are there any turbo kits available for the 2002 4.0 SOHC ranger?

 

I don't think there are any turbo kits available. You would have to custom make it.

 

i know that turbos are pretty much universal and most of it will have to be custom made, but after searching around i found that most turbos work from 1.8L to 3.8L engines..

has anyone ever tried this if so whatd you buy and specs?

 

it would be ALOT of money to do it....Double the cost of a supercharger

 

unless you know someone who works with them as a living...

 

i have heard of a few things in the works... cant really say much more, its just what ive heard

prolly be priced like the EE supercharger, which most say isnt worth the cost. idk

 

Here is a turbo 3.0

 

Ive come across this TWIN Turbo SOHC before...apparently they sell kits...call that number at the bottom and let us know if anyone answers.

TWIN Turbo SOHC

 

that is the kit d was talking about, its a custom setup i dont htink they ever made the kit. or if it is a kit you have to let them install it.

 

i would think that there would be some kits for the mustang out soon....

 

Why are turbo's so popular ? It seems like everybody and their mother wants to put a turbo on whatever car they have. A supercharger will have the same effect for less money and might even work better.

 

a supercharger takes poswer to make more power, a turbo, doesnt need any extra power. all it needs is exhaust flow. turbos are more efficient. im sure there are other fancy terms and stuff like that but that is what i know.

 

things in this world are expensive....

 

yep and a turbo isnt something you NEED, its a want so the price could be anything.lol

 

True but both will make whatever horsepower number you are looking for and depending on the application will work better then the other. Its not so much that one is the best and better then the rest because if it were that would be the only type of forced induction used period. That is not the case depending on what you have car and engine wise, and what you use it for all out racing or DD, will determine what is best for you.

Example: When I was younger and was going to completely mod up my focus, I did lots of research in to superchargers and turbos, there is just not enough room under the hood of a focus to have a good supercharger system, because the intake is on the back of the motor you can't put a twin screw or roots system back there and have intake runners long enough to make the power anywhere useful, and there is not a good place to mount a centrif supercharger either because where can you really put it, and the centrif kits that are out there for focus'es still make all the power near redline and that might be good for all out racing but for a DD its useless. So yeah little front drive 4 bangers yes turbos are king.

On a mustang however where there is enough room to mount up a good supercharger system. You pretty much can take your pick which you want. A twinscrew, or roots sytem will make by far the best low end torque and would work the best in a DD, and do very well at the track. A turbo set up wont have as much low end torque while the turbo is spooling up but one it gets going it should make more power even at the same boost levels. A centrif supercharger might even give the best of both worlds nice low end(better then turbo but not as good as a twin screw) and nice high end(not as good as turbo but maybe better then a twinscrew)

What is nice about centrif superchargers and turbo's they are upgradeable so if you want more power down the road or you get into race later on you can take out the old centrif superchargers or turbo's and put a bigger one in.

So back to putting something in a ranger. All out racing turbo, DD twinscrew or roots, centrif would be nice also. I am not aware of any kits to do either a few root supercharger were coming out but I don't know if they ever make it. There is a Ranger 3.0L kit out made by wipple superchargers but nothing that I am aware of for 4.0's.

 

another plus with the turbo is 3lbs of boost will make power like 5-6lbs of boost from a supercharger. idk, maybe im bias. but id rather have a turbo, turbos usually require less maintinance. plus wouldnt it be better to run few pounds of boost to achive the same power?

superchargers are great and all, but if i was given a choice id get a turbo. in turbo systems LAG is becomming less and less of a problem, who gives a crap if you dont have any power under 1200-1500 rpm... lol i know i dont.

you can configure a turbo to give you the power where you want it, im sur eyou can with a supercharger too but, i like the less boost on the engine and maybe in time you could run the same amount of boost as the supercharger makes but make even more power.

 

Explorer Express makes a 4.0 Ranger SC. IT sells for about $3995.

The one doug was tuning is an STS turbo. It's the one that mounts in the rear of the vehicle. This one is practical for a DIY guy to fab up their own kit because you don't have to hassle with fabbing up the exhaust manifolds, y-pipes, etc.

 

Doesn't STS make a turbo for our trucks? I remember there's been discussion about them before. STS is the turbo that's down underneath the truck.

 

I believe if they don't have a prefebbed kit you can easliy do it yourself. It's all about routing pipe back up to the throttle body from the rear turbo. It is the best solution for someone wanting a turbo. It was slammed pretty hard when it was introduced but it seems to be working well and producing power. It seems to be a viable option.

Personally sc vs turbo is not an issue for me, ease of installation and kit completeness is what I would strive for. Look at it this way. If one nets you 14.3 in the 1/4 mile and one nets you 14.6, what is the big deal. Dude, you're in the 14's!

Historically superchargers meet all emmissions because the exhaust is sent back through the cat and muffler. The blow-off valve on a turbo sends raw exhaust out in the open air. This is a big thing to consider wth new sniffer tests and inspections hitting everybody. The STS should solve that because it is after cat air that is turning the turbo.

 

Oh is it finally out, I gave up on waiting they kept saying it was coming cool, glad its availible

 

I will give you turbo's can make power where you want it, I have always thought it would be cool to have a multi mode chip set up for normal everyday use and have another setting for higher boost. Flip the switch for the chip and crank of the boost on the boost controler and really fly. That would be so cool.

I don't know about makeing more power with less boost though, yeah it makes sense because the supercharger takes power to run it but I don't know about that, at the high end yeah. The last dyno sheet I saw in "muscle mustang and fast ford" mag they did a good test of all types of forced induction at the same boost levels. The turbo yes made the most power yes by far actually, but the power curve was nowhere useful for a DD unless daily driving for you most of your time is spent near redline. The boost never picked up until 2500 RPM at that point the twinscrew had it by 150 horsepower. That was on a 2003/2004 cobra motor. DD I will take a twinscrew or roots system any day. All out racing twin turbo all the way.

 

The STS setup is nice and all but I would not get one because what would happen when I do this

 

^^ I dont think you are suppose to do that anyways!
