i'm gonna warn you but TBS's do nothing on these cars...read the N/A section on NASIOC and see that there is proof they do nothing, and an explanation on why they do nothing (dude even posted up a dyno run with and without the spacer and the +1hp he gained fits into the +/- margin of a dyno...)

i wouldn't spend your money on it, nor is there any proof they gain mpg...

 

THROTTLE BODY SPACER
"While not a new concept in N/A performance enhancement, suppliers for this part for the EJ25 seem to be just one. Area1320 sells a EJ25 TB spacer and has dynos on their site showing around 4hp gain. However most users have reported a significant gain in fuel mileage. Somewhere in the neighborhood of 4 mpg. At $150 this could pay for itself quickly. One caveat is that supplies seem to be pretty limited as the shop makes these on a part time basis. It is not their primary business. "

last 2 are from the same thread...

 

Hmm . . . that's very convincing. . . but then again . . . his car isn't the new EJ25 NA motor with the I-AVLS.

So we can't expect the same outcomes and results for a different car with a different engine.

Maybe i'll stick with an Intake for the time being, and slowly make my way up.
Rumors state, that the new 06-07 2.5i engine is very respondent to bolt ons towards the engine, but those are only rumors, no evidence :P

 

i don't think iAVLS makes that big a difference with a TBS...

iAVLS is not the end all be all honestly...it's vtech, if you hold it in any higher regard then you are fooling yourself. what makes these cars very responsive to certain bolt ons is the ECU i believe...it being a 32bit instead of a 16bit means it can hold twice as much information and process a lot faster. that means more maps can be held and more information can be stored per sensor...iAVLS just "helps" after a certain RPM (which is not a static number since the system takes intake temp and other variable into deciding when to lock the 2 intake valves)

and the TBS isn't even an inch thick is it? i doubt within the diameter of the TBS that air will "calm" down and distribute evenly through the intake mani...again as pat pointed out on NASIOC...if something that small added 4mpg and any kind of HP...i don't see why subaru would not just engineer their intake mani with a longer neck...it would be cheaper to make new mold for the mani if they could get those kind of "numbers" posted by area1320 (or whatever their name is)

that means the 2.5i would be listed as a 27/32mpg car...which is HUGE in the U.S.A. and of course adding even a few HP gives bragging rights...

 

i totally agree with zavier.

has anyone noticed if you keep you're oil level high in your motor then the iAVLS 'vtec' seems to provide a bit more boost, not exactly a mod, but just one of those things to get a bit more from your engine. i've also found that when you first start the car, shifting at 2500rpms till the engine warms up, gives you a bit more performance.
does anyone find similar results?

its winter now here so late night the temp gets down to 46 degrees. really fun to drive the car

 

j-choww son did you get that cosmo intake yet

 

Not yet. I'm still waiting till the end of the month.

Still deciding . . . HID $250 or Intake $100 . . .

 

never mind... saw the other thread...

 

so installed the carbon front lip, carbon exhaust heat shield, and carbon door pillars, very easy, everything lined up with the OEM body panels perfect! still waiting for the side skirts and carbon foglight holders.
Subaru quoted me US$ 521 per side skirt inlc. painting and fitting. ordering a pair of painted sideskirts online incl. shipping is still few hundred cheaper lol

 

hey where did you get the carbon fiber door pillars?

 

ive seen them on ebay, but i don't know if they are real or if they are a laminate

 

yeah, got them off ebay delsa motorsport, its a single sheet of carbon, in a epoxy resin, and they are held to the door pillar using 3M. i know its pointless, but its just a suttle touch for those that tend to "eye f**k" cars.
