Big Supes Posted September 1, 2014 Share Posted September 1, 2014 My car is no longer hitting over 1 bar of boost and both turbos seem to be operating as they should with no smoke or sounds of stalling so, after a suggestion from a fellow member, I have been looking into changing the turbo link pipes (as they can perish and collapse internally). The problem is, I can't seem to locate them on my car... and I have a feeling someone is going to tell me that the UK spec turbos don't have them. Can anyone confirm this?

mattdavies Posted September 1, 2014 Share Posted September 1, 2014 Do you want sizes for them ? I looked the other day at replacing them and found Samco hose that needs cutting to size for £50 ish Quote Link to comment Share on other sites More sharing options...

Big Supes Posted September 1, 2014 Author Share Posted September 1, 2014 So, I have two pipes to replace... just to be sure, I take it it's the two that run in line together and not the one in the middle that is off to the right and under the vac pipes?

mattdavies Posted September 1, 2014 Share Posted September 1, 2014 There is another one underneath. Have whatsapp'd you the lengh and diameters Quote Link to comment Share on other sites More sharing options...
Ric Posted September 1, 2014 Share Posted September 1, 2014 It's the black accordian style pipes. Whifbitz sell them in black or blue for about 45quid. Although your boost problem is more than likely down to a faulty VSV or cracked vacuum pipe than a collapsed boost hose. Quote Link to comment Share on other sites More sharing options...

There is another accordion style pipe (see pic) that is between them, off to the right hand size, under the vac pipes as well. Ignore that one? Would running TTC eliminate the VSV do you know?

Ric Posted September 1, 2014 Share Posted September 1, 2014 It's not accordion its a normal straight hose, but changing it wouldnt hurt. TTC usually shows up VSV issues yeah but ive never used this so cant be much help. Quote Link to comment Share on other sites More sharing options...

TTC usually shows up VSV issues yeah but ive never used this so cant be much help. Cool, thanks for confirming. I've been running TTC for a couple of days since reading it can eliminate a faulty VSV and it hasn't made a difference. Once these pipes have been changed I'll start looking elsewhere. All vac pipes seem to be ok. Quote Link to comment Share on other sites More sharing options...

Jellybean Posted September 3, 2014 Share Posted September 3, 2014 (edited) Just finished Complete intake pipe out Front turbo hard plpe and loom bracket tray so you can get at the bolts for the pipe 4 jublie clips on the link pipes Section of the. Greedy intercooler piping removed over by the intake Tools needed are a 10mm and 12mm , socket extentions , 1/2 and 1/4 drive rachcets, Philips and flat head screwdrivers Link pipe removal is messy, pulling and pushing , same to get the new ones back in ; tight squeeze Might make life easier to remove the rear turbo pipe too but the by is up against the firewall so up to you I would estimate 1-1.5 hrs for a novice mechanic like me My pipes are not too bad on a 21 year old car, not bad enough to cause enough restriction to imped performance Loom Bracket Tray Edited September 3, 2014 by Jellybean (see edit history) Quote Link to comment Share on other sites More sharing options...
Big Supes Posted September 3, 2014 Author Share Posted September 3, 2014 Nicely done Jellybean and thanks for the heads up. Yeah, wouldn't have thought your pipes would have caused any restrictions in boost... Quote Link to comment Share on other sites More sharing options...
girth45 Posted September 8, 2014 Share Posted September 8, 2014 I also have same problem, 1997 vvti TT auto tiptronic, was hitting 1.2 bar in mode 2 on my ebc , now only hitting 1.0 bar intermittent. Have new link pipes from whifbitz to fit tomorrow, have also checked condition of impellers on both turbos( no problems there) checked all hoses for cracks ( none found) will replace all as_ matter of course, was_wondering if it may be boost controller solonoid? If any one can help would appreciate. Gary. Quote Link to comment Share on other sites More sharing options...
Big Supes Posted October 25, 2014 Author Share Posted October 25, 2014 Diagnosis as promised to those who were kindly helping me at JAE: blown welds on the standard IC. God knows how long this has been effecting the car. Time for a Chris Wilson or Whifbitz SMIC! Quote Link to comment Share on other sites More sharing options...
Westy Posted March 11, 2015 Share Posted March 11, 2015 Pricing these link pipes up at the moment. £41 inc vat each from Toyota now!!! Whifbitz £48 pair JS performance £59.50 for 4 (two Supras) I've seen many people getting them cheaper but am I not right in saying that they have to be fluoro lined silicone to prevent them from degrading?

Jellybean Posted March 11, 2015 Share Posted March 11, 2015 I would get the OEM units, quality is superior to the Silicon alternatives The OEM pipes did not look too bad after 21 years on my car Quote Link to comment Share on other sites More sharing options...
Samurai 20V Posted March 11, 2015 Share Posted March 11, 2015 If the car is not boosting properly in TTC, then there is a leak one of the vac hoses, or the pressure tank is faulty.. This does not go to say that VSV's are not also at fault, but gives you a starting point to troubleshoot. Quote Link to comment Share on other sites More sharing options...
