Nissan KA24DE engine reliability, problems and repair
KA24 appeared in 1988 as substitution to Z24. The first version of the engine was KA24E. It used 4-cylinder inline cast-iron cylinder block with cylinder diameter 89 mm. Inside forged crankshaft was installed with 96 mm piston stroke, and also 165 mm forged connecting rods. On top it had aluminium cylinder head with one camshaft (SOHC) and 3 valves per cylinder, two intake and one exhaust. Inlet valves are 34 mm in diameter, while the exhaust are 40 mm. KA24E camshafts: duration 240/248 deg, lift 10.38/10.38 mm. KA24E rev limiter is set on 6,500 RPM.
KA24E for SUV uses camshaft with duration 232/232 deg, lift 9.7/9.7 mm. For this engine redline is lowered to 6,000 RPM.
Stock injectors KA24E are 260 cc.
Later, since 1991, head with two cylinders (DOHC) and 16 valves, 4 valves per cylinder, was applied. Inlet valves were 36.6 mm in diameter, the exhaust – 31.3 mm. These engines were called KA24DE. In contrast to KA24E, KA24DE engines have new oil pan and oil jets, modified pistons and crankshaft with compression ratio 9.5. On models for SUV compression ratio is reduced to 9.2 and 9.3. Early KA24DE (till 1994) used camshafts with duration 240/248 deg, lift 8.9/9.32 mm. It let the engine whirling to redline 6,900 RPM.
In 1995 Nissan 240SX S14 was equipped with such cams: duration 232/232 deg, lift 8.73/9.06 mm, and they were used until the car was discontinued. The same year intake manifold was modified. It reduced rev limiter to 6,400 RPM.
For the rest cars camshafts 240/248 remained, and then in 1997, intake cam was changed for the new with duration 232 deg. Stock injectors KA24DE are 270 cc.
The version for SUV and large cars used long length intake manifold and camshafts, meant for low-end to the mid-range torque. Such engines had 6,100 RPM rev limiter.
KA24DE engine has no hydraulic lifters, therefore from time to time it is necessary to adjust the valves. Valve clearance on cold engine: inlet and exhaust 0.28-0.36 mm.
The engine has timing chain, which should be changed utterly rarely, usually every 180,000-200,000 miles of mileage (300,000 km). KA24 firing order is 1-3-4-2.
Along with KA24DE, 2L KA20DE was produced.
In 2004 KA24DE engine was substituted for more modern 2.5L QR25DE.

Nissan KA24DE engine problems and malfunctions
This engine belongs to the simple, reliable and durable Japanese engines of the 90-s. You need just to serve it regularly and use high quality engine oil. On the front-wheel drive of the car it is enough to press the oil pan a little and the oil pressure may fall. If it has happened, then you need to take off the oil pan and to check the state of oil receiver pick up pipe.
Also you can easily destroy KA24DE, using low-quality engine oil. Boosey hawkes edgware clarinet serial numbers list. If your timing chain starts making a noise, it is the sign.
Yet KA24 engines have high fuel consumption, do not be surprised with it.
As for the rest, their reliability is on the highest level.

N/A Build
To gain some power for cheap, you need the most aggressive OEM camshafts. But first of all, repair your engine, it may be old and worn, put your engine in order.
After that purchase KA24DE stock cams (248/248), cold air intake, 4-2-1 header, 2.5 inch straight pipe exhaust system, lightweight flywheel and JWT ECU. Install all these performance parts, adjust ECU and you will get ~20 HP more.
You may gain about 200 WHP, but for this you should buy Xcessive intake manifold, VK45DE throttle body (90 mm), cams 272/272, adjustable cam gears, valve springs and do head porting. And also do not forget buying forged pistons (CR ~11) and connecting rods, main and rod bearings, SR20DET fuel injectors (370 cc), 4-1 header, 2.5 inch straight pipe exhaust system. Gaining more than 200 horsepower is possible upon installing Suzuki GSXR 1000 individual throttle bodies and increasing compression ratio.
Also it is possible to implement something similar using KA24E engine. But in this case you would have to do maximal port and polish, install enlarged valves, and after all, the power will be lower, comparing to the same tuned KA24DE.
Also stroker kits for KA24DE are available. They have crankshaft with 102mm piston stroke, 165mm connecting rods and 90mm pistons. This kit will let increasing displacement to 2.6L, but it will reduce max RPM. Such kits are rather expensive, it would be more efficient to make KA24DET.

