It will swap right in as long as the two hoses are there.

You should be able to just drop an sti top mount right in, I have a 2005 rex and a v7 top mount dropped in, nothing had to get swapped from the stock top mount to make the swap work. The Jdm v7 top mount is bigger than a usdm sti top mount and still swapped perfectly. Try to find and sti top mount with its y pipe, don't worry about the throttle body coupler, use your existing coupler.

imo, go for the ebay intercooler as the price difference between that and the STi one is well worth the absence of the cherry blossom red STi spray decal

Go ahead, by a cheap aftermarket part that pays no attention to actual air density/cooling properties. Sure, it may flow more, but it's going to also fit like crap and when you upgrade down the road, it will be worth nothing to sell.

Quality OEM parts always fit right the first time, hold their value, and work well for years.

You won't get full use out of it unless you buy an sti hood scoop, sti air splitter and sti rubber gasket. And possibly a new hood because I don't think those parts will fit an 02/03 hood.

Those cheap eBay intercooler are less efficient than an sti unit. You can probably find the results from testing done by a member here, search for it. Its a comparison between a godspeed and sti top mounts. If you just want to open the hood and wow your friends with a huge intercooler then the eBay one is fine. The link you posted is for a turbosx intercooler, that is supposed to be a good unit.

Dont bother w Ebay parts imo. If u acquire an STi intercooler. Use STi hard y-pipe or a silicon y- pipe, any silicon coupler for TB fitment and turbo to intercooler-can purchase at siliconhoses.com- u must know ur measures/ sizes needed. Purchase some t- bolts too!! , helps to slot/notch the driver side intercooler support. Long shot but a JDM hood scoop and splitter/seal will nicely finish the job for function and form.
Good luck!
