Terrible Performance Between 0 And 40 Kph

My 99 3S-GE Altezza has pretty terrible performance between 0 and 40 kph. Floor it off the line and there's very little power until you get to about 40 kph when it kicks in. (Passangers have the feeling that the driver hasn't put their foot flat) Any ideas what the cause could be? I've cleaned the MAF sensor and changed the oil. This is the same with both ETC PWR ON and OFF (automatic trans)

Thanks in advance!

Altezzas are known to have low power on the low end, then zooms along from 60kph+. It gets better once the engine is properly warmed up.

So, without knowing anything more, it's hard to tell whether your one is exceptionally slow or not. Is it possible to try another Altezza and see if there's a noticeable difference?

There's quiet a bit of weight for 200hp to get moving. Thats the biggest issue our cars face.
You are running 5w-30 too?

the auto transmission won't be helping either. When did you last get the auto looked at/serviced?

the 3SGE loves to rev, the 200hp figures are way up near the 7600rpm mark. at 2-3000rpm the output is less than half that... http://www.beams-redtop.com/blackhome.htm

the auto also puts out less power than the manual.

Same goes with the manual really.. my first gear doesn't pull that well haha. I actually find my gf's rs200 5at better at lower speeds. Probably due to the torque curve the auto 3sge has.

Same situation...
Biggest change (which is like night & day) was getting the lightened flywheel for me.

However I'm thinking its a common issue with the cars, mine exhibits the same thing.

I wonder what blocking off the small intake does for this?
I know Tezz Whinne has done this so maybe he can elaborate if it made any difference?

The only other thing I can think of is perhaps coil packs???
I also ready on the forums that someone changed these which helped them with this issue IIRC.

Would be interested in a solution if one exists also.

It's the nature of the engine and clutch/flywheel design. Can be improved with a lightened flywheel and getting rid of the dual mass crap.

Final drive is another variable to consider, have a look on your build plate and see what you have.

A01 - 3.9
A02 - 4.1
A03 - 4.3

If it ends in A, its open diff, B and its torsen LSD

The higher the FGR the easier the car will pull due to it revving higher right? Eg. the 4.3 FGR will rev higher than the 3.9 isn't it?

Yes, as a result you will rev a little higher to do a particular speed than you normally would. Most people exaggerate this alot and are scared about sitting too high on fwy and using too much petrol.. but in reality the difference is negligible and a good trade off to get extra low down drivablity.

Mines pretty brutal once it drops in to gear:

From my knowledge the difference is about ~300 revs i think.. CLM877's 3sge 6mt with 4.1 FGR sits about 3k at 100kph and mine about 3250~3300 with 4.3 FGR..

Those are incorrect for the RS200. You need to check in Microcat what ratio your car has. Mine is A01B & it's a 4.1 LSD.


From what I can work out, Altezza's came with option of 4.100 & 4.300 in the SXE10/GXE10. IS200 had 3.585, 3.909 & 4.100 and IS300 3.272, 3.727 & 3.909.

Hmmm are you sure? I was under the impression what was on the build plate was absolute unless it's been changed at some point in it's life.

Maybe we need Nick to chime in :P

I'm getting my info out of the Toyota EPC (Microcat) not off the internet, even then ToyoDIY lists RS200 from 1998-05/2001 had 4.100 & facelift had 4.300. I think it was Noel that put those ratios up you've found & he got them from a Lexus forum originally.
