I have a 1993 f150 5.0 I'm looking to put a SMALL turbo charger ( I know people are going to say it is stupid and I'm not posting for you to tell me that) It is just going to be low boost like 6 psi. What vital information should I know to buy gauges for. Also it is getting professionally installed.
Not stupid, but a supercharger would be easier and there are bolt on kits, you'd probably get better results and it would be less expensive.
Oil pressure, boost, coolant temp would be one's I'd want to keep a close eye on under boost.
85e150six4mtod is right about the blower. If you wanted more than, let's say, 10 psi boost, then you would want a turbo. But a turbo has many more things that need to be installed/modified than a blower. You can get away with just slapping a blower on there (I had one for years) but you would also benefit from going to MASS Air and tuning the computer to handle it.
I already have a K&N cold air intake, what supercharger would be best and reasonable price? And it's OBD1 how do you tune that?
You can tune ODBI or ODBII systems, that doesn't matter that much. What does matter is SD (Speed Density) or MASS Air. You will find MUCH more support for tuning MASS Air than an SD system, which is why so many make the switch. A main difference between the two is that SD makes an inference as to how much air is going into the intake whereas MASS Air measures the volume and density of air and calculates how much fuel is needed. A MASS Air computer is what is found in many early mustangs and some later model trucks.
What do I need to do in order to do the conversion, is it cheaper than a t/c and will it increase performance?
Converting to MASS Air will cost anywhere from $500-1500 depending on how you do it. You can get the parts yourself or buy kits.
You can tune an SD computer but you will find it easier to do with MASS Air due to the support out in the community (there are many sites dedicated to this). Just doing this conversion alone won't get you more power but it will allow you to add things on your vehicle to increase power. As an example, if you wanted larger fuel injectors, you will need to tune the computer to compensate for that. I know there are some here that say you won't be able to add a blower w/o tuning the computer but I have done it and you might be able to get away with it depending on what you buy. However, there may be more gains to be had with being able to tune the computer after you add a blower. I'm not sure about a turbo but I would assume the same.
If you add a blower, you also might want to think about water/meth injection. The reason is because the blower will increase the temperature of the air before it gets to the intake and that means you might have detonation problems unless you pull spark. If you add a water/meth system you will definitely need to be able to tune the computer.
You can see you are opening a big can of worms here, just be sure of what you are getting into and make sure you do the proper research and plan accordingly.
To me, that looks like everything I got in my kit although I can't tell if that thing in the upper left corner is a fuel pump or fuel filter. It should be a fuel pump, if it's not then you will need one.
My opinion is that something is fishy...you won't find a 25 psi turbo for that price. And if you are going to 25 psi, I'd suggest you convert to MASS air FIRST and then put on the turbo. I'd think you will need bigger injectors before you can reap any of those rewards of 25 psi. But, like I said, I don't have experience with turbos.
