5x.018 injectors - Competition Diesel.Com

I have a 98 12v with the 180 pump in it, completely stock fuel as of right now and I’m working on using it to build a 93 fummins. I don’t want to buy parts twice for any of it but my trans and clutch won’t hold much over 600hp for the first few years of driving it. I will have plenty of air 362sxe over 480sxe, steed speed manifold ext gate, and probably 188/220 cam. Its not gonna be a Dyno or sled truck exactly just gonna be a bada$$ street truck. Im thinking I want 5x18 fully worked over injectors to get over 800hp maybe push 1000 later on when I buy 13 or just a really worked over 12mm pump. I know the drive ability of this will be probably be terrible but it will just be a toy for the most part. I just don’t know if I can turn down the injectors (sled plate all the way towards the Cab) enough to to not destroy my trans. It will have the turbos before I put in the injectors possibly not the cam tho.
If anyone has experience in turning down bigger injectors Id like to hear what you have to say. The total build will will look something like this

362sxe (362 already in)over 480sxe
188/220 maybe a small sled pulling cam haven’t fully decided
Fully benched pump from PDD
Girdle
Rod bolts
Hardened/shot penned rods
625 head studs (already installed)
Hamilton extreme pushrods
Hamilton valve springs might go to duals if Drive pressure are sky high
Pretty positive of 5x18 injectors with fully worked over by pdd
Balanced rotating assembly
Marine pistons valve relieves of .100 it’s a lot but it’s also for drop in CR
WM injection possibly to help with driving on the street
Fully built NV4500 will Kenny’s triple disc competition clutch
Fire rings

I am looking to get the engine in and running in the spring and after 2 years to pull it out or find another engine to do the full build and than go from zf-5 to the NV4500. Plans might change as I go along but I Wana know if it be doable with the current trans and turbo of turned down

If you leave your pump stock with stock dv's it'll be turned down quite a bit and help out on smoke, but you might have to add some timing so it won't run funny. Other than idle haze and some warm-up smoke, 5x18s are decently drivable. You can also open your external gate early so the engine will make less boost if you want to control power.
