well i know yaw been there done that im gonna take yaws word but my first steps in all this is get the nv4500 upgrade everything get a 750hp clutch and solid flywheel, then get all the gauges i need. then go ahead and get my rocker holders 60lb hd valve springs, head studs, 4gsk gov kit, then have my pump took to a pro and have him do majic on it (most hp possible) through just the pump runnin a no plate. then sell my f150 to get the biggest twin setup i can afford at the moment. then maybe some 5x0.018 injectors sdx carries them for 850.00 they said its 200 hp.. question.. they said those 200 hp have little smoke to them. is that true on 200hp injectors. anyways then get sdx custom dv's or bbd competition dv's. a ats 3 piece manifold. then next year upgrade my turbos. if all tht dont get me above 450 hp then but if it does im not sayin i want 700 hp at one time bro im just sayin thats my gol and im tellin u all because i figured somebody would say hey heres the **** u need to get close. if u all know any way to get more fuel to my motor other than injectors dv's and pump work let me know. i understand a diesel gets power with more air and fuel but any tips or tricks or parts for more fuel than that please let me know

 

35/s400 is not big enough to support 700HP efficiently. 600HP is about its max.

Step up to an s300 on the top if possilbe

 

i may do that then i bought a s475 the other day and gonna try to get a hy40 for the top. im gonna get a 13mm pump in a couple days

 

What turbine does that 400 have?

 

what 400?

 

the s475 has the 1.32 AR housing and some call the turbine wheel a 96mm and others call the same wheel an 88mm, depends on where they are measuring.

 

i would go 5k gsk... and with a 13mm pump that is gonna be a rough dd

 

lots of song & dance here, the long & short of it is that buying half of the supporting mods for 700whp and installing them wont really work well.

 

wat will make it so rough of a dd

 

skip the 35, hybrid or not. the 12cm is to tight on the hot side with an external gate. even the 40 isnt that good on the cold side either. get a 62/65/12 with a modified gate.
alot of hp as a dd is not fun trust me, unless you got alot of money
