Multiple php (php-fpm) version on LNMP server

Question

One of the projects requires support much higher version php used in main web project

Env:
- Debian 7.6 (3.2 x86_64)
- Nginx 1.6.0
- php-fpm (PHP 5.3.28)

My task: Install alternate version of php-fpm (php) and use it in another web project.
I don't want to install Apache with the desired version of php (mod-php) and use Nginx as frontend for Apache

Please describe other ways of resolving my situation, if they exist
