I have a 97 Ranger splash and Im going to make a STS style turbo system for it like on the camaro's and full size chevy's. What I need to know is the compression does a 97 4.0L have and the strangth of the bottom end so I know what kind of boost I can run.Oh and if any one has tried this? The reason for the turbo is because I had my A$$ handed to me by a s10 blazer with a powerdyne supercharger.

 

Honestly, why not do a supercharger setup? Everybody has been stuck on 'turboing' their trucks lately, sounds weird to me..i dunno

 

I got one word for ya.... = twin

 

I would be glad to do a supercharger but they don't have one for my year truck any more

 

The biggest thing to worry about is total engine power, not PSI. PSI is not created equal and 10 lbs on an SC61 vx 10 lbs on a T3/Super 60 will be a LOT different in total power. In my personal opinion, I would stick with a larger turbo for a 4.0 in the 60/61mm range with a .60 AR cold side and .63 AR hot side. Make sure you have a good fuel/timing management going on because too much timing or injectors going static under boost can cause some serious problems.

 

Fabricate your own manifold; then slap an M90 or M112 :) on it.. I mean you are wanting to make a turbo fit on your truck right? so a supercharger can be done as well.

 

The of belts and tensioners and all the other garbage included in an SC makes a turbo installation beyond easy.

I think some people think of it as black magic but it is seriously less involved than an SC install and a lot less maintenance and potential for problems.

 

The kit I'm going to build will look somthing like this one.I will be making everything myself. I would like to find a MAF that is programed with a bigger injector so I don't have to use a FMU, and then I will by a bigger fuel pump or booster pump.

Im not quit sure I under stand putting a big turbo on it, it's just a 4.0L I need it to make good power but reliable. If that will really work though I'm down for the challange.

 

When you run a smaller turbo, you have to turn the boost up higher to achieve the same power that you could reach with a lower setting on a larger turbo. This is due to flow characteristcs and heat created compressing the air. A properly matched turbo will make power just as fast as an SC but will make it with less loss and the ability to make a LOT more power up top.

And as far as "just a 4.0" lol, I have been building Hondas the last year or so just taking a break from muscle cars, I have run T67's on 2.2 liters and made more than 500whp on pump gas, a 4.0 can take a serious turbo and still spool it early and make power all the way up top with little to no lag and good longevity with a good timing curve.

 

Sounds good to me, I will order the bigger turbo and see how it does.

Thanks

 

is that a rear mounted turbo system?

edit: ok it isnt the same car in each pic i see.
