I spend most of my time over at Turboford and I drive an 86 SVO so I'm biased, but you already have the nitrous, just rebuild for a turbo again and clamp your fuel pressure reference line on tight this time! A 75 shot will spool a T3 damn quick!
Tell your parents that a turbo is a safety investment since braking isn't always the answer.
Are you sure that some offset rack bushings and CC plates with subframes and maybe a strut tower brace wouldn't make you real happy?
