Hey I couldn't find this. and I didnt know where I should post it. I have a 2.2L but want to make it a 2.4L. what do I need??

pistons, rods, and crank?? and bored cylinders

 

won't you also need the 2.4 intake?

 

Are you just looking to increase displacement?

 

to match the 2.4 completely, you'd need the whole head with VVT as well. im not sure the e16 has capabilities to run VVT, and if it does, it's not cracked yet anyway, so you'd need a standalone system

 

sell it and buy a 2.4...

 

don't say that you sound like SOME ss/sc owners. Its most likely not worth the gains. I'd look at another way, more cost efficent way, to make hp.

 

its really not. the price to swap heads, finding a source of tuning that can run VVT, stroking the engine, and getting new higher compression pistons will be pretty damn pricey for only a 25hp increase.

 

ok, I am replacing the engine internals anyway. I am not looking to do it for a small HP increase. I am doing it to try to get 300hp NA along with a lot of other mods. BUT I have found that it will be too hard with everything that goes with it. Thanks for you help guys. I am just going to have to slap a turbo on it.

 

if you just increase displacement to 2.4l approximately, and build your head accordingly...i bet you could be near the 200hp mark.

 

The 2.2 and 2.4 pistons are the same size -- stroke of the 2.4 is longer -- different crank. Not sure you could put a 2.4 crank in a 2.2 block.

 

Turbo

 

Increasing displacement is perhaps the most-proven technique to improve horsepower and torque, and that?s where GM Powertrain engineers started when developing the Ecotec 2.4-liter. For the new 2.4-liter variant, both cylinder bore and stroke are increased in relation to the original Ecotec 2.2-liter engine. The new engine's bore is 88 mm and stroke is 98 mm, versus the 2.2-liter's 86-mm bore and 94.6-mm stroke. These increases, multiplied by each of the Ecotec 2.4-liter?s four cylinders, yield a total displacement of 2,384 cubic centimeters versus the original 2.2-liter's 2,189 cubic centimeters

 

I sit corrected...

 

to get the displacement itself you just need to throw a 2.2 head on a 2.4 block

assuming it'd work u'd have a 2.4 but without the issues of a straight swap

 

The LE5 block is different.

Seriously...swap the motors out...it would be the easiest.

OR

Bore a litte with bigger pistons...you more than likely are NOT going to be able to make 300hp without some sort of F/I

There is a guy on ecotecforum who has a 2.2 cavi at 14.0 in the 1/4 N/A

If you are going to bore it out I would suggest getting a patriot head at the same time...but the LE5 and L61 have almost NO interchangeable parts

 

blah, everyone is a hater. heres my rough guess of how much it would cost...

overbore l61: $100
used 2.4L crank: $300
used 2.4L intake: $100
custom pistons: $600 (the higher for NA the better)
custom rods: $500
misc gaskets: $200
misc bolts: $200
------------------------------
total: ~$2,000

and thats before buying a clutch/flywheel or any additional machine work. and if your crank isnt the same diameter as the 2.4L you can machine out the block and griddle to fit (maybe another 150 bucks + new 2.4L bearings).

even if you didnt make much hp per dollar, it would be a good starting point for some serious boost. For 2500 bucks, thats worth it.

for additional ideas, look at MVP/fullthrottle's build of a LE5 with a LSJ head/tranny/m62.
