[MOODY]

1705885 2.5/2.7

The bottom end has the following numbers

1289575
25 6k 1
23016837

2.5

[MOODY]

What cars it out of ? Year etc as I've tried to connect a late loom to injectors and it's not the same. A spec on engine would be good

Its a low comp 8.8:1 cat prepped M20B25 engine from a post '88 car.

As others have decoded, the key part is the "25 6k 1" part.

This means 2.5 litre, 6-cylinder, designed for Katalyser (meaning low-compression).

The number that follows that is the build number for that engine.

Thank you for the info

Just need to find out which ecu to use and wiring loom

[Brianmoooore]

Late M20 loom should fit.
The 2.7 stamp appeared on the head casting, along with 2.5 after the introduction of the US Super eta E30.

Does not fit the injectors

[Brianmoooore]

In what way? Spacing? Design of plug?

[MOODY]

Design the engine had a part loom on it but cut, the injectors ain't straight plus it was a wire loom that was on then unlike the later loom which has the caseing on it
