Only just curious....is itcompatible toswapin a4.3 into a earlier19994.0 car? Other then the physicalswap itself? Does the 4.3 share the same harnesses fasteners as a 4.0? I assume there would bedifferent ECM Calibrations. Is it a different generation of ECM for the 4.3?

I know anything can be made to work with the right effort. But had not seen anyone post that swap for a replacement candidateand a smallupgrade at the same time. Other then the Bore/Stroke differences of the two. What else changed that would make it difficult?

Thanks for your thoughts in advance.

 

No need to respond....I found the some good answers.....Looksto melike 4L cars will stay 4L cars! To much Jaggauge differencesto change and re-fit.

 

and it's a 4.2 liter not a 4.3

 

Well....once the valves smack the pistons it could possibly become a 4.3? lol

 

Were you planning on using the Aston Martin 4.3 version of the AJ-V8 (that is a bored out version of the original 4.0 rather than the stroked 4.2 jaguar version of the same engine).

I am asking because I am wondering how much commonality there is between Aston Martin and Jaguar ECUs and if you inadvertenly found something out?
