Hey guys, I'm trying to put a newage sti top mount intercooler onto my MY00 classic impreza. I'm aware there are several very good guides for doing this, and I think I have read pretty much all of them, but there seems to be one thing that none of them mention.......the bonnet scoop undertray? I was under the impression that aswell as buying the intercooler from a newage sti, I'd have to buy the matching bonnet scoop undertray aswell? Because there's no point in having a whacking great new intercooler if you keep the piddling small little intake hole you had before, right? I'm guessing that I'm wrong with that one though?

Here's my lovely bonnet scoop undertray from an sti version 7, courtesy of ebay......



And here's how out-of-line all the holes are compared to my original classic one (please excuse the crappy photoshop highlighting! - You wouldn't think I was a graphic designer would ya!)......



So my question is......am I wrong in buying the undertray from a newage sti? Or do I have to make it fit somehow? I want to avoid changing the actual bonnet scoop for the newer higher one if possible because I want to keep the car looking standard.

Thanks in advance for your help

all you have to do is line it up for air intake and re-drill and self tap new holes.

use the furthest left hole on the undertray (to the left of the criss cross bit) and fit this into the furthest existing left hole on the bonnet

then drill a hole directly opposite in right side through undertray and into bonnet strengthening bar then fit a selt tapper.

you only need these 2 to fit, drilling the rest is just overkill.

Unless you use a taller scoop it won't fit properly.

Doh! Gambit seems to have it on there okay with the original small scoop tho?

it fits grand it - squeezes up into the original scoop - i didnt trim any of the undertray just drilled the hole for the righthand side fitting

Hi Gambit, what undertray have you actually got? The one I got off ebay said it was from a version 7 STI and it's different to the one in your pic. Only slightly, but it's definitely different. Have just tried it now and The Trooper 1815 was right - it doesn't fit

Ive got a newage wrx top mount waiting to go on my sti5.
What bonnet scoop did you use to clear the newage undertray?

Thanks for the pic Gambit. If you look at it tho, it's very slightly different to mine. I'll have to take a pic of the underneath of mine to show it better. But in the earlier pics you posted of it attached to the underside of your bonet......there are indents etc on yours that aren't on mine, and ones on mine that aren't on yours.....and you haven't got a 'splitter' on yours and mine has. So there must be some different types of the 'newage' undertray?

I've decided to custom build my own now anyway, so I'll let you all know how it goes!
