'We look at the best mods for this popular Nissan engine.'
- I have a 98 Frontier 2.4L Ka24de. Car wont start and I suspect timing. I have the valve cover off and can view the two idler sprockets. The upper timing chain has three yellow colored links separated by an equal number of links. The confusion is that both idler sprockets have two engraving marks with a little less than a 90 degree separation.
- I followed the timing like the nissan service manual says to do the timing in the distributor. Now when I crank the engine, my car wants to turn on but it never runs. I have spark and fuel but its like they are not firing where they are supposed to be. If you figure out the position of the cam angle sensor in the ka distributor that would be great.

Taking the KA24E as the origin, Nissan have made revisions and created a fantastic block, that responds well to tuning and has plenty of potential.
KA24DE has a higher 6900 redline* than the 1988 KA24E 6500rpm, with the main differences being that the KA24DE has a double overhead camshaft and other revisions including a better knock sensor, heavy duty main bearings and revised oil pickup.
The Nissan KA24E is a 2.4 l (2,389 cc, 145.79 cu-in) straight-4, four-stroke cycle gasoline engine from Nissan Ka-family. The Nissan KA24E motor was produced from 1988 through 1997. The Nissan KA24E engine has SOHC (single overhead camshaft) design with 12 valves (3 per cylinder).
Serial number garritan personal orchestra torrent 2. The KA24DE has 4 valves per cylinder, against the 3 of it's SOHC brother.
*The oil feed was revised, and rpm was limited to 6900rpm, then this was cut to 6400rpm to facilitate the implementation of the Nissan 240SX's cam profile and intake design around 2004. Some SUV versions of this engine had a redline of 6100rpm.
Some blocks were made in Mexico for models destined for the US market. Then JDM market car engines were built in Japan and there were significant differences between these, despite bearing the same engine code.
Ilividsetup. The Japanese engines were lighter, and had larger diameter girdled main bearings and were generally tuned to higher RPM and power levels. The oil feed and camshaft differences have also been noted.
The Mexican blocks were heavier as they were made from cast iron, and as such tolerate higher power figures than the JDM engines. So although the engine was built for trucks there is probably more tuning potential and adding more power is unlikely to break anything!
The dipstick location is the best way to tell the engines apart, as JDM engine dipsticks were located in the center of the engine, and the Mexican engines has the dipstick located to the rear.
Parts are not necessarily interchangeable between the two versions so please check carefully before ordering upgrades, particularly camshafts and anything to do with the oil feed and pickup.
Typical power outputs varied by year, and by application. SUV's tended to be built for Torque and reliability by way of a different compression ratio and cam design.

Most of our visitors have this engine in the 240SX so were are going to look at tuning this block with 'track day sports car in mind'.
If you have a heavy truck and are looking for more power then this article will cover the basics, but you'll be looking for more low end torque, and probably not after a high revving engine.
Camshaft choice is the thing that differentiates the power band, along with head work (gas flowing, porting and polishing).
With NASP only mods you'll probably gain around 20-30bhp, when you add forced induction you can be looking at an extra 100bhp or more!
KA24DE Tuning Tips
Typical stage 1 mods often include: Sports exhaust, Remap,Panel air filter
Typical stage 2 mods often include:Fast road cam, high flow fuel injector, Ported and polished head, fuel pump upgrades.
Typical stage 3 mods often include: Engine balancing, Competition cam, Internal engine upgrades (pistons/head/valves), Adding or upgrading forced induction (turbo/supercharger).
There are a few good quality turbo kits around for the KA24DE and you should hit power figures around 380hp to 400hp. The oil feed drain lines need uprating, you'll need an intercooler and timing adjustments.
Fuelling would also be a problem for a turbo kit so you'll need better injectors, rated to flow what you've tuned the car to handle and an aftermarket engine management kit.
We favour the GT3071R Dual Ball Bearing OR GT3076R Dual Ball Bearing turbos, they spool up nicely on this engine and make for a good top end power boost without too much low down lag. Internet download manager cracked version. 4500 rpm is where you really feel these turbos spooling up and where power stays flat on the NASP engine through to redline you'll get a big pickup around 5000rpm on the turbo setup.
The twin scroll turbo is the route to go if you are adding forced induction to the KA24DE.
Clearance in the engine bay can be an issue with bottom mounted turbo manifolds, so give some thought to adjusting the floorpan or the downpipe to accommodate this. Power steering brackets can also get in the way and may need grinding back.
The KA24DE was replaced in 2004 with the 2.5L QR25DE
Regular maintenance & weakspots on the KA24DE
Valve adjustments should be checked every 1200 miles.
Piston and crank are forged, and pretty solid, as such the engine can take quite a bit of punishment. It is thought to be bulletproof, subject to proper servicing and in particular regular oil changes.
Replacing the outdated mechanical spark timing with a proper electronically managed solution will make your future tuning mods easier.
Pistons are good for power figures around 260hp but going beyond this it makes sense to uprate the pistons, and crankshaft. We've heard of some running power figures of 320hp on stock internals as they are so solid, but we would worry about reliability.
Fuelling can struggle at higher power figures, as with most tuning projects your choice of injectors and mapping is vital.

The KA engines were a series of four-strokeinline-fourgasolinepiston engines manufactured by Nissan, which were offered in 2.0 and 2.4 L. The engines blocks were made of cast-iron, while the cylinder heads were made of aluminum.
Despite their large capacity, this motor was not equipped with balance shafts.
When used in the passenger cars both versions of the KA24 used a crankshaft girdle, as opposed to individual main bearing caps. In the Nissan Hardbody and Frontier applications a crank girdle was not used.

KA24DE[edit]
KA24DE Engine in an S14 240SX
The 2.4 L (2,389 cc) KA24DE was used in many Nissan cars and trucks. Adobe acrobat xi pro crack. Most KA24DEs bound for the US were built in the city of Aguascalientes, Mexico, with the exceptions of the 240SX, 1994-97 Altima (re-badged Bluebird SSS), and the U13 Bluebird released in Australia with FWD configuration, which were manufactured in Yokohama, Kanagawa, Japan.[1] The KA24DE is very similar to the KA24E. The KA24E is SOHC with three valves per cylinder actuated by rocker arms, and the KA24DE is DOHC with 4 valves per cylinder and shim-over-bucket valve actuation. 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 (not interchangeable between Japanese and Mexican blocks), different oil pickup (front pickup on Japanese block and side on Mexican block), dipstick location (toward the rear of block on Mexican and mid block on Japanese) and piston oil squirters. In addition to the increased power and torque, the KA24DE has a higher redline than the KA24E.[citation needed]
KA24DE-A is an Altima specific model of the KA24DE. The head and block are non-interchangeable between all other models and are uniquely cast for front wheel drive operation.
Differences in the Japanese block to Mexican are also present. The Mexico blocks (all DEs except those found in the S series) implemented a distributor and oil pump drive similar to the L series; from the crank nose. They also used a single row chain for the upper timing assembly without valve cover mounted guide. In addition to this, they removed the rearmost cam journal in the Mexico head. The crank rides on individually capped bearings with a slightly smaller diameter than the Japanese block, with shorter, slightly lower compression pistons in cylinders that have thicker walls than the Japanese DE. They retained the knock sensor and piston oilers.
