2.2 header and lsj header
what is the difference between our stock 2.2 header and the 2.0 lsj header
|
the lsj will bolt up and add horses and torque, the lsj is bigger, there are threads on this look them up
|
^^^ 07+ 2.2 manifolds are the same size. the lsj manifold just has a provision for the o2 sensor in it.
|
Sorry, but the information here is incorrect. I know because I have the LSJ header and LSJ DP on my car. The stock 2.2 header is much smaller, and does not allow as much flow. The 2.2 header is longer and the 2.2 DP is shorter. The LSJ header is shorter, but the DP is longer. So, if you want to use LSJ DP or header, you must use both or it will not fit. But trust me when I tell you, the header is certainly smaller on the stock 2.2.
|
i have a lsj header for sale
|
by looking at both of them side/side they are almost identical besides the o2 sensor hole in the lsj
|
If you are looking for a little more bang for your buck outta that LSJ manifold, have it ported. I can do it, did a bunch of them back in the day, gain a couple hp and still look stock.
|
And FYI stock is an exhaust manifold not a header!!! Header's are tubular.

thats not correct either,that was a Auto to manual comparison lol,all the manifold on the outside are the same,its the runners and collector thats different i also have a lsj mani with slight polishing for sale as well,there the same ive had both side by side
|
not trying to discredit you gene but you also had sai. i dont the manifolds and the downpipes are the same length.

i dont. but i do disagree with you on this. i have both here in my house let me check again. but i remember looking at the downpipe and them being the same. and im pretty sure i have NEVER discredited you on anything before. and never said you were an idiot. the only other thing i have said to you was asking you about how much hp you had and what all you used in your build when you first got it done. anyway back on topic let me check them.
|
The proof is in the pudding. This is what the difference looked like for me. PS. Also notice LSJ DP is slightly longer, as I stated.

lay one on top of the other. the downpipe very well could be longer. i will stick my foot in my mouth now.
reason it could be longer is the motor sits different in the ss than the ls/lt. my ss/tc downpipe sits about 1/2-3/4 of an inch off my swaybar. (partly due to the way the catback fits in the base model top of flange to top of flange on each end seems to be almost identical. |

now line those up in the other order, lsj closer to the cam and the 2.2 farther away from the cam, they are the same length, its like an optical illusion...how much longer do u think the lsj dp is than the 2.2? have you taken a measuring tape to them?
|
anyone auto put the lsj h/dp on their cars?
i wanna make sure this'll fit |
wont fit the auto. manifold will, dp wont. they are different in the sense the auto sits in a different position than the standard.
|
fml right.. where can i get a 2.5in dp. every place ive seen is 3in !!
|
zzp.
