mdshaw said:My '97 van/truck has no room for an intercooler so built my own water meth injection system. It injects 1gph at 5psi & adds 5 more gph at 20psi.
Since it's a '97 it's got forged rods & pistons.
Made a 3" intake & adapted the huge bucket size 6637 air filter. Installed 185/80 injectors, big hpop, new lpop, 4" down pipe & 4" exhaust. Since it's a van it has the bigger turbine wheel. Removed the mechanical fuel pump & added a Bosch with pre water separator & filter.
Jelli-Built made 8 custom tunes PHP Hydra) for it. The controller is in the top of the 4 port pillar gauge pod, along with egt, boost & trans temp.
On the Hot Street tune, stock Subaru STI's can't beat it from a stop or rolling. There is another tune -Race which I haven't used.
I have read that the intercooler will fit easily in the updated front clip. Further, swapping to said clip is a piece of cake. Or so says the internet.
