ste91 Posted October 2, 2009 Share Posted October 2, 2009 Have you checked all your intercooler pipes are on properly? No leaks? Quote Link to post Share on other sites
micky boy Posted October 2, 2009 Share Posted October 2, 2009 Have you checked all your intercooler pipes are on properly? No leaks?have you checked the vacum pipe that gos from the actuator to the turbosometime they split also what actuator have you got?? Quote Link to post Share on other sites
StarletRick Posted October 2, 2009 Share Posted October 2, 2009 if it isnt leaking anywhere, its going to be the wastegate. silly question... is the spring in it? Quote Link to post Share on other sites
Marck glanza V Posted October 2, 2009 Author Share Posted October 2, 2009 havent actually checked if theres a spring in it (will do that today)its a new pipe im using for the wastegatei have checked my intercooler pipes about 10 times Quote Link to post Share on other sites
Marck glanza V Posted October 2, 2009 Author Share Posted October 2, 2009 definately have a spring Quote Link to post Share on other sites
Sparky Posted October 2, 2009 Share Posted October 2, 2009 Weld the wastegate flap shut on your turbo?? Quote Link to post Share on other sites
Marck glanza V Posted October 2, 2009 Author Share Posted October 2, 2009 yeh got a bracket made upturns out i think my turbo just shat itself because there is a bit of oil in the compressor housing Quote Link to post Share on other sites
Glanza_cl Posted October 2, 2009 Share Posted October 2, 2009 you would still get boost mate, just alot of smoke with it. has to be something to do with a lack of pressure... something to do with the external wastgate possible Quote Link to post Share on other sites
ste91 Posted October 2, 2009 Share Posted October 2, 2009 Is there any movement in the boost gauge needle at all or does it just stay where it is? Quote Link to post Share on other sites
Marck glanza V Posted October 2, 2009 Author Share Posted October 2, 2009 checked the wastegate couldnt find anything wrongthe needle moves from - .65 to 0 then once the car gets higher in the rev range it feels like it might be hitting fuel cut Quote Link to post Share on other sites
Marck glanza V Posted October 2, 2009 Author Share Posted October 2, 2009 also checked for play in the compressor wheel and theres none and it still rotates Quote Link to post Share on other sites
Glanza_cl Posted October 2, 2009 Share Posted October 2, 2009 do any of the three green lights on the dash light up? Quote Link to post Share on other sites

micky boy Posted October 2, 2009 Share Posted October 2, 2009 its must be something to do with the external wasgate like cl said lack of presure Quote Link to post Share on other sites
Marck glanza V Posted October 2, 2009 Author Share Posted October 2, 2009 its must be something to do with the external wasgate like cl said lack of presureany ideas what??????? Quote Link to post Share on other sites
Bildo Posted October 2, 2009 Share Posted October 2, 2009 I know you said you've checked for leaks in the pipes, but I had the same issue. I was certain none of them were leaking but I just took them all off and made sure I did everything 100% perfect second time around, felt where the pipe was in the hose etc. When I put it together it boosted perfectly.Might be worth doing that as it'll be easier than most things that need doing with the wastegate/turbo.

micky boy Posted October 2, 2009 Share Posted October 2, 2009 any ideas what???????im not that clued up on external wastegates are they adjustable? Quote Link to post Share on other sites

Marck glanza V Posted October 2, 2009 Author Share Posted October 2, 2009 i also removed the pipe for the wastegate just to see what happened and there is no difference Quote Link to post Share on other sites
Sparky Posted October 2, 2009 Share Posted October 2, 2009 I know what it is.Take the filter relocation off and drive it I bet yiu have put the stainless pipe too far down the silicone pipe and its restricting the air getting into the turbo, the same happened to me when I fitted mine Quote Link to post Share on other sites
Marck glanza V Posted October 2, 2009 Author Share Posted October 2, 2009 already tried that with no luck Quote Link to post Share on other sites
Sparky Posted October 2, 2009 Share Posted October 2, 2009 Really??? Im stumped then Quote Link to post Share on other sites
Marck glanza V Posted October 2, 2009 Author Share Posted October 2, 2009 so am i. think im gonna have to take it sumwhere Quote Link to post Share on other sites
Glanza_cl Posted October 2, 2009 Share Posted October 2, 2009 silly question but are all the turbo studs done up tight? is there any noise when you drive and try and come onto boost?no whooshing sounds? any noises at all... apart from the rattle you stated? Quote Link to post Share on other sites
