So, there are MANY options out there for fueling upgrades for the Evolution X. There are a lot of opinions out there concerning what you should or should not buy. I want to condense all of that knowledge and personal experience into one thread.

Fuel Pump Options:
1). K27 In-Line 255 Walboro Kit
2). Blaq-Ops Walboro 255 install kit
3). MAP/UR Walboro 255 install kit
4). BR Double Pumper with 2 Walboro 255 pumps
5). Boomba Racing 255/340 Walboro install kits
6). DW56c drop-in pump
7). other

Injector Options:
1). DW1000, DW1300, etc.
2). ID1000, ID2000
3). MAP 1000cc, MAP 2000cc
4). FIC 1100, FIC 1600, etc.
5). RC Engineering
6). HKS complete fuel rail and injectors
7). other

Fuel Rail:
1). AMS Fuel Rail
2). Boomba Racing fuel rail
3). Arashi Turbo fuel rail
4). Cosworth fuel rail
5). other

Modification: Removal of Return Filter and/or drilling out return ports.

Which of the following options have you tried? Which have worked well? Which have been bad experiences? Which would you recommend to others to try?

I have experience with the MAP 255 install kit and ID1000 injectors on this platform. Both worked fine, yet the return pressure spiking was an issue (as it can be with pump gas). I just want to get some feedback from other members on what they would recommend. Thanks.
