Default Side feed to top feed fuel rail conversion

Alright so im looking at converting an 05 sti of my friends from side to top feed so we can run 1100cc injectors without all the extra junk like resistor boxes.

Im thinking all we would need is 07 sti tumbler valves, top feed rails, and injectors.

I just want to make sure its that easy and it doesn't require anything im forgetting or more work then i think.

Yep. You'll need a fuel pressure regulator as well since the side feed and top feed ones are different. If you're interested in any parts to convert to top feed, hit me up.
