yup. if your new to 7.3, read this.

when looking to upgrade your truck, its all done in steps. from the guy only wanting some basic things, to the guy just looking for a little more, to the guy wanting full blown power. this is how i personally would do it. this is not the order it needs to be done, as it can be mixed and matched in any order. this is just a general guide to get you started.

hutch and harpoon. always first, imo $50-150 the hutch and harpoon are optional. the hutch is recommended. even if you do nothing else to your truck, the hutch is recommended. this is it. http://www.guzzle7pt3.com/hutch.php the reason being, is with the return coming into the tank right next to the fuel pickup, any air in the return line is then sucked right back up into the fuel line. air is bad for our heui injectors. the harpoon mod just lets you fill up the tank, 29 of 30 gallons of it, without having to stand there for 5 hours, pumping real slow to cram the last 4 gallons in. if your already in there doin the hutch mod, the harpoon will take about 2 mins.

intake and exhaust $200-1000 i say $1k cuz stacks are not a cheap option. intake, and exhaust pretty much need to be done before anything. the oem air box is known to not seal and dust a motor, and if you put a chip on it, a exhaust is almost a requirement to keep egts in check. 90% of ppl run a 4" turbo back. 5" if you want deeper sound. but 4" is more than enough.

guages/guage pod $300+ i say 300+ depending on how many and what kind he gets (think csipsd) autometer or isspro are stand outs here. 95% of ppl will get a egt, boost, and trans. those are the three main guages you will need. unless your like joe, he has, last i knew, like 15 guages in his cab.

chip $400-600 depending on where he gets it, read this. http://powerstrokenation.com/forums/showthread.php?t=78281 if you still have a question on chip, i will call bs on you read that thread

rr $250-500 can you DIY or have to buy one, do you delete the bowl now, or just the RR. your truck as what is called a dead head fuel system. fuel goes from the tank, through fuel pump, to fuel bowl, through filter, to heads. any air that makes it past the fuel bowl has no where to go, except through the injector. like i said earlier, this is bad. a regulated return allows any air that gets into the heads, to flow through the heads, back to the tank, where hopefully you have done the hutch mod already. this is one version of the RR. http://shop.strictlydiesel.com/store.php/products/73L_Regulated_Return_Kit if you are mechanically inclined, and a DIYer, i made my own for $250. there are many versions of this, many sponsers sell it. i know irate sells it, and its mostly hard line, as opposed to braided hose like the one i posted from strictly. he dont have pics up, but this is jakes site. Irate Diesel performance в€ўPower Stroke Performance . i personally used a fuelab regulator, regular steel hydraulic fittings, and some parkerstore pushlok hose. there is some talk about whether or not fuel that is heated goin to the tank is bad, but can be fixed with a fuel cooler. thats more of a to each his own opinion thing at this point.

that sets the foundation and gets the required basics out of the way to then go farther.

studs/springs/pushrods $750-1200 these are things that are just cheap insurance for a guy with stage1 or 2 injectors, a requirement of some one goin for stage 3 injectors. studs will help keep from blowing a head gasket. ARP and H11 are the two main companies. springs most ppl just use comp 910's. push rods, pic a sponser, they can get them

hpop (high pressure oil pump). our motors use high pressure oil to push the fuel out of the injectors. here http://www.cat.com/cda/files/87775/7/pehp9526.pdf is a general overview of how our injection system works. another thread here, also with some good links is this one. http://powerstrokenation.com/forums/showthread.php?t=16958&showall=1 it is very possible, depending on mileage, and how the truck was maintained before you got it, that just by putting on a new hpop(even a stock one) you could very well have what feels like a brand new truck. the two most common ones short of full on big oil, would be the srp1 http://beansdieselperformance.com/store/index.php?act=viewProd&productId=1510 and the adrenaline http://www.dieselsite.com/index.asp?PageAction=VIEWPROD&ProdID=894 with the srp1 flowing a little more oil.

