s466 over s4t over phat bastard IS IT POSIBLE?
First off i dont know where to post this cause its a mix matched build a ppumped and stroked 6.7 with a 24v vp style head, the engine is a failed atempt to building a 2000hp on fuel common rail 
and it ended pretty bad two injector nozzles failed burning up there pistons sitting below them so i bought the motor for 18k without turbos p-pumped it and threw it in my truck with a set of mahle .040 custom pistons and a vp head putting the displacement to 7.4L the motor has a 13mm pump benched to 740cc's off my 12v, .120 lines and tubes 6x.022 sac injectors by cpp, a waterman gear driven pump fed by my old fass 95 from when the truck had a vp motor in it, for internals its got a ported and polished head fire ringed with 14mm head and mains girdle a odd ball cam billet pushrods and homemade billet rockers (guy was a machinist) and some other odds and ends I know the rest of the truck will hold the power with a tripple disk and a billet nv4500, its already got a billet dana 80 with a spool one peice driveshaft and 1480 nitro joints for the front its got a billet 35 spline dana 60 with a detroit locker 1410 joints and a haisley shaft the trransfer case is a np 241 beefed by a previous owner now for the turbos, I would like to have the ability to run my s466 to pull 2.6 then on them bored days put a s4t and a phatbastard on it to romp around town, my question is IS IT POSSIBLE? any imput or suggestions are greatly apriciated!

3 stage compounds seems a bit excessive even for competition/maximum effort trucks.
think you might be better off running two larger turbos in compound (like a 66 over a 490 or something along those lines) or run triplets in 2>1 config for faster spool...
recompressing twice just seems like it would generate excessive heat and not really gain you anything other than a blown head gasket from increased drive pressures and excessive cylinder pressures.
two people you might talk to about it though is "turbolvr" aka Carl or "smokem" aka Weston (or both) over on compD. Carl is quite literally obsessed with turbos and coming up with different compound techniques, and Weston is no stranger to the heavy competition side of diesel tuning. both are also business owners.. Carl builds and sells compound twin, triple, and supercharged compound kits, and weston builds and sells custom injectors and supplies many vendors with injector nozzles. he also REALLY knows his **** when it comes to building up the cummins...
