On another forum, there was talk about swapping a 2.4 crank into a 2.2. One person said it would make the 2.2 into a 2.4. I know you would need a tune, but what else would you need to swap to make this work?

 

so noone has any kind of input on this?

 

i dont know any info on this buddy, sorry

 

The two cranks have different triggers for the sensors. If you search i belive there is a thread about this, a guy with a sc2.0 did it.was alot of work if i remember right.

 

I believe you would need different pistons and rods also.

 

its too much work...

easier to just put in a 2.4 motor and change the ecm

 

Why try to half ass a motor together when you can just build a 2.2 correctly?

Sure it is, have you done it? I think not.

 

uh oh.

 

mmmm......nothing wrong with building an engine using parts from different variants.

K24/20 series frankenstein,
B18/16 series frankenstein

those are just a couple of the variants of honda engines variants which used in the correct combo results in some good power.

same kinda thing amongst many brands, it's just unheard of in ecotecs.

what ya should do is examine the books for the le5 and l61. if yur gonna do the crank, do the rods and pistons too. then you'd pretty much have a le5 performance-wise, just wouldn't have the variable timing chevy vtecness hahaha though.

not too much work, just gotta probably do your research a bit.

 

^^^true

 

Please dont ever compaire a honda to a ecotec, why do all that work when you can do it rite the first time with "real" forged internals, just sayin.

 

I'm completely new to the building an engine thing... I just trying to grab some ideas and see what will work and what would need to be done. The other thing I was wondering is it possible to use a 2.4 ECU with a 2.2? I know this is performance. Maybe I'll look around the tuning section for a bit.

 

No its not possible.

 

hes right, but you can have your 2.2 tuned pretty darn nice with supporting mods, but boots or spray is the best power for money...

 

Build it as a 2.2L. GM had a monster build on a 2.2L Block.

 

They got money on the mind, this aint happening if you do that. It will cost 7k+ to do it correctly.

 

I will be working on putting an L61 head on an LE5 bottom end in my cavalier shortly (which is a bit trickier than the cobalt), but here's the story.

If you have a 2007 or newer L61, the crank triggers should be the same (60-2), so you simplly bolt on an L61 head and run the L61 PCM, with a retune of course. Otherwise you need an external crank trigger bolted and timed properly to your crank pulley You will get a nice bump in compression as the LE5 is already 10.4:1 and you have a smaller chamber volume with the L61 head. I've also heard that your better off getting an LE5 bottom end w/o the oil cooler option to make life easier.

I've heard of one instance of this hybrid done in a fiero swap, and the owner reported that the car needs bumpier cams because there is a lack of high rpm power using a stock L61 head/cam combo. FWIW, I think he was maybe a little disappointed and thought he would have a beast right off the bat.

The big benefit of this swap (for me) is having the LE5 bottom end that's been proven to about 400hp.

Why is everyone making it sound so difficult?

 

Because 99.999% will never want to put that much effort into somthing. Good luck though man.

 

word. there's some ingenuity
