Hondas blocks and heads are interchangable hence why you can take a D15 block and throw a D16a head on it, or take a b18 and throw a V-tec head on it. In theory cant you take a 2.2 and throw a 2.4 VVT head on it? Would you need a 2.4 PCM? Would it even run?

 

idk. good question. it wood be sweet if u could.

 

i am sure it would physicaly fit.. but tuning it and getting it to run would be near impossible i think

 

Why not wait til the le8 comes out???

The problem would be sensors...it would be a headache

 

Lemmy know how it turns out.

 

Shiot, I dont have the money to test this theory, I barely have the money for the front bumper I need to replace.

 

well theres ur problem

 

^ haha

 

You would need the 2.4 PCM, as the 2.2 PCM lacks the VVT controlling capabilities.

 

even with the 2.4 pcm the car probly wouldn't run. like said earlier you would have problems with sensors and such

 

if you swapped the harness, ecm, and changed the head i think it would work but you may need to change the insturment cluster too, and you might still need to program the ecm to the bcm i don't know how these cars are set up. i'm pretty sure that the block are from the same cast so all the sensor in it should be the same.

 

its not that simple in hondas either..u dont just swap heads and call it good..but they have had the experiance in doing it and no one in the cobalt comunity goes that route

 

it's easier to change the block than everything else.

for example, i helped install a 7a-fe bock into an MR2 that had a 4a-ge originally.

that gave us a 1.8 litre rather than a 1.6.

sooo, if you had a 2.4 and wanted a 2.2 block, i guess you could... but why?

conversely, you MAY be able to put the 2.4 block under the 2.2 head and gain some power, but the tuning isn't there.

 

My buddy is a Honda Guru and we were talking about his k20 block/k24 head 6 speed CRX which got me thinking about that.

 

u mean k20 head and k24 block..??

 

Sure, I dont know **** bout Hondas. I know it was some combo like that. I remember K20 and K24 were mentioned to be in it and one came from a RSX...

 

lol i wasnt calling u out...but for the most part people go with the bigger block..

 

No problem man, I dont have a big e-dick, I can admit to being jack of all trades, master of nothing.

 

lol i hear ya..im a jack of about 7 trades..and still havent mastered any

 

yeah, i know just enough to F-ck something up. LMAO

 

i'm sure it can be done, Hondas have alot more backing from shops and stuff though so they can afford to have someone try it...

2.2VVT, yeah!

 

Next year it'll be a standard build, presumably the Cobalt will get it. http://www.theautochannel.com/news/2...06/076896.html

 

Great now the question is if there will be a Hondata-esque pcm for Chevy...

 

switch the head, the ecm, the harness, and the instrument cluster? it might actually work if you do all of that.. who knows, somebody needs to try!

 

There is a guy I know of with a LSJ head on the 2.4 block... call it a LSJ stroker...
