I can produce additional intakes. They're $800 in aluminum and $1,000 USD in powdercoat including the runners (there is a core charge for the runners). Depending on your displacement, I'd recommend a GT2860 or GT3071 Garrett turbo.
It will come with a blank throttle body flange (drill it to your match your throttle body) and I can customize the bosses/fittings for MAP, brake booster, air temp, and IAC if you would like.
