Only thing i disagree with is the bolt on = cheaper. The only thing not bolt on for the IDI is the turbo, you can easily build a turbo kit for cheaper than it would cost to buy a new banks / hypermax. If im not mistaken, were pretty close to having bolt on BW chargers as it is.

I was of the impression that HPOP's were more along the lines of the 2k mark.

valve springs..910-16..85
---------------------
5200

Plus $500? misc

And the best part is....
EVERYTHING is a bolt on, no custom ANYTHING which keeps COST down
While I dont necessarily disagree with the list, Its going to get you there, there is a few things you are short on... One of them is a calculator...

With your $500 misc... Your at $6205...

While I dont claim to be an expert on 7.3 psd mod pricing, I would assume a tune for 500whp is going to cost just a little bit more than $400.... The intake is going to cost you more than $50, probably closer to $100 at the cheapest, but whos counting... Going to need studs on even on a 7.3 psd for that power level, so add another $600(?)And the 910's are over $100 after shipping... But lets not split hairs here... The IDI isnt even going to get to 500whp with current fueling, with a really efficient setup and some RPM, it could get close, but its not going to get the 500 number... However, the IDI will make 350-450whp for cheaper than a 7.3 will.

Lets start with a factory turbo, since thats more on par with a PSD than the N/A engine is... Here is the rundown:

S362 on the ATS hotside- $600
DB4 180cc- $1500
Arp studs- $390
Exhaust (Fairly subjective, well say the same as you)-$320
SD IC- $150
Intake Mani-$125
Camshaft- $200
910's- $100
6637 intake- $100

$3485

Misc- Same $500...

So $3985 for a possible 450whp (dependant on tuning of course)...

But if we had the fuel that the psds have (238cc's), the pump wouldnt cost any more... only difference in the setup would be the Turbo, so add another $100 for a 66... So figure about $4100 for 500+whp.... Of course this is all dependant on a solid base, for either engine...

See I can play the game too...

But thats not the point... The idea we are even talking about this, is the biggest thing in all of this... The IDI is no longer a dead platform... no more dead than the 7.3 PSD, or the 6.0 (which people are dumping for cummins like no other)... Only difference is that the IDI has only had a little over a year for these parts to develop... Give it time.. the 7.3 PSD didnt start out as a 500whp engine either, it took time for an aftermarket to grow... The only thing that will determine the IDI's future is whether or not people feel like building an IDI... And as far as I see it, and partially the reason I started my venture, is the IDI has cost on its side, not to mention the fact that it can be dropped into anything without almost any fuss...

A 6637 air filter is ALL that is needed for a PSD, they can be had for $25

And studs are questionable but ok an extra $340


And where is all your custom machine work and fabrication in your IDI build price sheet. We all know that is EXPENSIVE. That has got to be an EASY 1000-1500

Custom what? Racin' included his custom intake price (or you could use factory turbo hat), turbo mounts to factory hot side, DB4 is a bolt on... only thing left is the exhaust and IC plumbing. Lots of folks here have been able to manage that for much less than 4 figures. Sure. Some folks have done a lot of fab work, but not that much is truly ~required, especially if you are starting out with IDIT. Not knocking our doubting what can be done with a 7.3 PSD, just sayin' what can be done with an IDI, and for how much $$. Especially attractive since IDI trucks abound with "clunker" price tags, PSD trucks not so much. If you own a PSD, or can get a screaming deal on one, go for it! Build the PSD! But if you own an IDI, or own nothing yet, consider the power level you can get for the price before "upgrading" to a PSD under the assumption that the IDI is impractical to get power out of. It's not. And it's cheaper up to what the DB4 will support.

Damn I didn't realize that the stock boots and intake tube worked for a relocated turbo and air filter, but I suppose its possible...

Studs for $340? Killer deal, that's a happenin' price for sure...Where at?
And as F834 said... What custom machine work? A 362 can work on the ATS setup with the right exhaust housing, but even if that didn't work... A T66/P-trim in the stock turbo frame fits right on like factory... charge pipes are both needed for both... what custom machining and over the top fab is required to make it work?

Yes, stock boots work perfect for the 6637, all you need is a 45* elbow. PVC works perfect for $4

Studs, my bad typo $430

IIRC racin has a custom 2 piece intake last I saw. I know that would cost something if not one by ones self. Not saying it is necessary, but all the numbers show have been with THAT intake, not a stock one. And isnt there head work done too(i don't know, I am asking)

As for the uppipes and turbo mount. You need to buy a "kit", not use the turbo that came with the kit but then use a 362 turbo?

The intake is quoted in the build list.

NMB2 had a valve job done, racin has nothing done to heads that i know of.

It was pointed out that "the engine" was assumed to be a factory turbo in order to make it more comparable. Even then, worst case scenario your out $250 to fab up pipes / mount. I think that is more than generous. I bought a used turbo and built my own kit with new oil line etc for less than $300, the turbo was $150

I also assume that the kit / up pipes were part of the $500 misc.

You are getting one hell of a deal if up pipes and mount are 250

And NONE of my prices are USED, if you want to do that, then cut everything I said in half to 1/3

i don't think we can still buy new stuff like that lol

our trucks are dated, but they still have capability. whats it matter which costs more? at the end of the day you will drive whatever you want.

Both engines take a bit of work to get to these levels... The 7.3 PSD has the advantage (if its a superduty) of being able to just bolt a 6pos chip on, ATS ported comp housing, and having a 275-300hp truck.

After that though, the PSD and the IDI are pretty level playing field up to about 400-450rwhp. Good aftermarket turbo's for the 7.3 are just as expensive as paying someone to put a kit like mine onto an IDI. The fuel system is more expensive than the IDI fuel system.

Racin' is right, we can take the IDI up to 400-450rwhp with new parts cheaper than you can a 7.3PSD at this point. I'm not sure why that is so offensive to some? The IDI has the advantage of Mechanical injection. 350rwhp and 475rwhp require the exact same modifications, its just a different fuel setting.

As for head work..... the IDI doesn't need it. We already seen that the IDI heads out flow the PSD head... I did it partly because I bought into all of the voodoo of the IDI, and partly because I wanted a perfect motor.


The gentleman who put the deposit down on my motor unfortunately was struck hard by Hurricane Sandy, so my CTD build is going to take a little bit longer now. I intend on a cam swap, and maxing my DB4 out to see what it does now.

I am doing a full built 4R100 behind it, as well as the 4x4 conversion and 4link before the CTD swap... Basically doing everything to my truck that was planned, except doing it with the IDI still in it, while I build the 6.7.....so we'll see what my IDI can really do by the time the 6.7 is built and ready to drop in.

while i would normally agree with you on this, this time i won't agree. Brad has/had an IDI. you guys got pissed when i threw around numbers about the psd. now you are pissed that somebody who really does know what they are talking about is offering his "side of the story" so to speak.

I can guarantee you two things. Brad has not been around or had a higher power IDI than me, and Brad has not been around higher performance 7.3's, or sold as many parts for these builds as me.

I actually just had a customer have us build a 500rwhp PSD. Want to know what it cost?

About $14,000 in brand new parts to have it done right and perform right, and tapped out at 475rwhp-500rwhp, because after that you need a full motor build if you want it to last. This isn't even labor included in the build, since most of you are DIY'ers.

That is for a new turbo kit, terminator hpop, full force injectors, head job, studs, gaskets, live tuning, intake, exhaust, billet flexplate, 4R100 with billet input, fuel feed system... ect.
