as title states. Im putting my B16 head on a GSR block, can I use my same B16 header?

 

i have the same setup. i had no problems with the fitment so yeah i would assume you should have no problems either

 

Yes

 

Ok thanx, I just wanted to make sure the deck height with the bigger displacement wouldnt cause any height issues

 

Actually, sometimes it does. it will fit perfect on the head but the header might be too short and hit the block. if you have an after market header, then maybe they will work because a lot of after market headers are long as hell anyways.

 

All B-series headers will interchange. The only difference is the downpipe length and bolt configuration. For example, if someone wants to swap a LS into a EG hatch, he/she must use a B16 header in order to bolt up to the existing exhaust piping.

 

It might hit the oil pan.

 

this is not true i have a stock ls swap in my eg using stock ls header with no problems so i dont know what the hell your talking about

 

Did you have a custom/cat-back system after the swap install? It will not bolt up to the stock catalytic converter if you use a B18 motor.

 

The LS and b16 are the same length under the oil pan. GSR headers are several inches shorter and will not reach the stock cat. A pipe can be fabbed and bolted or welded in for less than $40. Also, if going with a gsr, an L header's bracket will hit the oil pan. It needs to be grinded off.

edit: oh yeah, to the op, of course you can use the same header. The b16 and b18c1 heads are from the same cast. They are the same dimensions.
