Quick Engine Info

What do these parts do???

Most of the engine parts listed here are made of a material many time stronger than it's stock counterpart. Some are lighter and reduce the rotating mass of the engine. This creates more power by not making the engine work as hard. Here is a quick list of the benefits of these parts:

LIGHT FLYWHEEL- Allows quicker revs, the lighter the faster
ADJUSTABLE CAM SPROCKETS - Allows tuning of individual cams by advance or retard timing
CAMSHAFT - Allows more lift and duration of cams for better engine breathing and more HP
FORGED PISTONS - Lightweight, withstands more heat and abuse than cast pistons
FORGED RODS - Stronger to withstand stress, lightweight
PISTON RING - Performance rings to withstand high cylinder pressures
STAINLESS VALVES - Stainless steel resistant to heat and corrosion, lightweight
UNDERDRIVE PULLEY - Allows better free rev, less rotating mass
STROKER KIT - Custom crankshaft, pistons, rods. Allows a bigger combustion chamber.
METAL HEAD GASKET - Prevents blown gasket from high boost pressure.

All of these products must be special ordered from japan. In just about every case here, a cheaper similar quality is available locally. Prices are converted from Yen. Import fees may apply.

Metal Head Gasket PN #00643-11115-001 $76

Note: It has been discovered that the TRD Metal head gasket is merely a 94 and up 3sgte metal gasket. So if you can find the OE toyota gasket for less go ahead and buy that. They generally run $50 or so. We are currently looking for the OE part number.
