After being a Infiniti person before a 300zx I worked on the Q45s and a moderator for Infinitihelp.com.After getting involved with the 300zx and fuel pressure flow etc, I found out that the Q45 pump was the same as the TT...I use one in my TT now...with the correct fuel flow. I actually can get the Infiniti pump cheaper than a TT pump from Nissan..
