## Going from Good to Better:

When Mazda created the The 2004-05 Mazdaspeed Miata (MSM) they did us all a huge favor.  Factory turbo, aggressive styling, the stiffest chassis of any NA or NB - it's an awesome car!  Fortunately, they also left a LOT of meat on the bone when it comes to upgrade potential and FM has put together various packages that can turn it into an epic car!  You can start out simple with an intake kit or an upgraded downpipe, for example, and from there we have options ranging from bolt-ons to bolster the stock turbo system from the original ~155 whp up to around 200 whp, to upgraded turbochargers capable of making 250+ whp reliably on a healthy stock engine, all the way to "OMG" power with forged internals.  In fact, one of the biggest HP turbo build we ever did at FM was based on a MSM donor.

The chassis, suspension, and brakes are upgradeable in the same fashion as any other run-of-the-mill 2003-05 Miata so let's focus on what makes the MSM special: Boost!  We have lots of various power upgrade options for the MSM platform and we've put together an upgrade path specifically for these cars with the priority for ease-of-installation and bang-for-your-buck:

## Even More Betterer:  

If you're shooting for 300 whp or above, then you'll want to skip over the lists mentioned above and start planning your engine build.  The MSM is pretty well set up for boosted power but the connecting rods and pistons will still be the weak link in making reliable horsepower above the 300 whp mark.  Plus, there's no way the stock turbocharger can make that kind of power, so you'll be replacing your turbocharger and many other components in your engine bay to suit these power goals.  Start by picking out some reliable forged pistons and connecting rods for strength, upgraded valve springs for increased cylinder pressures and/or higher RPMs, a much more capable crank damper, and a high-pressure oil pump for starters.  This subject can start to get a bit wordy, so if you need help picking out the right parts for your build, give us a call and we'll help you select the best parts for your horsepower goals.
