I've recently fitted a new clutch and spigot bearing so the engine had to come out.. Anyhoo on removing the engine the T-piece between the actuator, outlet on the turbo and the boost solenoid broke up into pieces as all the pipes had gone brittle with heat.

I've replaced the pipe work and t-piece but now the car does not seem to be boosting, it used to pull like a train and now it feels really slow, I can hear the turbo spooling but no where near has loud as it used to sound.. I've got a 3" HKS down pipe and it used to sound awesome

Does the bore of the pipes to the solenoid/actuator have any effect on boost levels? The ECU hasnt raised any error codes so I assume everything is wired up right..

Thanks for any help!

 

Did you put the pipe with the restrictor in it back in the right place?

It should be in the pipe from the compressor nipple to the t-piece.

Andrew...

 

Restrictor??? Oh dear :| I didnt know there was one there..

 

Like Andrew said - small brass restrictor in the hose going between the T piece and turbo outlet. Needed as a small but vital part of the boost control system.
If it's gone, fear not - they can be got from your friendly local 'stealer' for not much cash!

Cheers guys!

I've still got the pipe, but the pipe is falling to pieces, is it easy to insert it into a new piece of pipe without damaging it?

 

Very easy.
Just push it out (may have to gently cut and prise the old rubber pipe apart if heat has bonded the restrictor to the pipe) then re-insert into the new hose. I used a little wooden BBQ skewer when I changed mine on my old bugeye - strong enough to push but won't damage the restrictor.

Cheers,

Stewart.

 

Thanks will give it a crack tonight then take it for a test drive! My heart sunk on sunday evening when I took it out after fitting the new clutch and it felt like it couldnt pull the skin off a rice pudding

 

What turbo do you have? I have plenty of TD04 restrictors in good pipework.

 

TD04 at present got a VF24 ready to fit but im in two minds about it lol!

Will have a crack at removing the restrictor but if I have no luck I'll take up your offer if possible thanks!

 

Bugger there is no restrictor in the pipe that goes from the turbo nipple The tpiece im using now does have a much bigger bore though.. I might have to take up your offer Andrew

 

I just took the car for a spin with the actuator pipe disconnected and it boost like a **** as expected.. So theres definitely a problem with the either the solenoid or the restrictor is the problem, but as there wasnt one in the pipe it cant have had one in the first place?
