You might have picked up this issue because you either drive an S-chassis car or are trying to get into one. But if you’re new to the game, let’s get a few things out of the way…
While more than ten years old, cars like the Nissan S13 and S14 are hard to knock (unfortunately, the S15 was never offered in the US). It’s a potent rear-wheel drive performance coupe that won’t break the bank. And with a few extra bucks, you can make ‘em faster than your mama’s Lexus.
Badged as the 240SX, they were basically the American brothers of the Japanese Silvia with the exception of the engines. The JDM model got a 2.0-liter turbocharged engine called the SR20DET while us Yanks got a 2.4-liter naturally-aspirated four-cylinder known as the KA24DE. We could spend hours arguing which motor is stronger and has more potential, but in the end many experts agree the SR is a better package. Compared to the KA, it require less money and labor hours to get reliable and solid power—just a few bolt-ons can net you 300+whp. Because of this, SR motors have been hot item for years. To this day finding an affordable engine isn’t hard. So to help you, we compiled a list of the most relevant SR20 bolt-ons available that’ll help you get you the power you want.
BC Cams Giveaway
We confiscated a set of Brian Crower cams from our shoot with Eva but since none of the staff drives an S13/S14, we’re giving it to one of you. So, if you think your SR-swapped Nissan deserves them, send an email to us at firstname.lastname@example.org and tell us why.
This stainless steel pipe deletes the cat and improves exhaust flow on factory or aftermarket turbo SR20s.
The more power you go for, the more heat it’ll produce. Mishimoto intercoolers can help keep the air cooler. They’re offered in different sizes.
Stage 2 Cams
These cams are a simple plug and play application that’ll give improvements across the board. These pictured are 264°/264° with 12.06mm/12.06mm lift, shorter duration for good street driving but BC also has race cams available.\
TD06 20G Turbo
Rated to 400-450hp, this affordable turbo bolts on to any bottom-mount SR20 manifold.
Intake Manifold Plenum
This cast-aluminum intake manifold allows large volumes of air to get evenly distributed to each cylinder. Best results come with a big turbo, of course.
EXTREME Turbo Exhaust Manifold
The Tomei manifold is made of high quality stainless steel and TIG-welded to perfection. Comes with everything you need including the gaskets, heat tape and manifold accessories. It’ll immediately improve horsepower and torque on stock and aftermarket turbos.
