i was wondering on a turboed car and u were needing to put gauges like the boost, oil pressure, and egt gauges, is there drilling needed to install these somewhere on the manifold or anything of that sort in the engine bay? thanks a lot guys....

 

Out of those guages, you'll only need to drill a hole in the exhaust manifold for the egt.

 

thanks...and are those other two gauges just like a plug in sensor....

 

For the boost gauge...........Just find a vacuum line and use that. You would just need a t bar type deal to "splice" into that vacuum line. Unless it is unused. ON my 240, I removed the carbon canister, so that was 2 vacuum lines right there.
