HFS-6 in 2004 Subaru STi
 

Installed a HFS-6 kit into friends/client's Sti the other weekend.
We utilized the stock trunk tmic reservoir, but installed float switch & inlet.
Ran the 6mm "hard line" where the factory had routed their lines.
The electrical harness was routed through the rear seat / trunk support
with the 6mm "hard lines". The only thing you see that has to do with
Aquamist in the trunk is the pump.

The engine was given the same treatment.
The only clue is the injectors and their lines.
Tried to cover everything we could with wiring covers.

also did some road tuning last night.
from most of the cars that i have road tuned, I usually do not
get the sensation of acceleration from passenger seat while
data-logging. but I can say when this turbo gets close to 20 psi
the "suck you back into the seat" starts come on nicely...:D

so tune finished ~22psi with afr's 11.7~11.5:1, timing was also
added, 3~4 more degrees..

all run through factory ecu with grimm-speed boost control solenoid.
tdo6h-20g, pe 850cc, walboro 255 lph, 1 step colder plus, txs fmic,
plus somethings i'm forgetting.
