I'm basically trying to help my father fix a 04 STI that he is trying to sell. He had to basically repo it from my brother who had done the following mods:
-Element / Hydra standalone with o2 sensor
-Walbro 255 fuel Pump
-Perrin 816cc Injectors
-Espelir JGT500 Exhaust
-Bigger tmic from TurboXs
-K&N Typhoon air intake
-Kartboy ss and bushings
-Group N hardend strut mounts
-Modded hid upgrade
-Ings Front bumper
-Jdm rear bumper skirts
( some of those have no bearing on this topic but I just copied and pasted the list)
So basically long story short the Hydra has completely malfunctioned, which Hydra tested and confirmed. The car is currently in Nashville at a shop that is helping to get it back on the road. So there are a couple options they recommended to him and I was hoping to get some input. First option would be get a new discounted Hydra from the company, which is still pretty pricey. Second, they said he could buy stock injectors and use the stock ecu(which we still have). Third, I was wondering if any companies can flash the stock ecu to run okay with the mods that have been done to the car. I did that with a s13 I had which worked out well, I'm just not really familiar with Subaru.
Basically the goal is to get the car running reliably, and as cheaply as possible so he can sell it. I would seriously appreciate any help with this, as would my dad.
