Maybe the biggest stumbling block is that Honda has switched engine management in a big way.

There is now a mass airflow sensor on the K20Z3. In the past, Honda had always used speed density for computing airflow, but ever-tightening emissions standards forced Honda to make the switch. According to Doug McMillan of Hondata, "The primary sensor for deciding the amount of fuel is now the mass airflow sensor. At part throttle and low engine speeds, it's highly accurate at measuring the actual grams per minute of airflow into the engine.

And yes, you're right, it was probably done for emissions reasons. Many other companies already use mass airflow.

That makes it a bit harder to just throw parts at it and get good results, but that didn't stop car owner James Norman from trying. John Grudynski, the owner there, quickly removed the engine and tore it all down. First up was the installation of the Eagle connecting rods.

Attached to the rods is a set of Supertech forged pistons that were hand-finished by HyTech to remove the sharp contours of the pistons dome. This helps with the flame travel across the dome and with cylinder filling. This compression ratio meant James would have to run some higher octane gas like halfhalf 91 octane, but he was cool with it.

The head was shipped off to Endyn for some clean up and a simple valve job. When the head returned, it was filled with a complete Supertech valvetrain.

Standard size valves were also installed. The head was finally ready for a pair of HyTech's Spec 1 cams. Initially, the Spec 2 cams were installed but after checking the clearances, Grudynski found the Spec 2's duration combined with the iVTEC cam timing he wanted to use in the midrange would cause a cam-piston collision because there was not enough valve relief in the prototype Supertech pistons production pistons will have deeper reliefs.

When building a piston-cam setup for the first time, this is a critical step and can't be skipped or you'll truly pay for it. A step back to the Spec 1 cams which are meant for stock valve reliefs and all was clear.

But James wasn't going to quarter-mile the car primarily, he was going to road race and high-speed race it-specifically the Silver State Classic.

The SSC is a top speed run held in Nevada twice a year. It's essentially a one state Cannonball Run. To help, some guys use an Accusump, others put in an S oil pump and others a dry sump system. HyTech's special oil pan baffle setup, combined with a modified pump, keeps oil all over these engines. Since the new K20Z3 engine has balance shafts, a good deal of space needed for baffles is already occupied.

To get it to all fit, Grudynski cuts down the block girdle section where the oil pump bolts down and also takes some material off the oil pump from a K20A2 or Z1, planting it on the Z3 engine. You can't use the Z3 oil pump with these modifications. With all the mods complete, Grudynski put the engine back in the Si and went to work on attaching one of his handmade custom headers.

This is HyTech's claim to fame.Amid news regarding the Coronavirus COVIDwe at HMotorsOnline want to prioritize the safety of our customers and staff by reminding you that there are no unscheduled walk-ins, pickups, or inventory browsing offered at this time.

All this together provided 2 liters of displacement. Some K20 versions were equipped with balance shafts. It knows how to use the valve mode to save fuel and the valve mode in case of dynamic driving. The intake valves size is 35 mm, of exhaust valves — 30 mm, and valve stem diameter is 5. The camshafts are rotated by a timing chain with the service life longer thanmiles of mileage. Valves should to be adjusted after every 24, miles. Valve clearances for the cold engine are the following: intake 0.

Here dual runner intake manifold and an EGR valve were used here for sending part of the exhaust gases back into the combustion chamber, which improves the ecological class of the vehicle. The K20A firing order is K20A engines were made in a wide variety of modifications and they were quite different. You can learn about the basic differences below. InK20 was replaced with R20A engines. Today, only one version is made, K20C.

The size of the throttle body was 62 mm. Inthe K20A engine received some upgrades. They installed a short RRC intake manifold, a 64 mm throttle body, improved the intake and exhaust head ports, installed reinforced connecting rods, and the compression ratio reached Now the VTEC system is triggered at 5, rpm instead of 6, rpm as before. As a result, the power increased to HP rpm, the torque is Nm 6, rpm, and the rev limiter is triggered at 8, rpm.

K20A1 — this version was described in the beginning of the article. The power was HP 6, rpm, and the torque was Nm 4, rpm. Here are the K20A2 cam specs: intake — 7. The compression ratio is slightly lower — 11, and the i-VTEC system is triggered at 5, rpm. The power was HP 7, rpm, the torque is Nm 6, rpm, and the rev limiter is triggered at 8, rpm. The size of OEM fuel injectors is cc.

The size of injectors is cc, i-VTEC is triggered at 2, rpm. A PPA intake manifold is used here, which is triggered at 4, rpm. K20Z1 is a modified version of the K20A2 engine.It's been more than a decade since Honda introduced its K-series engine family and a lot's changed since then. What was first met with resentment from Honda fans all-too complacent with B18Cs and LS-VTECs has developed into it becoming the engine of choice, especially for naturally aspirated hard-liners who pine for cubic inches and a modernized valvetrain.

Thirteen years later, though, and there's a whole lot of K-series engines to sort through, which can make choosing the right one downright baffling. You don't need to be told that not all K-series engines are the same.

Pick the wrong one and you might have been better off putting up with whatever B-series you've shunned as its predecessor. And none of this has ever been more true than now, especially when considering Honda's new fleet of K-series engines that care more about reduced emissions and fuel consumption than they do horsepower and upgradability. Follow along as we break down Honda's most popular K-series powerplants, from past to present. But first, a little history.

Following a year reign, the B-series was finally nixed and, in late, replaced with the then-unfamiliar K20A2, K20A3, and K24A1. The new platform's most notable differences when compared to previous four-cylinder Honda mills is its direct-fire ignition system, reverse layout, and clockwise rotation.

