There are several places that you can install those probes. For the EGT you can drill and tap the exhaust manifold for preturbo temps or the elbow out the back of the turbo for post turbo temps. Wont get into the pre/post debate. Drilling and tapping sounds scary but it really is easy to do just take your time. Do a search and you should be able to find detailed instructions for it. As for the boost gauge you can also do one of several choices. One is drill and tap the intake horn, second you can use the port on the head back by the fuel filter housing. Just unscrew it screw in a bushing adapter of the right size or I beileve that Piers has a bolt tapped that just replaces one of the intake horn bolts. Hope this helps some.
