Dim Sum Posted May 28, 2012 Share Posted May 28, 2012 Just wanted to ask if anyone could give me a hand. Some of you guys might know that i had my turbos rebuild and fitted by Paul but once i got it back its still not boosting properly. Its boosting at 0.5 check all pipes and etc. I didn't look at what pauls done because i assume it should be perfect. Im at my ends wit with this problem. The supra just don't feel right, seems like the second turbo don't kick in. Im not a mechanic or anything and have spend over £2000.00 just to get the turbo re condition and fitted back on So i guess what im after is some help locally. Because i can't afford to take it back to Paul and get it checked. Quote Link to comment Share on other sites More sharing options...
tooquicktostop Posted May 28, 2012 Share Posted May 28, 2012 Have you spoken to Paul, does not sound like you have ? Quote Link to comment Share on other sites More sharing options...
Abz Posted May 28, 2012 Share Posted May 28, 2012 As Dean mentioned I'd speak to Paul first, if his carried out the work then chances are he will know what could possibly be wrong. Quote Link to comment Share on other sites More sharing options...
Dim Sum Posted May 28, 2012 Author Share Posted May 28, 2012 I've spoken to Paul. At first he said that it might be my boost controller which is faulty and causing this so i accepted that answer on Friday. On Saturday i decided to remove the boost controller and fit the hoses back to the stock system then took it out for a drive and to my surprise it was still boosting at .5. Later i got my intercooler check for leaks and its fine too, i didn't want to play around with the turbo system since Paul has recently check and fitted it back. On Monday i explained what happened over the weekend about the controller and etc. Only solution was to bring it back to him to check on a hourly rate which i can't afford right now.

Swampy442 Posted May 28, 2012 Share Posted May 28, 2012 Where the 2 turbo inlets meet theres a pair of rubber corrugated bellows. They collapse sometimes restricting the amount of air getting to the turbos, worth a look... Quote Link to comment Share on other sites More sharing options...
tooquicktostop Posted May 28, 2012 Share Posted May 28, 2012 Have you tried running it in TTC to see if you have stock boost then Quote Link to comment Share on other sites More sharing options...
ronttuk Posted May 28, 2012 Share Posted May 28, 2012 TKs it to supraloopy he's knows supras inside out he's in Southend Quote Link to comment Share on other sites More sharing options...
j_jza80 Posted May 28, 2012 Share Posted May 28, 2012 Have you checked the solenoids on the sequential system? As Dean mentioned, it's worth trying it in TTC to see of it then boosts correctly. If not theat, check all of the vac ref pipes. Quote Link to comment Share on other sites More sharing options...

I ain't tried the ttc mode because im not one hundred percent sure what goes. The only thing is changed was that a brought a set if polished turbo pipes off Paul. Don't think the pipes j spec and UK spec make any differences. Quote Link to comment Share on other sites More sharing options...
Chris Bailey Posted May 28, 2012 Share Posted May 28, 2012 The #2 turbo on my dads supra isnt working at the moment We have done the ttc mode so it bypasses the valves but still no second turbo. The only others is the turbo itself or the pressure pipe thing lol. Quote Link to comment Share on other sites More sharing options...
markssupra Posted May 28, 2012 Share Posted May 28, 2012 Had same problem on mine last year, if your going to bluewater meet friday ill have a look at it. No promises though. Have you checked the vac pipes from the pressure tank, you really need to check those from underneath the car, you cant see very well from above as inlet manifold obscures it.

letmeshowyou Posted May 28, 2012 Share Posted May 28, 2012 I think it's the vac pipes to the pressure tank, or the tank itself Chris. Impossible to see from where we tried. Didn't think to get underneath it! Quote Link to comment Share on other sites More sharing options...

Pig Posted May 28, 2012 Share Posted May 28, 2012 Would love to help if I can (near stansted airport) but I can remember very little about the twin setup. If you are local, feel free to drop by! Quote Link to comment Share on other sites More sharing options...
Dim Sum Posted May 29, 2012 Author Share Posted May 29, 2012 Would love to help if I can (near stansted airport) but I can remember very little about the twin setup. If you are local, feel free to drop by! Sorry just got back from A&E. I'm based around Southend-on-Sea. Think i might try the VSV that chris said on page 1. But just to make sure i probably get someone to drive it and make sure what i described is right. Quote Link to comment Share on other sites More sharing options...
Pig Posted May 29, 2012 Share Posted May 29, 2012 Supraloopy is your man, he is Southend way. You would be crazy not to pay him for a diagnosis. Good luck Quote Link to comment Share on other sites More sharing options...
letmeshowyou Posted May 29, 2012 Share Posted May 29, 2012 Completely agree with pig but I'm happy to give you a hand trying ttc at some point if it helps Mark not sure yet matey, need to work out times in case I can get out for the food thing. I'll pop you a text later in the week. Quote Link to comment Share on other sites More sharing options...
tooquicktostop Posted May 29, 2012 Share Posted May 29, 2012 I would give Dave a ring before you turn up at the workshop, he had a ton of work lined up when I visited yesterday, he will be more than capable of giving you a diagnosis however Quote Link to comment Share on other sites More sharing options...
