Is a waste to not turbo a 2jz- they are very heavy and tall and long. A bone stock iron block 4.8 lt motor will outperform a built to the hilt n
2j in any racing discipline or on the street. Only reason to build one is they are stout enough for lots of boost. Just bolt discarded factory turbo parts on to it , that will outperform the gnarliest NA 2j, unless your just building a built bottom end and ported head for a planned turbo setup your wasting a 2j but I’m just a Moron on the Internet

If you must, you need custom ground cams, as all of the aftermarket cams are ground with almost no overlap, like all turbo cams. If your trying to make big NA power you need a bunch of poor idle 3 stroking stumbly loose converter ass overlap, and I have a 2jz ge vvti stainless long tube header for sale, for 200 bucks
