Referring to vq35hr:

How much power are the stock fuel injectors good for? (estimate) & at what point does the fuel rail have to be swapped for a bigger one? Thanks.

 

Stock injectors are good for stock power and boltons. Maximum power on stock fuel rails is not a set number. What are you trying to do?

 

Rails um when you go with a fuel return system. I have 540 whp twin turbo setup on my HR with 600cc injectors and stock rails. But I am going to be getting those out for a fuel return system.

 

Thanks guys, I just wanted to know for general knowledge. My goals are 450-500whp and was curious if stock injectors would supply enough fuel with just a fuel pump swap, I guess not. I suppose I'll be perfectly fine with stock fuel rails.

 

With upgraded injectors, the OEM fuel rails are actually very capable of flowing fuel past the 500whp mark. How much power are are you eventually looking to achieve?

The stock injectors are good for about 300whp.

 

Is this 450-500rwhp on a SC or a turbo setup? SC setup will require more fuel.

most likely single turbo, what size injectors should I be looking at?

 

if stock block, 600cc, if built, skies the limit

 

yup, stock block; keeping it under 500whp

 

find a single turbo kit for a hr let me know i want in

 

Boosted Performance?

 

Ugh for the ancient thread bump. Just go with Gamma Motors TT kit (if you do go thru Concept Z performance as the man in the middle - DO NOT go direct), or AAM. I figured I'd name drop Gamma for OG to get a chance to post a response

 

Go boosted performance it has everything you need.
