HOW TO TURBOCHARGE THE 7AFE Options

[jesterwr217]

starting my own how to on turboing the 7a because there were some areas of the install where i just kinda had to make educated guesses so hopefully this will help others
Ok lets get started...
First removal:
To start off simply remove the stock headers and whatever intake you have on your car
Like nik lets start with the fuel setup:
Fist is the fuel pump. The stock 7a fuel pump is not sufficient enough to support a turbo setup so the plug and play alternative for our cars is the supra 255lph pump. First open you gas door and gas cap while doing this to relieve pressure. To get to the stock pump remove your rear seat and you will see a plate held on by 4 screws with an electrical harness going through it. remove this panel and you will see where the harness plugs into another panel, remove that harness to make the next panel more accessable. once you remove that harness remove the two lines attached to the top of the panel. the next step is to remove the 8-10 screws holding the second plate on and the fuel pump will come straight out. remove the pump and replace it with the new one then reinstall it in the car.
Now there are 2 different ways to continue this:
the first way is the "ghetto way" and is only safe to about 8psi. for this setup you will take the vortech fmu and run the bottom line to the fuel line comming from the back of the car and the top line to the fpr.



the vaccum port on the top will splice into the vaccum for the fuel pressure regulator



with this "ghetto" setup you will also use check valves in the vaccum line for your stock map sensor so it can see boost



now the correct way is forget about the fmu and the check valves, instead you replace your map sensor with the 3sgte 2 bar map



and use the supra 315cc lime green injectors



Oil Lines:
First we'll start with the feed line. You can order this kit from the same place i did and it comes with everything you will need. here The 7a has an oil temp sensor that provides a perfect tap point for the oil supply



use the supplyed t fitting and threaded fittings to create a t for the oil feed



attach the supplyed stainless steel line and we will come back to the feed line when we get the turbo in
remove your oil pan you will need to go to napa or some place like napa and get a 3/4 inch galvanized hose fitting. now what i did was take my pan and the fitting to an exhaust shop and had them drill a hole and weld it in.



on a side not do NOT use anything under 3/4 inch for the return line because you will restrict oil flow
tired of typing more to come tomorrow

im also not being rude i started with the check valves back in 2005 when there wasnt alot of info or guys on here that knew a lot about turbos but doing it yourself is a good way to learn but has its draw backs IE blow motor kinda stuff
