2.4l Ecotec
Thursday, June 21, 2012 10:48 PM
Just curious why I do not see anyone swapping a 2.4l ecotec in there cars. I am assuming it would be a direct swap from a 2.2. Just curious that is all. Seems like it would be a better bang for your buck to all the 2.2l swappers. I would think it would be like swapping a 2.8/3.1 to a 3400/3500 engine in the second gens.




On the inside my car looks like a fighter jet.

its not... all the 2.4s have fly by wire throttles, fly by wire steering, and IIRC the reluctor wheel is different so the J-body PCM wouldn't know how to read the CKP (crank position sensor)

It has been done before. You need an external trigger wheel to run it on the stock ECU and you need to swap on either a L61 or LSJ head. Oldskool has done it to his 2 Js, Newt has done it to his sunfire, and Qwibby had a turbo on his swap.

I heard a guy claim to have aa complete 2.4 Turbo out of a colbalt in a 03-05 cavalier. Never saw it but he ssaid it runs.

Its a car, not a plane, Kyle. DRIVE by wire.

Oh and it is not "drive by wire" steering, it's electronically assisted steering, as opposed to J's that have hydraulically assisted steering.

That is interesting it is sounding more and more like a 3400 swap in a second gen since you need a crank sensor and stuff swapped over from an old engine. Why can't you use the 2.4 eco head?

fly drive... however you want to explain the signal transfer from the pedal to the throttle over a wire...

twas early this morning, so excuse the fly by wire remark for steering... Hyundai uses the same style electronic assistance, and Hyundai warranty pays less than a hour to swap the electric columns out... (I work for Hyundai (to make this relevant))

Because of the VVT. Our ECUs cannot support it.

Search for the "Freakotec" swap on here.
