Couple questions on a boosted 5.9 Magnum build.

#12
BTW, does anyone know where to get a pair of turbo headers/manifolds? I can`t seem to find any...

Unless you go with a remote STS setup you need custom headers, If you can do all the fabrication yourself great, otherwise, going to cost a fair bit I would think. Thats the reason you dont see any turbo Rams.
Ram fuel pumps run in the 45-49psi range (typo earlier?) 54psi through stock inj will be fine. Procharger kits have them seeing 100psi. B&G will be able to give you a tune, may take a couple tries though & that means sending the pcm in each time.
Im a bit confused on just what your building here.
5.2 will be stock & run no boost?
As far as what your boost requirements will be to get 500rwhp min all depends on what you build. 360-408ci builds can make anywhere from 250-500rwhp with lower cr for boost.
Mid level 408 probably only take a 5-7psi boost compared to 18-22psi for the mild 360.

Not a typo, was on my phone (as I am now) and only had the Haynes manuals to go by. But seeing as they`ll hold 100psi, I don`t think I`ll worry about 54...
This is our spare vehicle and the 2.7 skipped timing... It`s actually cheaper for me to get a junkyard 5.2/5.9 Magnum (whichever is cheaper) and just toss it in; I already have a 46RH and a 9.25... Only reason I`m saying 5.2 is because I know the small junkyard I go to has one. EDIT: The built engine will come later as I need to get the car road worthy asap...I need to do the timing belt in the wife`s 300M and she wants the Intrepid done first just in case.
Ok, so it seems to come down to this, if I balance my stock rotating assembly (adding in some decent pistons and ARP rod bolts), don`t spin it past 6k, and don`t get greedy and ask it to hold more than 500-550hp, will it stay together? I think no matter what I`m gonna get some ARP main studs and forged caps.

Now I`m just plain torn... I just found a 2-11-73 cast date 360 that my friend is literally going to GIVE me. I like the roller lifters in the Magnum, but the thicker cylinder walls and cheaper cam options are looking like a better deal on the LA360. It doesn`t have a top end so I would do the magnum head/MPI conversion...All I would have to do is notch the bell housing for the Crank Position Sensor and run the newer distributor right? I would also swap timing covers so I can run the magnum serpentine set-up.
Thoughts???
