Some little parts still not fabricated, but intake is now ready.

Everything is now working. Max maf values is now 73g/s with stock intake 65g/s. So about 10% more horsepower. no dtc put idle is litle high about 1000rpm. Car now report lot better fuel mileage, might be false reading.

How did you determine the sizes for the runners and plenum and throttle body? I have a lot of questions and want answers! Looks great for homemade. Why is the flange an inch or two (25-50mm) thick?

Mainly i use materials that i found in scrap pile. but also thick flange prevents warping when welding, and is easy to make smooth transient from runner to intake port. runner is litle bigger than port after it has been crush to oval shape. runner length is shortest i can make without moving dipstick, i have try various lengths on my race car and seems to be that 2NZ like short runner, when max power is about 7000rpm range. plenum and throttle bodysize are big so they don't make any limitation, in full throttle its act like 4 intake trumpet. Part throttle things i don't care, this was only test what oem ecu reacts for it. i will later modify intake to fit rwd install and install it to my 2NZ swapped 66 corona
