Ultimate Nissan 180SX (SIL80) Track Build!

After a couple years trying to finish this build, and over $100k spent on it, I've come to terms with the fact that I don't have the time to put it back together.

After buying the car, I tracked it twice, with a brake line failure the first time, and blown gearbox the second. That triggered/inspired me to strip it back and completely rebuild, so I bought a new engine, gearbox and just about everything else I could find to make a reliable and bulletproof track car. I was aiming for a 300rwkwish dedicated time attack track car, but kept in mind I would likely want much more at some point. This has everything you need for a reliable and competitive track beast, that looks awesome to boot! Everything from the fuel system, to driveline has been built for huge power and reliability. If you want to push it for more power, then all it needs is the bottom end, everything else can support a lot more power! Most of the parts are brand new and never used.

Over $100k (and a lot of time!) has been put into this build to date, so save yourself the time and money and grab this track car package. May be slightly negotiable, but don't bother lowballing. I'm in no rush to sell it. I won't reply to messages for individual parts or lowballs.

The main work needed is to paint the front guards, put the engine back in, finish the fuel lines and wiring looms and give it a tune. Then enjoy!!

Got plenty of photos, so just ask if you want to see something. The photos of the car at the track (including the Bride seats) were before the complete strip down and rebuild, so a a few things have changed. As I think of more things, I'll add them to the list. Obviously no test drives as it still needs to be put back together.

Note, the photos of the car with the white guards are taken in Jan 2025 to show how the car is now.

Looking to replace it with a track focused 2022+ BRZ/GR86 (road registered), so open to swaps with cash adjustments for the right car.

Pickup in Epping, Victoria. Can send interstate at buyers expense.
