Pod Filters Are Bad For Altezzas, 3S-GE power loss and irratic A:F ratio

I don't listen to the radio so that doesn't bother me, just that I lose the settings on my headunit like ricey personallised flashing colours hahah

what will happen if i install intake without reset my ECU?

your engine will feel like shit haha

It'll learn eventually, it'll just take longer. Resetting the ECU gives a baseline for it to learn from is all...

There 3 methods that I know of posted here and on LOC

• Disconnect the battery
• Pull the ECU, EFI and ETCS fuses
• Pull the EFI and ETCS fuses

The first 2 will reset the clock and lose the radio presets the last one will not.

On the ETCS fuse for the 1G-FE, my IS200 has one so would assume that the AS200 should have one as well

Okay well I've had some interesting results.

Going from having the an afm mounted in a pipe, and then having an adaptor plate with the pod filter on the end, to doing the equivilent of 'port matching' the pod filter to the end of the pipe (having the pipe end the same diameter as the pod filter opening) has mad a HUGE difference! Obviously the air is far less turbulent, as now it runs like a dream! even at very low throttle positions, which is where it was previously a problem.

The only downside, is that now my pod filter has gone from being completely rowdy, to almost silent! haha.

so does make a fair difference? is yours a altezza rs200 with the BEAMS engine or the is200 1gfe?

I've got an MR2 with a beams 3SGE engine, which is virtually identical to the Altezza 3SGE engine.

I cant say if it's made a difference, as I never had the original airbox to start with!

I've also got a 1983 Carina coupe with a beams 3SGE, altezza 6 speed, altezza LSD, etc. (work in progress, haha)

Got a photo for us please Roman??

Sure.

Here's the MR2 engine:


Here's the Carina.

Lol! Where's the pod setup on the MR2??

I wanted to see the inlet pipe length and diameter..

Blitznur is going to need it here-

Lol! Good question, haha!

Okay this is what my pipe looked like before, and it ran like crap with this:

The hole on the pod filter was way smaller than the diameter of the pipe, so I think this caused a fair bit of turbulence... as when I cut the pipe down a bit, and mounted the filter so the pod filter hole was the same size as the pipe diameter, it ran great! my car still idles high, but I'm not entirely convinced that this is caused by the pod filter setup... I think that my ECU is thinking that my aircon is on, and the engine is under extra load, and this is causing the revs to increase.... Or it could very well be thanks to the pod filter setup. Or the flywheel being so much lighter than standard perhaps.
I've got a standard airbox on the way, so I'll be able to make some definitive comparisons some time soon hopefully! I will keep you posted.

If I was wanting to make a pod filter setup, I'd try to ensure that the pipe diameter is as close to the factory diameter piping as possible. And also ensure that the air coming towards the air flow meter has as little turbulence as possible, a basic modification to mine has made all of the difference! but this can be tricky, and can take some trial and error.

Personally I think that unless you've done a fair few other mods, a pod filter setup is a waste of time on the altezza, you're more likely to get it wrong than get it right IMO. Seeing as how the MAF sensor is so picky.
I would have the factory airbox in there to start with, if I had one.... it just so happened that my engine came with a pod setup.
Also 'off the shelf' pod filter kits designed for altezza would more than likely work out cheaper than getting one fabricated, unless you can do the work yourself. And you know its going to work, if its from a reputable company...

Thanks Roman, that's all sound advice.

Ar rai wa hi!!

I was wondering, do you have a is200 or as200? and does ur apexi intake fit on the is200 engine?

OK been a while since I was on here and I was asked to post back on my experiences.

I found that my Apexi pod filter gave stuttering at low revs when I put the "foot down".

The set up I had was pod filter, RS-R equal length manifold with 2-1 down pipe taking out the cats.

Fitted a Camcon and went for the recommended advance on the valve timing and it all went to shit. Floor it at a junction and it just died big time instead of a hesitation every now and again.

Felt like "bogging down" through being too rich so leaned it out a bit at low revs and it got worse! So went the other way and made the mixture richer and hey it was sorted out.

So to sum up, the aim of the pod filter is to increase air flow, the MAF sensor measures the SPEED of the air and the temp. If you open up the inlet tract by increasing the diameter there is a bigger mass of air flowing for a given air speed so it will be running lean. A bit like putting bigger carbs on and not upping the jet sizes.

Nearly bought a AFR meter to have a look at what was happening but never got round to it, you can't drive and watch it at the same time after all.

i got RS200z

I am after a stock rs200 Airbox, prefer in Aus, but NZ may be ok.

Are any of you guys with pods willing to part with yours.

I think the RS200 box will ine up best with my single turbo 2jzgte, i need to look a little more stock under the bonnet and reduce inlet noise ( big turbo - no BOV).

Thanks

PM if you can help!

the Pod filter in my car with the standard ECU sucked balls,
Airbox was alot better midrange torque.

Go for Pod if you get a tunable ECU, you'll be able to tune out the flat spots etc.

Here is a pic of my Cold Air Box at the mo, still got to put a back on it once i get my Catch Can made up and installed.

Enjoy!

the RS200 Airbox IMO would be too restrictive for that amount of power, unless you do some sizeable modifications to it.
No BOV would actually be louder than having a plumb back system also, it'll compressor surge which sounds cool, but is really loud

Cheers, Mike

Hi, My main motivation for wanting a factory airbox is that I want to make my engine bay look more factory. I will make significant modifications to it to make sure it is not a restriction, maybe even modify it to conceal a pod inside.

I do need to consider a plumb back bov, as the impeller reversion noise is VERY loud, and quite a give away.

Still looking for a rs200 airbox. or even just a rs200 in sydney that i can look at to see if it will do the job?

Matt

One in Orange....

Too busy until mid-Dec working on rental house & moving into our new place to make it down to Sydney myself.

RSMIKE can you put more photo of your engine bay?i wanna see how you set up the catch can
