Right now I'm in the middle of rebuilding my 87 T2. While my car is all torn apart I'm doing some mods as well, but I need a little conformation on my fuel setup.



First here's the mods I'm doing:

streetport

Stage 3 turbo upgrade (t04 with 60-1 compresser wheel)

catback

cone intake



Here's my fuel setup:

S-AFC

FCD

Walbro Pump

and 4 720 injectors



Does this sound like plenty enough fuel for my mods? Am I forgetting anything?



Thanks, Ed

I can get bosch injectors for $95 each or nippon denso for $110 each.

Which should I go for?



Thanks, Ed

thats plenty of fuel, i ran the same setup with the stock injectors and i could make the car stumble it was so rich. where are you find the nd injectors? i would go with those (stock) over the bosch

You should also add a fuel pressure regulator. But thats if you go the cash for an lines an rails.

you can also plug the stock regulator into the manifold, it becomes rising rate when you do that

it does? cool. Where is it normally plugged into?

its plugged into a solenoid. When you plug it directly into the manifold it increases the static pressure and it becomes a rising rate regulator.

so that means it rises 1 psi per each pound of boost, right? is that how those work? it seems those would be hard to control, i don;t really understand the point of rrfpr.

yup, it does 1:1. think of it this way. the injector is pressureized at the fuel rail, say 43psi, and when there is 15psi vacuum (idling) on the other side, it flows x amount of fuel. what happens when the fuel rail pressure is 43psi and your boost is 15psi, the idfference between the 2 is less, so its gonna flow less fuel through the injector. the rising rate regulator is supposed to keep the raitio the same, ie at 10psi it raises the fuel pressure 10psi to compensate
