you know what, thats true to an extent... i love the 2zz motor, and i think the sportivo is a very good performing car, but at the end of the day, you're driving a corolla... and whiles its great because its got a nice mix of performance, and fuel economy, and family-car-ness, its not a high performance car, and its not really designed for the 1/4, or the track. its designed to be driven around the streets, and there's the opportunity built in for some spirited driving... if people wanna spend the money on something they have been shown is better, why not go for it? if you're not keen on spending so much on your corolla, don't... but leave those guys alone who have, they just have different tastes and aspirations for their cars than you... if CES made a 1zz exhaust system that was nice and cheap, and it proved good gains, id buy it in a second... but im just one of those people who can't justify so much money on my car in that area... I really don't know why this topic is constantly pursued. I realise now why I no longer have the desire to check the forums daily as this is all that seems to go on. The information sharing has slowed to a dribble. As mentioned above and also in other people posts: ~ A high 14 second pass doesn't really excite me and spending in excess of 10k for the sake of a second is just a pure waste of money. ~ A Corolla is not a track car. Its fun for a fang and upsets a hell of a lot of poeple at the lights but thats about the extent of it. ~ If your a true racer, sink your teeth into something with big cubes and a top loader feeding power out back through an LSD. LOADS more fun and huge smile factor. As Rob said, even something turbocharged will give you a much larger bang for your buck! ~ Uniqueness is a good point. If you really want to spend 20k modding your Corolla i order to beat an R33 that can be had for 15k in total, then go for it. Your loss. (Or perhaps your just loaded!) And finally.... ~ You probably wont ever see my Corolla on the track or the strip. But you will see it cruising the streets, turning heads and possibly even parading random hotties LOL! Over and out! Mick = right. Don't be a bum and 'not' come on the forums tho man!!! There's lots of other fun things to do on here! Like post random monkey pictures!
