Computer Module like , superchips, hypertech, jet. On a small engine like that, probably flowmaster.

Air Box

I put a fresh air filter system instead of the stock airbox and it made a HUGE difference. My 94 w/5 speed manual does not have any off the shelf chips available. If its a lower mileage engine.....SUPERCHARGE!!

Exhaust system, look around for some equal length headers for it and a free flow catalytic converter, cold air intake or a K&N in the stock box and wrap the stock box and inlet tubes with thermal barrier. A complete tune up with quality parts including a new set of plug wires if old. Look at Diablo for a chip. Purchase a electric fan kit for your truck that lets you remove your stock, power robbing mechanical fan, this is a really good HP getter here. From there, you can have your cylinder heads ported and polished, look into a cam. See if anyone makes an aftermarket intake manifold? You could also go the route of a direct displacement supercharger on this engine, good for about 50% greater horsopower.

Calgary, I'm not too familiar with how much HP a balanced 4.0 will support before having strength issues. All of the suggested upgrades would be what is nessasary to get rid of the "slugginess" you refer too. You would be amazed at the HP you can pull out a engine with all of the upgrades listed without the SuperCharger.

What part of the upgrades are you uncertain about or doubting? Do you have personal experience on the listed upgrades not producing HP? Which of the listed upgrades have you performed to a 4.0? What makes you believe the bottom end is not strong enough for a SuperCharger? I'm very curious on your reasoning for this, these are all standard upgrades that have been done over and over on every size and kind of engine out there and they do work!

Please Explain!!

Copied from another of my posts with the same topic:

"I'd say just start with the basics.

1. Clean the mass airflow sensor. A little carb cleaner sprayed on the two wires cleans them off well.

2. New, good quality spark plugs. I prefer the Bosch platinums.

3. New O2 sensor.

4. Change trasmission fluid and filter. My filter was plugged with gunk / sludge / filings after about 40k miles. It ran much better after changing filter and fluid. I put in Type F for quicker shifts, and so far, 5k miles later, seems to be working great.

5. Run 35psi in the tires.

Now a little more involved.

1. K&N air filter. I hate to recommend them, since they let in a negligable amount more dust, but it did let my engine make more power.

2. Remove the muffler and exhaust resonator. That exhaust resonator after the muffler is very inefficient. It makes things quieter at the expense of performance. I just clamped a glasspack to the tube after the cat convertor, used the existing hanger, and stuck a turndown on the end of it. You can run a tailpipe if you wish. This probably helped more than anything I did before. I even picked up a little mileage. For even more performance, just run a pipe after the cat. It'll be quiet enough.

3. Remove and clean the upper / lower intake and the throttle body. If egr is used they can get quite dirty and block airflow.

Now quite involved:

1. Headers. Need I say more?

2. High flow cat converter.

3. Comp 49-410-8 cam. This should work with the stock computer.

4. Port the cylinder heads and port match / polish the intake.

Good luck!"

I can tell you, that my '92 explorer is NOT a slug. Not exceptionally fast, but good enough to scare some ricers and burn a good amount of rubber, and that's with 193,330 miles on the clock as of this afternoon. By the way, I have NOT performed every mod on the above list. Nothing in the "quite involved" category.

I do know why one would think that the 4.0 is a slug though. I have driven a '96 explorer with the 4.0L OHV engine. That thing WAS a slug. You could tell it was constricted even more than mine was before I started modifying it. The difference is in the cylinder heads. Starting in '94 or '95, they made the ports smaller to help light off the O2 sensor and heat up the cat convertor sooner. Goodbye performance.

Pretty funny he dident have any facts to back up the blather he posted about the 4.0, How bout it calgaryred? Its pretty funny that I asked him why basic engine upgrades that arent 'Brand specific" wont work and he has no answers as to that, just comments with no meaning...troll....

Then "off with his head"!!

But seriously... I have a 94 with the 4.0 and 5 speed and I gotta tell ya, 1st and 2nd gears are pretty tough. Tough enough that the guys at the tire shop know me pretty well! I do think the 5 speed makes all the difference though, at least from what I've seen in driving a couple of automatics. Went head to head with a S-10 SS and stayed pretty even with him, and that's with him having a 35hp advantage on me, but his was an automatic. I think my 5 speed made up for the difference in hp.
