well the way my piping is running i cant see the window on my tranny to check the igntion timing. is it ok to let the car idle without the pipes hooked up to the turbo. i know u cant drive it like that cause it will over rev the turbo... my idle is about 1200.

 

You'll be fine, as you know, just don't drive it like that.

 

yeah, you'll be fine - the turbo is likely to not even be turning at idle, and even if it is, there's NO WAY that you'll have to worry about over reving it
