Turbo Build

[jaed_43725]

I have a 88' F250 that I will be selling after I get back from Afghanistan and will be buying another 4 door or maybe extended cab F250 or single rear F350. (If anyone is interested I will be selling it for $3000 upon return) I was thinking about going to a PSD but have decided that I would be money up if I just did an IDI build. My price limit is about $5000.00 for the build and I would like to make about 750 lb/ft.

So my question is, is it feasible to take the engine apart and throw in some 17.5 or 18:1 pistons, some H-Beam rods and head studs? Thinking I want to either go with a custom fab deal running a turbo off a factory Cummins or PSD. Maybe do a mount like on a Subaru so its off on the side and run a IC of some sort. Or just get an ATS system. What would be the best way to provide fuel for it? Would a Moose pump be sufficient, or would something like a VP44 be necessary? Also would knife edging the crank be worth it? Is there any rotating mass outside of pistons/rods that can be eliminated? Are there any roller rockers for a gas engine that will work? Also will I need to consider anything for the cam, or just leave it alone? Any oil system considerations? What about working the heads? Could I do some bowl work and come out close to my idea of a CR or are the heads in such a way that only the passages should be touched if anything? Any cooling considerations, such as better radiator, electric fans (which will be done anyway), sleeving the block, etc?

I have done much searching for potential builds, but its always someone with a bit of a fantasy. This will be a actual build and I will post pics and such.

As far as I know Russ (type 4) is the only way to get a cam other than stock (it's a regrind of your original) some of the accessories on the front of the engine can be eliminated from the belt (electric water pump, no AC, electric PS), I know that there was a custom inline pump powerstroke somewhere if the moose pump won't do it, (I can not say weather it will or not because I don't have the money for one, Mel would be better able to explain if it will meet your needs). Now for my $0.02, I know the AC is cold on my truck (can see your breath), if you don't use yours then why not run it in your intake after the IC to make it cooler?

Who has an electric water pump for them. I will keep the AC and the PS. I really like the PS is the IDIs. As for the Moose pump then I will ask Mel.

Does anyone know where I can find a cross reference list of parts between the IDI and other Ford engines?

I wish I knew where to find those cross references but unless we get specific, almost everything from the gas motors will not fit the diesels. There are quite a few common parts between the powerstroke and the IDI and probably others that could work with a little tweaking. I think aa Moose Pump would be what you want for the big power, or else some claim to have adapted a DB4 head to a DB2 pump to flow the biggest amount of fuel. If you can overcome the design limitations that stop these motors from getting much beyond the 200HP/400lbs-ft of torques)high compression, I feel like a Moose pump will get you there or if not Mel's guy will probably build an even more aggressive spec'ed pumpif you have enough air and an efficient enough turbo to burn all that fuel. The fuel system is a problem but it's probably the least of the issues with the relatively low HP output of the IDI

 

[jaed_43725]

Specifically I was thinking about the valve-train. If the PSD valve-train, mostly the rockers (if they are roller), and the valve springs. I am thinking Moose pump. I have read about the 4 valve pumps and they seem to flow really well. For the turbo I was thinking HX40 or a GT35R.

Also has anyone seen a 6-71 or such type blower on a IDI. I can pick those up once in awhile for a good price. Is it feasible to put one on? Would there be clearance issues with the pump? I am not concerned about making a few things custom.

 

[jaed_43725]

Anyone have any more available input on this. I will probably start ordering parts while I am deployed. Can anyone help me out with a parts list? Like who has the best bang for the buck rods, pistons, etc.

Morso makes an universal electric drive kit for water pumps, you can get them through jegs

 

[jaed_43725]

In the case of using a belt driven system for the water pump I would rather not. If it was the kind of setup where you replace the mechanical one with a electric one then I would do it. Or if it was one where you could replace the drive unit with a motor (e.g. BBC) then yes also.

Are you going to run an electric fuel pump? If so what would stop you from putting an ac compressor down there to run a seperate ac system to cool the intake air? It would rob power but depending on how much boost your running it may offset the loss.

 

[jaed_43725]

I will most likely have to run an electric fuel pump. If I can run a mechanical one and meet my needs then I will. As for running a separate AC system to cool the charged air, I will be using a FMIC, probably one from a newer Super Duty.
