I did a bit of CNC work and managed to make a pritty good manifold the worked of some time. however nothing you can do on a f8b can justify the cost when f6a's are so cheap to convert. That was my experience.
Otherwise if you want a fast car by a fast car. it doesn't matter how big you engine is it'll chew through the fuel either way.
PS no-one's getting that manifold it has a TX-5 throttle body on it and I'm gonna look at using the plenum and all that and grafting it to the f6a manifold so I can have duel stage injectors and put a huge turbo on it after I'm a fully fledged engineer and don't need my car as a daily driver anymore.
