Ran the IAG Stage 4 Extreme closed deck for 45,000 miles (115,000 miles to 160,000 miles) at ~660whp at 39psi until a GSC valvespring suddenly broke and caused a bent valve. GSC refused to respond to any of my emails and questions

Lesson? DON'T BUY GSC BEEHIVE VALVESPRINGS



------------------------------------------------------------------------------------------------------------------------------------
Ran the setup below: IAG Stage 2 block at >500whp 26-30psi for 3 years (1/2013-2/2016) with minimal oil burn/slap and minimal power loss; oil analyses posted below






IAG Stage 2 block
  • Manley Platinum Series 99.75mm Piston Set
  • Manley H-Beam Rods
  • ACL Main and Rod Bearings
  • OEM Nitrided Crank
  • OEM 11mm Oil Pump
  • Killer B Oil Pickup with Baffle
  • Gates Racing Timing Belt Kit
  • 12,000mile/1year warranty

IAG Stage V Heads
  • Flipped Cosworth Manifold with retained Air Conditioning Stock Vs. Cosworth IM comparison
  • ARP2000 Head Studs
  • OEM Headgasket
  • Manley Extreme Duty 33mm Exhaust Valve Set
  • Manley Race Flow 37mm Intake Valve Set
  • Manley Valve Spring and Retainer Kit
  • IAG Stage V headwork with Multi Angle Valve Job/Port&Polish
  • Kelford Dual AVCS 272/268 11.30/11.50mm Lift Street Cams
  • Cosworth Phenolic Spacers
  • IAG TGV Deletes
  • 12,000mile/1year warranty


Stock STi = 225whp on IAG dynojet









GT35R (not HTA86) comparisons/videos below

Dyno graph comparison (stock heads vs. IAG built heads, 272s) to illustrate how much IAG Stage V heads flow; no confounding variables because boost was kept the same as well as the turbo and all other parts of my setup.

Re: 2008 World Rally Blue STI - keepin' it simple

Robotvoice: I'll take some pictures over the weekend but 30% is a perfect balance between blocking out UV and not looking too illegal!

RMG: I got the lip 6 months ago for $230 shipped but now they are going for $160 shipped on ebay.

subydude: Thanks! Pleasure doing business with you guys :D
