i know they made a supercharger for the rangers if you do go the turbo route there will be alot of work involed you'll have to get a custom manifold made you'll have to tap into your block or oil pan to run return lines with the turbo or supercharger theres alot of factors to think about and also your truck will become a money pit!!!! no doubt about that

Icon6 Eaton M90 Supercharger

Ron Caster makes an Installation Kit to adapt the Eaton M90 Supercharger from the '89 -'93 Thunderbird Supercoupes to the 4.0 SOHC Rangers. Several people have them installed and working over on RPS... nice kit. You just have to pick up the M90 elsewhere - eBay, Supercharger Technologies!

I think you should go with the turbo. Be the first Ranger owner with a remote mount turbo system. No custom manifold fabrication needed. Check out this website: http://www.ststurbo.com/home

You could adapt the V6 mustang kit: http://www.ststurbo.com/mustang_v6
It's good for 250 rwhp on the 'stang.

I have installed a few sts kits an personally i dont like them. The concept is easy buy it beats the sh*t out of all the parts under the vechicle an the plumbing is too long. An having to run there extra oil pump an having oil lines running the whole length of the vechicle is bad an if you go off roading i realy wouldnt suggest it your likely to brake an oil line not know it an boom there goes your motor its just not worth it. In my opinion

Yep. Plus after speaking with STS, and Turbonetics you'll need to modify the hell out of your engine. Plus STS doesn't tell you this either. Turbonetics told me this. You'll also need to change your fuel pump too. The air fuel ratio is too lean at upper rpms. the stock fuel pump just can't supply enough fuel to the engine. Plus your stock engine can't handle the oil needed to lube the turbo.

oh the big question yet again has come up.... theres alot of comments on both but to sum it all up... turbo's are no easy task, a lot has to be changed in the engine to get the full potential of the turbo plus a good tune is required. As for superchargers its not as complicated as the turbo but things are gunna need to be changed like belts, pullies, etc. All in all its what the individual wants. hopew that kinda helps ya out.

In my opinnion, turbos are much better/cheaper to fab up to a ranger. I have done it before. You could fab up a turbo kit for a ranger for around low 1k. Just the supercharger adapter kits for rangers are 1500

but isnt a super charger much better for offroading since most offroading is low rpms? and the supercharger doesn't have to spool up?

If you are off-roading get a different turbo that spools lower if you want the torque and your wastegate will just be open a lot sooner. Or you can do what I'm trying to figure out, run duals, have one at full song at say 2500rpm and then have a bigger one pull you all the way up to the high revs. BTW does any one have any ideas on this setup?

Just be sure of this: Whether you go supercharged, or turbo.. get yourself a built transmission/clutch assembly so you dont go baking your underside and having to replace things left and right.. our rangers arent much good past 275-300 RHP with he weak mid-rig setup in the tranny area.

Armstrong is right, you can match a turbo to your engine that will be biased towards the low rpm range but will run out of breath at "higher" rpms. while we're on the subject, a lot of the PV (passenger vehicle) turbos are now running a ball bearing rotating assembly which greatly reduces unwanted friction and allows the turbo to reach it's speeds easier.

As far as your question Armstrong, what you described is a Series sequential setup which i don't think i've ever heard of on a PV application. It's basically two turbos mounted right next to each other with pressure-based bypass valves routing airflow to the appropriate turbo. I don't recommend even thinking about a setup like that for a PV application mainly because of packaging. But you just do not really need that kind of turbo range. you would be better off investing some time and really evaluating what you're after in your turbo and then spend the time matching a turbo to fit.

Ever hear of the Mazda FD RX7?

Sequential twin-turbochargers, with electronic boost control
(Twin Hitachi HT12 turbos w/51mm turbine & 57mm compressor)
Or the Toyota Supra MkIV turbo?

Sequential twin turbo's. 52mm/44mm (inducer/exducer)

There are TONS of older, and late model Passenger Vehicles that run sequential turbo's.




As far as twin turbos in a Ranger: Sequential turbo's on a 2.3.
Staged series turbos in a Ranger!
