alright guys,im in the process of a new build and am trying to figure out the motor side of things.my goal is 700rwhp out of a 5.3 backed by a rmvb th400
with a 3700rpm stall thru a 8.8 in a mustang. i am planning on running a stock 5.3 with head studs ls9 gaskets,228/232 115lsa cam and a borg warner s475 or s480.it this doable? if so am i better off going t4 or t6?im currently leaning twoards the s475 t4 turbo,but if the t6 version should spool fine im good with that.car is being built as a low buck drag car that will also see street duty. your guys input would be highly appriciated

I have not done any tinkering with anything yet, infact i just asked for advice last week and havent touched anything with it yet, tune wise.

2004 5.3
223/230 114 cam
LOW RPM stall, somewhere around 3000k
borg s475 turbo using the twin scroll
no two step
E85
NO innercooler either

i cannot build any boost on the brakes, however, i have not changed my brake pedal for more leverage yet after the manual swap, i have stock calipers out back, etc.

So, trying to build boost on the brakes at the moment, does not work... lol just pushes through, this is probably due to a lot of things, listed above.

Anywho, without a two step and without fudging with the tune, probably around 25* of timing on the brake, and 12.0 afr and it blew open the wastegates in about 4 seconds on the transbrake, 9psi springs, dual 46mm precision gates.

I have not raced it, i have not done anything more then mess with the tune in the driveway and light cruise around the street, i put a hole in my radiator on friday or i wouldve been out boosting the **** out it. Ill report back once i get rolling more.
