Hi, yes I used an Ecotec manifold and cut the runners out of it, then fabricated runners using u-bends and water cut flanges with Toyota 4AGE throttlebodies. I used a Megasquirt ECU for Alfa-N for TPS vs RPM as you can't use MAP with ITB's.
It was alot of work and I wouldn't recommend doing it for the gain. But it did add a noticeable gain in throttle response and torque. Really needs a big cam to get the most from it.. (.500"ish 240/[email protected]" on 110 LSA I reckon).
Trumpets I ordered online from a Toyota tuner in the USA.
I now have a supercharged L67 VS Commodore and I think Turbo is much better bang for buck.
