Xusia's Build Thread - Building an 818S for Dummies

[Xusia]

After tearing into the engine a bit, a couple items that needed attention became apparent:

• Burnt exhaust valves
• Broken camshaft gear

The need to address those lead me down a road I hadn't really intended to go (or at least, didn't intend to go as far as I did), but as the saying goes, "as long as you're in there..."

We started with all the normal engine maintenance stuff:

• New Timing Belt, Pulleys, Tensioner, & Water Pump
• Spark Plugs (NKG Iridium)
• Valve Lash Adjustment (which is where we found the burnt valves and broken camshaft gear)
• New Clutch (OEM Exidy)

Since we now needed to pull the heads, I went a bit overboard:

• GSC Power Division 1mm Larger Intake & Exhaust Valves
• Machined existing Cylinder Heads
• Brian Crower Single Spring/Titanium Retainer Kit

And I also did all the "typical" performance mods:

• Perrin Turbo Inlet
• Grimmspeed Phenolic Spacers
• TGV Delete
• Grimmspeed Crosspipe

And a few I'd consider perhaps a tad more than typical, but certainly recognized as valuable:

• ACT Lightweight Flywheel
• Manifold Porting
• 11mm STi Oil Pump
• Perrin Crank Pulley
• Killer B Oil Pickup & windage tray

My car already has:

• VF39 Turbo
• Modded stock injectors
• Walbro fuel pump
• Grimspeed EBCS
• Perrin Intake
• Upgraded (I forget the brand) up-pipe
• Bellmouth down-pipe

And finally, lest the transmission feel left out:

• Complete 2009 gearset (stronger, and slightly taller first-third gears)
• OBX LSD (with bolt/washer upgrade)

I spent far more money than I budgeted or wanted to, BUT I think I'm going to be very happy with the results (and at the end of the day, I'd likely be more bothered that I didn't do something "right").

FTW is estimating ~330hp at the wheels, but performance should be a bit better than that HP would suggest. The engine should also be bullet proof reliable - which is a big deal for me (for those that are just tuning in, mine will be a daily driver).

EDIT: Forget to mention the intake valves & turbo!