To improve catalytic converter light-off by positioning the engine's exhaust side toward the rear of the vehicle, Honda developed a clockwise-rotating architecture, which is a whole lot different than the decades worth of counter-clockwise-rotating engines the company's become famous for.

The number of K-series engine designations aren't few, but fortunately almost all of them can be traced back to Honda's initial K20A2 and K20A3. Unofficially known as performance i-VTEC, such engines feature Honda's most impressive valvetrain to date.

At the heart is something you've heard of: VTEC. Like its predecessors, inside the cylinder head lies Honda's hydraulically operated variable valve timing system. Simple and elegant, VTEC allows the engine to alternate between two different camshaft profiles depending on various conditions. Here, a specialized camshaft gear allows for continuously variable intake camshaft phasing throughout the RPM range.

Based upon all sorts of things that the driver needn't worry about, like camshaft position, ignition timing, exhaust oxygen content, and throttle position, a degree range of camshaft phasing can occur degree range on K24A2.

Much like VTEC, the camshaft gear is electronically controlled and hydraulically driven, resulting in reduced timing at idle and advanced timing at higher engine speeds, which increases valve overlap and power. The advantages up top span beyond the valvetrain. Performance i-VTEC engines also feature more optimally shaped intake and exhaust ports when compared to the B-series and larger ports when compared to other K-series engines.

On the intake side, they form a nearly straight path. On the exhaust side, they're free of the humps typically found within B-series ports. K-series engines also benefit from sophisticated roller rocker arms, which reduce valvetrain friction and allow for all manner of billet camshafts.

This is in stark contrast to older Honda engines that feature standard, pad-style rocker arms. Down below, every 2. Also known as a square design, such engine architectures are a good compromise between decent low-end torque and adequate top end power. The 2. In terms of crankshafts, each is forged from high-quality steel, but only performance i-VTEC versions feature a fully counter-weighted design. Performance i-VTEC engines also feature under-piston oil squirters for increased cooling, stronger connecting rods and, generally, higher-compression pistons.

Although engine geometry and ancillaries such as intake manifolds, throttle bodies, and exhaust manifolds may differ between them, they all share more in common than not and make up some of the most desirable K-series engines.

Compared to economy-minded K-series engines, the K20A2 features larger intake and exhaust ports, a higher, As is the case with all performance i-VTEC engines, a stiffer, cast-aluminum oil pan is also incorporated that increases overall rigidity. As Acura performed its mid-model refresh on its RSX, a revised K20Z1 was placed underneath its hood for the model's final two years of production.The Honda K-series engine is a line of four-cylinder four-stroke car engine introduced in The engines use a coil-on-plug, distributorless ignition system with a coil for each spark plug.

This system forgoes the use of a conventional distributor-based ignition timing system in favor of a computer-controlled system that allows the ECU to control ignition timings based on various sensor inputs. The cylinders have cast iron sleeves similar to the B- and F-series engines, as opposed to the FRM cylinders found in the H- and newer F-series engines found only in the Honda S Similar to B series, the K-series car engines have two short blocks with the same design; the only difference between them being the deck height.

K20 uses the short block with a deck height of mm where K23 and K24 block has a deck height of The VTEC system on engines like the K20A3 only operate on the intake cam; at low rpm only one intake valve is fully opened, the other opening just slightly to create a swirl effect in the combustion chamber for improved fuel atomization.

At high rpm, both intake valves open fully to improve engine breathing. Similar to K20A3 and K20A1. From Wikipedia, the free encyclopedia. This article is about the Honda engine. For the Rover engine series of the same name, see Rover K engine.

The rental car was great and very fuel efficient. Iceland is planet earths best kept secret. I hope others will consider cooling off a little in the middle of summer and visit Iceland.

The cell phone given to us was very helpfull, especiay because we did had problem with our car and it was very convenient to handle it with the phone we had.

Material we got - was very helpfull. We did a custom self guided tour "South Iceland at Leisure" (2 days in each location) through Nordic Visitor and had the time of our life. Alexandra customized our tour after we told her our dates, price, wants.

The vacation was incredibly smooth and well organized. Reykjavik was fun but we were excited to take off and see the rest of the country. The landscape was incredibly varied and the natural wonders (waterfalls, lava tubes, fjords, black beaches, glaciers. We are very active vacationers. Our favorite hotel was the Volcano Hotel near Vik. The only wrinkle we had the entire time was the Hotelfoss Skaftafell. They have very few double bed rooms and we were there over a holiday weekend and so were initially put in a very small twin bed room.

The Skaftafell area is GORGEOUS if you are looking for amazing nature, just expect the hotel (there is only one.

It's worth the stay though, Svinasfelljokull glacier climbing was definitely one of the most fun things we did. An absolutely amazing trip with excitement at every stop we made.

We loved every second and have fallen in love with Iceland. Thank you so much Nordic Visitor for the fantastic trip. This was an excellent tour, the planning was unbelievable and the tour information excellent. We could not find any faults with the services from any those involved in making our tour such a great memory.

The only critisium is we should have planned a few extra days. This trip was everything I hoped for. I booked this trip - 5 new countries - as a celebration of my 50th birthday.

Everything that Nordic Visitor and Jennie did was fantastic. I got sick on the first day but Jennie helped me with the missed tour and smoothed everything out. Our hotels were great and in great locations. All of the instructions in the welcome package were spot on. Randy especially loved all the marked maps. Each city map looks very well-worn now because we carried them everywhere to plan our next move all day long. We are very active and were covering 12-15 miles on foot each day.

The maps kept us on course and let us know where to head next. When we stopped for dinner on the way home from the airport back in LA, I asked Randy what he would change about the trip and his answer was, "Nothing.
