ulimit is a shell builtin on some OSes and in that case - you can't use shell builtins via sudo as far as I know.
If it is an option for you, you might want to change your limits permanent for some user via editing /etc/security/limits.conf or whatever file it is on your OS. Don't forget to relog to make changes for that user/shell active.

ULIMIT(3)						   BSD Library Functions Manual 						 ULIMIT(3)

NAME
ulimit -- get and set process limits LIBRARY
Standard C Library (libc, -lc) SYNOPSIS
#include <ulimit.h> long ulimit(int cmd, ...); DESCRIPTION
The ulimit() function will get and set process limits. Currently, this is limited to the maximum file size. The cmd argument is one of the following: UL_GETFSIZE will return the maximum file size of the current process, in units of 512-byte blocks. UL_SETFSIZE will attempt to set the maximum file size of the current process and its children, using the second argument (expressed as a long). RETURN VALUES
Upon successful completion, ulimit() returns the value requested; otherwise, the value -1 is returned and the global variable errno is set to indicate the error. ERRORS
The ulimit() function will fail if: [EINVAL] The command specified was invalid. [EPERM] The limit specified to ulimit() would have raised the maximum limit value, and the caller is not the super-user. SEE ALSO
getrlimit(2) STANDARDS
The ulimit() function conforms to IEEE Std 1003.1-2001 (``POSIX.1''). HISTORY
The ulimit() function first appeared in FreeBSD 5.0. BUGS
The ulimit() function provides limited precision for setting and retrieving process limits. If there is a need for greater precision than the type long provides, the getrlimit(2) and setrlimit(2) functions should be considered. BSD
