What's happening with the heads Stock? Porting ? Valves.? You chasing a power figure? Or a quick street car? Don't worry about the Vtc springs with BDE Gears .
bottom end is good . JWT R5's (272/9.78) are big cams ..requires port work to make use of them . with bigger valves optional. responsive street motor .. light portwork ,match port everything with JWT 264/9.5 cams turn the boost up ! power comes from the heads ,depends how much you want to spend .?
As beast said (he being my mentor figure haha) your build is more ATM a high power machine. Go back to JWT400 cams, port and match your heads, you may not need larger valves that's up to you, but personally have a look at the map on the GTX2863. Compare it to the 28RS . If you want to save money get the RS as the 2863 don't seem to pack as much punch as bragged about/claimed unless running race fuel and a properly set up engine like black beasts. Also I don't think you'll see the larger throttle bodies being an advantage unless running larger intake piping, unless someone corrects me ? As I am not 100% confident on that.
changing throttle bodies is changing part of a system ! being : intercooler pipes intercooler/s throttle bodies. simple ! you stick to 2" all the way . or you upgrade to 2.5" all the way . .
What tools are you thinking of? I'm not saying that he'll get 58mm, but he'll get an increased on stock...
Regardless for his needs there isn't really a point . I mean I kept stock throttle bodies, I only plan on going bigger when 2.5" intake pipes are put on
