The main cap girdle is very substantial in order to enhance the stiffness of the crankcase assembly and prevent crankshaft whipping. As a rule of thumb add 20% capacity when buying an injector, helps cope with injector deterioration and allows you some spare capacity should the engine need more fuel. The shape and flow rate of the Air Intake manifolds can make a big difference to to fuel mixing and power on the K20. From outside the UK +44 1708 866 609, Unit 5, Cliffside Trade Park, H section with detailed CNC machining to optimise weight and strength, Radial truss small end to optimise weight and strength.

The best modifications on an engine are in our opinion the ones that give the best value for money. Large upgraded turbos commonly experience low end lag, and small turbos spool up really quickly but do not have the peak rpm torque gains. The cylinder head is torqued down to the correct settings with an electronic torque wrench. Engine disassembly is normally a messy job! You can leave a response below or join our forum to discuss this article and car modification in detail with our members. Very light weight reduces reciprocating mass. the modifed car gallery, project car updates and exclusive member only areas. And one of the best bang for the buck modifications that can be done is a K-Swap. Copyright © 1995-2020 eBay Inc. All Rights Reserved.

Thurrock, The engine build specifications are recorded to ISO9001 standards in case we need to rely on them at any time in the future. Such was the success of this block it has been revised and tweaked and was released with power upto 306bhp from the factory, with plenty of leeway and room for the tuner to make more and many reporting the blocks are safe to 400hp (but your mileage will vary depending on the block and version you have, the R versions are much better built). The crankshaft and main girdle has final fitment so it’s time to measure the big end bearing clearances. The most popular K20 injectors we've found people using are.... You only need to to replace your exhaust if your current exhaust is actually creating a restriction. The front cover is now safely installed too. Xylan skirt coating improves bed-in and reduces frictional losses. Comments are used to improve the accuracy of these articles which are continually updated.

We hope you enjoyed reading about this Honda K20 engine build. It’s best practice to check all bearing clearances. This engine is on its second cam chain, and even this one is approaching the end of its service life. {"modules":["unloadOptimization","bandwidthDetection"],"unloadOptimization":{"browsers":{"Firefox":true,"Chrome":true}},"bandwidthDetection":{"url":"https://ir.ebaystatic.com/cr/v/c1/thirtysevens.jpg","maxViews":4,"imgSize":37,"expiry":300000,"timeout":250}}, 90 Day Warranty Factory Parts With Fast & Free Shipping. There is a mod called the K FRANK, where you fit an Accord 2.4 bottom end with a type R head on the top. The K20Z was 2005-2015 and the K20C is stilll in production today.

Save racing for the track and keep the roads safe. To keep us running PLEASE Donate here. The valves have been lapped in and installed with Toda racing valve springs. The K20Z4 was related to an S2000 engine so dropping in the crank from the S2000 would give good power gains (research your engine and donor engines carefully before doing this). The main cause of the heavy oil consumption was worn valve guides. ECU remapping It is vital to any engine modification project to feed more fuel and air into the K20 engine. Sign up now!!!

This was quite an impressive achievement, and shows how good the K20Z1 block is.

It’s power potential is practically limitless ( your funds will be the limiting factor ) while it’s reliability is amongst the best. There was technically no A1 version - essentially it's still a K20A3 but a lower spec compression to handle the turbo! Track day insurance However you will find an engine has weakspots so discover these limitations and fit better pistons and crank to cope with the power. Cosworth recommend a bore clearance as low as 60 microns, so any tight spots may lead to a catastrophic seizure. It's not unheard of mechanics spending a loads of money on turbo upgrades on the K20 only to watch the engine literally blow up when it's used on the roads. For me, there’s no better engine to shoehorn into an older Integra or Civic then a K20 or K24.

The latest tuning products to hit our shelves.

The engine timing and injectors and fuel pump also have a large bearing on the torque gains you'll achieve. Interestingly it's worth noting that the K20A3 VTEC only works on the intake but on the K20A2 it operates intake and exhaust. Bear in mind some of these engines were extensively modified so these are not the only parts added. It’s been a busy day for this TDI/Cosworth engine, so it’s time to get tucked into bed for the night. The best modifications on an engine are in our opinion the ones that give the best value for money. The inside of the crank case prior to installation of the crankshaft. (All car owners of all ages and from all countries are welcome).

Detonation is evidenced by the appearance of erosion of the piston and cylinder head material. Something went wrong. Cosworth Race Series main bearings are installed, the crankshaft is fitted to measure the clearances. This page was last updated: 22-Oct 12:59.

The rocker arms and shafts are installed ready for some Toda Racing A3 camshafts. Significant gains can be made from camshaft upgrades. Help us improve, leave a suggestion or tip. The Spec R engine had a lighter flywheel, high compression pistons, stiffer valve springs and longer camshaft durations. The camshaft is usually the first thing to show up problems when the wrong grade of oil is used. The valve train is in great shape, and is testament to good and regular servicing. We’ve selected Cosworth racing pistons for this Honda K20 engine build application, which have the following features: Cosworth pistons are available in 86.00mm / 12:1 CR , 86.25mm / 12:1 CR and 86.5mm / 12:1 CR and can be bought from these links. This engine has done 175,000 miles in total which is 145,000 very hard miles (every day use and track days (including Nurburgring)) in the two years since we tuned the ECU to wring every last bit of power out of her. The standard pistons show a build of carbon deposits as a result of heavy oil consumption. Please drive sensibly we do not endorse speeding or racing on the public highway or driving recklessly or in a manner than could endanger life or property. Accumulator groove improves compressing ring sealing under high cylinder pressures. If your motor is already turbocharged, tuning parts are giving better power gains and we find turbo engines are made with harder and stronger components. I do not charge you to access this website and it saves most TorqueCars readers $100's each year - but we are NON PROFIT and not even covering our costs. We’ve seen stretched chains cause unwanted valve timing variations, and even jumped teeth.
