I had one!
Janspeed Turbo 3door cossie replica!
Dont know if was same as yours, mine had 7th injector, BIG turbo with HUUUUUGE exhaust housing (Janspeed printed onto exhaust housing elbow), external wastegate, big front mounted intercooler, allsorts.
Would be very interested in hearing any info, esp if mine was a "normal" janspeed turbo conversion.
