in my quest for more n/a hp what would you guys recommend for a header for 00 miata. I've done research so far only on usdm products and found that the 4-1 racing beat is the best one to go with. any input on jdm parts that would fit my us application or any other usdm header that produces more power.

What kind of power are you looking for?

 

[sonique128]

Header, performance exhaust, timing bump, maybe even a test pipe is the best you can do to add more HP without going totally insane for the pocket book.

Oh and a recalibrated RX-7 NA (FC) mass air flow sensor.

FC MAF sensor only works on cars with 1990-93 ECUs. It is especially helpful for those who've swapped a 1.8L motor into their 1.6L car.

He has a 2000 miata, he doesn't have a flapper.

Also can't do a timing bump (easily) on an NB.

Swap in a FE3.

 

[nwdrifter]

opted for the rb 4-1 installed and ready go decent power thru out low and high. slight change in exhaust note. actually spent another 150 in misc stuff like wires, tape, exhaust wrap and custom o2 bung.
