You have not read the post.

You must read!!!

Here is an extract out of that document.

4) Gauge setup. You can get a number of gauges from Autometer or from some other manufacture.

You will need an Air/Fuel ratio,

Refer to manufacture for setting up of there gauges

5) What we do from here now is to tune the car. This will show you how lame stock can be.

6) In this tuning, we will select a nice turbo exhaust using a custom 2.5” – 3.0” piping. Also get a good air filter from companies like K&N, Ractive and so on.

7) Install a good Adjustable fuel pressure regulator w/ a gauge (optional but need to see what your fuel pressure is set at and to see if you fuel system can handle the high fuel flow need after turbocharging.)

You will be using the A-FPR to supply more fuel to the injectors, there reducing the duty cycle on the injector when you need more fuel to make more power and have a proper fuel-air mixture after turbocharging.

8) Install some nice Platinum, Iridium or any racing plugs from manufacture like NGK, Nippon, etc.


9) Start the car and check you A/F gauge. Increase the fuel pressure using the FPR. Make a note on the reading display by the fuel gauge meter. Listen to how the car is idling. We do not want the car to sound lumpy, as this is wasting fuel. Check the Autometer or the A/F meter for how rich or lean the car is.

Test drive the car and the your keep eye on the A/F meter. Keep from using full throttle opening since the meter will not read properly. We want the reading to be in the range stoichiometric range (yellow lights into green) or just a little rich (into few green lights).

Must read http://www.autometer.com/hp/index.html

Check for the best time it take to reach 100km/h or some measurement to see what your best A/F would be for your driving style.

10) After running the previous test, let us now advance the timing. You will need a timing light. Read through your Celica Repair or Workshop manual (by this time you should have one. You will need it later) on how to do this. (You will have the turn the distributor clockwise after slacking it off)

Adjust you timing by every 2 degree. Listen for pinging (sound like little hammers hitting on a piece of block metal)

Tests drive the car again and listen for the pinging sound under normal and hard acceleration. When successful, push the timing up again (by 2 degree). Run the same test again. If you start to here the pinging sound (for Air Flow meter people) adjust your AFM a/f screw. Otherwise, increase you fuel press until you get rid of the sound.

Please remember that you must meet a balance between A/F and timing.

Test drive one last time to make sure everything is good.

Your car should now feel very fast and capable.

You can also use the Btilz Power Meter i-D http://www.blitz-na.com/PM_ID.htm OR the G-TECH/Pro Competition http://www.gtechpro.com Monitoring tool.
