would a usdm itr header and intake manifold bolt right up to a ls and gsr motor ?

or is there other stuff i got to get so it would bolt up

 

header, yes

IM, no

you might need some custom exhaust for the header, depending on the chassis you put it in

 

it will bolt up to the block, but the lenght of the collectors is different. I believe (but i could be wrong) the the LS and ITR are the same length, but the GSR is shorter. All this means is you will have a gap between the car and the header. Not sure if just bolting up a GSR cat will fix this either.

 

well the thing is my buddy got a gsr shell for cheap and just to drive around with right now he got a ls motor dropped in, but the exhuast from header back is going, so im just trying to help him out, and i have a gsr with jdm gsr so i was just wondering for myself if it would bolt right up and have no problems

 

neone?

 

need some help here
