Rebuilding Nissan SR20 for Reliable Power

Fitting a Silvia S13 for Drifting and Time Attack

The renowned Nissan SR20 powerplant is a favorite among customizers to be placed into classic-style Japanese Domestic Market (JDM) vehicles, such as the 240Z. Moreover, it has been utilized in scores of other swap tasks which does not involve the Z family. If pipe dreams of enhancing and adjusting are enacted, this motor could theoretically reach upto 400 horsepower with dependability. Luckily, professionals from MotoIQ have presented an easy guide for securing poweful performance from the jovial SR20 unit, all without fiddling with the lower end.

The aim is to create a dependable engine for an S13 in order to avoid problems like inferior oiling and overheating. The presenter estimated that the parts needed for his list would equal approximately 330 hp, accentuating quick response and good torque at low speeds, which makes it perfectly suited for drifting and time attack competitions.

Easy Bolt-On, Big Power Nissan SR20!

From the start, Mike recommended the initial alteration be a great turbocharger. For this particular build, he opted for the Garrett GTX2863r with an optional .86 housing. This selection is equivalent to stock size, however, it implements advanced technologies thus propelling faster spooling and delivering more power. In conjunction with the modified turbo are constituents from ISR Performance. This includes the intake manifold, O2 sensor housing, and downpipe.

Migrating to the fuel setup, DeatschWerks 1,200cc injectors in combination with a Fuelab fuel pump are strongly suggested for reliable effectiveness at a cost-effective expenditure. These devices are fitted onto the GReddy intake manifold which Mike says should generate an addition of 30 to 40 horsepower over its stock unit. As lower boost levels will be utilized for dependability purposes, a 15-20 horsepower increase is anticipated.

Mike put forward the Jim Wolf Technology C1 camshaft as a suggestion, that does not give in to vibrations quickly. Ergo, it is best suited for motor vehicles dispatching the rev limiter in powerslides. Despite this endorsement, Mike still advises pairing this cam with JVT valve springs as they are coordinated with the cams. Moreover, JWT cam gears were chosen for this particular setup.

Equipping his vehicle with many additional components, Mike has chosen a GReddy tube and fin front-mount intercooler which he sees as particularly well-suited for both street racing and drifting. His associate also proposed that for drag and street use, a bar and plate system could potentially serve better. Along with the intercooler, Mike has included GReddy air intakes and a blow-off valve in his project.

The build of this car is all about reliability, so the tune is kept at 330 hp. Nonetheless, according to Mike, the engine is “super strong” and can handle much more power, as evidenced by the 500-hp Datsun 1200 Coupe driven by a young professional drifter from London.

The craving for dominance will forever be present, yet for those starting off in the Japanese Domestic Market environment, this is an optimum avenue to obtain extra potency without digging deep into one’s pockets.
