my main question is are thay compatible and is it just bolt on and go or whould some fabrication be reqierd and whould i see resonable power gains from this

 

There is really only 1 required mod. But the 2.4 bottom end isnt very strong stock. So its best to build it.

 

if thats the case might as well stroke it while its appart

 

Im building one right now

 

if you open your eyes and search you can find more then just the answer you want

2005/2006 are good til about 400 crank/350 WHP ish, give or take of course.

I know there has been some of our cavi bruddas who have gone hybrid. Not sure if the gains would be great. The LE5 head VVT is very tuner friendly.
