Your car has an airbox. An airbox is where ever your filter goes.
Here´s my advice...dont pay for the chip. All it does is spoof your ECU into thinking the intake air is colder, therefore advancing the timing. What it doesn´t tell you is you need to run premium gas after doing that. And if you want o advance your timing just get a timing gun and turn your distributer
You´ll only really notice a superchip in an automatic, it improve shifting, in a MTX it´s really a waste of money. If you really want to increase hp start off with a cold air intake, then work on your exaust. I bought the intake for my 99 Ford Contour Zetec at http://www.ctamotorsports.com/
Chris Wong is a great guy and knows his stuff. I ordered the Intake on a Monday, and recieved it on a Wednseday all the way from Canada.
My roommate just bought a 97 escort sport this morning and I´m about to order her an intake from the same place.
Sorry to burst your bubble, but putting a Gen 1 GT computer on a Gen 1 LX will not work. Since the LX was throttle body injected it only has on injector. The GT has 4 injectors, but they are batch fired 2 at a time, so you would need atleast two injectors to get the GT computer to work right. Your best bet would be to start out by getting the header off of a Gen 1 GT, then get an intake manifold from a Gen 1 GT or a Gen 2 LX. I´ve seen Gen 2 LX manifold lying all over my local junk yard. That way you can use the GT computer, and have more HP to boot. The header itself should give you a decent boost from the way underpowered CFI motor.
My theroy behind the Gen 2 intake is if you go ahead and put the Gen 1 throttle body on it, it might actually be better than the Gen 1. The puny TB is what kills a lot of the power on the Gen 2 engine, plus I would think that SEFI itself is way better than batch firing injectors. The Gen 2 intake is lighter than the Gen 1 intake for one. For two the runners on th Gen 2 intake are smoother, and shorter which promotes better torque in the low end which is what a 4 banger really needs. I recently bought a Gen 2 intake just to see if my theroy is correct. I need to run some baselines first to see where my car sits now after the more minor mods I´ve applied. After I do that i will do the swap, not to metion a bit of porting on the intake, to see how it work out. I will post results as they come.