trans-depending on how far you want to go with your truck hp wise will determine this one. $750-4500 just a quality torque converter and valve body, or a BTS

the rest of the fuel system, upgraded fuel pump, anything you didnt do in the RR step. $250-?, what kidna pump did you choose, hard line or hose, AN fittings or reg JIC, kind of hose/hard line, and what didnt you do in the RR step, are the main determining costs factors here.

injectors $1000+ cores for reman stage 1's, to the skys the limit on some exotic high flowing competition only injectors.

turbo $1400 on the 38r, a simple drop in replacement for stock late 99 to early 03, to the sky's the limit again on exotic twins and plumbing. almost every sponser here can get a turbo. most of them can steer you in the right direction as to sizing and housing and wheel sizes.

to maintain durability and maybe gain some mpg, and your not looking for eye popping performance, just a little more git-up-n-go, just get you a set of stage 1's, maybe a set of 2's, (injectors). any sponser can get you injectors. some of the injector builders, or sponsers that sell them that stand out in my head are, beans diesel performance, swamps diesel, unlimited, and full force diesel, and rosewood. that is not in any particular order. any tuner can tune those injectors to be real happy with your stock turbo. if your just looking for a small increase, and dont want to have lots of power, dont let ppl talk you into spending $3k on a set of hybrids when a simple $1k stg1 will more than do what you want from your truck, thats $2k you could put somewhere else.

i said maintain durability, because anytime you turn up the hp, durability goes down. its just a simple fact. with the advances in tuning nowadays, the durability bar has been raised. these things are now living at higher power levels with out failures than even 1 year ago would fail regularly. if you talk to a tuner, thank him for that, he's the reason.

before you decide to make a purchase, call a sponser or three and ask his opinion. what he has, what he would do with your money, how he would spend it. there is not a bad sponser on here, and all are highly knowledegable. call, tap into that knowledge. there are not stupid questions. if you dont know, ask, they will help you. the only thing stupid is not asking that question you want to know the answer to.

you did not pick a cheap platform to build power on. you did however, pick a realiable as hell one. switch out to a full synthetic motor oil, such as shaeffers. change it often. these things dont last properly with dirty oil. clean oil is your friend. simple regular maintanence makes these things bullet-proof in stock form, and more durable in non-stock form. slack on maintenance and it will tell you.

there are also cosmetic things you can do to your truck. for instance, the mirrors that are standard on 02 and up trucks will bolt right up to our trucks. the tow mirrors. even the ones on a 08. you will have to change the plug on the truck, and if your goin to heat and power and turn from non heated/power/turn you will need to change some wiring in the door, and run some new wires to control the new functions on your mirrors.

the 05-07 front end will bolt up. grille, header panel, headlights, bumper and upper and lower covers. if you go complete like that, you will also need the bumper brackets.

if you just like the harley headlights, you can tub out your existing header panel to make the new headlights fit, or just buy a 05-07 header panel and it will bolt right up and the head lights will fit right in. it needs to be noted that if goin to the newer headlights, you will need the pigtail adapter, or cut and create your own to make the new light work.

there are mix and match options for front end conversions all over ebay, such as this one. http://cgi.ebay.com/ebaymotors/?cmd...49&item=200544154975&sspagename=STRK:MEWAX:IT that kit will simply bolt on.

Although there are certain sponsors mentioned in this post, and links to those sponsers, they are there for reference. And while they make outstanding products, so do other sponsors, or even other companies. dont feel obligated to buy just from them. they are there so you have a visual idea of what im talking about. Do some research and pick one or more that you like doing business with. Or, spread it around and do business with them all.

Thanks tree trimmer, very nice write up. I've got a few mods done to my 6.0, but just want to get a 7.3 for a work/tow rig. Really trying to stay away from injectors, just gonna try and do mostly bolt on stuff. Your write up was full of knowledge and answered a few lingering questions. Thanks again!
