Beams Throttle Body to Rev 3 Options

[Kiolofunk]

What's up 6GC?! I'm Kiolo and I'm from the Philippines.

I recently swapped over a 3sge rev 3 motor into my AE101 with celica brakes, not that anyone's interested.

As the title suggests, I'm looking into swapping over a 3sge beams throttle body into my 3sge rev 3. Reason is my iacv went bad and i found a beams tb from a local yard with an iacv on it. Unfortunately, they won't sell the iacv alone so i went in and made the purchase.

I've tried bolting it up and it seems right on, however, i was wondering what would be the effects of the larger inlet/outlet? I'm thinking that there really wouldn't be any power difference, possibly but not that much. Mileage consumption perhaps a little bit higher? Not really sure. Can someone enlighten me?

Thanks in advance!

if it bolts up and the TPS signal is good, then the larger TB will give you a slight increase of power. acceleration might be a little more responsive. thats about it.

And it will look cool

Bringing the thread back to life. I have only gotten to bolt this over the weekend and all seem fine except for two things:

1. One bolt doesn't line up. (I was thinking of doing a spacer adaptor) but comes problem 2 below
2. TPS plugs are different. Mine has 4 wires and the BEAMS unit has 3.

Problem has really worsen as my idle drops to 500 when idle and sometimes it's erratic (500-800rpm) but if i unplug the IACV sensor then it revs back to normal. Also, it makes a hissing sound when the idle drops and goes up. This hissing sound also isn't present when the IACV sensor is unplug.

Cleaning the valve doesn't seem to make much of a difference now. It seems that the valve doesn't really fully close/open which causes the problem.

I'll head over to the scrapyard next week and find another TB. Hope it's for the Rev 3 this time. If anyone needs the BEAMS TB with TPS and IACV let me know.

Has anyone else experienced this issue?

Can you move the IACV valve back and forth smoothly? It should move easily, if it's stiff or doesn't move then it's bad. It's a common problem for these to go bad either where they don't move smoothly or the electrical parts get weak and can't move the flap fast enough.

Thanks for your response. Yeah it moves freely although I'm not quite certain why it doesn't fully close, like it leaves a gap. Not sure if that's how it's supposed to be. I tried one of my buddy's IAC sensor (from 4AGE) they look really identical so i gave it a shot and it is still the same. So I am leaning towards more on the mechanical valve itself. I'll post a vid up when i get a chance.

sounds like your TB cable is to long and its not opening the TB enough. I had the same issue with my 1mzfe TB on my 5s custom intake. so I made a bracket. should have painted it..

Good point though my cable is short. I actually wanted a longer one due to the cable hanging in the middle of the intake and it's being pressed by my strut bar (the plastic hose was cut open) so i had to remove my strut bar in the mean time. I don't think this is my problem though. Haven't gotten the time to post up a vid as I rarely use the car. Need you guys to see it to understand the problem I guess.
