Just some advice for you. I have spent many hours on a dyno doing R&D on intake systems. First of all.... Do not use 3" piping on the car... Very bad idea and you COULD throw a CEL or even worse damage the MAF itself. Weapon R and AEM wont use pipes bigger then 2.5" on these motors cause of that. Make sure that MAF is sealed 100% or you will have air leaks which will result in unmetered air and your car could run lean at High RPMs. As far as using 93 octane, definitely no need and you shouldnt be seeing any improvement at all. In fact the damage it is doing to the internals of your car could be worse then the HP you think you have gained.... Your spark plugs from the factory are not rated for the 93 octane and without boost, I am sure you are just helping clog your cats before their time :) Not knocking you just offering advice before your final design!

I havent had a whole lot of experience building intakes but hope maybe you could clarify that and answer a couple of questions.

Is 3" considered a faux-pas because the throttle body bore dia. or actual flow characteristics? Doesnt the 3" just imply the flow could be increased dramatically over stock?

If 3" is bad what about guys who just bolt a cone filter straight to the throttle body?

Obviously if everything has been made in 2.5" dia thats whats been dyno'd but has anyone even tried to dyno a 3"?

The whole intake setup actually seems really similar to the old TPI setup on the old LS1. (Long runner intake ater throttle body, little to none before).

The gas definitely made a difference, im not sure if it was bad gas before, or what... but it definitely made a difference :). If not these plugs, what plugs would I use for 93? Would there possibly be an increase in mileage?

The MAF is sealed as far as I can tell, and yea, it has/is throwing a CEL :)

What other options do I have here? I dont know where to get 2.5" PVC, I see 2.5" metal piping, but I have no way of working with it.

It looks like this kit may fit: http://cgi.ebay.com/ebaymotors/TOYOT...mZ220054255738

Its not loading for me now, but from the smaller pic it looks like it would bolt right in?

spkrman · 12-03-2006, 04:54 AM

you guys think that might fit? Looks like the filter comes back up when it should stay straight, other than that I think it would work great.

Could also just wait on ebay for the piping, shouldnt be TOO long until its out? :)

Be carefull with any intake with the hose before the MAF sensor... read up/search over on the Scion boards as to why exactly.. but it was talked about at length.

Otherwise, looks like a better fit then most xa/xb short rams would...

spkrman · 12-03-2006, 07:40 PM

the hose is after the MAF there, correct?

No, its not.

Stock throttle body > EGR Hose > MAF sensor > Filter.... is how the eBay intake is..

vodkalush · 12-03-2006, 08:07 PM

deal with my n00bness in that matter; but what is an EGR hose?

johnnyfive · 12-03-2006, 08:10 PM

EGR = exhaust gas reciculation

well, teh flow of air is the other way....

But either way, the EGR hoseshould be on the OTHER side of the MAF, NOT like the ebay intake, correct?

Is stock not the same exact setup?

Correct.. duh on my part.

You want the EGR tube between the MAF and Filter, acording to what Ive read from the Scion fellas..

Clear enough now?

vodkalush · 12-04-2006, 11:33 AM

so, if I decide to go ahead and attempt make an intake, would it be wise of me to put/make a egr tube? or will it not really make a difference?

"Most" do that I've seen for our engine in the Scion... K&N's intake however does not, and that was talked about.

Dont know why, or what effects it has, Im just going off of everything Ive read, and passing the info along.

Thursday, FedEx will be here with a little something (intake), ill report back with my review.
