4B11 Shortblock
AMS EVO X Stage 3 2.2 Big Bore shortblock with Sleeving 9.5:1 Compression (no core required).
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.
