exhaust tube sizes

megasquirt is freakin cool. I looked into it on my built Datsun 280Z but I found a great deal on a set of triple Weber DCOE 2bbls that I couldn't pass up so I ended up ditching the 30 year old O2-sensorless Bosch EFI for 6 barrels of carbureted beauty. The original system used an airflow meter with a spring-loaded vane that was already full open at 5500RPM on a stock engine, and that on top the lack of an oxygen sensor made it difficult to tune with boosted compression, aggressive camshaft, tuned headers, etc.

At that time (~2002) Megasquirt hadn't developed MAF support yet, it was all speed-density. One of these days I'm going to put Megasquirt on something...something turbocharged. I just don't know what yet. Maybe another Datsun Z car.

its going on my turbo 3.3 build (ford vulcan 3.0 w/ morana 3.3 stroker kit). just need to get more resources together. getting books to help me w/ ignition systems and turbo mapping, along w/ some refresher course books on fi and tuning. trying to get everything mapped out so i can go thru it quickly and as painlessly as possible.
