Tell us the story behind your ride. What made you pick this particular one? Where did you find it?  This Z was my 7th car. Growing up my family owned a small used car lot, so i managed to own a few different cars, including a 5-spd 1989 Honda Prelude 2.0 Si, a 1968 Pontiac Bonneville, and 1990 Infiniti M30. But not a single one of these made me feel as happy to drive as the Z.   We initially picked it up as an auction car with 128,xxx miles back in 2012. Little did i know, it has become the longest owned car i have ever had.  Describe the modifications you've made. Where did you start,   what’s the most recent mod and what motivated it?  At first, the only changes to the car included stock parts, like a new radiator, a new fan, etc. But about 2 years after I bought the car, a friend introduced me to autocrossing, and this is where the mods started. My step dad has a   shop   that specializes in restorations, so this is where the car lived for about a year while i amassed parts, and prepped for the engine/transmission/drivetrain tear down.   Early on i knew i wanted to keep it N/A as doing turbo would have been too costly and complicated, and besides i already enjoyed the way the car felt. I focused on getting the car to be more reliable and cooler, while making what was already there more efficient.  I've already had a couple full open track days at   The Firm  , and the car was well behaved, stable, and maintained temps for a full day of track driving.  Of all the mods you’ve made, which do you think offers the biggest bang for the buck?  My favorite mods were the short throw shifter, lsd rear end, and the exhaust. The short throw made a huge difference! It reduced the throw from what seemed to be a couple of inches, to a wrist flick. It also made the gating feel more crisp. The LSD is just great in the rain, and really makes its presence known while cornering. The exhaust note is an ear splitting/pleasing low bassy growl mixed with a trumpet lol  How did you go about selecting the specific parts for this build? Any installation tips to share?  The worst part about owning one of these is the lack of parts availability.   The Z Store   is great for upgrades, but upgrade choices are limited, so there's no real room to spread out.   Fortunately, there are some parts/upgrades that swap over from the Z32, that enhance the Z31. They just take some research and massaging to fit.  What are you planning next?  At this point, i just need some new tires, and another day at the track!  But an electric fan would be great.  What’s been the biggest challenge with this build?  The amounts of research, and finding the right shop for the right job. Thankfully there was a machine shop in my town that could help with my cams, heads and block. We have a   Z car specialist   who helped with rebuilding the transmission, and fine tuning the motor.  Final Thoughts?  It's not fast, it's not refined, it's not outstanding, but it's quick, it's raw, it clanks, clatters, and shakes, i built it, it's mine and i love it.
