I have searched the forums and I have gotten various yes and no answers , so my question is does anyone know if the header manifold setup on the 2jzge engine from all years of the sc, gs, and is are the same. For example lets say could a 94 2jzge sc300, a 99 gs300, and a 2002 is300 use the same set of headers?

I would assume yes , I know that the bottom end might not bolt up to the stock pipe setup but that is unimportant because i am redoing all of the plumbing, but i need to know if the headers will bolt to the engine. I know about the XERD headers but they are hard to get a hold of and there are an excess of options as far as headers go for the is300.

 

i think where it mates up to the head is the same....but where the stock piping is...no.

 

from what i researched and heard about from xerd is that the is300 headers will bolt right up, but the bottom end neds to modified to fit stock exhuast....

Someone correct me if im wrong.

 

Top..Yes!
Bottom.No!

 

You can tecnically fit them fine, you just need to slightly modify the piping in order to get them to fit. Otherwise the flanges will bolt up just like any other 2jz (non-tt).

 

thanks guys thas the answer i was hoping for cause I ordered is300 headers like 5 mins after i made the original post, cause i needed them asap, so i'll post up pictures when i get them on for other members , plus they are only costin me a few hundred as oppsed to the 400 for the xerd ones.
