Which cars have k20

Of course with all of these different variants of the K20, there were different horsepower and torque ratings. Most of the power differences come from different compression ratios, tunes, and cylinder head design.

In any internal combustion engine, the cylinder head is the key to unlocking power. Just like the B-Series, D-Series, H-Series, F-Series, and pretty much every Honda engine out there, the K20 has a pretty big aftermarket and has been proven to be quite a good little motor. Of course, the typical intake and exhaust modifications will gain power, putting a K20A2 around whp, which is pretty good considering a naturally aspirated B-Series can have a difficult time reaching whp without quite a bit of modification.

The K20 has more room for naturally aspirated power than the B-Series, to put it simply. When it comes to high horsepower, forced induction K20 engine, there is one big thing that holds this engine back: the transmission.

Of course, there are plenty of Honda guys out there pushing more power than that on the stock transmission, but the danger area starts around whp. The life of the transmission depends on how often and how hard you launch the car, and how hard to shift gears.

Back to the point at hand. With boost, you can safely run about whp for an extended period of time. With a built bottom end you push power upwards of whp before you need aftermarket sleeves in the block. They have a valid point, especially if you are looking at naturally aspirated builds. Unfortunately, your stock K20 will not be able to match. The K20 Civic was next, so it was fun to see the second run. The Civic was able to outrun the Lambo even though it had less horses. The Honda Civic has blue flames coming from underneath its hood.

The third and final run pits the Lamborghinis against the B18 Civic. The little hatch has a better pull this time. Load More. Car Tuning , Engine , Honda. Share this. Share 0. Tweet 0.

This is the most established of K-series engines and is based off an all-aluminum block and DOHC with a valve cylinder head.

Unlike the economy-focused K20A1, this added uprated camshafts, a PRB intake manifold, alongside larger intake and exhaust ports. Its compression ratio was slightly lower at Despite looking almost identical to the K20A2, the changes were mostly internal in favor of improved economy figures. This model was capable of producing just hp or even less in the 2.

Compression was down to 9. With Acura performing a mid-model update on its RSX, the updated K20Z1 was chosen for the final two years of production. There is very little difference between this engine and the K20A2 other than slightly improved camshafts, a higher-flowing catalytic converter, and larger intake and exhaust. This provides an additional 10hp. This engine was a replacement for the economy K20A1, featuring a new longer-runner intake manifold, restyled camshafts, and drive-by-wire mechanism.

After Honda ceased production of the original K20 engine in , production was put on hold for some time until its rebirth with the newly-designed K20C1 engine in Despite being built in Ohio, this turbocharged variant was only available on the European market and enabled Honda to produce a far more powerful engine. With a compression ratio of 9. This power was also achieved by adding a new lightweight crankshaft, forged connecting rods and modified pistons.

It also gained a new cylinder head with a direct injection system and an i-VTEC system is integrated for the intake and exhaust valves. After improving the intake and exhaust head ports, a single-scroll MHI TD04 turbocharger was added and produced 1. After the impressive output of the K20C1, Honda returned to their economy range with this naturally aspirated version of the K20C.

This time an i-VTEC head with a direct injection system and improved combustion chambers was used. It used the same lightweight crankshaft from the K20C1 with modified pistons, providing a compression ratio of Based on the K20C1, but with a This engine was produced for the Chinese domestic market and is very rarely found.

This was again based on the K20C1 for the U. With some models producing hp K20A6 , others were capable a far more impressive hp at 6,rpm in its stock turbocharged form K20C1. Interested in the history of other cars? This is far easier to achieve in the K20 than it is in the B18, which requires more extensive mods to hit the whp ballpark.

By simply fitting bolt-on mods such as an RRC intake manifold, an FD2 throttle body, a cold air intake system, header, a 2. With even further mods you can also achieve over 9,rpm. This will give you 2. With larger pistons, the compression ratio is then capable of being increased to
