seriously considering supercharging my 4.0 sohc

so, due to me moving I have to consolidate most of my cars. Im keeping my ranger becuase its the most useful car/truck I have. I also have a bike that ill be keeping.. but anyways... ive thought about it before but now I have the cash do actually do it... so i started looking around at the kits out there.

I found this kit.. http://www.ebay.com/itm/Ford-Ranger-...eddf4a&vxp=mtr

There'sa lot more info on it on rangerpowersports.com. It gives ya like, 75 hp, needs a tuner, is very reliable. I think it'd end up costing around 2500$ Generally good reviews since the next option is explorer express..

Which is more expensive but more badass. But at 4700$ you can swap in a built 5.0 engine also....

I think you can find a complete kit somewhere for probably the same or at least the kit for cheaper then $1600.

Start here:

Throwing a supercharger on a stock motor is really not worth the money. get a build lower end that will handle the power first, so you dont blow the stock motor to bits. Stock you cant go higher then 8psi, which for the $2000 really isnt worth it. drop in a stroker kit, heads, a cam, headers, supercharger and intake. get it all tuned and i bet you'll pull 350+ out of it.

yes, that's a good kit. rpcaster has been selling that for years now. you won't find a kit cheaper.

https://www.ranger-forums.com/forced-induction-n20-tech-35/started-my-rp-caster-install-126342/

read that thread. to sum it up, you're happy for a while but in the end he decided it wasn't worth it.

thanks for the info. i checked rps (forgot all about that site) and it looks like the guy who makes the kit is actually on the forums. lots of good info and judging from one guys build thread, it seems worth it.

sounds like you need to do your reasearch. as long as you dont run a stupid amount of boost the motor will be fine. also, heads cams, stroker kit? you are talking 8k+. Im not looking to make it a race truck, just looking for something that is more fun on the street.

Half the benefit is getting the low end torque and that better powerband, 75hp and that said to me is worth the money

I was reading that ad and it says the supercharger is not included. I would keep on looking.

don't keep looking, if you want to go supercharged, that's what you're gonna want to buy unless you can make a kit yourself. the supercharger can be had for a couple hundred. you're buying that kit or you aren't going supercharged without dropping a lot more or doing custom work yourself.

I think you need to read what i wrote before telling me i need to do research. If your going to do the swap, do it right or dont bother. Like i said, you can only run up to 8psi boost, and for 2 grand its not going to be worth it.

You'd be better off with a power inverted and a leaf blower.

I just talked with a guy the other week who had the rpcaster supercharger. Really liked it

Jimmyd1050 ran 6PSI of boost and had no problems. I have seen his old truck in person and was driving with it on the highway and it is fast. You will have no problems with the RPCaster kit and its not a waste of money.

it really depends on what you expect out of it. if you do it right you'll increase performance, for some people it may not be worth 2grand for the extra horsepower. but there's no denying the cool factor of having a supercharger as well, so I'd say there's even some sort of false value added there.

You clearly have no idea what you are talking about.

You do realize its NOT about boost pressure? Its all about air flow or cfm. Boost is basically resistance... Example. My gtp runs 8psi stock. If i install an upgraded cam and ls7 rockers, the motor will then flow more and will show less boost. So just because it will only boost to 6 psi doesnt really mean anything. The added hp and torque do.

I've driven a RP Caster equipped Ranger several times. Amazing fun it was. Stock pulley and all that. I actually had that exact set up on my old engine for a while when I was considering tossing it on the truck. But....I have a tendency of blowing up transmissions NA! lol. I don't like the idea of this kit and my weak manual trans.

The owner is a member here (can't remember his SN) and he reported increases in fuel economy when he was easy on the pedal. When he pulls up, all you hear is air being sucked in with the engine at idle. Thing was a blast and is worth it. Wish I had an auto.

Don't listen to the folks that say don't get it. Don't listen to 'em that say it's because it doesn't come with the M90. DURR....it says it plain and clear: the kit is a kit minus huffer. Don't listen when they say you'll need a new bottom end...you've already got forged components....and you're only running like 8lb's of boost. Will note though: several manual transmission equipped owners have experienced twisted/snapped mainshafts. Rangerboy03l2(my original idol) experienced this. Will also note: most who put on the kit and continue to up the power, seem to spin bearings, toss a rod, or pop head gaskets. Everything has their limits and most those guys who've reached those are over at RPS.

I remember seeing an rpcaster kit with the m90 for $900 over on rps. Id keep an eye out there. I'm probably going to do the same with mine soon

your right its not about the number of psi you run. (why i said upgrade the motor or dont bother) the stock motor needs upgrades to make that power worth the investment.

But put 12psi in it to make good power and let me know how long that lower end lasts.


BTW, rockers and a cam wont change your flow much. You will gain a bit of air into the cylinder, but you wont notice much difference till you do a valve job and P/P the heads.


My point. do it right, build it so it can run serious power, or dont waste the money. 2 grand is a 5L swap and will get you better power.

He doesn't care, he wants a bolt on mod to entertain him for a while and be reliable, which he's entirely on the right track.

In my eyes, doing it right would be either a 5.0 or a different truck. Why waste time building up a 4.0 v6

I put injectors in my 7.3 but didn't tear down the bottom end and add a bedplate or fire ring the heads, My goal was 325Hp reliably and I acheived that. Why build it for serious power and waste money.

I dont know why this is so hard to understand.. Spend a few hours bolting on a supercharger to gain 75hp and keep a manual ttansmission or rip an entire engine out to replace with one you get from a junkyard

I have gone back and forth on this myself (and as of yet, done neither) but It is VERY easy to understand the appeal of the supercharger in terms of "simplicity" not that it is simple, but that you can retain all your factory electronics, accessories, etc. And since I plan on getting something else anyway for funsies, a supercharged v6 would make a cool DD for when you leave THE BEAST at home. plus there's still no denying the sex appeal of a blower. even if it's partly for show.

as awesome as this is the price seems too high for wht you get. unless you have no welding skills and arent much for diy. building a custom turbo kit would be much cheaper. mount the turbo behing the passenger headlight. re route the factory exhaust ypipe to the turbo. run the downpipe along the passenger side of the engine and down along the frame back to exhaust. use an electric fan and replace the factory coolant/washer fluid resevoirs with smaller relocated containers. coolant overflow does not have to be more than 1 liter. washer jug can go anywhere. next run a small/medium front mount intercooler behind the grill.make piping and tune.

people that suggest the rear mount turbos are unaware of the oil scavenger pump issues and have no concept of custom fab work or design

quick pic of for reference and general concept.
