Damn Nate, that's awesome!
Posted this so I can actually read it since some idiot designed the rules page on maps site.
Stock Appearing (SA)
Brought to you by Competition Clutch.
Heads-Up, Pro-tree (.400) class for 4 cylinder stock appearing turbocharged or supercharged, street driven, oem frame import/sport compacts with full interior and full exhaust.
*Turbocharger or supercharger must be OEM based or a similar to OEM turbocharger.
*Common cars in this class would be WRX, Sti, Evo, Cobalt, Eclipse, Talon, and others.
Tires: DOT approved radials only. *100 treadwear or higher.
Exhaust: Full exhaust required, must exit behind rear axle.
Body: Bumpers can not be removed. *Doors must open and close from inside and outside the vehicle. *No lexan allowed. *All body panels must be run.
Chassis and suspension: All vehicles must retain factory chassis. Vehicles must maintain stock drive configuration. *Wheelie bars and straight axles prohibited.
Engine: Limited to 4 cylinder engines. Engine manufacturer must match chassis manufacturer. *Aftermarket camshafts, valvetrain, rods, sleeves, crankshafts, pistons, allowed, but must look stock externally.
Modifications: *Front mount intercooler allowed, aftermarket BOV allowed, upgraded piping allowed.
Mass airflow sensor: *Factory mass airflow cars must retain a MAS/MAF from OEM manufacturer, in front of turbo. *Cars may be converted to speed density for actual engine management, but OEM similar MAS/MAF must be on car, it does not need to be plugged in or functional. *Removable MAS/MAF sensors(Evo X, Subaru, etc) may be moved into larger pipes. *MAS/MAF sensors from different cars from same manufacturer may be used(Evo or 2G MAS on 1G DSM for example).
Wastegates: *No obviously visible external wastegates allowed. *Mostly hidden wastegates are allowed(External wastegate on uppipe on Subaru for example).
Intake manifold / exhaust manifold: Must have stock appearing intake and exhaust manifolds (Swaps between generations allowed). *Aftermarket exhaust manifold allowed, if it can be hidden with a stock heat shield.
Nitrous: *Nitrous allows on supercharged cars. *Not allowed on turbocharged cars. *All nitrous components prohibited from turbocharged cars even if bottle is not present.
Superchargers: *OEM appearing supercharger allowed. *Internal upgrades and porting allowed.
Turbocharger: *Single turbocharger. *Turbocharger must be a generally accepted “stock frame” turbocharger. *This would include stock turbochargers that came on the car, stock turbochargers with upgraded upgraded wheels or housings, or aftermarket turbos that emulate the mounting style and appearance of the stock turbo(For example MAP EF3, CBRD BBK, FP Black, Blouch Dominator 3.0XT). *Turbo must mount in oem location. *Turbo swaps from different cars made by same manufacturer allowed(VF39 from STI on WRX, Evo 3 16G on 2G DSM, etc). *Rotated turbo setups not allowed. *A factory exhaust manifold/up-pipe must be able to bolt to turbo even if factory aren’t used. *A factory downpipe/O2 housing must be able to bolt to turbo even if factory aren’t used. *PTE and Bullseye or similar Mitsubishi exhaust housing turbos not allowed. *61.5mm maximum turbocharger compressor wheel inducer size. *3.40” maximum size turbocharger inlet.
Lights: Headlights and brake lights are required (one headlight may be removed for induction).
Windows: All windows must be OEM glass.
Interior: Stock dashboard and full interior from front seats forward. *2 front seats and interior panels required. *No rear seats ok. *No gutted cars permitted. *
Trans/Clutch/Shifter: Shifter must be H-pattern. Strain gauges are prohibited. Air shifters and electric shifters are prohibited.
Manual or Auto transmissions are permitted.
Sequential transmissions are prohibited.
The use of slider, adjustable, or slipper style clutch prohibited. Three discs maximum (any type of disk material is permitted). Clutch must be manually operated by driver’s foot.
Fuel: Gasoline and E-85 permitted. *Methanol injection permitted. *Methanol in main fuel tank and E98 not allowed.
Fuel System: Electric fuel pumps only are permitted. Aftermarket fuel cells are not permitted.
Stock Appearing Unlimited (SA/U)

Heads-Up, Pro-tree (.400) class for 4 cylinder and 6 cylinder bolt-on style turbocharged cars. Turbocharger must use a stock style flange for that manufacturer.
*Common cars in this class would be GTR, 3000GT, Supra, 300ZX, WRX, Sti, Evo, Eclipse, Talon, and others.
Tires: Any size DOT radial tire is permitted. Slicks up to 26” tall.
Exhaust: No restrictions.
Body: Bumpers can not be removed. *Doors must open and close from inside and outside the vehicle. *Lexan allowed.*
Chassis and suspension: All vehicles must retain factory chassis. Vehicles must maintain stock drive configuration. *Wheelie bars and straight axles prohibited.
Engine: Limited to 4 cylinder and 6 cylinder engines. Engine manufacturer must match chassis manufacturer. *Aftermarket camshafts, valvetrain, rods, sleeves, crankshafts, pistons allowed.
Modifications: Front mount intercooler allowed, aftermarket BOV allowed, upgraded piping allowed.
Wastegates: External wastegates allowed.
Intake manifold: *Any style aftermarket intake manifolds may be used.
Exhaust manifold: *Any style exhaust manifolds may be used with stock frame turbochargers like those allowed in the SA class. *Only cast exhaust manifolds are allowed with non-stock frame/stock bolt pattern turbos like those from PTE or Bullseye.
Nitrous: Allowed.
Superchargers: *OEM appearing supercharger allowed. *Internal upgrades and porting allowed.
Turbocharger: *Single or twin turbocharger. *Turbocharger must use an inlet flange that would bolt to a factory exhaust manifold. *This would include stock turbochargers that came on the car, stock turbochargers with upgraded upgraded wheels or housings, or aftermarket turbos that are meant to bolt to a factory flange(For example SCM50, MAP EF4, CBRD BBK, FP Black, Blouch Dominator 4.0XT). *Non OEM location mounting allowed. *Turbo swaps from different cars made by same manufacturer allowed(VF39 from STI on WRX, Evo 9 turbo on 2G DSM, etc). *Rotated turbo setups allowed with stock frame turbo. *A factory flanged exhaust manifold/up-pipe must be able to bolt to turbo even if factory aren’t used and turbo isn’t in factory location. *A factory downpipe/O2 housing must be able to bolt to turbo even if factory aren’t used. *PTE and Bullseye or similar Mitsubishi exhaust housing turbos ARE allowed, but must use a cast exhaust manifold. *Single turbo 61.5mm maximum turbocharger compressor wheel inducer size. *Twin turbo 53.5mm maximum turbocharger compressor wheel inducer size. *4” maximum size turbocharger inlet.
