‘08 Legacy 2.5i turbo build
I know a lot of these posts come around, but never follow through. But I will follow through with this for sure. I've got my parts list complete, and have begun ordering bits & pieces.
Background: I've had the car for several years and have had the itch for a new car lately. I can't justify it, mine has been paid off and there's nothing wrong with it. So instead of spending 20k+ on a new(er) car, I'm going to spend less than $2500 and make this one a lot more fun and "new" to me again. Car: 2008 Subaru Legacy 2.5i 4EAT 86k miles Mods: -H&R springs w/ Koni struts -Damn near every suspension bushing is Whiteline/Energy -Whiteline rear sway bar -LGT brakes w/ DBA rotors -Delta 1000 cams -Grimmspeed LW crank pulley -Grimmspeed phenolic intake spacers -AEM dry-flow filter -hybrid intake system -WRX injectors -e85 fuel -Infernofab 4-2-1 header -Infernofab high-flow cat -stock GT midpipe -HKS Silent Hi-Power axleback Turbo build list in next post --->

I'd like to say I'm doing this the "right" way. But I suppose there isn't a perfect way to do it, aside from either swapping a factory turbo motor in or selling the car and buying a factory turbo car. (I'm sure I'll hear that a million times during this)
I'm not buying the AVO kit, I'm not cutting my crossmember or making a funky up pipe. I'm going to use as many stock turbo parts I can to make this appear like it came from the factory. I feel that is the right way to do it. I won't type out the entire parts list, there's too many small things that most of you won't care about. But here's the main pieces: -Kinugawa TD04HL-20T -OEM turbo header/UP -CNT catless downpipe -LGT airbox lid/MAF -OEM turbo inlet -OEM BPV -Water to air intercooler -LGT front crossmember -OEM turbo swaybar I will have more parts and much more detail in future posts as I begin work. |

My friend has talked me into creating a youtube channel to document the progress of this build. This is my daily driver, so I will be doing a little at a time on weekends.
I will edit this post with videos as they become available. Channel: tipsymechanics First video is up!! Our camera had some focus issues, we'll figure it out by the next video. Part 1.5 is up! Part 2 is up! Last edited by tipsymechanic; 09-14-2019 at 08:55 PM. |

Hell yea do the youtube channel!
How are you going to tune it? I'd almost not bother with the 1000 cams, go straight for the 1500s or nothing at all. Especially if turbo'ing. EDIT: Whoops, didnt realise you already had the cams installed. How have you found them? Noisy? Make much difference? |

As for tuning.. I had my ecu defined by the folks on the romraider forums many years ago. I’m doing a lot of research and will slowly tune this setup myself. |

what's your plan for fuel setup?
I read that returnless fuel setups on the newer vehicles are PITA to tune so I was planning to swap an STI or equivalent tank and matching upgraded fuel pump and route a return that way. disregard if your vehicle has a fuel return still. |

I've got a Deatschwerks 65c pump with WRX 565 injectors (they flow tested @ 590cc) I'd rather not push them to their absolute limit, so if I have to stop at 6psi.. thats fine. 6psi on e85 should make ~210whp |

why'd you choose awic vs tmic or even fmic? just wondering because I went through the same issue: deciding awic vs tmic or fmic.

I've used awic in supercharger setups in the past.. they're simple and work very well. Very low pressure drop and doesn't require 10ft+ of extra pipe.
TMIC would be easy but with the big NA intake, you can't really fit one in there...and I'd have to get a hood with a scoop. I felt awic was the best value. Last edited by tipsymechanic; 08-26-2019 at 08:10 PM. Reason: I can't type |

Awesome! I should be filming the first video next week. Hopefully all done within a few months. I don't have another car (that runs), so I have to do this in strategic stages on the weekends.
