Bigger turbo options?

[93_444idi]

What are the options regarding putting a bigger turbo in place of my factory turbo? I realize that anything can really be used but other modifications will have to be done. I'd like to find a bigger turbo that will fit right where my turbo is, or fit with very few modifications.

I've seen a couple people are running HX-35s, how compatible are those turbos? Are they right off of cummins?

Sorry if these questions are silly, I just don't know. I don't plan on making a monster idi, I just want to get ~18 psi or so fairly easily. And with the other mods I plan on doing I feel like there will be a lot of black smoke behind me with the factory turbo.

with the factory setup you are limited by space between the firewall and the engine right where the turbo sits. any turbo with the same flange type(slipped my mind of which the factory turbo is) but your oil, and mounting may be different. In short you can bolt any turbo with the same type of flange to the flange that your turbo sits on now but clearance, oiling, bracketry and oiling may need to be changed. depending on the turbo

I think it is a T3, no promises. might be t4 but iirc its a t3

The flange is a T3...

The real big problem with the mounting on these trucks is the fact that the turbo itself is right on top of the intake hat. There was a guy over on FTE that tried to put a T04E on his truck- and the compressor won't clear the factory intake hat. In fact you'd probably have to get a custom made one to actually clear the compressor housing (and even that would be tight, from looking at it). An HX35 would face a similar problem.

If I could get ahold of a spare turbo, or be OK to have mine down for a couple weeks, I'd ship my turbo off to a turbo shop and have the housing machined out to install a T04E wheel (60 trim preferably, which I have). The T04E wheels are more efficient than the T04B wheels are, so that way you could still fit the turbo but have the larger wheel.

GHUNT, who do you have in mind to do this mod? Isnt this what Russ has done to his turbo? How much of an improvement is it? What does everyone think of the exhaust side size wise? Wondering if this along with an intercooler will help clean up the fuel from the moose pump.

 

[93_444idi]

this mod idea you have sounds interesting. has anyone attempted this before? is there enough material in the housing itself to be machined out large enough to fit the wheel? i'd like to change the bearings out in mine anyways, putting a bigger compressor wheel in while I'm at it would be ideal

 

[93_444idi]

is this the correct wheel that you're refering to?

and then this would be the compressor housing like the other guy tried that wouldn't fit?

Since every time we try anything with turbo mods the limit seems to be the intake and the intake hat [which seems goofy as hell]. Why hasn't someone simply made up a new intake manifold that is something like that used on the 99 and up PSD?

Seems to me Ford ran into the same set of problems mounting an improved turbo and solved them with a completely different intake.... no hat.. no cast manifold...

Any good reason why it could not be done on an IDI? Surely there is someone in the BOB who has enough redneck engineering to "gett'er done"... and come up with an intake that gives room for injector lines and a better position for a bigger turbo and a nice big down pipe.

Any takers?

Russ has done the 60-1 wheel on his (and a couple others) which is still a T04B wheel, but does require some machining. Personally I don't think the 60-1 wheel is a great fit for these engines but I may be wrong.

I was told by a place that balanced a turbo for me (Gpop's Turbo Shop) that they could machine out a T04B housing to fit a T04E wheel in there. The exhaust side is fine- it's a T3 Stage III which is used on all T3/T4 hybrid turbos.

It's not real cheap to do the machining though...they told me $225 for machining and that doesn't include assembly.

And yeah that's a T04E housing...they're a fair bit bigger than the T04B.

the 60-1 is a bit bigger than a to4e 60 trim but IMO it works really well. I can get that work done a lot cheaper than your quote.

Anyone try this yet beside the 7.3 turbo build on PSN? And any other suggestions on good turbos?

Russ -

How well does this work with a stock/slightly turned up pump? Or does it work best with a Moose Pump and other stuff?

 

[pennsylvaniabo]

has anyone tried something like this?

 

[Devon Harley]

no but you have hot exhuast pipe on top of the injectors lines that cant be to good and i would think it would have alot of lag

I threw that idea out over a year ago hoping someone would jump on it with a CNC Plasma cutter and make up sets of intake manifold blanks and find pre-bent pipes we could weld up to make a "PSD" style intake that would get rid of the "intake hat" sillyness.

We are locked into the old "poor mans patch" that someone came up with back in the day and have lived with it ever since.

With a decent aftermarket intake that would open the field for modern trubos and waste gates with decent routing for down pipes.

The challenge is still there, any takers? Someone has an old block and heads that could be used as a jig fixture to "make it all fit", I'm sure.
