Want to put a 1.8 engine in your 1990-93 Miata? Here are the parts you'll need.

Made in the USA

Exclusive to Flyin' Miata



1.8 swaps are becoming more and more popular and with good reason. It's a simple way to get more power. In the past, there was some fabrication involved. Not anymore - this kit includes everything you need for the swap. All the parts are available separately as well.

  •  EGR plate kit
  •  throttle cable bracket
  •  coil bracket
  •  motor mount brackets (optional)
  •  rubber motor mounts (optional)
  •  throttle body adaptor kit
  •  electrical parts needed to extend your CAS wiring

If you're using a stock intake or don't want to swap thermostat necks, the hose splice will make your life a lot easier.

 For more information on how to do a 1.8 conversion, please see the writeup in our technical section.

 Your 1.6 computer does not require EGR, so you can either leave the plumbing in place or remove it. If you do the latter, 1994-1997 and 2001-2005 exhaust manifolds will need an EGR cap while 1999-2000 exhaust manifolds will need an EGR plug.

The coil bracket is not compatible with VVT engines.

Excellent conversion kit!
This made my swap so incredibly simple. I had never done anything of this magnitude before and I had no trouble at all. This review doesn't allow me to add photos, but it looks completely OEM when installed. I'm about to help a friend complete the same conversion on his car, and this was the first thing I suggested he buy.

Legit parts.
I used this kit to put a '97 engine into my 1990 and it's going strong after a couple years of street, track and autocross. Definitely would buy again.

Worked like a dream
This kit was perfect for adapting a BP6D into an NA6. I didn't use some of the components but it was all perfectly machined and never had any dodgy modifications to make.
