Hmm, would using the 4th gen ECU be an option or would that be such a nightmare it wouldn't be worth it?

I believe most of them are auto
which isn't as bad, but it could mess with timing and crap like the auto ECU does on the 1mz swaps

Right now with the 3rd gen ecu, I only need to contend with two rogue sensors. Would be a pretty big game changer to run the 4th gen. My buddy mat has a 4th gen swap on his 5 speed becoming a fairly common swap despite the weakness of the dainty rods.
Ahh that's right, Caldina. I like my idea, turn the IACV into an electrically controlled manual choke and call it a day.

Alright guys....here's the scoop.
I've posted on Facebook complaining about the issue I was having, where the vehicle would start and idle fine and then begin to run ridiculously lean....
I've since fixed this. In the process of diagnosing I re-installed my 3rd gen manifold etc....
After reinstalling the factory manifold I still had the same problem, which led me to ordering a new fuel pump sock (it was blackened), and the car would barely run on the old gas in the tank, which I have replaced with fresh gas.
Turns out none of these things were my problem at all, but I've also decided not to put the 4th gen manifold back on, and to just run the 3rd gen manifold. Meaning I was successfully able to adapt the 4th gen manifold. These are my reasons for leaving the factory manifold.
4th gen ISCV DOES NOT ADAPT. Don't bother trying, you will get crazy symptoms. If you have a stand alone that can convert to pulse width modulation be my guest.
4th gen TPS will work, but you have to reverse the pinouts for VC AND E2!
My TRD 3 point bar will not fit with the 4th gen manifold.
You have to make a custom throttle cable bracket on the 4th gen (which I did).
The 4th gen doesn't play well with the 3rd gen fuel rail, you have to clock the fuel pressure regulator, and make a new return line.
Since the IACV goes bonkers, you will have terrible idle quality, and be forced to hit the gas and brakes at the same time in many cases to keep the car from shutting off, which could be a potential safety risk.
So I'm putting my tail between my legs, and have reverted to the 3rd gen manifold feeling both successful, and aggravated.
Here's some pictures.
Here is one dirty fuel pump sock.
Here is a picture of the hot side pipe...if you weren't aware already...that's my Dad.
Here is a picture of the hot side pipe installed.
Here you can see the turbo clocked down where it connects to the hot pipe.
Here is a picture where the pipe hangs down slightly.

It was nice of that badass sea captain to lend you a hand. I don't think there's any shame in going back to the third gen manifold, you found the issues of trying to use the fourth gen and got it to work for the most part. Plus this way it'll be quicker getting it back onto the road, so I say you made the right choice.

OOOooooo...a Treadstone IC. How's the quality on that bad boy? Which one did you get?

Lol! Every build needs a badass sea captain!

Haha! Yup it's a treadstone! I see them as a kind of up and coming company that is reasonably priced now, but will experience a price spike once popularity increases. Great price, hand welded, and good quality. It's a heavy sucker. Its 4 inches wide, but I don't remember which model it is.

Bery nice! I'm considering getting one for the Poopra since they're anywhere from $300-$400 for a core and piece together the rest of my IC kit, or just wait til Black Friday later this year for ETS to have their sale and top it off with my friend's military discount. lol

Great 4gen mani, IAC, and TPS info on a 3rd gen.
Piping looks awesome !

Thanks Dustin!
Another quick update. Today I hooked up the waste gate, fab'd up my turbo intake, fixed my fan wiring issue (i'm not running A/C), installed the passenger side fender, re-located the line for my catch can, and re-installed my fuel line. Here's some pic's and a video.

A car without A/C is useless above 70º though. 
I'd be the one person using their A/C on a track day, I don't need those few extra tenths of a second that bad.

Wish me luck guys! Later today I should officially be able to drive the GreenBullett!!!
Huzzah!
2001 Miata LS 5-speed
Well guys I drove it...it is terrifying...
So it just sits and spins the wheels and refuses to turn once it finally does grab traction?

Much better than you might think! The turbo lag actually does me a favor, and keeps it planted for longer.
FYI: The screamer pipe is absolutely the most hilarious thing on this entire build! It scares the ever-living **** out of people!!!
I've got the boost turned to about 16psi at the moment, and once it builds up it takes off like a freaking rocket!

Try and stay out of trouble.
One of these days I will have a car with forced induction, not really for the power but more for the added sounds. There's someone nearby that has a '66 Chevelle running a supercharger with a BOV and it sounds magical.

dude i love how you routed the piping.
FYI 1ZZ and 2ZZ use the same TPS plug, but the wiring is backwards.
Its interesting about the PWM of the newer IAC's. Ill assume that the 3rd gen IAC will not bolt onto the 4th gen throttle body. im sure there is a PWM dial that you could route in the car and turn it, much like earlier mentioned choke.
what about having the 3rd gen throttle body altered or adapted to match the 4th gen IM. but then again i see you had other issues with it.
ill be happy to take that off your hands for you

My friend and I tossed around the idea of creating a switch to send a PWM signal. I'm pretty sure the specs are available in the 4th gen manual. I used a 1zz TPS plug. only wires that need switch are VC and E2. VTA is already in the right location. Unfortunately altering the throttle body isn't really an option. If you had access to a CNC machine you could make an adapter plate for the 3rd gen throttle body, and just cut the bracket off for the 4th gen and weld it on.

Hey guy's quick question! May be worth of making a video.
Car starts and idles find on cold idle with VAC around -15, but after it warms up it drops down to between -12-9 and idles rough, and will occasionally die at stop lights. Any insight?

Has the ECU been tuned in for the cams yet? The more lift and duration the lower the vacuum will be. May just be as simple as raising the idle speed and changing the idle mixture some.
