We`ve been using silicone water lines on our turbo kits for years. They do a good job, but they do require periodic replacement - especially on racers. This hard line kit replaces the flexible hoses with custom-bent stainless steel lines, similar to those used for your fuel and brake lines.

They fit any 1.8 FM turbo that uses a Garrett turbo, including the GT2554, GT2560 and GT3071, with the exception of the 1999-2000 two catalytic converter model. If you have a Mazdaspeed with the FM II conversion, some of the factory fittings will need to be plugged off. There may be interference issues on older kits with steel tubes that cross diagonally in front of the engine.

These hard lines won't work with the FM reroute, please use the FM reroute-specific silicone water line kit if you have the FM reroute. 

Available as an upgrade to any new 1.8 FM turbo.

Please note that banjo bolts are not included with this kit but are available separately. If your turbo is already equipped with our flexible water lines, the bolts can be reused.

Customer Reviews

Based on 3 reviews

Honestly I’ve never had a bad purchase from this company and everything gets to me so fast that I honestly would recommend them to anyone looking for Miata parts

These lasted about 6 months

I had the same failure as the other reviewer, while these install nice and fit perfectly, the seal between the fitting and the tube looked poorly brazed and did not seal. It lasted about 6 months on the car, with only 4 track days.

Note from FM: We're really sorry about this failure - we had a few issues, but our supplier has since instituted new QC measures to address this issue. Please reach out to us and we'll set you up with replacements.


Let me clarify the rating: 1 star for the product, 5 stars for the customer service=3 stars. I ordered the upgraded hard lines with my turbo kit. The outboard line has been fine. Both the first and the replacement lines sprung leaks at the solder joint with the banjo fitting. The tube is aluminum I think (not magnetic) and the fitting is some kind of steel (magenetic). Not sure if it was brazed or just plain soldered but they need to figure out a better way to connect the two. My solution was to completely remove the fitting, sand off all the solder, then bond with JB Weld. So far so good, but I assume it will fail at some point with all that heat. Many thanks to Eric Anderson for sending me replacements. The second replacement line is sitting in my garage waiting to be installed when the JB Weld fails. Hopefully that will remain water tight.
