I've got a header fitment issue. I have a 91 CRX with a 96 B18B1 using HASport billet mounts. The placement of the motor is really close to the radiator. I built the car and gave it to my fiance and she wants to put the A/C back in using the HASport mount. With the fan in, the LS exhaust manifold is really close to the fan - I would say only about 1/2" away. I wanted to go with a DC Sports 4-1 stainless steel header but I'm not sure if it will clear the fan. I was just wondering if anyone has a similar setup and which header you are using.

 

I don't believe the DC 4-1 comes out any further than the factory b18b1 header....i could be wrong.

But from what I have seen in my friend's with headers, it's about the same clearance.
