Wow I know this is old but I'm so impressed, I can't wait to do this and also paint the engine head like you did xD
the 72 TB in the galant is it the same TB out of a 91-93 n/a 3kGT?
nvm looking like the 3kgt is around 70mm, found one sized at 75mm. anyways does anyone know if these are usable on the 4cyl, and what would be needed? I would guess it would be about the same work as installing the 74 TB

Why did you bump a thread just to say that?
Sorry for bringing back such an old thread, but did anyone who has done this swap ever got a P0507 code? Everything seemed to be running normal when i installed it, after my car warms up it idles at ~800RPM on gear and ~1000RPM while on park. Then a week later since the swap, this code pops up.
Here's the definition of the code P0507:
Idle control system RPM higher than expected
Probable cause
1. Large vacuum leak on engine
2. Throttle body condition - Dirty(i'm pretty sure it can't be this since i cleaned the throttle body before installing it with CRC Throttle Body Cleaner and removed the IAC motor and TPS before doing so)
3. Faulty IAC valve/Throttle Body (Kind of thinking this could be causing this issue, since i got my throttle body assembly from a junkyard)
Thanks in advance! hopefully i could get some help on this
Are you sure you put the gasket is on correctly? When I put the 6g72 TB on my Eclipse I had a bad vac leak and I could hear it, I had to flip the gasket 180 degrees and the leak and noise went away.
15 F150 3.5 ecoboost 4x4 - daily driver
01 Galant ES V6 MT (sold)
00 Eclipse RS MT
I'm pretty sure i did that because, the holes only matched up with the bolts when i had the gasket flipped, as you said, 180°. But i'll check again tomorrow
I didn't find any vacuum leaks, but could using the i4 Throttle Position Sensor cause this issue? help please
Just read that the TPS for th i4 and v6 are the same. What else could cause the code PO507?

You should use the IAC from the v6 and are you sure the TPS is the same for 4cyl and v6? When I swapped, I had a similar code (it looks familiar, but I didn't write it down), but it was because the gasket was the wrong way on. I later on swapped it with a v6 gasket anyway.
I do have the V6 IAC installed and used a V6 gasket and yeah, i re-read this whole post and someone said that the V6 and I4 TPS had the same part number. Which way exactly is the right way to install the gasket? I just adjusted my TPS and cleared the code for now, but if the code comes back(hopefully it doesn't) i'll take a pic of how i installed the gasket
One:
You need evoscan to see where your tps % is at. It should be around 12.5-13.3%. Any higher idle will go up and pcm will thinks is not idling.
Two. Do a leak test around the tb. Some times gasket could be install wrong.
3. Pcm needs to re-learn iac trims. You need to reset pcm "disconnect batt for 5 min with headlight ON to reset fuel trims. Let it idle for 30 min no rev, take it for a nice drive 30 min or so. And rev then let go of the gas so iac could adjust it self
coconut, did you get your throttle body from a junk yard? or did you pull it from a working galant?
tamim13, did the code P0507 ever come up for you? and how long after your first install of the throttle body did you decide to check if the gasket lined up correctly? because for me i was code for about a week after the swap and everything was running fine i think
For everyone that did this swap, could you share how much you are idling if it changed at all? I don't remember how much i was idling on park and on gear before but now i'm at about 1000RPM on park and about 800RPM on gear after warming up the engine. Does this sound right? or is it too high like the code says? This is really bothering because my car is due for another inspection soon. Thanks everyone for the help so far, hopefully i would be able to solve this issue without having to go back to the i4 throttle body.
Got mine fron the J/Y and it came off a v6 galant.i cleaned mine before i installed it, new gasket installed also for the v6 not for i4.Mine did idle high,made some minor adjustment with the idle screw.Idled at 800rpm in drive with the auto trans but im manual swapped now and its at 800rpm.Did you make sure the vacuum lines on top of the throttle body are in the right spot?Dont know if that would make a diffrence but just throwing it out there.
I don't remember the code that I got, but the idle was not too fast, it was stumbling a lot, like the engine was about to die, that's how we figured it was a leak. It was right after the install and first time I started it up. After correcting the gasket, and starting up cold, my RPM would be about 1.5K and then drop to about 1K - 900. After driving around it would come down to about 750-800. I had to adjust the idle screw all the way down to the minimum. Also had to disconnect the battery for the whole process of swapping the TB, so the system does have to relearn the idle. I also changed the coolant lines to the v6 ones, the i4 does not fit on the new TB.
I've been code free for the past week, thanks for the help guys! All I did was adjist the BISS Screw so that my idle on park was between 800-900RPM and the code just went away. Didn't need to clear it or reset my ecu. Just updating for future reference, thanks again!
I know this is kind of old, but, I'm in the process of doing this retrofit, (Outlander Manifold with Galant V6 throttle on a I4) and want to gather all the important info; So, my question: disconnect the battery with the lights "ON"? Also, is there an easy way to adjust the TPS? Thanks for your replies.
