Daewoo 2.0 or 2.2 short-runner intake manifold

[pontiacjeff]

I have for sale one (1) short-runner intake manifold to fit the T20/T22 engines. I built this manifold using a stock unit, cut off the runner, machined them exact same length (8" long) and built a large plenum for it. You can mount a throttle body in the stock location or use my custom inlet pipe and 64mm throttle body. The plenum volume without tube is 3.0L, with tube is 4.0L. The change in manifold alone (from stock) moved my max horsepower rpm from 6000rpm peak to a flat 6000-6500 rpm. It gained 20whp at the peak, but it gained 40whp at 6800rpm!!!! This will fit any stock Daewoo chassis. It can be used turbo engine with stock cams or non-turbo high rpm engines with big cams. $500US. Will sell with or without extension tube and throttle body.
