hey guys, im new here in this forum and im hoping someone or a few people can help me. i have a 06 corolla le with 60k+ miles on it and i live in california (big part since they passed the catalytic converter law)
so far, i have a cat-back exhaust with stock catalytic converter, changed the resistors for the air intake sensor, a throttle body space, front sway/strut bar, amber fog lights, 50/30 tint, 300 wat amp with 2x12'' kickers, 6.5'' dvd touchscreen console, and alpine speakers and tweeters. wheew...
lol i started just fixing up the interior but switched off to the exterior then i started to look into the engine. the 1zzfe is no longer produced and im just looking for things to up the power without doin anything major like adding forced induction... or atleast prep the engine to take it cuz its hard for me to come up with 1k to 2k to dedicate to one part.
any help or advise is good, anything from brakes to spark plugs lol from adjustments to ratios
oh btw, my budget is like max $200 but prefer like $100 to $150 each part/service
the xrs has the 1zz or 2zz engine? if its the same, watever can be done on the xrs can be done on my le right? well wid some modifications... if its different, wats the difference? the cams?

The XRS has the 2ZZ-GE engine. They're really not the same at all. Different architecture, different bore/stroke, etc. They're probably as different as they can possibly be for two engines that share the same family code (ZZ).
Really, they're very different. The 2ZZ-GE has the ability to alter valve lift in addition to valve timing. The 1ZZ-FE can only change valve timing. The computers are different...the whole deal is really different. Some bolt-ons may be compatible between the two, like intakes possibly, but I imagine that'd be about it. I believe that even the exhaust manifold is different, but I don't know.
Edit: the 1ZZ-FE is most benefited by a manual transmission instead of an automatic. The personality of the engine is completely different with a stick.
aww... so i really cant do anything with this le of mine? thats a downer... anything to make it perfor better? other than the usual of intake and headers?

The truth hurts. But it'll help you make a better informed decision.
Even with the full intake/header/exhaust you're only looking at about 5-10 horsepower improvement tops.
Trading your car in for an XRS is the only viable performance option IMO.

The 1ZZ is a very limited engine. I say this not because of the very weak aftermarket, but because the engine was built near the limit of it's potential. It has a 60mm throttle body (eliminating the need to have it bored and sleeved), a variable intake manifold (eliminating then need for an aftermarket one), the exhaust is almost bang on for scavenging (the optimal rate for exhaust gasses to leave the combustion chamber, so changing to a wider exhaust doesn't give you much), and there are no turbo kits for it.
But since you asked for advice, here is what I would do to make your car faster:
1) Ditch the stereo crap.
2) Using the money you just made on the stereo junk, buy an intake from Cosmo Racing, or make one from parts at the parts dealer of your choice. Bottom line, if you spend $150-$200 on an intake, you've wasted your money.
3) Buy lightweight wheels. They must be 15" or bigger to clear the brakes, but should weigh less than 20 lbs each, and ideally, 16" or so to get a decent choice in good tires without limiting your options.
4) Buy a carbon hood/trunk. The style of hood doesn't matter, it just needs to be light weight.
5) Swap over to a manual transmission. I leave this far down the list because it's difficult and expensive.
6) Focus on suspension. Drag racing a 9th gen is a waste of time. You'll have far more success on a road course.

I agree with everything except this one. A 9th gen Corolla (even an XRS) isn't going to give any 1/4 mile times that really impress, but bracket racing is all about consistency, not raw times. You race against yourself:
A 9th gen Corolla could be very competitive against, say, a brand new Corvette. Even though the Corvette would smoke the 'Rolla in a heads-up race, in a bracket race situation, the Corolla driver would be allowed to leave the line much sooner than the 'Vette driver (based on your dial-in times). Whomever crosses the line first, but doesn't go quicker than his dial-in time, wins the race.
