3.0L Replacement, Super Charging, MPG ?

Hello to all,

Was reading a few of the threads through out the Site and started thinking about more power out of my 2003 3.0L.

Anyone have some ideas, is my engine worth the effort to just add a supercharger, or do I have to consider a different engine ?

I know HP costs money and MPG isn't always in the mix but is a super charged engine going to improve or reduce MPG ?

I have considered a 5.0L and a small Diesel, but here in SoCal it isn't the easiest thing to get past the Inspection.

So I have moved to the 3.0L and where I can go with it; I don't need a lot of extra power but some would be great AND I have no experience with the 3.0L except to drive a stock one for a number of years, 50K miles.
Mine has 95K on it, but it is just so under powered it isn't funny !

If I were to look for a Short Block, what should I be looking for, any 3.0L have four bolt mains, any block better than others ?

Next would be the heads, since I read that the 3.0L Heads have problems, what should I look for when going after replacements ?

Are the SHO's 3.0L ?

Thanks ahead of time for any and all information !

Ltr

The 3.0l Vulcan is not a great platform for more power, it was a reliable engine which is why Ford made it for 22 years
No there was just the one block for the Vulcan, you have the latest version in 2003

The 3.0l SHO was a DOHC engine so no relation to the 3.0l OHV Vulcan, but.................3.0l and 3.2l SHO did use same bell housing pattern as the 3.0l Vulcan
So swap might be doable, not sure if anyone has done it
VIN would still be correct, 3.0l engine, lol, but not if anyone looked closely

Morana racing has upgrades for it, seen here: Tom Morana Racing Engines

Anything like a super or turbo charger, would require beefing up the lower end, the problem with Boost, is that if you have a "little", which most stock engines can handle, you will want "just a little more", lol, and that's when stuff breaks
How much can it take?
1 psi less that when it breaks

Not sure Calif. allows any visible modifications, the twin throttle body probably wouldn't be noticed
Check ebay for parts as well

You must have an automatic...
If I rev mine up to 4000+ rpm through the gears if I want it to go, it's already doing around 60mph in third, I never found it underpowered.

+1 ^^^

3.0l Vulcan was design as high RPM engine, you must keep the RPMs above 3,500 to get full power, does not hurt it at all

I have an auto, but I have not found it underpowered. Granted it would be a lot better with a manual, but other than the typical reluctance to downshift the auto will run it up through the gears from rest quite nicely. This afternoon it ripped of a bunch of 5k shifts and I wasn't even on it that hard.

I have a hard time thinking of a Ranger as a performance vehicle anyway, so the need for gobs of power is kinda lost on me. It will easily haul what I need and can get out of its own way otherwise.
