I watched the short video of your car running with the turbos mounted like that. Nice layout by the way, and now i can see your predicament.
Can you make a video of a shed skid? i like shed skids, and so do the boys
I've made my own twin turbo kit to suit my cobra, with the turbos in the guards like that too (though flat). To do it I had to use very low profile air filters (hks mushroom filters) with one turbo slightly higher then the guard vent and the other quite low, due to brake booster and mc. i used the same turbos in the genTT kit. Their small exhaust housings REALLY helped make room.
I've got turbo heat bags / beanies over the exhaust housings, earls fireproof sleeve over the brake lines and thick shielding around mc and booster. All exhaust and inlet is wrapped.
Oil is scavenged too.
Its tight, and hot, but persistence made it happen
Did you research any other twin kits before deciding on the turbos? genTT kits use visually smaller turbos and make the numbers with very low boost.
there's a set of install instructions on the net and that covers most relevant issues you could face.
also there is a company that has made vertically laid turbos possible, i think it's called aerocharger turbo systems.
I hope it becomes possible. Because they're a rare breed twin turbo cobras
