I'm usually in the truck forums, but I think you guys can help me out more. I havea 98 Ram, 1500, four wheel drive. I want to take the 318 out and put a fuel injected 440 in it. I also want to put twin turbochargers on it, but I don't know much about them. Does anyone have suggestions about what kind of turbos, how much boost, how to set them up, etc.?

 

my suggestion is to do the research as to how your setup will all go together by piecing together parts from a place your going to buy the system from, and read about what they do.

For all the hassle you're going to have by going with an injected 440, I'd recommend a large single turbo instead of twins, unless you're just looking for the "Ooh" factor at car shows. Tuning twins is more than double the work of tuning a single turbo. If you think you need twins because it'll help with "lag", i really wouldn't worry about it, other guys running properly sized singleturbo's on 318's and 360's are usually at full boostbefore 3,000 rpms, and pulling hard until redline. And with a big block, traction will likely be an issue in the first place, so the turbo not spooling instantly will actually help you run faster by not giving you violent wheelspinoff the line.

just my $.02

edit: for more info...start researching over on www.theturboforums.comthere's hundreds of hours of great reading material over there in old posts

 

You must have all the other stuff before this figured out, cause seems to me, correct me if I'm misunderstanding, these questions are and would be simple to answer once the others are answered.

 

The single turbo is a better idea. I've never set up a turbo, and was wondering what all went into it.

 

The single turbo is the best way togo. Im not too sure with V8 turbos but kno 4 cyc turbos, your going to need a new manifold, oil feed an return lines, the turbo, a wastegate, intercooler, intercooler piping, probly a new air intake, and a new exhaust, you might need, new feul injectors, a bigger feul pump too. Hmm, cant really think of much more. The most important part of a turbo set up is the spark and fuel timing, that can make your car really fast or it can blow your engine up.

 

assuming this is a boat motor? id make sure that it rotates the correct direction... i know some motors for boats have opposite rotations... its prolly ok and the correct rotation,, but hell..for all that work it wouldnt hurt to make sure!!

that would be one hell of a sick ride!

 

I have to say, a twin turbo would be most impressive. I was watching a video of a ford GT with a turbo on it, aside from the nasty power, it was slightly annoying when there was turbo lag, but when the turbo kicked in, boy watch out. (200mph in just under 30 seconds)

 

7% power increase for every pound of boost. two would be sweet!
