New with Turbos and have a few questions I'm doing a LS swap in a 81 Mustang and I do not know very much about turbos and LS motors.
Here is what my plans are, I'm going to use a 5.3 short block, 317 heads, LS6 intake, LS6 cam and springs, 70mm turbo, air to air intercooler, turbo 350 transmission.
Mind you, this is a very low budget build so I do not want to buy the best there is. If stock part will work then that is what I need to know. I'm trying to build a 9 second beater to play with on the street for under 5k. I know it can be done, it's just a matter of finding the deals.
My questions are:
What size injectors do I need?
Whats a good low budget fuel pump that is capable to support this?
What size stall converter do I need?
I already have the heads, intake, intercooler and bought a turbo today. So far I have 1k in the build including buying the car. I think my biggest expense is going to be the motor.

First off I would look at going with better springs for the boost. Everything else should work. For how long is in the tune so make sure it has a good tune on it.
As far as injectors 96lbs injectors may be a little big but you should be able to run them and idle fine for the kind of power your wanting to make. If you plan on E85, alcohol or anything like that then just get the 160lbs injectors now.
You could probably get by with a Aeromotive A1000 now and if you need it then upgrade to another. Also I have heard good stories about the Bosch fuel pumps people on here run.
The converter is what will make or break you. That is one place I would not skimp or your times will suffer. Call Neal Chance or someone else reputable with turbo converters and go over your combo with them. otherwise you will be chasing your tail on why your times arent where they should be.

wow that is some high dollar parts for a budget build... I would think 60lb injectors would be enough to get you where you need to be, fuel pumps just do twin walbros in tank, I do agree with springs, you should get a good double spring like a PRC or PPG spring.
5000 grand going to be tough to do a swap and turbo build but good luck. I hope you are one hell of a fabricator so it keeps the cost down!

Since I have not bought the springs yet I will go ahead and get a better set, Any part numbers?
I will be taking it to wormboy to do the tune
I will be running Pump gas
To run a turbo do I need a special stall convertor? I have several good convertors but I do not know how high of a stall I need. It is going to be just a street car with very little track time. All i'm going to do is get a baseline on what it runs then it will be off to the streets.

I can not help you with stall cause, I am not even sure if I have the right one... You may not get the right one on the first try you may have to try several, hopefully someone will be able to chime in and tell you more about that, I will post a part # for both in a sec!

The car is going to weigh about 2400 - 2600 pounds so its not going to take much hp to achieve a bottom 10 or 9's.
Here is what I have so far in cost:
81 Mustang running with a 302 $450.00 (Will sell motor and trans)
New 70mm Turbo $300.00
317 heads, LS6 intake and inter-cooler $250.00
I know a lot of the small parts is what cost but if I go over my budget it will not be a big deal. I'm just trying to see if i can do it.
If it does not work then I will put the turbo on my C5 and be done with it.

My buddy built a Fox similar to yours with a 5.3 and a 76mm. He is into the car for over double what you think you will be spending. The best its run is 10.40's @ 131 so far but is hunting for a single digit. If you can make this car run nines for more than one pass with 5K I want to hear about it.

X2 I agree entirely.

99% of the part i'm going to buy is going to be used.

Since I sold the race car I just want to do a project just to see if it can be done on a low budget. I don't want to mess with the Corvette since it is my Daily driver but I do have a backhalf 69 Nova but I don't think I will get many races on the street with it.

This is just project to give me something to do, I know it is a cheap turbo (OBX) but its a start. I could have gone out and bought a high dollar Turbo, wastegate, headers, FAST System, MSD7531 box and all the other fancy **** but then it would not be a cheap build.
If it works it works, if not I can say I tried and failed. Not the 1st time I have failed at a project.

Not pissing on my parade... I just sold a 67 Camaro that had a 698 that made over 1300hp on motor and another 800 in nitrous. I'm not trying to set the world on fire, I tried it and it cost too much money.
