Yup, dash pod or steering column pod are probably your choices, particularly if you are wanting to mount all 3 gauges.
One thing to consider(that perhaps you've already thought thru) is that your oil pressure and EGT analog gauges will require additional sensors (since the car has no existing analog sensors for those functions)... and in particular adding EGT will require drilling a hole pre-turbo in the exhaust manifold (post-turbo is next to useless). Tricky without pulling the turbo.
No worries if you're prepared for the work... but if one or more of those gauges is more trouble than they are worth to you it might change the size of the pod you're trying to source and fit.
Folks may weigh in about OBD2-based gauges like the Scangauge and Ultragauge, which plug into the OBD2 port and mount pretty discretely on the steering column or dash, but they won't show you oil pressure or EGT... again, no on-board sensors for them to read.
