Our good friend Anthony S is a hardcore Datsun enthusiast and owner of this sinister 510 wagon. We first met Anthony 20 years ago at the All-Datsun Meet at Mt. Shasta. He started visiting the shop frequently, driving this wagon all the way from Oregon to San Jose, CA and we attended many events together. Anthony built this 510 from the ground up himself, and it has been constantly evolving. He started with a rather unorthodox inline-6 cylinder engine, the Toyota 7M-GTE:
This single-turbo setup spun the ZCG dyno to almost 400rwhp. Anthony is a track nut and the 510 has seen many days running hard at Portland Int. Raceway. Suspension and brake modifications included Brembo calipers up front, a linked Ford rear end and massive 255/35 tires in front with 285/35 rears.
The car went through some serious development including a full 2JZ-GTE engine, rear-mounted radiator setup and larger fender flares–all fabricated by Anthony himself!
In his quest for more power Anthony visited Z Car Garage in 2016 for BC cams and Haltech tuning. We started with a baseline of 399hp/332tq to the wheels. After the cams/tuning it made 461hp/362tq at the wheels:

Let’s hear about Anthony’s latest modifications leading up to the dyno tuning session in 2022…
Anthony: During COVID I had a lot of extra time and money and had stupidly run my prior 2JZ out of oil after hitting the oil pan on a pavement cut. It appeared to be down on power despite not smoking or knocking, I decided to bite the bullet and go with a new engine. Toyota still sold the 2JZ GTE short block brand new, and they also sold new bare heads. Obtained both over a period of several months. I snatched up the last short block in the Portland area and got a new head through OCD Works who did the head work including a custom CNC port job, GSC S1 cams, shimless buckets, and Supertech valves.
In addition to the engine upgrades, the 510 received larger wheels and tires BBS RS sized 18×10 F 18×11 R with 295/30F 315/30R Toyo tires. The brakes were also changed to Stoptech ST-60 calipers with 14″ custom Coleman rotors and C5 hats:
Anthony: I went with a Borg Warner EFR 8474 for the turbo and a quick spool valve from Diesel Pump UK (more on that later). The quick spool valve can help with boost onset by as much as 500 RPM so I was pretty excited to see what would happen on the Dyno with this bigger turbo. The goal being to run pump gas and get 500 plus at the wheels without horrible lag. I tuned the car well enough on the Haltec 2500 ECU to get some testing in before I went to California and to make it drivable. A key to the drivability was the ability of the Haltech to control a drive by wire Bosch throttle body. The road trip down with my wife went well and we arrived in San Jose excited to get the car on the dyno and see what Rob could do. I really tried to do everything right on this build with no shortcuts so I was pretty confident things would go well… Famous last words.
Dyno Tuning at Z Car Garage
Before getting on the dyno, Anthony and Rob went for a test drive and they were not impressed with the power. The car was previously tuned at 460rwhp back in 2015 on the old engine so he was familiar with the car and the speeds it would go. In that trim the car hit 147 MPH in the half mile which is pretty much on par with a Porsche GT3RS from that time (2016). Once back at the shop the car was put on the dyno and the results confirmed their concerns…
Anthony: The car was definitely down on power. Rob asked if I had synced the timing with the Haltech. I was confident it was correct, but I had not actually done that. So we pulled the plugs to confirm that the crank pulley was lining up with the number one piston at top dead center and it was. So issue number one was ruled out. We also thought it might be something to do with the drive by wire throttle not opening all the way, but that wasn’t the case either. Several runs were made and it was hitting a little over 400 at the wheels but the boost was 18 PSI or so. I knew that was way down on power because with the old engine it was hitting 400 plus at 11 or 12 PSI. And I had a better turbo, a better head better cams, etc, so at this point things were pretty disappointing. It was also quite hot that day for San Jose reaching the upper 80’s. To add to the fun the plastic drive by wire pedal that I had modified with a plastic welder ended up breaking on Rob leaving him with no way to move the throttle other than by hand (he was not having that…)
Luckily superstar Josh was able to pull the pedal repair it. Coolant was found under the car and traced to the heater core failing. Anthony disconnected the heater hoses and looped them, but still no solution for being down on power.
Anthony: Somebody had the idea of looking to see if the quick spool valve was operating properly. It turned out it was not. It is supposed to open and allow exhaust gas into both sides of the turbo after a certain PSI and it was not opening. So all of the exhaust was going through one portion of the turbine instead of both. A brief discussion was had about how much this would matter, we all determined it probably mattered a bunch since we were only utilizing half the turbo. Despite all my efforts to hook everything up properly I had made an error in supplying boost to the quick spool valve.
Once this was corrected the horsepower significantly increased. We decided to replace the new boost controller with a Greddy Profec with Josh and Anthony wiring it in so Rob could focus on tuning. After a few runs it was determined that the quick spool valve was putting a weird bump in the torque curve and instead of tuning it more with that device we ended up safety wiring it wide open.
Anthony: So what had started as a day that I thought would go very smoothly had many, many hiccups. But once all were solved, the horsepower really started to skyrocket. There are a lot of numbers thrown around about these engines, but if you do your research anything over 500 at the wheels on pump gas is quite good. I’ve always wanted to run this engine on pump as I don’t have E85 near me and we use it on a lot of road trips and I’ve never wanted to be restricted on fuel. Yes I could use flex fuel… but given the lack of E85 it’s never seemed worth it. My dad had always joked that it would be cool to have 510 horsepower in a 510 and we did hit exactly 510 at one point, then 536, then up to 546 at the wheels on 91 pump. Rob had Josh also adjusted the cam timing a bit as I have Titan adjustable cam gears. Needless to say I was pretty ecstatic getting nearly 550 horsepower and over 440 ft lbs at the wheels on 91 pump gas. The boost was 21 PSI for those runs with a red line near 8000. Now the car really was as fast as I thought it should be…

Enjoying The Ride
Anthony was stoked on the dyno tuning results:
Driving back to Rob’s that night on the freeway he had me down shift into third and nail it and it broke the tires loose on the freeway. Keep in mind these are 315/30/18 Toyo R888r’s. That’s plenty of power for me… Thanks to Rob, Josh, Nick and everybody else at Z Car Garage for their patience and help that day and for working through the issues on this home built POS! You’re the best!
The 2JZ-powered Wagon returned back to Oregon where it continues to live the daily-driver life. The list of activities includes many track days at PIR, work commutes, camping trips and even lumber runs for home projects:
We loved to see Anthony and his wife Jessica at the epic 2018 Rolex Monterey Motorsports Reunion where Nissan was the featured marque. In true #doitinadatsun from, the couple made a roadtrip from Oregon in the 510:
Speaking of road trips, Anthony recently visited us again for the 2024 Rolex Monterey Motorsports Reunion and made the 2000-mile journey from Portland. Check out his pre-flight checklist:
He made it home without incident, because Datsuns are Driven! Follow Anthony’s 510 adventures on his Instagram.
