Guys,
Realize this is an f150 site. However, I still beilieve tht hte 4.0L Cosworth 6 in my Ranger is the finest engine I've ever owned. Love to hear your opinions.

The 4.0 is a fine engine, the two that I've owned, '94 and '00, have been very reliable, but their performance is depressing.

I'd much rather have a Chevy 4.3. I had an old '94 Blazer 4.3, and a '99 S10, they are just as reliable, but will easily dust the 4.0s in performance. Finest V6s in my driving experience

 

i'd be very surprised if cosworth had anything to do with the 4.0 V-6 in the ranger. no offense intended, but cosworth is a racing engine subsidiary of ford; CART, Formula One, etc

 

Yeah, the Chevy 4.3 is definitely more powerful, but a piece of crap. Had one in a S-10, the transmission went out at 37k miles and the engine at 70k. My 2 fords have never done that

 

Isn't there a big difference between the '00 4.0 and the '01 4.0? I think that's when they went to the SOHC engine and picked up an additional 47 hp. All things the same, the new one should be able to keep up the the 4.3 GM.

 

I've got a 4.sl0w in my Exploder.....good engine but it's got 140k on it right now but has always been slow and weak from the begining but hasn't given me to many problems, I've got a freind with over 300k on his '93 Ranger with the stock motor and no major problems and it still is pretty peppy.

 

THe 4.0L SOHC is actually a Roush design.

 

I think that the 4.0 SOHC engine has good power and the 5 speed auto tranny that they have it mated to make a great match. The SOHC is a much better engine for power than the older OHV engines.

But, I do not like the SOHC for a very different reason. I only got 45,000 miles out of mine. I lost oil pressure because the oil pump drive gear slipped on its shaft. This was in a 2001 Explorer Sport, and Ford told me TS. I have since gotten rid of that vehicle, but was dumb enough to buy another Ford.
