i'm thinking about upgrading the TMIC on my 2001 WRX, there are a couple of options the STI or a third party upgrade for example Subaru Impreza New Age Top Mount Intercooler --- Japspeed Performance Parts

the japspeed one would require some mods while the STI one should be a straight swap what would be the better option?

 

i have the PPP fitted and in the process of getting the up-pipe removed and the sports cat down pipe fitted will i get a noticeable improvement in power with a bigger TMIC?

 

wont notice much difference until the car is remapped for the mods done to it

 

what is the water spray and how does it work?

 

It cools down the surface of the IC by a fine spray of water directed onto the IC core (by means of a reservoir bottle, pump, plumbing and jet nozzle). It is controlled in-car by an on-dash manual and/or automatic electric switch, wired to the pump.

The incredibly fast-reacting latent heat absorption/evaporation properties of water means that the intake Air Charge Temp (ACT) can be significantly slashed for short periods, helping prevent det and increasing power at strategic periods during a drive.

 

unless you've got an uprated turbo, injectors etc then i wouldn't bother touching the top mount, wont make any noticable difference.

if your gonna upgrade the turbo etc then front mount is the way to go.

 

STi version is a very good i/c. Only worth uprgading when you do away with the TD04 though.
