Inliners International Forums General Discussion Hi Performance What year did 4.2 go to 295 hp?

and what was the change that gave it more horsepower? It looks like pcmforless has hacked the factory ecu, but why would the speed limiter not be hacked? I will be embarrassed if my xke is speed limited to 105? I'm not ready to do the megasquirt yet, would like to get it up and running besides, 295 hp is alot more than the factory stock (200 real) I haven't bought an engine yet but I like the 4.2 so far, thanks skip

2006

Bigger intake cam
Bigger intake valves
bigger exhaust port
More compression

Most likely a calibration change too

The head is the biggest change.
