Fuel Injection/Turbo questions.

Alright I have a few major questions that are chewing my mind apart. I used the search button and searched for my anwseres but I had no luck so I am hoping that my Fellow Mazda lovers can help me!!

I have a 2.2 carb engine now, I want to switch to a F.I. Turbo. I know I need the Heads, intake, exhaust manifold and ECM from a turbo motor.

I got the imprssion that if I switch over to a 12valve head I need to go Distributorless. Is this true?

Also when switch over to new F.I. parts will I have toi add any new sensor to the block?

Also I heard somewheres that the ECM wiring harness will have the wires already labeled. is this right?

What do I have to do about fuel dilivery, can I just put a high flow inline pump and a pressure regulator or do I have to switch out the Carb sending unit for F.I. sending unit.

Do i have to make a custom throttle linkage?

and lastly what type of intake is best? the one where you have to cut and re-weld it or the one that has the throttle busy in middle of manifold?


I appreciate any help!!

Bump

I posted a thread on this.
Unfortunately, it is still hanging in the air right now.
I just don't have the motivation yet to finish it up.
The only part I need is the external E2000 ford ranger fuel pump.

If you go with stock parts, no need for a sensor in the flywheel.
Injectors are batch fired in two stages (1-3 and 4-2) via the stock ECU and timing is off the dizzy tach output.
If you go with stacd alone systems like Megasquirt, then you need a triggering device for the ignition and fuel injectors.

I found a complete intake manifold, fuel press regulator, ECU and some harness from a 1989 turbo 626 without the turbo.
The throttle body was in the middle so no need to relocate the TB.

Of course you have to fab the cable mount and linkage which is normal when retrofitting.

Good luck.

What is a stand alone system?

And you are sayin that using your factory distibutor dosn't work very good when you switchg over?

This might help with some questions:

This si saying the distributor will mess with the firewall, but on my truck the distributor is in the front of the engine? So how will that affect this all?

Because they did a full engine swap with the distributor in the back.
If you are using your original B2200 engine and just adapting the FI stuff, you can use your original distributor tach output for the injector trigger.
The stock ECU uses this signal.

AHHH the blocks are the same so why would they switch them? And the stock distributor will be good enough or should I swap over the donor cards distributor also?

I used MegaSquirt and Ford EDIS, I had an adapter machined to hold te crank trigger wheel to the Mazda crank pulley. If you dont want to cut your firewall for the 626/probe distributor. Mine is still N/A but it runs much better on fuel injection.

For the fuel pump, I used the stock in tank pump and sender from a B2600i and upgrade the lines to high pressure. Just plopped in the tank like factory. I have looked at an RX7 intank pump and sender from a 90 GTU, and it looks to be the exact same part, but I have not measured the length to be certain.