KA24DET
This is the most proper way to increase the power of the engine, as stock internals are quite firm and keep the boost easily.
To build KA24DET, you should buy T3/T04E 50 trim 0.63 A/R turbocharger, turbo manifold, downpipe, intercooler, piping kit, Z32 MAF, wideband O2 sensor, wastegate, BOV, Walbro 255 lph fuel pump, fuel injectors 550 cc/min, Clevite main and rod bearings, MLS head gasket, 3” performance exhaust system, JWT ECU.
This will be enough to gain about 350WHP at 16 psi (1.1 bar).
Using SR20DET turbocharger, it is possible to obtain a quieter setup on 250+ WHP. It is enough to drive in the city. Using big turbocharger you can gain about 500 horsepower on stock pistons. However, it is advisable not running a risk and using forged pistons (CR= 8.5-9) to make your KA24 really powerful. Also it is better to do head porting, install cams 264/264, valve springs, big valves, etc. In the upshot, for your KA24DE to bear 500WHP ++ and stay reliable, you will have to spend a lot of money indeed.

If you’ve been around the drifting scene, then you’ve probably heard of the KA24DE engine. It’s the engine that all Nissan 240SXs in the U.S. used. You’ve probably heard that it came from the Nissan Hardbody truck. The KA24 was designed to replace the extremely outdated Nissan Z engine. Although this engine doesn’t use any innovative technology, it does have a cult following like other Nissan engines. In this short article, we’re going to cover everything you need to know about the KA24DE. You can find additional information on the KA24 Wikipedia page.
KA24DE: Engine Basics and Specs
The KA24DE is a 2.4L inline four-cylinder engine that uses an iron cylinder block with an aluminum cylinder head. Part of the reason Nissan used an iron cylinder block was to save money. The engine was intended for use in light trucks and SUVs, so weight saving wasn’t a significant concern. Early versions of this engine used a SOHC design with three valves per cylinder. Even with its relatively large displacement, the KA24 did not implement balance shafts.
Later versions of this engine used a DOHC design with four valves per cylinder which increased power and efficiency. Oddly enough, Nissan decided to use a shim-over-bucket configuration for the valve train instead of rocker arms. Intel atom d410 motherboard drivers for mac. The KA24 uses a Hitachi sequential electronic fuel injection system. Nissan configured some KA24 engines for front wheel drive vehicles.

Cars That Came With the KA24DE
Nissan put the KA24E and KA24DE in a variety of different products through their life cycles. Some engines were destined for light duty pickup trucks and SUVs such as the Nissan Hardbody or Nissan Xterra, but the KA24 is best known for its appearance in the 240SX. It makes sense just to adapt the engine for multiple platforms rather than creating an all-new engine.

KA24DE: Known Problems
Nissan Ka24de Timing Procedure Diagram
Just like any other engine, the KA24DE has a couple of known issues that are common. Fl studio 11 registry key download. The distributor is known for failing on earlier versions of the KA24. Another prevalent issue is a rattling timing chain, which occurs when the timing chain gets loose from age and begins to rub against the timing chain cover.
Supposedly the alternator fails more than many other vehicles, but we are not able to verify this problem. The last issue is the valve cover gasket which is known for leaking, which is mostly due to the bolt pattern and design of the valve cover. It’s a pretty quick and easy fix, but it is a common occurrence.
KA24DE: Tuning Potential
Nissan Ka24 Timing Chain Marks
Thanks to the massive explosion of drifting, the 240SX has become the most popular tuner car in the world. Although many people upgrade to the SR20DET engine, many stay with the KA24DE because of its larger displacement. A naturally aspirated built can reach up to 200whp (230bhp), but it isn’t cheap. This kind of build requires full bolt-on, ported and polished head, bigger cams, and possibly a higher compression ratio.
Karan kundra wife. Many people prefer the turbocharged route as it’s relatively cheap and makes pretty decent amounts of power. Although many people use an eBay turbocharger or the SR20 turbo, the better option is to use a quality turbo. Something like a Garrett GTX2867R would easily make 400whp or more. If you want excellent throttle response and lot’s of low-end torque, a Borg Warner EFR turbo would be a great solution. Unfortunately, the stock bottom-end isn’t strong and can only hold up to about 350whp. If you’re looking to go for big power, you’ll need a forged rotating assembly. If you end up dumping that much money into a KA24, you might as well swap in a 1JZ/2JZ or RB engine which will make way more power while also being more reliable.

There seems to be quite a lot of confusion about the differences between the KA24E and the KA24DE. As you may expect, these engines are very similar, but there are a few fundamental differences that separate these engines. The most significant difference is the cylinder head.
The Ka24E was a single overhead cam engine with just three valves per cylinder, and the KA24DE was a dual overhead cam engine with four valves per cylinder. If you didn’t already know, the biggest power gains of any engine are found in the cylinder head. It was mostly the trucks that use the KA24E, but the 89-90 240SX also used it. Luckily, the 1991 – 1998 240SX used the KA24DE.

Design improvements of the dual cam engine include the use of a knock sensor, larger diameter girdled main bearings in the Japanese block, different oil pan, different oil pickup, dipstick location, and piston oil squirters.
