Every Honda Ok-Series Engine Ranked From Worst To Best

Sometimes the OG stays on high of the pile. The inaugural K20 motor won’t have essentially the most inventory horsepower or the biggest displacement, however in terms of availability, versatility, recognition, and accessibility, the unique stays the favourite of Honda followers world wide. From 2000 to 2011, the K20A got here in a number of variations, producing energy ranging between 155 and 220 horsepower and between 132 to 152 lb-feet of torque, relying on the 12 months and variant.

Honda pushed out a number of variations of the K20A, unimaginatively named the K20A1, K20A2, K20A3, K20A4, and K20A6. The A1 was purely for the Japanese home market (JDM). The K20A2 first arrived within the United States below the hoods of Honda’s efficiency sedans, such because the Integra Type R, Civic Type R, and Acura RSX. The K20A2 pushed 200 horsepower for the second technology Civic Type R between 2001 and 2006. The A3 variant would possibly sound new and improved, however Honda downgraded the internals for cheaper manufacturing. The A3 and A4 are defanged variations meant for Honda’s extra sedate Accord and CR-V. The A3 is nice for about 160 horsepower and 141 lb-feet of torque, whereas the A4 is rated at 150 horsepower with 140 lb-ft of torque.

The K20A and its variants present a mixture of reliability, modification potential, energy, accessibility, and availability not discovered with another engine on this record, making the traditional K20A high canine on our record of Honda Ok-series engines ranked from worst to finest.

Watch This 1000 HP Toyota Starlet Drag Racer Shoot Fire Out Of Its Face

In stock form, the Toyota Starlet is a compact economy car, but this one is very different from the factory version. This is a drag racer with a rotary engine under the hood and a gargantuan turbo feeding boost to the mill.

The first part of the video puts the Starlet on the dyno. It has a raw sound at startup, which isn’t surprising given that the exhaust exits straight out the side of the hood, and there’s no muffler on the pipe. The sound grows to a scream at high revs. The microphone can barely capture the sound.

The Starlet’s whole front end comes off, and it gets onto the dyno. According to the YouTube clip’s description, the first run is in a low-boost setting. Still, the engine pumps out an impressive 975 hp at the rear wheels. The second run appears to be with more boost because the pull nets an output of 1,072 hp.

The next step is taking the rotary-powered Starlet to the drag strip for some tuning. There’s an issue with a clutch causing it to creep forward at the starting line and limiting the ability to launch the car. This means we get to see several runs, including how the Toyota shoots flames just before launching. It’s an impressive sight, especially at night.

Unfortunately, the various issues mean we don’t see a complete quarter-mile run from the Starlet. In addition to the clutch problem, the traction control setting is too aggressive, which cuts power off the line. The wheelie bar and parachute on the back suggest this car can put down seriously quick times when everything is working right.

The next step is to reduce the Toyota’s output when it launches. With over 1,000 hp at the wheels, the tires can’t handle the power. They spin off the line, which limits how quickly the Starlet can get down the quarter mile.

The Starlet was only available in the United States from the 1981 through the 1984 model years. Unlike many small hatchbacks, it was rear-wheel drive rather than the more common front-drive layout. They had a 1.3-liter engine, rather than this one’s rotary powerplant and big turbo.

SXSLIDE FULL PLATE FOR KTM 450: PRODUCT REVIEW

ktm 450xcf w sxslide

PRODUCT: The SXSlide Full Plate is a skid plate designed specifically for the KTM 450XCF-W. It is made from 1/4-inch UHMW plastic, which is both lightweight and extremely durable. It features deflectors to protect the water pump on the right side and a wing to protect the ignition side of the engine. Since this is a PDS machine, it does not need a linkage guard.

OUR TAKE: Mounting aftermarket skid plates can be a hassle, but the SXSlide Full Plate makes it easy. It uses KTM mounting points on the frame and a billet crossbar mount, simplifying the installation process. In terms of protection, it is significantly thicker than the stock skid plate, and the wings that guard the water pump and ignition do an excellent job in shielding these important areas.

In summary, the SXSlide Full Plate offers easy installation, increased protection, and a lightweight yet sturdy design.

Pro Circuit KTM300SX Exhaust: Product Review

Product: Pro Circuit faced a challenge with the 2023 KTM 300SX as many riders found the stock powerband to be too powerful. The bike has undergone significant changes for 2023, with the inclusion of an electronically controlled power valve and throttle-body fuel injection integrated with spark advance through the ECU. It also offers two maps accessible through a handlebar-mounted switch – a mild white map and a powerful green map. However, the two maps have different port timing, which was not possible with previous systems. Improving the exhaust system for a bike with so many variables is quite tricky. The Works pipe, manufactured by Pro Circuit for almost 40 years, is typical of their systems. It features a raw, unfinished steel exterior and uses all the original mounting hardware. We paired it with the Pro Circuit R304 stainless/aluminum silencer, which is part of the Shorty line, similar in length to the original but with a round shape instead of oval.

Our Take: The stock KTM 300SX can be quite challenging to handle, especially in the green map. It provides power comparable to a 450, but only briefly in the middle. The ramp-up is short before and after the power burst, requiring the rider to hold on tight and shift quickly. The white map offers an easier riding experience, but once you have experienced the sheer power of the more aggressive green map, it’s difficult to go back. With the addition of the Pro Circuit Works pipe and silencer, the KTM becomes more manageable in the green map without sacrificing power. The ramp-up now starts at lower RPM and the over-rev is slightly higher. In the middle range, it actually produces a little more power than the stock exhaust, while still being easy to handle. The exhaust note is slightly louder than the stock system, but it has a rich sound that we enjoy.

Racing against 450 four-strokes will still be a challenge for the 300SX. It requires a tighter grip, quicker shifting, and more precise throttle control. However, the Pro Circuit pipe is a step in the right direction, and we are impressed that it is already available for such a new bike. We also appreciate the raw steel finish, although it’s important to note that it requires regular maintenance to prevent rust (minimum with WD-40) and occasional cleaning with Scotch-Brite.

Price: $334.95 for the pipe, $171.95 for the silencer
