i have a b16a swap in my eg.
is b18c and b16a headers are compatible? except maybe collector diameter differences.
does anyone of u run an aftermarket header but still can keep the ac system?
i was trying to install a megan header (4-1 one piece design) but the ac high pressure pipe is in the way so i cant get the header to bolt on..
please help.
thanks

 

i have a 4-1 on my b18c
no problems

i have no idea what a high pressure pipe is, i'm guessing its one of the two up front?

we need a picture, what part is blocking it?

what bracket did you use for your ac?

 

unfortunately i returned the megan header and it is one of the ac pipe that goes from condensor to compressor. the thinner one..
i am using a p30 ac bracket with a 95 gsr ac compressor
