the gtr pumps are fine (unless you plan on more then 250rwkw), and are a direct swap for your old gtst fuel pump. Unless you want to go a nismo item (which is roughly $600 from memory) you'd be hard pressed to find one that is direct fit around here. They are cheap, but by no means a 'crap fuel pump'. Walbros are another good pump which is well priced, and in a few group buys i've seen of them, the guy threw in an installation kit consisting of all the other bits and pieces that you need to get it installed (with instructions in some cases). Didn't seem like much modification was required.
