Follow this instruction if your USDM STI TMIC came with a y-pipe.

Problem:
You will notice that Y-pipe to turbo hose is about 1" short!

Solution:
Order 2" 90 degrees ID hose here for $38 shipped. You will have to cut about 1 cm to create a perfect fit.

Problem:
Brackets will not align with the intercooler on passenger's side. It is perfectly normal for USDM TMIC to not correctly align with brackets. Why? because throttle body hose is about 0.5inch short.

Solution:
Intercooler to TB hose is about 67mm ID (too short @ 2" in length). You can order a 2.75" ID turbo hose (3" in length) from here if you decide to correctly mount both brackets. http://www.stylinmotors.com/turbohose.html

Problem:
WRX splitter and seal won't align correctly!

Solution:
order air splitter and seal kit from rally spec
RST-9085kit Air Splitter & Seal Kit MY02-03 $84

what modification would be needed to install on a 04-05 for the splitter and seal?

I am guessing just a 04-05 sti seal and splitter?
I believe so. On my 02 WRX, I had to use JDM splitter and shroud.

so I brought this 06 sti tmic and the guy said hes keeping the y pipe and everything for his new iC. So I only get the core. Can I reuse the metal cast iron part from my 06 wrx and just order the silicon y-pipe that join the cast iron part (90 degree albow connected to the intercooler to the y -pipe)? What else do I need? Please advice.

Hi,

I understand I can get the silicone y pipe, what about the matel piece the connect the intercooler to the y pipe? Do I reuse the one on my 06? So Intercooler --> Metal piece --> y pipe. Thanks.
