Hey everyone, just as the title said, I'm a new guy here.
My 2000 f150 was recently totalled, and I'm in the market for a PSD. More specifically, a crew cab lariat, 4x4, 250/350/X even.
I have been reading up on SD's and PSDs for a few weeks now, and naturally, some questions have come up.

My planned mods are intake, turbo back, upgraded turbo, and an aggressive chip (DP?).
My goals are to be quick, good mpg, and BIG (12.5 on 41s).

How much power can I expect with intake, turbo back (maybe straight pipe), garrett bb, and say 125hp chip?

The reason I ask is because I am currently searching for a 2000, with forged rods. Will the PMR rods hold up to this? I know people have said they are good for 400hp, is that rwhp or crank? If the 01-03 7.3s can handle my stated mods safetly, and have room for more mods here and there, that would be great. Searching for a 2000 cc lariat 4x4 PSD is a very specific and difficult thing to do, especially trying to find a lower mileage one with a 4r100. If I can broaden my search to include the 01-03 then I might actually be able to find one!

TIA, and sorry for such a long-winded post.

First off welcome!!

Sorry to here about your 2000 f150.

400 RWHP limit set for PMR. I would search for any year and not worry to much about the rods. Your not rod shopping are you...truck shopping /ubbthreads/images/graemlins/biggrin.gif A 125 tune will give lots of breathing room before 400 RWHP.

I would also look for a ZF 6 speed truck...but thats just me /ubbthreads/images/graemlins/wink.gif

With the mods your talking about rods are not an issue. You really aren't talking much over 300 HP 350 tops at the wheels, and thats really stretching it with custom programing. To my knowledge that 400 is rear wheel. I sincerely doubt you will even come close to 300 Hp at the wheels with 41's even with a BB. My truck is an 01' dyno'd 314 with nearly identical mods to what your talking about. Trannys falling out are way more of a problem that rods are. Broaden your search.

Bella - thanks for the welcome!

ZF 6 speed? not sure what that means...is that the MT?

i really don't want to be messing with shifting, i'll bite my lip and get the 4r100....and call BTS when that goes out. or the other place here in cali, woods or something. That's why I'm trying to locate a low-mileage one, with little towing under it's belt.

i've come to the realization that if i am approaching 400hp, then rods would only be a minor detail, when compared to the $$$$$ and time i spent getting to 400hp.

I don't plan on towing anything, and I'm not going to go all out drag racing. Just want it to scare hondas while sitting up on 40-42s, and get better mpg than my f150 (rip little buddy, rip)

thanks!

 

[rman]

Kanman thanks for the info! Good to see the comparison in your truck.

You say that it'll be hard to break 300hp with the big rubber on there, but the crank will still be putting out X amount of HP, right? meaning the internals itself will still be subjected to teh same things....it's just a matter of power loss thru tranny/tires/etc.

either way, it looks like i'm safe!!!

what are you two putting down in the 1/4?

 

[67Shorty]

Yes, your crank and tranny and rear end are all seeing the same #'s. The reason for the different numbers for different tire sizes, is the tire size affects your final drive ratio, and hence, your total gear multiplication of torque (bigger tires lower the gear multiplication, so you put out lower RWHP and RWTorque.)

 

[rman]

i would regear, of course. i drove an X on sunday, with 35s, and my guess was it wasn't regeared. Definitely a slouch!

thanks for the input guys! (and gals, if any)

 

[rman]

i read somewhere that with a turbo upgrade, i'll need bigger injectors....which brings me closer to bending a rod.

is this true?

 

[duallyduty]

Depends on which injectors you plan on going with. I'd definitely stay away from Mini-Me's or any thing with 530 in it if you plannnig on sticking with the PMRs. My truck didn't last 300 miles once I did the injector upgrades, but maybe that was just my truck. Anyways, good luck with what ever you choose to go with and welcome to TDS.

 

[harmonjustin]

i will sell you my truck. it cost me $90 to fill the pig up today. 70,000 miles. it will be in vegas this weekend.

