Product Description
AMS Mitsubishi Ralliart 2.2L Big-Bore Short Block
For those of you looking for a big-bore version of the 4B11 engine,
look no further! AMS now offers the same 2.2L short block that powered
the record-setting AMS Time Attack EVO X (TA-X) to the 2009 Redline Time
Attack Championship! During the 2009 season, we were able to extract
850 horse power from this race-proven power plant – setting the world
horsepower record for the EVO X in the process! After testing this
amazing power house for an entire year of racing it is finally available
to the public.
Our 2.2 liter Big-Bore block adds displacement but in doing so
maintains a great peak RPM capability by increasing bore and not stroke.
With proper tuning and supporting modifications the AMS 2.2L short
block is capable to rev up to over 10,000 RPM!
This race proven power plant uses 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!
Each block is precisely machined to accept AMS’ proprietary ductile
iron sleeves. The sleeves are pressed into the block to sit atop a
machined step to ensure they will not sink during engine operation. The
new sleeves are machined to sit a few thousands above the rest of the
deck surface allowing for a tighter sealing surface between the block
and cylinder head. The block is then final bored, honed and align honed
with ARP main studs installed to ensure perfect clearances and fitment.
The finished product allows for higher cylinder pressures and added
strength and rigidity to the block.
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.
