hi hilux i saw a video of you driving and took a look at your build log. I was hoping you mite have some advice your car looks fast in the video. how do you like 20r in a 442? i think yours was stock rebuilt 20r would you add more power?
My 20R is a stock bottom end, weber 38DGES, Comp 268 cam, some port matching and my giant header. Stock, they are rated at 96 HP and 120 lb-ft of torque at 4800rpm. Mine will pull past 5500 now (havent been brave enough to go higher...yet). I cannot overpower the 10" wide tires on the rear on dry pavement, which means I really can use all the power under the hood. The only thing i would really do differently (at this point) is pony up for a 9lb LCE flywheel. With this light of a car, it only makes sense.
We can debate torque vs hp or muscle car vs sports car ad infinitum, but mine was built as a street car mainly for back roads like you saw in the video, as such, more torque is beneficial. I'm not advocating a diesel engine here, but the 20R in stock form had 20%+ more torque than the 4AG at 4800 RPM, mainly because of the displacement advantage.
