It will, but it is way more work than you are going to want to do. Lots of conversions. It is better and cheaper to just buy a used ka24de, you can find the, quite cheap these days because people pull them to install sr20det.
Nope. 240s only have a single and a dual cam motor both are fuel injected.
1990 is ka24e, single overhead cam, 1991 is ka24de, dual overhead cam.
A block from an early 90s single cam engine is generally not compatible with a 95 dual cam head due to differences in mounting points, oil passages, and overall design. The architecture of the two engine types differs significantly, which can lead to issues with fitment and performance. It's best to use components that are designed for the same engine generation to ensure compatibility.
For an engine swap from a single cam automatic to a dual cam manual in a '89 240SX, you'll need the dual cam engine (SR20DE or KA24DE), a compatible manual transmission, and the necessary transmission mounts. Additionally, you'll require the manual transmission crossmember, clutch pedal assembly, and a new ECU that matches the dual cam engine. Don't forget to gather the wiring harness and any sensors or components specific to the manual setup, as well as fluids and gaskets for installation.
It will fit if you cut it but as-is it will not attach to the throttle body. The 1989-1990 240's have the KA24e (single cam) and the 1991-1994 240's have the KA24de (dual cam) the throttle bodies are in different positions.
The 89-90 SOHC (single over head cam) has one. all other DOHC (dual over head cam) have 2. This is years 91+
it has a ka24 2.4l dual over head cam
The SC and SL used the same type engines. There were two available; the single cam was in the SL1 and SC1. The dual cam was in the Sl2 and SC2. All of the dual cam engines are interchangeable. All of the single cam engines were interchangeable.
dual band
You can add a single RAM block.
It is a dual action revolver
