Advanced Tuning Products (ATP Turbo) is a company that has devoted itself to turbocharging and all that is associated with turbocharging. They have dedicated their engineering and manufacturing towards taking fresh and functional approaches with re-imagining turbocharger systems. Their designs are simple yet highly effective and reliable. ATP Turbo is centered around adapting Garrett Turbocharges to many different vehicle types for easy bolt on installation with all the performance that is associated with Garrett turbos.

At EdgeAutosport, we carry the complete line of ATP products but today I just want to feature the bolt on turbo kits. Aside from the AP and Autotechs, this is the next best bang for your buck mod available to the Mazdaspeed platform. And bolting on 350 to 400 horsepower doesn't get any easier than this.

To start, we have the ATP GT2871r Bolt on Turbo ($1499). This turbo is efficient from 20 to 21psi on the MS3 and 6 and will flow enough air for up to 400 hp at the crank.



The next step up from that would be the ATP GT3071 Bolt on Turbo ($1599). The GT3071 flows a bit more on the top end than the GT2871 but it does sacrifice a little more low end power with a bit slower spool. It can support up to 450 crank hp and is efficient up to 22psi on the MS3/6.



The ATP GTX2867 Bolt on Turbo ($1699) is probably the best all around turbo for the MS3/6 because it spools up like the GT2871 while flowing up top like a GT3071. This means it has a much more useable power-band that works within the range of the factory fuel limitations. The GTX2867 can support up to 480 crank hp.



All of the ATP bolt on turbos come with pretty much everything you need for installation. Including the Oil Return Line, the Coolant Feed Line, Low profile Banjo Bolt for the oil feed line, a boost tap to create a boost source for the BCS, and a coupler to connect the turbo to a top mount intercooler.
