Converting IDF/DRLA to throttle body Options

[cgnj]

I have always wanted to do ITB FI for my 2270. I found a box in my stash of parts with a DRLA 45 with one of the air bypass screws stripped. I found this thread on STFSTF IDF/DRLA to throttle body.. I guess I would have to block off everything above the throttle plate, and machine my manifolds to for injectors. Feedback on this idea is appreciated

I HOPE they don't use stock Miata throttle bodies...

I have 4 Miatas, two MSMs. and NB1 and a NB2.

The stock throttle body has a known failure point.

The shaft is too thin, it cracks with high vibration and drops the butterfly screws into the engine.

TARGET DOWN!

The "fix" is a "Skunk II" T-body that need a bunch of mods before it can work. Hogging out the IAC passages is one of the mods. Too wimpy throttle return spring is another.
They are commonly referred to as "Junk II"...

IACs and ITBs together has never worked worth a shit for me.
Making the "plenum" so the IAC can feed all cylinders NEVER works like you think it will.

In the case of a T4 with digital FI I believe I could make warm up smoother via a bit higher RPM idle setting and computer control of ignition timing. Adding 5-8 degrees IS worth 2-300 RPM on most vehicles...

I live in a climate that does not get stupid cold. This might be more important at 20 below.

Now something with a single throttle body and plenum is SET UP for IAC.

Only issue I have with an IAC now is the cost of a Bosch Motorsports ETB...

Here's a 60mm one. Included in it is a T-body, TPS, and idle air control.

If I was setting up a "new" plenum system this is what I'd use over ANYTHING...
Gets rid of so much crap and only adds a bit of wiring and a throttle sensor/pedal assembly.

Another member on this site posted about 2005ish Acura TSX throttle sensors. They are remote to the pedal and operate via a throttle cable.

Don't know if they will work but it's worth investigating...
