I'm thinking of running a greddy turbo kit in my car, what kinda of fuel setup would get me to 350-400hp range. I was thinking of running new 550 all around and then adding a set of additional 720's

 

400whp with 550/720...not enough fuel.

 

What type of Fuel Management System will you be running?

 

the setup is a chipped ecu, and the emanage, with 550 primaries and secondarys plus additional 720's

 

6 injectors is a different story

 

if your looking at the td06 kit, they offer two now over here. The smaller is a 20g and the larger is a 25g. Should be enough fuel. Appearently you would be hard pressed to make that power with either of them on a stock port engine. You can also order a GReddy td07 25g from Japan....
