Converting to 7mgte electronics

[935motorsports]

I couldn't find a 7mge harness to save my life. Since I had ALL the turbo parts for a 7mgte swap, I figured why not. Myself and others have been curious about how the 7mge would perform on turbo electroincs.

I put the turbo injectors in, since it will get turbo at some point.

I paid about $200 for all the 7mgte electronics, turbo and turbo manifold. For now I will be running an SAFC, 2.5" header back, the intake pipe, and advanced timing with 91 gas. We will see how it performs. I'll log the wideband when it's all done to see how the AFs are.

i wouldnt advance the timming, i would leave it @stock.

just my .02

i would also think you might be getting a touch to much fuel.

I'm pretty sure Borhor had the Turbo injectors in his NA for awhile and they were making his car run rich. I dont think he had the turbo electronics in though.

I have always wondered how my 7mgte would run if I took the turbo off and ran a 7mge ext manifold.

I would only want to do this if I had to though

I'm interested in how this thing runs, should be interesting.

Wicked fast, like a mid '80 Honda!

Lower compression ration, mild timing advance curve, no ACIS, AND no boost.... ick.

My dad had a 82 corolla wagon that did 0-60 in like infinity...man those where the days.........

It is going to read air input and inject accordingly. It is only going to read a small amount of airflow vs turbo. So, it SHOULD act just like a turbo car would pre-boost. The main question is what is the ECU going to think at say 5800 RPM with such a low air flow reading. Will it have proper mapping or just do a full rich dump and cause soggy performance.

However, we are all guessing at this point. We will find out soon and put the rumors to rest hopefully.

Like I said, I have an SAFC II to pull back as needed. I was going to try it with 7mge injectors, but I figured I should just save time and do it now.

So when it is ready, all I have to do is add the turbo and ic parts for the rest of the fun.

Damn, wish I'd known you were looking for a harness, I have one in my parts car. It's missing the tps connector, but everything else is there. Have injectors, ecu, and dist. too... Drop me a pm if you want anything, and maybe we can work something out.

cuel what you want 4 the harness? pre 89?

 

[935motorsports]

I could use the harness, but it has to be a 89+ gray plug harness.

It's up and running!

Found some 7mgte plug wires and got everything plugged in.

It cranked right up and revs nicely.

I went for a test drive and it pulls like it should.

It is not driving horrible or "pig rich" as most had thought. It feels like a typical turbo pre-boost.


No wideband yet, so no real results. But it works great so far. Next step is set timing and install the SAFC so I can see what the max reading is, compared to say a 2JZGE.

Awesome great job!

935: Oh, sorry, 86.5

no videos yet, sprung an oil leak...

I'll have to fix that first.
