we beleive the second turbo is toast...it smells like burning oil when it does open. usually doesnt open jerks and hesitates. Makes a whine noise too.

Well question is since the second turbo is bad would that cause the primary not to spool to 10psi? boost gauge reads 8-5-5 maybe 6.

may have few more mods-those r wht i remember.

 

anyone?

 

Well im not really an expert, but if you hear a whining noise coming from the turbos, then i'd say it's bad. I read a thread a little while ago about another guy who was having the same whining noise from his turbo and turns out they were done.

What I would do, is either have your turbos rebuilt and balanced for about $1,500 to make them like new, or buy a used low mileage set of twins on this forum for a few hundred dollars. While you're there, might as well do a vacuum hose job with silicone hose techniques. Hope I helped

 

figured they were...o well think he wants a single anyways

any idea on how to make it boost higher like it is until we mod it?

 

I had a turbo go out on me. The turbine came off, exploded and went though the motor. Caused me to get new housing. I dont know if this is common but it did happen to me. Just so you know. Also so upgraded engine management?

 

he is plannin on rebuild-port single turbo, fuel, apex,....more...just wnt to know if we can boost higher than we r for now

 

What im saying is if the turbine comes out and goes though the motor it can cause you to buy new housings $720 a piece, new rotors $625 a piece, and other things that dont need to be replaced if the motor isnt destroyed. Like i said i dont know how often this happens but it did happen to me and i needed new housing tacking on $1400 to the rebuild cost.
