If your running the 4l80e having the PCM flashed to a manual is the trick allows the eng to run fine with the manualy shifted trans (Otneil) has done it running a t56 in his truck had it flashed like you want to

The turbo manifold will likely have to be made like "ghost03hemi" is out of schedule 40 so it doesn't crack like his has a few times

Srt4 injectors should cut it on 93oct or a set of 03/04 cobra injectors on e85 I use 03/04 cobra injectors on my 392 s/c 10psi setup so they should be good for e85 on a stock 5.7 at 7psi

As for fuel pump a minimum of a 255 for safety on 93 oct and a walbro 400lph if you wanted to run e85 since you will need alot more fuel

I'm an 03 I either will run a 03 manual tcm and tune with iEMS3 or convert my truck to a manual 05 pcm just really wondering which will be better for my tuning the tranny isn't the big deal.

 

•Tuning.... should I convert to a manual 05's pcm?

The tune is the most important. Without it, you wont be able to boost up............ Convert over to an 05 pcm before attempting any boosting. There's allot of problems with the 03 pcm.:blink:

 

Any ideas what all I need or a link? I've searched it and nothing comes up

This is the setup I did to my truck when I had factory rails very simple setup only thing that needs changing in the steps is dont drill the basket still remove the clips but don't drill the basket and the 400 fits right in there

For you truck being an 03 you will likely have to get an 05 assembly to do it like I did or make the factory regulator hole you have work haven't really seen the top of an 03 basket yet in person

 

OP, you are getting the very best information from those that have experience. IMO, the tuning is the real problem with the 03 or any other year for that matter. Nice street manners is hard to come by. Get your tuning strategy set up before going forward will make life much easier for you.
What tuning are you currently using?

 

I'm currently using CMR through my intune, I think I'm going to convert to an 05 PCM for the time being, then have it flashed to a manual once I het my other engine done and put the 4l80e behind it.

 

If you plan on truly making a fast Dodge truck, plan to completely scrap every piece of Chrysler engine control and go with a full standalone setup. Dodge truck PCMs are untunable for big power, end of story.

Damn, you could have broke it to him easier then that....lol

 

I would say they are good for 850hp which is what I'm shooting for and its tunable by te right cmr tuner as for the trans and an 03 PCM that's a diff story

 

With an 05 PCM no with an 03 sorry to say yes

 

So… should I switch to 05 PCM? Or iEMS3? I'm really at a stand still, cause that's my next line of attack finding a way to tune

 

I would do the 05 PCM of it were me "carols ram" had an iems3 on his 06 and didn't like it at all but he was also running 545rfe trans but that's just my choice your
Truck your choice

 

I was going to buy that off of him but, between family and work issues I lost contact with him.

 

Ps I'm going to post some pics this weekend!

 

Then I say go for it!:thumb::thumb::thumb:

 

OP, you might read through my Megasquirt thread were I attempted to do a stand alone tuner on my 03. I would have done better IMO if I had done the trans conversion first. It is now removed and I'm back on the OEM PCM with just the High Idle Mod, I recently tried a Split Second Cam Tuner and it didn't respond as advertise. I believe I have a high fuel pressure issue now and won't really work on it again until I get back from vacation.

 

I've looked in to the fast xfi 2.0 before

 

I have a 03 with a t 70 turbo hit me up if you in STL I'm interested in a trans swap I'm on trans#4 I'm happy with my tuning after 2 years of r&d but can't get the trans to hold the power I don't know how much power I'm making now but with stock injectors and a diablosport predator I ran a 13.48 at99 6psi with correct tuning fuel pump, map and injectors at 6psi it made a huge difference no times yet

 

Good to know that there's another turbo 03 in mo! Haha I've got a built trams in the stick currently but I'm slowly building a 4l80 for it. What pump, injectors, and map did you go with?

 

im using aem 320lph fuel pump 62#injector dynamics injectors srt map tuned by diablotoona just got new 4.56 gears not install yet.my trans was rebuilt by a shop here in town first time they said they beefed it up second time said it would hold but i burn cluches out but ive been using there custom converter when the last trans worked it worked awsome but let go on the hiway while testing with overdrive off and trans temp around 230 but i have raced from a roll wich is not good at all on that trans but its fun

 

Is that an inline pump? I'm putting a wallbro 400 into my factory basket

 

putting a wallbro 400 into my factory basket

Going to do the same on my truck. The twin oem pumps drop pressure down from 59 to 54psi fuel pressure at the top end of 3rd gear.

 

:dance:Sweet!:dance:

I'm glad there's a few more 03s out there with a turbo. :thumb::thumb::thumb:
4.56 gears will help take some of the load off of the trans to help it last longer. The 03s do have an advantage in the 1/4 mile with the 545rfe. They hold 3rd gear. Any turbo set up pics?opcorn:

 

You're familiar with this, is an srt4 tip and and srt4 map the same sensor? Which one do I need?

 

my pump is intank you want the map beware more than one type 2.25 bar and 3 bar both work in the srt4 without tuning change but you should tune wich one you buy i have some pics ill post of my build my turbo is under the truck but not sts i made everything all 3 inch tubing which helps driving on the street part throttle boost was a problem before this set up now can be daily driven and tow small trailer without leaning out and sputtering whenever you lug it

 

I have a 2.25 map, I was worried I bought the wrong one, haha. Hell yeah post some pics

 

With the 3 bar sensor you loose tuning smoothability of that makes sense. Unless you really need a 3 bar sensor you have better fine tuning with a 2.25

 

Good deal it got this one lol

 

2.25 is what I'm running has anyone converted to diesel master cyl for boost launch

Good info in this thread, hope it helps :thumb:

 

Not sure if you've seen my new turbo set up. :brows:

 

You all think I should go up in gears? Factory 3.90 street driven on nitto 285/45/22 am track tires are 28/11.5-16 like to run 4.56 but don't want to run out of gear in 3rd at the end of the 1/4

 

If you shift at 62-6500 you will be fine till 11.5 range running clean out of third. If you can't shift that high or plan to go faster run diff gear

 

4.56 gears would be good until you get some real power. 4.10s would help load up the boost. And if you have some very serious power, 392 or even 355 gears. Turbo's love load.:thumb:
