In my quest to find out more about my engine, i have the numbers on my cam and head. they are as follows Cam has "24H" cast on it midway along, as well as "A" in a white marker. the head has "G7S4 FF" on the side of it, and also "M4". it also has BOM23 written in white marker along the cam pedestalls area, although i assume thats not from the factory. any info on what engine these numbers apply to ie the 147kW version or the 150 kW version, would be much appricieated. as stated before the reason is my car had a recon engine at 218,000km, and i have no idea what model it came from (another KE or??) i understand my KE tune ECU will limit power, as mine is aussie made i assume its the same as your KE tune, or did us kiwis get a different tune?? i dont have EGR. cheers for help.

There should be a series of numbers on the end of the camshaft. The part number followed by a space then another single digit number.
It's that single digit number that you want.

4 = 150kW pre TJ2
6 = 155kW post TJ2
7 = Ralliart

The above applies to 3.5L 6G74's, I don't know what cams the 6G72's run.

yeah i think it must be under the end cover so ill have to take that off and take a look.

i understand my KE tune ECU will limit power, as mine is aussie made i assume its the same as your KE tune, or did us kiwis get a different tune?? i dont have EGR. cheers for help.

KE/KF 3.5's dont have EGR over here either.

It came along in the KH/TH 3.5's.
