2.5 12V fuel and turbo questions

My first post in a few years, I've been busy with life, sorry...

I recently acquired my truck, it's a 04 ford with a 98 12V in it. It has very obviously been previously setup as a 2.5 truck I'd guess. It had ladder bars front and rear (have since been removed but left the brackets), weight bracket mounts up front, a trick hitch on back, adjustable axle stops, 4.88 with spool up front and the rear currently has 4.10, the 4.88 set for the rear came with the truck as well. It's got electric fans, head studs, fire rings, 3 piece 2nd gen dodge style T3 manifold, hx50 w/T4 adapter, dual disc and cryo treated nv4500. Supposedly has 4k GSK, different injectors and who knows what on the dv's and timing. They didn't put a tach kit on it so I can't verify the rpm but i feel like it's got a 3k GSK in it. Pedal has too much drivability and really doesn't sound like 4k either.

I initially was wanting to make it a nice daily driver, it's a very clean truck and most everything was converted properly and professionally. It came with a set of 3.73 axles also. However, for a variety of reasons I am leaning more towards putting it back on the track. I imagine a guy can do a lot better than an hx50 and I need to pull injectors and dv's and find out what I have or get them reworked into what I need. This is not my first or even second hopped up p pump truck, but hoping for it to be the hottest one. I've been through the pump a bit, removed plate and gotten the afc where I'm more happy with it. It will run about 40 lbs of boost, which I think more timing and rpm will wake the turbo up a bit..
I'm not very knowledgeable on injector, DV and turbo sizing and terms.
From what I gather, most 63 mm turbos are supposedly good for 550-600 hp? I also hear fleece was around 800 on a 2.5 truck? Would like some input on turbo and fueling for a 2.5/ street stock truck, southern indiana. Rules don't seem to be overly consistent but I THINK they'll be using a 2.55 plug. Some rules state the turbo must be factory in a any 1 ton or smaller truck of any year make or model, some state must be stock appearing, etc.
I'd really like to get to 700 hp.
Thanks for any input.
Eric

Are you wanting to still be able to street this truck or just track only? 2.5/2.5 sb has progessed pretty far from supposedly going to be a budget class. I was told 1100 minimum at the crank to compete.

We are 4.88, 35s, port and polished head, cut on pistons, large cam, will have 13mm, all the fun supporting mods.

700-800 hp in a true 2.5 workstock class would be a nice Setup . Invest in a good turbo to fit your rules . Be careful as 2.5 workstock and 2.5 turbos from outdated class aren't
The same

Maybe just occasionally street it. Not planning to daily drive it or drive it to the track. 1100hp? Sounds like I'm out of the loop, lol dang... I might need to rethink some stuff..
I can't really find clear answers on what the common classes and rules are around here. Some say 2.5 stock appearing turbo, some are 2.5 will be checked with a 2.55 plug etc.

Rich, that's what I'm thinking, that a lot of the voodoo is going to be in the charger... thus looking for recommendations..

TheHammer, yes it is charcoal... sounds like you know the truck? I know very little about it's past. It seems to have changed hands several times since it was put together.

Thanks

Sent you a PM sir. Thank you.

This forum doesn't seem as heavily trafficked as I remember it being years ago.. I'm guessing social media is partly to blame?

Now that the season is in full swing, everyone is using battle of bluegrass rules here it seems. Lucas oil is running most of the events. If I was wealthy I'd love to go 2.6 or even 3.0. I think I'm to the point where I can make this a dedicated pull truck. I have another work truck, a backup daily driver, and a brand new gooseneck I bought a couple weeks ago. 2019 Load Trail hydro dove 32' 24k for anyone wondering, and yes I absolutely love it. Been using it for many things. Been taking on all the side jobs I can, wrenching and hauling. Toy fund money. Lol