I have only ever seen folks post HP numbers from a rear wheel dyno around here, never otherwise. Truck has gone 15.5 in the quarter, just under 10 in the 1/8, 9.98 i think? I think the only think you arent safe for is the "mod bug" once you get started its hard to stop /ubbthreads/images/graemlins/biggrin.gif

 

[thesprdty]

I think you should be safe with a mild injector,like pwrstrokindually said... stay away from the big stuff unless you want to replace the rods. My truck did 15.201 with the mods i have(with 237,000 miles on the truck) witch is plenty fast to whoop up on some rice poppers lol

 

[DENNY]

Wellcome
Big tires will hurt MPG and you will not be quick unless you regear the axles. You will all so need to keep an eye on EGT'S with ANY power increase.
DENNY

 

[rman]

thanks denny.
i plan to regear to at least 5.13 when the tires go on, that's a given.

can't i get big injectors, and not utilize their full capability? like via tune? just to leave room for the future?

Haha, that's like giving guy a bunch of one dollar bills and sending him to a strip club and telling him not to get a table dance. Can you resist the temptation? I'll be honest and the first to say that I can't.

I have a 6 position chip that David @ DI Performance specifically burned for me to utilize my power and also a tow program for the least amount of fuel. Given, the tow mode had a lot more power than my truck ever had, but I was always tempted to want more so I just flipped the switch and raced a buddy twice...and that was all she wrote. 2 passes and burnt up my BD t/c and upgraded to an ATS 5 Star. 300 miles later and then my #2 PMR gave out and made a nice 4"x3" window on each side of my block and several new drain holes in the oil pan.

I'd say go for it if you can be happy with the tow program ONLY as that's the least amount of fuel, but still blows away any programmer alone if you have the upgraded GTP-38R. But if it was me, I'd play it safe and upgrade the rods FIRST to prevent a mishap and have to rebuild a new engine at a MINIMUM of $10,000 .

 

[rman]

whats a ballpark figure on rods + install?

how would you rate the ATS + WW vs. the GTP38R?...i assume the GTP42 or hwatever and H2e are much more extreme than the gtp38r?

thanks for all the help guys, i know i'm probalby coming across as a complete noob, and that's because i am pretty much clueless.

I will continue to read, and use the search button of course

It doesn't sound like you are too worried about mileage as stated in your post. Bigger tires,lift, turbo, injectors, chip, 5:13's, etc...
you must have a large roll to burn as well..
Lets see; exhaust 4" turbo back $500+, Chip with custom burn for bigger injectors $400+, gauges - tranny temp, EGT, boost- $300, Free breathing intake $100 tymar or AFT II-$350, That covers it for the inexpensive stuff, now to dig a little deeper; Injectors $1,800, GTP38R $1,600, the resulting tranny upgrade $2,000 Big Oil $2,000 Bigger intercooler to keep all that heat under control $1,500 upgraded Rods $2,000(PMR's won't last with this much fun stuff) All most forgot the Lift, 5:13's and BIG Rubber better get lots of spare rubber it likes to burn off quick with the all that torque. Was that 4X4 if it was don't forget the front diff will need new gears too.
If I was spending that much I wouldn't worry about mileage either.

h20wall--

i don't have a large roll to burn, this is a project as were my past vehicles, and all my future vehicles to come. I worked on my f150 for about 5 years and it was nowhere near where i wanted it to be.

At first i thought your post was a slap in the face, but after re-reading i may have misjudged the "internet tone."

The upgraded turbo, injectors, and big oil are a "maybe" future upgrade. Those are def. big/serious items.

As far as the gears are concerned, shorter gears are needed to get the big rubber moving, so I don't have to floor it and dump all my fuel just to get up and move from a red light. They ought to bring me back to the stockish final drive ratio, to restore the MPG/speedo/odo. Obviously they will still carry a huge rotational mass.

I know a guy who used to have an excursion, lifted on 35s, regeared, upgraded turbo, injectors and fuel system, etc. He CONSISTANTLY pulled 25mpg highway.

I'm not overly concerned with MPG, otherwise i'd be discussing tire pressure at HybridHonda.com or something. But I would like an improvement over the 14mpg i was getting in my f150. It was the 3.08s that killed me around town.

I am quite aware that both diffs will need gears. And after the lift, a new front driveshaft and extended brakelines.

I'm not too concerned about burning thru tires, I still abide by the laws of congeniality and speed limits. I'm not 16!! well, maybe at heart.

Thanks for the heads up,
Armand

You better not mix Big Oil + Injectors or you will be very close to having a hole in the block, settle for one or the other until you swap rods, and if you go for injectors, stage II is as high as I recommend.

I don't believe that. I think he was feeding you a line of total, pure, BS. /ubbthreads/images/graemlins/wink.gif

 

[rman]

nah, he was telling the truth....

i left out the minor detail that he has been a diesel mechanic for 10 years or so, i'm sure he's got a few tricks up his sleeve.
