Pinched this for you mate as I'm not sure with the bolt size and will hopefully help you :)
You could always do a how to for our how to section for others at a later date ;)
Newage TMIC Newage dump valve hose Flat aluminum bar (about 80mm x 20mm) to act as bridging plate You will also need a slightly larger jubilee clip for d/v hose
1. Remove intercooler and swap i/c hose assy to the new i/c, unless you have a Samco /Prodrive one.
2. Remove o/e d/v hose
3. Remove small rubber hose between induction piping and o/e d/v alloy tubing. In an ideal world, this alloy tube should be removed, but looking at how it is fixed, there are some brackets fixed to the inlet manifold, so I left the pipe in place. It doesn't cause any issues)
You can see the induction pipe d/v return (Black plastic tube behind turbo) and the aluminium return hose (shiney tube) The rubber hose between them is the one that is removed.
4. Fit newage d/v hose to the Black plastic hose shown above leaving the end ready to accept the new d/v. I secured the hose with a jubilee clip rather than the awkward circular clip.
5.Remove r/h/s i/c bracket (it needs to be bent to fit the new i/c and one of the holes elongating)
6. Place newage i\c into position. You will notice that the l/h/s bracket falls about 50mm short of the i/c bracket. You will need to construct a small bridging plate from a flat bar and drill a 10mm hole at either ends .Then fix the l/h/s of the i/c using the bracket.
7. Place r\h bracket into position and note how it requires bending to make it fit, then place it on the floor and tap away. Elongate hole to allow it to be fitted to the engine.
8. Fit r/h bracket to the i/c and engine.
9. Ensure d/v hose connected and check all connections and tighten all jubilee clips.
This may not be the most popular mod as most go for the STI i/c, but the WRX intercooler is noticeably larger.
Next will be the newage undertray and Samco i/c hose (classic).
