Start by working through this troubleshooting guide:

There's a vacuum box that has two vacuum hoses on it. It's near the top of the engine. Kind of under the strut bar. Near the oil fill. I know if one of those come off, only one turbo will work.

 

New engine - just rebuilt - stock turbos - Car isn't hitting any kind of boost until the secondary turbo kicks in. I'm getting alot of heat in the engine bay (turbo related). engine is operating at normal temps. I've checked through most of the vacuum hose ( all new) everything looks good.

Also getting a fluctuation in the idle which goes away when I tun on a power accessory like headlights. I've heard idle fluctuations are usually the cause of a vacuum leak somewhere. However it's odd that a change in draw from the battery would make this go away.

 

Do you have a boost gauge because its kinda hard to troubleshooting boost issues without one.

 

yes I do have a boost gauge

 

any ideas where I might find a bit more detailed information about how the tubro system works?

 

Sorry Trek, I merged the wrong thread.

Anyway, take a look at the link I posted above in this thread. It's a troubleshooting guide for the stock twins.

 

no problem man, I did find the link and got more than enough info to keep me occupied for the day.

thanks again
