Well, ive been looking to upgrade the intake manifold on my gsr in my eg. THe manifold that is on it makes things tough when it comes to intake choices. So ive decided to buy a skunk2 piece. My buddy has one for an ls but i dunno if it would work. Is there any difference between the two?

 

they are two different part number for that skunk2 intake manifold and they are not compitable

 

If your Gs-R motor is relatively stock, I wouldn't rip the stock manifold off.

It is a very good manifold.

Regardless though, no a LS intake manifold will NOT fit on a Gs-R Head. The bolt pattern is different on the back of the head.
Although it MAY fit if you re-drilled the manifold, to fit the Gs-R head.

 

well from the looks of it you want to change an entire intake manifold so that you can put a INTAKE SYSTEM...? you want to spend a total of 200-300 dollars and an entire day of work, i can tell that you dont have much mechanical aptitude for asking such a question, to gain 3-4 horsepower...use your money wisely and invest in better tires, new brakes, tune-up(which would probably do more good)etc.
