ReadMe: Important Information and Updates

Updates: Because this information is spread across numerous pages, I will post any significant updates below. Please check this page as often as you feel necessary.

What's New: Latest Updates to the Turbo EFI Pages

2-22-04 Took down Turbo Forum.  Updated some bad links. The EFI controller highlighted in this text is no longer being made. In the future, this info will be re-written to reflect the current EFI computers.
8-28-02 Added EFI Installation Diary which shows how I built my intake
5-16-02 Updated Parts page with pictures. Started installation diary.
5-6-02 Minor Updates to Turbo page and Fuel page, added some links on Carb page
4-12-02 Minor updates to Turbo Page
2-15-02 Updated info on Fuel Pressure Regulators
2DO Sections 2 DO:

Disclaimer &  WARNING:  This information is designed and intended for off-road use only. Depending on the laws in your area you may only be able to alter your vehicle if it is used only on a race track. It is up to you to check the laws in your own area.

By following this information you are going to ask your engine to put out more horsepower. As soon as it does, you take away from how long it will last. How much horsepower depends on how far you think you can stretch the rubber band before it breaks.

Remember anything and everything you do is at your own risk. Please be careful and follow proper safety precautions.

General: Much of this information in these pages is directed at installing a fuel injection and a turbo charger. The information is somewhat "generic" and should have some usefulness no matter what your plans. The fuel injection will work wonderfully on the vehicle without the turbo charger and driving the vehicle prior to installing the turbo is a recommended step. This will allow you to get a feel for your "new" motor and allow you to learn how to tune the FI system.

Once you feel comfortable with the FI on your vehicle, then start modifying your exhaust for the Turbo. Turbos and FI  are both included here because the turbo is an inexpensive addition and will give a tremendous performance boost to the existing FI system. Furthermore, the turbo can be run with a regular carburetor. I personally chose not to follow this route for reasons that will become apparent when you read the other pages. If you choose to follow the carburetor route, some of the information here will still be very helpful to you. I will post more information for carbureted-turbo engines as I receive it and as time allows. 

Construction Requirements: This information is designed for someone who has mechanical and fabrication experience. This is not a strictly bolt-on modification. You will be required to choose, find, and test the necessary parts. You will have to buy, construct,  or modify an intake and exhaust manifold; wire the computer to the vehicle and the injectors; run the proper fuel lines; and run oil lines for the turbo. As you progress through the various steps, feel free to ask questions in the TurboTech forum or in BuggyTalk. If you don't have the required experience or tools necessary I suggest you find someone who can help you.

Credits: This information was compiled, organized and edited with the help of several people. Most notably, Tim Van Setten of Tim Systems provided the vast majority of the technical information. Tom, Paul and Dadeeo, who are regulars in the BuggyTalk forum provided much needed feedback as the pages were written, edited, rewritten, and further changed. Thank-you guys.

Common Definitions:
EFI = Electronic Fuel Injection
PSI  =  Pounds per Square Inch - used to measure pressure
MAP = Manifold Air Pressure - A MAP sensor is usually used in turbo applications
TPS = Throttle Position Sensor - detects how far you have the throttle open
TPI =  Tuned Port Injection - injectors spray at valve on equal length intake runners
TBI = Throttle Body Injection - larger injectors spray into central manifold plenum
AV Gas = Aviation Fuel - available at local airstrip.
Butterfly = Air Valve connected to throttle cable - used to regulate air flow into engine
