im putting a ls/vtec engine in to my 93 delsol s what gauges im i going to have to use and will it need the same one if i don't do the vtec head?

 

what do you mean by gauges? Are you speaking of swaping out Gauge clusters? or do you mean additional gauges like from Autometer/Faze/EDO etc???
Just cause of the swap you don't have to put in a diff gauge cluster.
Hope this may help or get additonal info.
