Cheapo Slow Poke "Build"

Back Story.

I have a 2005 LGT 5EAT, Bone Stock.

Thanksgiving 2013 I took it out to the desert to play a bit. All was fine and dandy until I went for a top speed run on my way back to camp to park it. Got up to 115mph, noticed it stopped accelerating, and was going to back out a bit. Before I got a chance to, CEL came on. “Cylinder 1 Misfire”. Coasted down for about 1/2 mile, stopped. As it came to idle, heard a knock. Turned it off and back on, CEL was gone, ran fine even, just had a loud knock. Ended up driving it about 160miles with the knock to get it home.

Tore it apart and found out that #2 has a bit less piston than it was installed with.

#2 Looks like it was part of my oil consumption issue.

#2 and #4 Journals and intake cam are scored.

#1 and #3 had some scoring on the exhaust cam and journals too. Just didn’t bother with pics.

Yet, #4 the typical trouble maker, looks normal.

New Build

Short Block = $1,340

Used 12,000 mile OEM 2013 STI 257 Short Block.

The previous owner made one dyno run up to 470whp 420wtq @21psi on E85. He ran it on 19psi making 420whp 380wtq to prevent damage. He’s only selling it to help fund a closed deck block and make more power.

Heads = $722

Used D25 Bare Castings.

I was originally going to get new “B” heads and 9:1 pistons because this is my daily driver and I spend a lot of time sitting at traffic signals(stop and go) and don’t get to boost much and wanted a little more off idle/boost power. Then I decided that it’s best for me to leave the short block as is, because it’s much cheaper than going through the whole bottom end and taking it to a machine shop and then buying pistons on top of all of that. So I decided to go with “D” heads that will give me an 8.7:1 CR and that’s close enough for me and is far more budget friendly. Higher than it was, and yet still low enough not to give me any “on boost” problems with the Cali Cat Piss 91.

Cams = $200

Used 80,000 mile OEM 2005 STI Cams

Valves, Springs, Retainers, Locks = $0

Reusing my original parts.

Turbo = $0

No shaft play or oil leaks on my stocker, so just reinstalling it as is.

Intake Valve Seals = $44

Exhaust Valve Seals = $51

OEM Gasket Kit = $265

12mm OEM Oil Pump = $195

Gates Timing Belt Kit w/ Water = $265

OEM Spark Plugs = $53

BMB’s Bullet Proof TIMC Kit = $90.00

Dyno Tune = $700

Adding to this list as I go.

Red parts I still need.

First part I bought since it's the first part I broke while removing the engine.
