from your nick...i'm guessing you have an 02 celi...if your production date is after MAY/01 then the TRD
quickshifter will not fit your car. The TRD
quickshifter replaces the entire housing.
However, you can still remove the Shift lever from the TRD
quickshifter and use it in your car. I don't have it but i think it is around a 1" drop MAX. Smooth and soft shifts...but not horrendously different from stock.
I have a 02 also...was considering this...but felt like a waste to pay so much and throw away the housing.
I'm going with TWM because it has the shortest throw (2") and it comes with all the aluminum bushings. Cost $145 US at www.twmperformance.com
or if you live in the states $135 from claremont toyota...call them and ask for EDRICK.
You can also go with B&M which comes between TRD
and TWM i believe. However, i don't think it comes with the bushings.
I've been asking the same question for a looong time...hehe...but do a search you'll find tons of posts.
hope this helps.
