I bought a SAFC2 and a Wideband for the 98GST. Now I am looking at injectors, precision turbo injectors at slowboyracing.com. I have a 190lph fuel pump. What would be the best injectors to tune with? 580's, 680's, or 780's. I don't think I'll ever need more than 350 horsepower.

 

i would think that 580's will be big enough

 

Thanks. I just thought I'd ask since its the same price for bigger injectors. Just out of curiosity, what are the biggest injectors that the 190lph will efficently supply?

 

How much Psi are you planning on running?

 

i would say 680... but thats just me

 

Im not exactly sure yet. In the neighborhood of 20 pounds. Im trying to decide what injectors I should go with, I was thinking maybe I should get some with room to grow just in case I want more power in the future. I've narrowed it down to 580's or 680's.They are the same price at slowboy racing, so I guess it makes sense to get the 680's.

 

could 680's max out the 190lph?

 

you wont max out either ever... because your only running a 16g

 

ahh okay. Good to know. Thank you.

 

560s are more than enough to get 350HP they are fine for more than that. I run 21 PSI daily on my stock 560s and stock 190pump in the EVO

The 190 people recommend upgrading on the EVOs at about 22PSI.

680s are fine but are a little over kill but for the same price as new 560s you might as well go with bigger ones incase you ever want more down the road its ready for it
