Has anyone actually raced a 2000 Celica vs a 2002?

[Lomeinhu]

I know there's a bunch of stuff about how the 2002 GT-S's have a lower rev limit than the 2000-1 GT-S's. At the same time, there was a slight change in the shift gates and a lockout mechanism installed halfway through the 2001 models that made it harder to misshift (supposedly). My question is: do the changes actually make the different years perform differently. Now i don't mean the manufacturer's time because they don't really push the car that hard. But for someone who regularly hits the tracks, does he/she know if the years make a difference in speed? I'm wondering because if a potential buyer knows that 2002's perform worse and since a lot of us seem to be really concerned about 1/4 miles times, then he/she'd want to get a 2001 or even a 2000 GT-S, right? So i have these few questions:

1. Any changes in 1/4 mile time?
2. Any changes in regular local-to-highway acceleration, regular shifting?
3. Any changes in shift feel (quicker, easier, not as involving, not as close, smoother, etc.)?

I'd also be interested in a dyno comparison between a 2000 and a 2002. I don't think anyone on this board with a 2002 has dynoed their car yet.

i dont remember who it was i was talking to but they had an 00 and it was in an accident, they were running 14.7s in their 00... well they bought an 02 to replace it and they couldnt break a 15.2 in the 02.. he said he was sure it was the car.. who knows.. not many 02s on te board it seems.. hopefully some of em will get to the track this season and let everyone know for sure..

If I knew where to 'dyno' my car in Toronto, I'd do it. I'll look into it.

But from what I know (not much) dyno'ing won't show the difference in shift times. Don't you dyno in only one gear (usually third??)?

I can confirm that the rev limit is in full effect at 7800 rpm. Today for the first time I tried the one two shift and couldn't keep it above 6000. I hit about 5500 the first time, and 5700 the second time. I'm pretty sure that with a bit of practice I can shift from first to second and land on 6000 rpm. With a short shifter it would be no problem.

[larryd]

yeah, dyno will only show the power in that gear which is a one gear run.. which yer results should be same as that of an 00-01 model.. just for some reason the 02s would be slower with the lower rpm.. or atleast you would think

[ToJo]

By the time the rpm cutoff at 7800 occurs, the torque has long since dropped off, and the horsepower has peaked, so I don't see why it should matter so long as you can keep it in lift.

I've found a place to get my car dyno'd. I'll see what their schedule is and maybe have something by the end of the week.

I expect it to look the same as a 2000-2001 dyno.

Eventually I'll have 0-100 times too.

I'm an amateur, but I'd say even 2000-2001 drivers should be shifting slightly before 8000 rpm.

[larryd]

actually you are incorrect.. with an Injen CAI, the max hp is at 8300rpms :)

This is very true. If you look at the known changes, the dyno shouldn't be different. It will just be harder to stay above 6k. If you can do that with an 02, however, I don't think it would be slower than the 00 or 01.

I have a 02' GT-S. I have landed the 1-2 shift only once. The closest I can come is 5800-5900 consistently. I do have a shortshifter as well. I'm going to the track on the 13th so I'll post what times I get. I also have an Injen CAI which will probably make a difference. One other thing I ordered a 00' GT-S ECU for my car. I'm going to old off on putting it on to see how I do on the track. I'll also let the 02'ers know if the ECU swap actually works.

P.S.- I had a 00' auto GT-S and traded it in for this car about a month ago.

LarryD: Unfortunately, Toyota isn't optimising their car for aftermarket consideration. I suppose if you're putting an INJEN CAI in, you can also find a way to fiddle with the fuel cutoff.

Why do we not have some simple ECU modifiers? How tough can it be?

[larryd]

to remove redline.. its prolly not that hard for an eletrical engineer to figure it out.. hehe.. but that Im certainly not :)

It is harder than you think. Even OBD-II Hondas were hard to chip. Someone also has to decide it's worth the investment. I honestly don't think they would sell that many of them.

everybody interested in a rev limiter change, look at the Weapon-R ECU thread.

leo has said he will test it out either this week or next and let us know how it goes. if he can do it, it'll cost $100 plus shipping your ECU in to them to have some crystals changed.

this is the only way to move the rev limiters on our cars, except for getting a whole new ECU.
