PART 1
How to install a nitrous wet kit on your mr2 turbo.
First off what you do to your car is your business and this write up does not guarantee your car will not blow up from increasing power levels above stock. No warranty is written expressed or implied!
Now that said, I used nitrous works wet kit part number 13092, it is for a supra non-turbo, but works fine in my application. I am not going to go word for word out of the instructions but rather helpful information that apply to installing it into your mr2 turbo. First find a warm dry place to install the kit, like this:

Read the entire directions front to back before starting this project. And next find a place to mount the bottle, I used the rear trunk. You may mount the bottle in the front trunk, or inside the cab just make yourself aware current NHRA rules, such as a blow down tube will be required if the bottle is in the drivers compartment. The 10 pound bottle will only fit one way in the rear trunk so pay close attention to the pick up tube when installing. Note you will gain more power having the bottle run the length of the car versus sideways, and it will allow you to use more nitrous before refilling. I mounted mine like this:

Make sure not to run the nitrous feed line next to the hot exhaust and moving parts. Use the rubber grommet in the side of the trunk to exit the feed line. Now into the engine bay find a place to mount the solenoids, I used the extra hole in the bracket on the air fuel meter. Measure the nitrous and fuel line before installing the solenoids too far from the fogger. When installing the fogger it should be 6 inches away from the throttle body which puts us at the oem rubber right before the throttle body, bad idea it will rip and cause boost leaks, loss of power, and funny running conditions. If you have the means make something like this:

If not drill and tap the OEM throttle body inlet. So the bottle is mounted, feed line is ran, solenoids are installed, and you to made a custom fogger adapter piece, so what?s next lets cover the micro switch often called a full throttle switch. It needs to be mounted on the throttle body in line of the throttle cam like this:

I also used it to ground the solenoids. The last thing is solenoid electrical and we will come back to this. You will have to choose a method of activating the system and I picked the b&m shift knob with a momentary switch, but you may pick any other type of normally open switch.

Just some food for thought a relay is a electromagnetic switch that uses a small amount of voltage to control a large amount of voltage. So do not tap a wire into the fuse box. Run all new wires following the book exactly, don?t skimp on electrical connections always solder and shrink-wrap. No twist and tape. I mounted my relay inside the cab behind the passenger seatbelt cover; only one hot wire should be going into the engine bay for the solenoids. After the wiring is complete perform a dry test by arming the system and rotating the throttle cam to the full throttle position you should be able to hear and feel the solenoids click. If your fuel is already hooked up you cam still do a test fire just shoot it into a can or something to catch the fuel.

PART 2
Fuel needs
You are going to need to buy this:

http://www.mr2ownersclub.com/nitrousfaq/images/nitfaq025_jpg.jpg
to get this:
http://www.mr2ownersclub.com/nitrousfaq/images/nitfaq010_jpg.jpg
Its a banjo bolt that replaces the oem one on the fuel filter but adds a 1/8 npt port on top. Just perfect for running a line to the fuel solenoid like this:
http://www.mr2ownersclub.com/nitrousfaq/images/nitfaq011_jpg.jpg
Its ultra clean and oem looking, plus there is no cutting into the fuel lines.
