With all of the major machine work out of the way, the short block assembled, and all of the parts collected it was time to start assembly of the SR20DET. Mert from RBMS Auto Care in Hayward (Who was a key part in the STI build, and will be helping me with the 510 build) picked up the block and head from Rob’s Auto Machine and began assembly. ARP hardware was used for all critical assembly points to insure the motor was as strong as possible.
With the basic parts of the motor now together, I packed up a bunch of parts and headed over to the shop to start putting it all together. First up was the assembly of the intake and exhaust manifolds along with all the associated parts. For the intake side of things I opted for the Greddy Intake manifold with large bore 80mm opening. Mated to the manifold is a custom built Naprec 80mm throttle body with billet aluminum throttle wheel. To deliver the necessary fuel to the car I opted for Injector Dynamics 800cc top feed injectors mated to a Radium top feed fuel rail. This setup along with the cams and porting of the head should provide plenty of airflow for the turbo.
Next up was the exhaust manifold and turbo setup. Having had fantastic experience with their products before on the STI, I opted for another Garrett GTX series turbo for the 510. I ended up going with the GTX3076 paired with a T3 v-band outlet hotside. Pushing the hot exhaust gases out of the motor and up to the turbo is a forward mount tubular manifold from McKinney Motorsports. The manifold pushes the turbo up and towards the front of the car to help with clearance of both the steering box and the drivers side strut tower. The manifold also features a 38mm external wastegate flange that I mated a Turbosmart 38mm UltraGate EWG to.
With both of the above parts assembled and ready to go I mounted both up to the motor and began with the basic assembly. Adding the Nismo competition motor mounts, oil filter sandwich plate with temp and pressure sensors, water inlet and outlet housings, etc.
Once I had mounted the turbo, which came from the awesome team at Snail Performance, and figured out how it was going to need to be clocked we cut off the elbow that was on from a previous setup and began running the coolant and oil lines from the block. Next up is going to be the final parts of assembly including the oil pan, CAS setup, ATI damper pulley, water pump, etc. and then test fitting in the car.
Stay tuned for the next update coming soon!
One of the first things I had already decided on for the car was the motor. A fairly popular option for the 510, the JDM only SR20DET was the easiest choice for me. With easy to acquire parts readily available in the states, the SR20DET is one of the most iconic motors to come out of Nissan. A turbo 2.0 liter in-line 4 cylinder with accompanying 5 speed transmission it has graced several various cars over its notable history. Of these are the famous and highly sought after Silvias. Starting with the S13 and moving through various iterations the SR20DET provides realiable power in a compact enough package to fit in the 510.
I specifically choose a S13 Blacktop SR20DET out of the 180sx/Silvia. Lots of available parts from both Nissan and aftermarket makes it easy to maintain and build upon. Mine came from Japan through Canada and included everything I needed for around $2600 shipped. After only 4 days in transit the motor arrived at RBMS in Hayward. I headed over there after work to inspect the shipment and begin tearing it down for removal from the pallet.
The motor was in such great shape, with the exception of two valves that needed to be replaced, that the motor could have been run as is without any updating. After going through everything I was very pleased with the purchase and relieved that I had received such a clean motor. Once everything was taken apart, the block and head were dropped off at Rob’s Auto Machine in Hayward for the machining and new parts.
Growing up as a member of the “Gran Turismo Generation” we learned of amazing cars from all over the world that no one here had really ever heard of. As my fascination with all of the amazing Japanese machines of the 90s grew I began to take notice of the older JDM classics. The amazing highway battle cars of the 70s were unlike anything I had seen.
As time went on the love and respect for the old JDM classics grew. My personal favorites being those from coming from Datsun. The 240z, Bluebird/510, and Hakosuka were timeless designs that feel like they never age.
As my bored with the STI grew, my desire to rebuild an old JDM classic grew alongside it. I began researching the cars, looking for inspiration. Low, wide, and chunky immediately drew my attention. Fender Flares and meaty 15″ wheels spoke to me like not many other cars have. I began to formulate my plan and what I wanted to achieve. New-Classic was my theme with the plan being to do a full top to bottom replacement of every component on the car.
Fuel Injected modern turbo motor, modern style suspension, modern brakes, all new wiring, hard lines, etc. were all chosen to bring the 510 into the modern era.
Below are a few samples of what helped drive me towards my ultimate plan for the 510.
