I was using a manifold made by a member on here, it used a 1UZ tb from a Lexus. It had provision for isc, no csi, had to relocate the alternator, no provision for a/c, used the stock tps. If a manifold could be made plug and play while using all the factory sensors, cruise, retain a/c, maybe just with battery relocation, that would be the shit! Of course a different i/c with opposing in/outs would have to be incorporated...hope to see a new product, I personally like the way a ffim cleans up the stock plumbing over the engine.
