4.0L at junkyard?
Question:
I have a 94 ford explorere with every possible engine modification done to it possible, I can assure you that modifing the engine is a waste of time and money. I did not listen to the advice of many people and did it anyways. To list what I have put into it, or the HP is just a waste of time. I have put many g’s into the upgrade of this vehicle. You have to remember the weight of the vehicle your trying to upgrade, and also head the word’s of wisdom from many ford people. If you are going to upgrade the engine, the very first thing recomended by me is starting at your transmission. The Explorer 94 and lower transmission’s are just a hunk of junk, it will be the first problem you have. And that is not a cheap thing to do. Just a suggestion from someone who has already done what your talking bout! P.S. – That truck is now just sitting in the garage, and if you saw it you would probably go wow!!! Put to me, I want to drive it off a cliff, to bad it dont drive!

And why not? It’s 150-160 stock, Buick’s pushrod 3.8L V6 makes 205Hp stock in the new lesabres/park avenues and 245hp supercharged. 50% more would be 75-80 more, so 225-240hp… not hard at all if you know how to build a motor. > Just for thinking purposes, why do you think it’s hard to find upgrade’s for > the Explorer in magazines and shops?

Just because a "well known shop" built it doesn’t mean it was done right. To make more HP with *ANY* engine, combination of components is the key. you could bump compression, go to a huge cam, bigger valves etc, and slap on the stock computer and actually have LOST horsepower. An aftermarket chip with a hot engine won’t guarantee gains… they were made to increase performance on a *STOCK* motor… go a bit heavy on mods for the engine, and the computer is now so far off, even with the chip, that you lose HP. Right now, on the DIY_EFI list, there is a guy with a Chevy Blazer with the 4.3L V6. He put in a cam that has about 25-30 more degrees duration at .050 lift and .070 more valve lift… the engine still runs the same as stock. He’s still running all external components (exhaust manifolds, intake etc) stock. I had the same vehicle back in 93, and by replacing the exhaust manifolds with Edelbrock TES headers, adding a 3" cat back exhaust, K&N air filter, chip and thermostat, I ran 14.7’s at 94MPH all day long! It would also light the 295-50-15 rear tires when it shifted into 2nd gear (auto 4 spd trans). Had I added a cam with even more breathing ability, it would have been even quicker. Unless I went overboard and got beyond the realm of adjustment the computer had. — Sponges grow in the ocean… Wonder how deep it would be if they didn’t?!
Response:
Thats the problem, you didn’t do the job yourself. Not saying anything bad about that folks that did the work for you, but really its not hard to get a lot more out of a 4.0L.. Bolt on upgrades just don’t cut it. They *CAN* help, but there are seriously deep problems with trying to beat a LOT more power out of any stock non-high-performance engine… Explorers are a funny case, Ford seemed to go out of their way to restrict the OHV 4.0L from the get-go.

Lets just say a whole lot of things that I shouldnt off. And if you think that you could add 50% more horespower that easy, your way off. Just for thinking purposes, why do you think it’s hard to find upgrade’s for the Explorer in magazines and shops? My truck was built by a well known shop called Automotive Engineering in Florida.

What the hell did you do to it? 50% more HP is easy, I could probably do it with my eyes closed… Just need some time/effort/cash (not even much cash). Just don’t believe the hype of a lot of products of increasing the HP *AND* increasing gas milage. Thats a ton-o-bullshtuff. JS

I read in the Motor Trend – Truck Trend, the 4.0L is the V6 with the most potential for muscle building. This motor is set at it’s minimun output when coming out in a stock truck. Have you ever heard of a failed 4.0? You can actually triple it’s power… the Motor Trend guys did with no major changes(includes a supercharger). The 4.0L is a sweet motor. Good Luck.

Response:
Best of luck. I don’t agree that this would be safe but it’d definetly be fun if you did survive it I’d do a compression check all the way around for starters… If you don’t have one jug with low pressure, and you haven’t noticed any oddball problems (low oil pressure, lots of valve/lifter noise, low end knock, etc) then you’re probably dealing with a decent base engine… An engine with that many miles is "well broken in".. If you need something that revs higher than the stock 5k, I’d definetly say you need to get some more precision engine parts, like light-weight pistons, a stronger crankshaft, and a ‘bigger’ cam. You’ll want to get it ported and polished, maybe even bored a bit if you’re going through all this money (not sure if boring a 4.0 OHV is an option, dunno how close the tolorances are) I remember in a previous post you said the car just "quit going" at 4000 RPM.. Now, if you were flooring it you were probably in 3rd if its an automatic… If you wern’t flooring it, you were in overdrive and you’re going to quickly be dealing with an overreving problem… You’re going to need a lower gear ratio rear axle. 3.08:1’s are common, and personally I find this axle has the best shift points.. For performance reasons you’ll want limited slip, and I have doubt the 3.08:1 comes in a limited slip flavor – time to start looking for a performance axle if thats the case. If you’re going for a distance racer rather than quarter mile, a "standard" axle is fine. I’d say long before you blow the engine you’ll probably trash the transmission if you do manage to get a lot more power out of the 4.0L… I know the A4LD is a joke, so you’re probably going to have to look elsewhere for a transmission that doesn’t suck. The Mazda R1 (manual) is on par with the A4LD in the "joke" section… I’d also say the sport isn’t the best platform for a racer… The longer wheelbase of a 4dr will give you more stability… Also I’d recomend lowering the truck as much as you safely can but as not to ruin its street drivability. Also when buying tires remember to buy tires rated for the speeds your expecting to beat out of your rig, and don’t go too wide as tires too wide just add to your drag and in wet conditions make the truck much more apt to hydroplane and land you in a ditch or into another car… I’d also definetly look into doing something about the brake system on the Explorer before you race it – trust me, its EASY to smoke those lame rear drum brakes – nothing as bad as faded brakes when you’re racing – you just can’t stop! If I changed the rear axle I’d find one with disk brakes already on it, drums suck for high speed braking, herm, well, drum brakes just *SUCK*… Then I’d see about beefing the disk brakes even more… See the Saleen Explorer, its got a "good enough" brake system for higher speed driving. As for supercharging or turbocharging… You may find a turbocharger with a variable input and such to be a better option than a supercharger – superchargers take power directly away from the vehicle. Modern turbochargers are more apt to use less power and give you the same amount of boost as a power hungry supercharger… Ok… my fingers are tired now… :) JS

Quick to judge, eh? Maybe he blew his engine up because of a bad water pump, or warped it, or someone stole the car and ran it without oil, or the oil drain plug that Jiffy lube does all the time, forgot to put it back on? I can think of a 100 reasons why he might need another engine totally. Ok. Now me. I bought a 70K mile engine at a junkyard for $600, and it cost me a bundle to have installed. If the engine block is ok, probably easier and cheaper to get it rebuilt. Figure about $1,000 to $1,800 for rings, journals, cam, valves, heads ported and lapped and etc etc.
