2004 STi engine swap --- need suggestions

gymhobo · 11-15-2012, 07:50 PM

Long story short, bought a 2004 STi w/ 75k miles, blew a headgasket only 300miles after I owned it. The engine was overheating and ended up warping the block to the point where a piece of paper could fit underneath the straight edge.

So I am dropping in a new shortblock fresh from Subaru w/ 1year warranty, all new engine gaskets, valve job, copperspray gaskets, ARP head studs, decking heads.

The only other surprises I found are that I have what looks like Perrin front shifter brushings, and the infamous crack in the VF39 turbo's exhaust manifold.

I already have a new set of Kartboy front and rear shifter brushings, is it worth swaping out the old Perrin and putting in the new Kartboys? I am going to put in the rear one regardless. :thumb:

Are you using a new set of stock pistons or upgrading?

And I would replace the Perrin bushings. They could be a bit worn and it can't hurt to put in freshies.

Bushings are bushings. Keep the perrin ones in and sell the front set of kartboy for like 30 bucks on here.
