how to decide what turbo....?
looks like I will be turbo-ing my 4.0 sohc ranger. I don't know much about turbos but I need to know how to determine what size and trim and such to start me off. Anyone good with this or know where I should go to (ie website or anything) to figure it out? I will only be running about 4-5 pounds of boost with an intercooler. I am going to be trying to do my own STS type system, the turbo will go where my big catalytic converter was and run across the bottom, under the passenger to under the driver to the other side of the frame (outside of frame). It will then run up to the front of the truck up and over the upper control arm and then down just below the frame into an intercooler that will send it back across the underside of the truck behind the vailence and up to the existing K&N intake tubing. I will not be replacing my MAF, I will just be doing my best to make it a strait shot into the stock one. I would love to run a loud blowoff valve but I am sure it will get annoying and attract unwanted attention from you know who, so it will just be a bypass valve instead. If any of you have seen the Tacoma kit, I will be working with that idea. Any help is appreciated, I will be shooting for the end of the summer to get this done if it doesn't blow my budget.
