theres more space in the spot where the old intake used to go , so more air inside the engine bay and more air to get sucked in by your intake.

Im really not trying to rain on your parade here but you should be aware of at least one thing...moving the air filter inboard of the radiator/fan like that will actually cause the intake to suck warm air...and as you probably know warm air is less dense than cold air. Therefore while in theory you might be getting more air flow you are actually getting less air density, thus less horsepower.

if you do a little research into intake set ups you will find that more people prefer the approach of getting cleaner colder air from outside the engine bay.

What I did for my setup is I used a conical filter that had an open top. I then fabricated some ducting that goes through the front (where the stock air cleaner originally got its air) and then using ducts from various cars (the most important one being the fresh air duct from an 89 ford F-250) I found in the junkyard, created a sort of a ram air scoop out front to catch more air at speed.

In summary, while your setup might look nice and all, dont expect it to noticably increase performance

i know that too thats why i jus ran and got sum felxible tubing and it connects to the filter, and the other end i could jus put by the front bumper with a scoop so like you said i can catch more air. thats what i did with my cadillac b4, i know that theres not a really noticable diffrence in performance, but gimme a break, dont you feel better, when you do sumthing diffrent with your car?

but do you think this setup right now with the duct, which one do you think is more beneficial for me? the first one that i got with the afm in the end by the filter or the one that i got right now?

i love forums, without this i would have never had critique from people like u

Well, I dont know enough about the airflow charactoristics inside that ducting to know if the AFM is better closer or farther from the Throttle body, or if it makes any difference at all.

Having the cold air duct go all the way to the front wall is a good start, but I just wonder why do that and not just leave the AFM in its stock position since it kinda defeats the purpose of what you did in the first place. If you like how it looks in your engine compartment where you have it, I'd say leave it and make it look nice and clean by not going to the front wall with more ducting.

Yes, I do love doing something different with my car...its why most of us buy these cars and spend any time on them in first place. Sure I could go out and buy a mk4 or something else with more power than my N/A Supra, but what fun is that? I would be bored in a week!

The last car I had was a 73 Celica converted to a Hybrid 20/22R and there wasnt a whole lot stock left on the car. I owned it for 14 years. If youre like me, any little thing you do that makes the car uniquely yours is worth doing.
