Where to buy rubber coupler for WRX TMIC to TB ASAP?

Post by High PSI »

Any local stores sell rubber couplers big enough for the WRX TMIC outlet to TB fitting? I went to my local Home Depot, biggest they had was 2". Autozone had nothing but radiator hose sized stuff. I know I can always go to www.turbohoses.com, but I'm kind of looking for something local so I can finish up my TMIC install stat. :-)

I'm actually out of CT. But it looks like this boost controller place is in NY state, so if I ordered it from them I should have it by the weekend...

Thanks for the link! I'll give them a call and see what their estimated shipping time would be.

It should be mentioned that 2.25 is not the correct size to couple a WRX TMIC to the throttle body...

Good call - I found 2-5/8" to work best.


Here's some info from my WTB thread in the part's shed:

i hope boostcontroller isnt too anal about returning something. I ordered a 2.25 id hump hose without thinking about it much. Looks like their only options are 2.5 and 2.75" id so i think im gonna get the 2.75 and some good t-bolt clamps

Is this for the TMIC to TB? I would think 2.75" would work fine. 2-5/8" was very tight...I was actually unsure if it was going to work at first, but the silicone stretched enough so it fit without any problems.

Personally, I'd recommend not going with the hump hose. The TMIC outlet more or less pushes right up against the TB, making the hump nothing more than a place for pressure to build up and try to push it's way out of the coupling. Those humps are really made for areas where the intercooler is rigidly mounded to the car and needs to be able to move independently of the engine. The way we do TMIC setups on our cars, it's bolted to the engine and nothing else, so it's a moot issue.
