Default STi top mount to WRX

Is it just a plug an play to swap a 06 sti top mount into a 06 stock wrx? Do you have to tune that or will the sti cooler BOV cause issues?

I am just asking because my boss is selling me his like new 06 for 200$, an I was like why not.. just seeing if its a simple thing an if it will actually make that big of a difference.

No you don't need to tune for it. IMO its a good upgrade. Does it come with the ypipe? If it doesn't then it's not worth it.

The ypipe is like the most important and most expensive part of the intercooler. That being said if it doesn't come with it I would not spend more that 120 on the intercooler. A decent ypipe will cost you 60+, you'll also need gaskets. I picked up an 05 sti topmount for 150 including the ypipe. So use my experience as a reference


Edit:

I have a friend who bought his intercooler for 150 without the ypipe, he ended up having to spend an extra 100 for an OEM sti ypipe off of someone on here.

So your saying this:

http://www.rallysportdirect.com/Proc...ilicone-Y-Pipe


is the most expensive part of the intercooler. When the Y pipe is not even part of the intercooler. It is it's own part.

Please don't use his experience as reference!

Intercoolers are expensive to make!


I decent STI IC used goes for 200 plus BTW.

Just dropping knowledge!

That's truly a bunch of BS. If your buying a STi tmic, it should be expected that the OEM ypipe is included. If its not then it's not worth it IMO. You'll need to get a decent aftermarket(or OEM) ypipe for almost half the cost, not to mention gaskets.

Your link also doesn't include the actual pieces that attach the ypipe to the intercooler.... just saying.

if you're in the process of "stroking out" the STi block then I don't think you should a) have a problem figuring out what/why you need stuff from the WRX drivetrain b) hijack other threads >: )

Why the heck would it be expected? So how is the STi owner supposed to bolt on their upgraded topmount IC if that is the route they went? So then THEY would have to buy an aftermarket or OE y pipe when they already have one, just so they can sell their stock cooler?
If they went FMIC then sure, you get lucky and find one with a y pipe. Otherwise, no it won't come with it. I've also bolted on several STi intercoolers to WRX's with the WRX y pipe and a new silicone connector.
Think before you post.

Haha, something tells me this person shouldn't be "stroking out" their '11 STi block either.

OP, STi intercooler will be a good upgrade for your WRX. If it comes with the y-pipe, all you'll need is a longer turbo-intercooler coupler and a 3"x2.75" throttle body coupler (check me on that measurement, off the top of my head).

Helps a lot with intake temps / heat soak, especially if you're running a slightly bigger turbo (VF43 / 18g).
