If you’ve been following me on Instagram (@buildthreads) you might have seen a story I posted on the weekend showing some upcoming mods planned for the car. One of those being a fresh set of rubber! The tyres I had on the car were getting close to a decade in age, and even after a couple of track days, skid pans, and plenty of mountain runs, they just wouldn’t quit. While the tread was still plentiful, the compound had become hard and useless (yay free horsepower!), and a great deal on some Hankook R-s3s saw me getting the credit card out.
When I posted a small update about my own Datsun the other day, it reminded me of a build that I’ve been meaning to post for a while. This car may share a model name and basic shape with my own, but that’s where the similarities end. This 510 has been cut, chopped, grinded and welded to within an inch of it’s life, now sitting on airbagged Toyota truck suspension with an angry rotary engine on tyre smoking duties. It may look rusty on the outside, but underneath that wonderful patina are some surgical-grade underpinnings.
It’s been a hell of a long time since any real work was done to Project 510. In fact, looking back at the archives, it’s been around 2 and a half years since I ripped it apart and fitted my FMIC and supporting mods! In that time I have driven the car plenty of times (including a track day and skid pan), which is what it’s built for, so I can’t complain about that. Let’s not forget I also built a garage recently, so that counts for something, too! (I should probably also mention at this point that my wife gave birth to our first child at the end of March)
Let’s wrap this up, shall we? This fourth (and final!) segment will be all of the satisfying stuff. Now that all of the fabrication and test-fitting had been completed, I could move on to the fun stuff; making everything pretty and bolting it all back onto the car.
Part 3, here we go. To quickly re-cap, Part 1 was all about relocating the alternator with custom mounts, and Part 2 saw the intercooler and radiator bolted into place, and the intercooler piping tacked together. Now we’re getting down to the finer details.
When we left off from the last update, I had successfully relocated the alternator and had the crank pulley machined down to one single groove, with a smaller belt fitted to suit. I was now ready to get back to the original task at hand; fitting the intercooler, radiator, and modifying the intake manifold.
Well, where do I start? This is going to be easily the biggest update I’ve ever posted about the car, as I’ve just completed 8 months of on/off work under the bonnet in my spare time. During those 8 months I also sadly lost two of my beloved grandparents, went a holiday to Europe, and have attended 4 weddings, so things may have taken a little bit longer than usual.
