Ok so what is the best thing to do for my 3sfe beside taking it out of the car. one thing id like to know is how to hook intake pipe to efi and by pass this thing any help or does it have to stay?
Hard to tell what you're pointing at.
Is that the AFM? If so, you cannot remove it without replacing it with something that measures air flow.
If thats just the filter, sure, you can remove it and replace it with a different, freer flowing air filter-like a K&N cone filter or the like.
Sorry it is the AFM and thanks for the response. In follow up is it it's self restrictive and would leaving it there affect the k&n set up and if so what would be a good after market brand to replace with is K&N the best choice to go with it's the only one I really hear anyone here bring up? Thanks again
K&N is just a popular (usually one of the best) conical air filters.
I've seen a fair amount of guys just replace the air box with a filter attached straight to the AFM, mainly on small port 4AGEs but the principle is the same.
^ Exactly. Just remove the air box, get the an adapter plate and clamp on the cone filter. You can also clean and reuse these type filters.
You will feel a better throttle response and it will sound better too. But don't expect any noticeable HP gains. By itself, MAYBE a couple of HP. But along with a good header and exhaust, 10-15 HP, depending on the state of your engine. Not a huge gain, but definately noticeable.
There are lots of filter choices out there. Most of them way over priced, claiming big HP gains and selling by name recognition.
I paid $40.00 for my 3" K&N cone filter 5 years ago, plus $3.00 or $4.00 for the adapter plate off Ebay.
Yeah, you'll be able to net a noticable gain, not huge, but noticable. Prices sound about right on the filters, we carry those in my store.
I'll be honest about my experience intake wise, it helped throttle response, but the big thing I noticed was just sound. Dont get me wrong, I thought it sounded great.... just was a good placebo effect.

it really is. After I put this K&N on, I could really hear my turbo spooling up.

Yes, the AFM is a restriction.
It has a flap in it and as the air flow increases, the flap is pushed more and more open by the stronger air flow. The position of this flap tells the ECU how much fuel to send. When you reach WOT, they open quite a bit and air flows freely enough for moderate engine mods.
If you remove it, the ECU will still be looking for that signal to know how much fuel to send, so some other type electronics have to be in place to do that. Like an AFC (Air/fuel Controller), Greddy Emanage, Hydra Nemisis, etc.
They're expensive and aren't neccessary until your horsepower modifications exceed the limits of the stock fuel system.
My K&N set up on my MR2.. I have a Stainless steel sheild over it to keep water off of it that may come thru the roof scoop.
I know it's not a Celica, but the principle is the same.
They're easy to install and will free up some space in your engine bay.
Thanks for the help and a few more ?'s if you don't mind I was checking on all this stuff after I posted and found these. http://www.amsoil.com/storefront/eaau.aspx?zo=1282443
I know or at least think I know lol that you get more life out of the oiled filters like the K&N but would a non oiled get more air flow? Also what would be a good type of or place to find a good header and exhaust set up. I not worried about smog testing I live next to a no test county so what ever is best for the 3sfe. Thanks again the throttle response is just what I'm looking for shes plenty fast for a good ticket with Georgia's new super speeder law extra $200 on top of any other fines.

Not neccessarily.
It really depends on the structure/mesh of the filter. Those look like good filters.
As for their life, I would imagine since their cleanable, they would be good for at least a few years.
Don't know about headers. Maybe Rob or someone else might know a source.
Do a web search. If I see anything, I will post it here.
The oil is just a filtering measure. On filters which require oiling, if you do not, it will not filter everything as well so more than likely the oiled filters probably flow marginally better.
As for a header: later 5sfes came with a header from the factory. Most of the time I see guys just buying them off of eBay though(brands like OBX). BUT! be careful, most dont mate up to the rest of the exhaust and eliminate the primary cat in the stock downpipe. Most exhausts end up being custom from a shop.
