If this is the old unit which has the large SU up front, then I ran one in a 240Z for a couple of years.
I found the on boost performance great, but off boost the car was sluggish and generally the fuel economy was terrible. I found that the SU has to run very rich off boost in order to cope with the demands of the Turbo on boost. Driving the car fast took a little planning and foresite to allow for the turbo lag. Eventually sold the turbo when it blew the third head gasket.
Generally it was great fun, but the whole set up was too fragile for my liking.
