TOYO  INTAKE MANIFOLD - IMPORT - Part Number 6179-DP
1978-1979 Manifold 1900/2000/2200cc OHC. Also fit 20R Stock 2 STG carb only. Dyno and road tests prove the 2 bbl Dual Port gives these Toyotas as much as a 20 percent HP boost over stock manifold without sacrificing fuel economy. MPG gain was as much as 15 percent. The new 4bbl's improv HP over 20 percent with tremedous torque gains in low to mid RPM range. Check with manufacturer for DPH or DPW info. Late 1979 models wer fitted with 1980 engines and require the 1980 manifold. Easiest way to check which engine you have is location of water temp sending unit. In 1979 engines it is angled toward grill: in 1980 it points vertically toward hood. The patented Dual Port is our Street Performance/Economy Design. In the Mini's, the primary section boosts the fuel mixture to nearly the "speed of sound", about 3 times faster than normal velocity. This positively gives each cylinder a full fuel charge every time to smooth out the power stroke. when engine or driver demand cuts in the secondarires, a cold (over 30 deg colder) and dense mixture is sent down the secondary runner to be rammed into the combustion chamber by the sonic flow of the primary runner. This adds up to: 15 - 30 percent more horsepower, quicker throttle response, extended RPM range, better gas mileage, quicker starting, reduction of exhaust emissions. The two barrel mini Dual Port come standard (order "DP") to accept the stock 2 stage carburetor. However, as an alternative, most can be drilled at the factory to accept the Holley 5200 series (order "DPH") or the Weber 32/36 series (order "DPW") at no extra charge.
