The AMS Subaru STI Stage 1 EJ25 Short Block is the ultimate solution for
high horse power reliability. We use only the best off the shelf and
custom designed AMS spec components. Combine that with the latest in
machine and assembly practices and you are assured only the best!
All our race engines
are individually handcrafted at AMS using the same care as the ones found in
our world record holding street and race cars. When you choose an AMS
engine you are investing in the knowledge gained from assembling 1000's of race
engines over the past 10+ years. With over 200 Victories in Motorsports
over the last 3 years alone, it is clear that AMS is the only choice for your
car!
Just like our 1500
HP Alpha GT-R's and 1400 HP AMS Drag EVO, every motor is balanced, blueprinted
and assembled to AMS’ exacting standards. Before assembly each block is
checked for correct dimensions, cylinder bore, mains, block flatness, etc… to ensure
you get the best foundation for your new engine. Every engine we assemble has a
build sheet where tolerances, torque specs, and clearances are documented.
