Ultimate Nissan 180SX (SIL80) Track Build!

A rare opportunity to pick up a fully specced time attack project that just needs the finishing touches. The hard work and money have already been spent—take this beast, finish the final 5%, and hit the track with a weapon built to dominate.

After years of building and over $100k invested, it’s time to accept I won’t have the time to finish this incredible project. So here’s your chance to jump in and take it across the finish line.

I originally bought this 180SX with dreams of creating a 300rwkw+ dedicated time attack beast—something fast, reliable, and eye-catching. I only tracked it twice before tearing it down for a full performance-focused rebuild. Since then, I’ve replaced or upgraded nearly every component with top-tier parts, many of them brand new and never used. The goal? Ultimate reliability and huge power potential, with room to go even further.

Every major system—from the driveline to fuel delivery—has been built to support serious power. All it needs to run is some final assembly: install the engine, finish the fuel lines and loom, give it a tune... and go scare some supercars.

I’m in no rush to sell, and I won’t be parting it out—please don’t waste your time or mine with lowball offers.

Quick Highlights:
- Over $100k spent on premium parts and upgrades
- Built for high performance & reliability – just finish and tune
- Genuine top end performance parts throughout
- Sil80 chassis with full cage and track-focused design
- Solid engine and turbo setup, with bulletproof new gearbox, and race-ready fuel & ECU systems
- Perfect base for big-power SR20 build (just upgrade bottom end if chasing even more)

What’s Left To Finish:
- Fit engine and gearbox
- Paint & fit front guards
- Finish fuel lines & wiring
- Tune and 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.

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