Yes, I made sure the A/C would remain in place and function perfectly, my old fun car did not have AC and it sucked bad in the summers lol. As far as the gearing goes, the 07/Spec B gear set gives nicely spaced gears and they are a bit longer which is nice when going to the dragstrip. The Spec B 5/6 are longer than the STi gears which is nice when cruising on the highway too.

I have a modded stock hanger with a Walbro 450 lph pump and a Walbro 525 lph pump (mixed up just because that's what I had on hand at the time). The outlet is a -8AN on the stock hanger which is connected to a -8AN line ran all the way to the engine bay. Then I have an ID F750 fuel filter, going to a Radium Fuel Pulse Damper, then split -6AN to each fuel rail.

Return side is a -6AN from each rail to a Radium Multi Fuel Pressure Regulator, then I have 2 -6AN outlets, one going to each OEM hard-line (tank to Bay). By using both OEM hard pipes as the returns it has plenty of flow to keep fuel pressure under control even with both fuel pumps running at 100% all the time.

I have come up with some ideas for fuel system improvement if I decide to chase more power, but that would be after summer at the earliest. I want to run the car as is since it's a great time right now.

I'd upgrade the intake manifold too if I do decide to add more fuel.
