has anyone ever heard of this being done? i found a 2.0 head for $350 and figured since i might have messed up my head from my turbo i might go wit a 2.0 head. will this work? if so wat differences have been made?

 

iirc it will physically fit and bolt up but the cams have different timing to them. anyone else wanna correct me or add to that?

 

the cams arent usable even if everything is tuned?

 

I'm goin with what yellow said.

Cams could be used if you get it retuned after the install I suppose.

 

Why don't you just port and polish your 2.2 head and buy stronger valve springs and cams. You would require a new tune because i believe the 2.0 cams have a slightly different grind to them than ours

 

well im still dialing in on my tune from my turbo so i figured if i get the 2.0 head then i can just have vince add that tune on as well

 

GM build book used the LSJ casting on a 2.2 block, as it is a better designed head from the get go.

The LSJ head uses different cam castings, but the grinds are the same. I believe you could use the 2.0 head without any actual modifications, the 2.2 doesn't have the cam sensor, so the LSJ sensor won't be an issue, just leave it unplugged.

 

well im not sure that the cams can be used but dont hold me to that since anythin is possible. they have the same grind as the 2.2 its just timed different is what i've always heard. so basically you might would need adjustable timing gears to actually make up for the difference in the timing.

 

sweet. wat are the positives/negatives from doin the swap?

 

this is something for maven :p

 

ok i wasn't sure if they had the same grind pattern to them. If i was you i'd buy some turbo grid cams and stronger valve springs, would be nice but then your bottom end would need some stronger parts.

What exactly is wrong with your head right now?

 

positive would most likely be the fact that the timing on the lsj cams are for F/I so that should be a plus. down side would be if you couldnt use the cams.. lol

 

well i just wanna get my car back up and goin. when i get back in september ill worry about that, but i need my car up until may...bumming rides suck

 

you sir are right. lol

 

yea, maven does need to pop up now to shed some light.

i couldnt use my 2.2 cams on the head?

 

thats somethin that i dont know bout the 2.2 cams in the lsj head.

 

hmm aight. i think ima PM maven and see wat he says. i really appreciate the help, hopefully the item is still for sale come friday aka payday

 

wheres maven at?

 

Use either cams, as long as you time them for the 2.2, the timing will be the same. The 2.2 blanks fit in the LSJ head physically, but they don't have the cam sensor, so the LSJ guys can't use them. In your case, pop your 2.2 cams in, block off the cam position sensor, and you will be fine.

 

not online

got ya

wat are the blanks?

 

they are just a solid cam shaft that hasnt had a grind on it yet. you get them custom ground the way you want them

 

hey joe, just so u know.. '07+ 2.2's have the cam sensor...i dont know if its the same sensor as the one on the LSJ or not though...but they definitely have one.

 

i'd reccomend a turbo grind cam. if you do a little research on the subject you'll find that the sc and turbo grinds are different when it comes to timing of course it'll work but i found that the sc grind is similar to na grinds and turbo grinds are modified to flow differently when it comes to the int. and exh. vavle timings cause they don't require exh scavaging. if you do go with the sc grind get a bov if you don't already have one.

 

i got a bov already. does the head off a 05/06 SS/SC have a sensor? my cobalt is an 06

 

Yes it does have a sensor. If you just look at the cam gears they MAY have marking for 2.2 timing on them. Never looked so i'm not sure, but you could probly just bolt your cam gears from the 2.2 head to them cams in a 2.0 and be fine
