Ok, i was going to swap out my idit for a t444e but fell upon a 89 that has a 97 powerstroke stuck in it, i am gonna tear it all out of the 89 and put in my 90, main reason is i dont like crew cab, but obviously all the parts are there to do the swap....now the "no brainer" of this story is the idi is a turd and to make it not a turd is very expensive and not enough test time on performance parts to prove reliability, so having that said i plan on running a 4" turbo back exhaust"3inch" dp, ts 6position, tymar intake, hopefully get close to 300 at the rear wheels with the zf5 tranny

 

That probably won't happen without a set of injectors. I'd say if it's running good 180-210 rwhp with the mods you picked.

 

Still sounds better than what i am getting from the idi maybe 175 if im lucky

 

Moose i thought the 6 position chip was good for 120hp gain

 

yes it is good for 120 hp if you change injectors and give it air.
the tune will not add hp alone, you need to add other things to get there.
stock injectors are only good for around 60-80 hp increase. any more than that you will need larger injectors.

 

How's the hand Tom?

I agree, injectors, injectors, injectors!

 

Yea maybe 125-150.

I just dynod my truck last week and it IMO runs about as well as a stock injector truck will run. Makes 29psi and puts out a nice haze on hard accel. It made 200hp 390lbft.
Depending on dyno you might see a little more or less.that dyno is usually stingy comparing to others.

 

As much as I love my Powerstroke, I can tell you without ANY question that upgrading a PSD costs INFINITELY more than upgrading an IDI. The IDI will cost you about $1500 for new injectors, injection pump, and turbo, and then you've basically doubled it's power / longevity / dependability. You'll spend that much alone in just injectors on the PSD. You can get a LOT of power from a PSD, but it's not cheap power. One upgrade needs another supporting upgrade, and on and on and on. So when I say infinitely more expensive, I mean it. Once you spend money upgrading something on your PSD, you'll never go back. You just keep spending more and more money on it upgrading everything you can think of. It doesn't stop.

 

the hand is healing slowly Glenn.
i now have new pains, i had the left knee done on thursday. they took close to 62 CC's of nasty looking liquid out if it, and shot 6 CC's of lubricating gel back in.
but they had to go through a muscle to get a clear shot around the tendons, ligaments, bone spurs, and arthritis.
so it feels like someone was playing drums on it using sledgehammers instead of drum sticks.

 

Annnnddd the point issss?????!!!!!????




Like its a bad thing lol?

 

My point was that the O.P.'s argument about the IDI being too much money to bring back to life and up to speed was kind of inaccurate.

 

That may be true but if you go onto the idi forum look at the r+d racin'n'drummin has gone through to get what a lot of psd have with minor mods.

 

And O.P. expressed concerns with lack of track record with IDI performance parts. I know it can be done to build a decent IDI, but it's still nowhere near as expensive as a PSD build-up will turn into.

 

I just have to be honest.I could not care any less about any idi if you paid me.don't care ...never liked them.sorry they were terrible back in the day when new and not any better now. And I have had more experience than I care to on them Lil
IMO power stroke is just a much better platform even in turd stock form. But the world is full of people that do not feel like me and that is great. It would be boring otherwise..

 

DIY intercooler +-500
Stage one injectors 1200
chip 400
hpop upgrade 450


So, 2500ish for 300rwhp. Then a 2-400 more for gauges. The mods can stop anywhere you want to stop them if you stay with a stage one injector. If you don't tow a bunch the IC could wait. The hpop isn't completely necessary if you don't tow a lot, but will help power.


Honestly a good chip with nothing else done will be a big step up from the IDI. Nothing wrong with the IDI imo, but its just not a powerful motor.
