2L LSJ to 2.4L
 
Has anyone done any research into this? Using the 2.4L's crank in our LSJ?

I know bolt patterns are different. You would also be taking a shot in the dark as far as bore spacing.

On a positive note, the reluctor wheel for the crank sensor has the same number of teeth, even though the sensor itself is different. :lol:

2.4 has different bore and stroke, I believe, but isn't the 2.2 just different stroke? Seems like that would be much easier to pull off, but I have no idea about bolt patters, sensors, and all that shit. :)

That's why i want to do the swap. A 2.4L LSJ would put out about 30+ more pounds of torque. I'm going to look into it.

What's the big difference between the LSJ head and the 2.4L head besides the VVT? Could i bolt the whole supercharger/intercooler assembly to a 2.4L head? What about just using a 2.4L shortblock with a LSJ head?
