I just got a 1990 ef hatchback with a jdm dohc zc and a l3 lsd tranny. Car is pretty straight not to much rust. Will probably end up making a build thread soon but I am looking for a header. I know this topic has been touched numerous times I have done some reading as well but I keep getting different answers. What headers will work? I found a spec d header that said it will fit a d16. would that work or will i still need to get the ports grinded? I emailed bisimoto and I am still waiting on a response. is that my only option? Pics below are of my new ride! and first thing that happend was all the stickers had to come off.

 

or what headers do you guys recommend? I do plan on running low boost on it eventually.

 

The flange is the same, the ports are shifted. It will fit as is, the grinding of the ports have nothing to do with fitment.

If your plan is to run a turbo you are waisting money on an aftermarket header.
