensor when the thing gave way. I'm still hoping that it's not as bad as it seems but at the end of the day I suppose I have to face up to the reality that I could be facing a monster repair bill When talking to Chris about possible options for replacement he was saying that as it's an auto there are certain things to take into consideration. I was thinking along the lines of hybrids that I've been reading about on the msg board, but as Chris says, I'd have to replace no.1 as well and therefore the cost would only go up. I would like more low down pull from the car and was thinking that maybe the oppurtunity to explore the hybrid route would give this to me but after a chatting to Chris I'm following his advice and, if the damage is a knackered turbo, I'm going for a rebuild of no.2 to retain the same setup. With this and my soon-to-be-repaired Badger damage I'm facing a winter of discontent. Now then, where did I put the details of that money making internet scam .....

Monkey That's good to hear. What difference did youfind with them on, does it give a power increase across the range or just in certain areas? Jules

Hi all Last night on my way home from work I was overtaking someone at a normal kind of speed and the second turbo never came in. At about 3500 - 4000 rpm the engine seemed to go breathless and then boost pressure started to drop and kept dropping all the way to below zero on the gauge. I'm taking it to Chris Wilson tonight for him to give a verdict on what could be the problem - hopefully a hose or something, but I'm fearing the worst. After I limped home I spoke to Chris and he said to check things like hoses, connections, etc., but whilst the car was idling I noticed that when the revs rose for the air con there was a rattling noise from the turbo housing area. When the revs drop again the rattling disappears. Is this rattling a sign of impending doom or is there still hope that it could be something easily corrected? To quote Peter Kay's Mr Softy Top: "I don't f**kin' need this do ah!!"

Justin You're right, it provides endless entertainment. Only problem is I think I've just destroyed turbo no. 2. I've posted a seperate thread to see if anyone can shed any more light on the situation. Syed Are you saying that fitting an EBC would class as an upgrade to the bleed valve? Also, are things like cams suitable for an auto - I thought I'd read somewhere that things like that were only for manuals or am I talking rubbish? As I said above, I now seem to have fallen foul of a blown turbo so now might be the oppurtunity to look into a different turbo setup, maybe something like you mentioned. Thanks Jules

Well, I'm now running at about 1.2 bar and enjoying every second of it. After a long wait for a Super Drager to arrive from HKS, Chris (Chris Wilson, Shropshire) whacked it on to the back of the full decat that he'd already done. A few days later I decided to have a bleed valve and boost gauge fitted as well - next up are water injection and a new intercooler (the current one and the front bumper are suffering from Badger damage, which is being taken care of by the insurance in the next couple of weeks). The new performance has definitely given a glimpse of the car's frisky side and has turned it into a firey whore with an attitude - pure filth Chris has done a great job with the car, I'm more than pleased with all the work he's done so far and he's only about 15 mins away from me, result! To anyone thinking of going down the BPU route then it's something I can fully recommend, it's fantastic fun. Any passengers suddenly stop talking when the power hits, they can't believe this sweet sounding, comfortable car can suddenly turn into a growling, snarling beast. I can also highly recommend Chris to carry out the work, he does a great job and gives an honest and open opinion about a lot of Supra stuff. He also sorted my suspension out and turned the car into something that can handle pretty much anything that I throw at it. I've got a couple of questions for the guys who are already well down this path: What are the next things I should be thinking about doing to the car (apart from the ones I mention above) to further look after it with it's current performance level or to raise the performance, or preferably both, whilst retaining the stock turbos? Are the injectors, fuel pump and other fuel related things on the UK specs still up to the job now, or is this something else to look at? Thanks Jules

Chris I'm going to have a good chat with you about this stuff when I bring the car to you for a service. I'm really fed up with the current setup and don't really feel like trying to make a bad job good so it seems like I'll be investigating the route you describe of a totally new setup. I just want something that can handle the corners properly. I'll speak to you soon. Jules

Lee Yeah, it's a bullet cam, looks a like a tube of lippy but a bit bigger! I was also surprised by the quality. It does produce cracking pictures considering it's size. Also, don't forget that you're seeing an image that has been encoded for the web and therefore contains compression artefacts. I bought the kit off the web a couple of days before I went to the 'ring from a place called rfconcepts. It was about 150 quid as a package which included: camera, permanent mount, velcro mount, battery holder, mic, cables, a little sunhood which screws on the front and a carry case for the whole lot. The website for rfconcepts is http://www.rfconcepts.co.uk/helmet_cameras.htm I bought the Camera 3 package which is the hi-res camera, worth it for that bit extra I think. The cameras are fully waterproof and I certainly had no problems with it whilst on the track or hammering back up the French and Belgian motorways in the rain. I recorded the output on a Sony DV10 which is a DVCAM walkman with a built in LCD screen - perfect for setting up the alignment of the camera. You can record onto a camcorder but it needs to have an AV in socket on it, some do, some don't. It will more or less permanently reside in the front intake from now on (after the insurance company take care of the Badger damage!) and I'll be recording various events etc., from the great view it gives from down there. Jules

Paul So close and yet so far! Never mind, I'm already planning for next year so we might be able to get some of the others interested and get a snake of Supras going round the Nurburgring! Lee I've put up a couple of small clips of some of the shots it got. One is a front view from inside the passenger intake on the front spoiler and the other shows a view looking through the rear spoiler from one side of the car. It's a cracking little camera about 3 inches long and about 3/4 of an inch in diameter. It gave some fantastic pictures when it was mounted in various locations on the car. I held it in the different places with strong velcro which worked perfectly - it stood up to 170 without any problems. The tiny mic that came with it is pretty good too. It gave some good sound from wherever it was situated. Putting it in the engine bay sounded pretty good. For the rear view I put it near the exhaust but I think it got overloaded a bit. The rear view clip shows an NSX approaching behind. This was not far into my second lap and I was making it an exploratory one to try and get some info on the circuit so wasn't really going for it, but when he tried to make a move coming out of a corner I decided to show him a bit of Supra power on the straight! And I had some shit fuel in the tank after filling up at some station in the middle of nowhere before I got to the circuit. I slowed and let him past after that, he obviously had more knowledge of the circuit and with me ripping the arches out I wasn't going to spoil his fun - I wouldn't be happy if somebody did it to me. If you want any more info on the camera let me know. When I get time I'll put up some more clips - I did a lap when it was raining and the circuit was covered in water - tail went out a few times, great fun! Front view Rear view Jules
