Alright, I know this is a turbo forum, but I also know there are SC guys roaming around here and there.

This header was created by one of the first individuals to produce a racing header for the miata. That header was affectionately known after the creator, "Boig" the header for the miata and was used in many dedicated road race Miatas. Later he worked with a header shop to design a supercharger header for the Miata that would support horsepower levels above 220whp where most of the current off the shelf headers can't flow enough to keep up, it became known as the "Gibb SC Header" after the man himself. I was running this header on a 270whp/216wtq supercharged 1.8L miata and this header was a big reason I was able to achieve those numbers. I am now parting out this project to work on my classic mustang, hate to let it go, I have over $1,000 invested in getting it to its current state.

Bump

 

Will this fit an 02?

 

He had it in a NA but was using a '99 head if that helps.

 

Yes it'll fit any 1.8L Miata. The only thing I'm not certain about is the angle of the flange on the CAT from a 94-97 vs 99-05. This would be a very minor change for an exhaust shop to do to make your CAT fit such a great header.

 

And although you call it a 'supercharger header', it probably won't fit with a hotside MP62, right?

 

It will fit a MP62 Hotside setup. If you look closely at the primaries you'll see they leave the head straight out. They don't curve upwards in anyway that would hit a MP62, no different from other headers in that aspect.
