Well after trying to get a definate answer and turning up with the usual ford sucks answers i will ask the ford community. I need to know which diesel engine will accomidate my 1994 Ford F150 the best. what i mean by that is would a cummins diesel or a psd be the better way to go when changing my truck over to diesel. I want a 20mpg and enough power to get me over the steep hills and offroads that i travel in eastern kentucky. I also want something that will be reliable and durable and allow me to run A/C. I realise that this question may have been asked before but once again i want an honest opinon from the guys that drive trucks just like mine.
thanks.

 

I would try and find a 7.3IDI. Only one wire to run it. Its the easiest swap.all the accessories will fit

 

If ti was me i would just sell the f150 and buy a PSD lot less time and money

 

I'm gonna have to agree with my esteemed colleague Mike, however if you are stuck on your 150 for sentimentality reasons, the 7.3 would be the easiest swap. There are members of FTE who have swapped to diesel from gas engines that can be a little more specific on their experience and can give you a lot more insight into the finer points of it. In fact, I did see a poster here a few days ago that was selling a complete 7.3 for around 2,000 buckaroo's. While the Industrial application Cummins diesel is a decent engine, those which Dodge was sticking in their light duty trucks have never been known for the reliability and power that is the PowerStroke. Hope that helps a little.

 

The main reason I suggested the IDI is because no computer. To do a psd swap, you almost need a doner truck and like Mike said, keep that one

 

The easiest to swap in would be a 6.9 or 7.3 IDI as said earlier, or a Cummins 12v.

The 6.9 and 7.3 won't have a whole lot of power unless you put a turbo on them. The Cummins 12v has good power and is all mechanical so pretty easy to swap. Plus there are a lot parts and kits to swap a cummins in.

 

My vote is the 12v Cummins.

 

If you want power to pull hills i would go cummins 12v.

The IDI's are good motors too, but if you don't find one with a turbo kit that's another thing you'll have to buy for it.

 

The 12v are getting hard to find I heard.

 

6.9/7.3 IDI or Cummins 4BT. I would say an IDI would be easiest though.

 

your best bet for a 7.3 IDI turbo would be to find one in a 93 o94 as that was when they were at their most common but even then there were huge amounts of them, and the cummins 4bt 12 valve are becoming more scarce too as people are taking them and swapping the heads and other parts from the them into later 24 valve engines to generate more power.

 

A Cummins 4BT will meet or exceed all of your requirements:
It will last 300,000+ miles.
You should expect 22-25 mpg in an F150.
The 4BT is all mechanical - wire the fuel shut off solenoid and the starter and it will run.
At 800 lbs, its weight is reasonable. Weighs less than a powerstroke and much less than a 5.9 Cummins.
The factory torque specs on my 4BT are 300 ft/lbs at only 1500 rpm, much higher than the 300 6 that it replaced. 200 HP and 400 ft/lbs is easily obtainable by swapping a larger turbo (HE341) and adjusting fuel and timing on the injection pump.


Take a look at my build-up thread of a 4BTA into a 93 F150:

Thanks all of you for the input. I am very sentimental about my truck and could not sell it. my father in law drove this truck to my wedding with my wife in the passenger seat. she got out of the truck and walked down the isle to me and after that i had to have the truck.

 

In that case then if your willing to put in the work then i would do the IDI it's a Ford keep it a Ford

Try and find a donor truck so you have everything you will need

 

I have everything
