Update - Parts are starting to roll in from Jap... first to come is the Nismo pump, great unit, bigger than walbro and bosch that I have seen but i'm not sure if they flow more or what not, but it's definately quieter than walbro/bosch equivalent, although more expensive, i feel that it's worth it
It doesn't come with just the pump but a couple of little bits and bobs
Comparing the stock pump and nismo pump
First impression, car felt alot smoother (I'm not sure it's due to the $$ I've spent) but car felt more power as well
