I can try and get some data for you. Andrew (my brother) has his (standard) car in the workshop following a head gasket problem after a thermostat failure, and we're hoping to take it to Snetterton later in the month for a track day (although I'm only coaching not driving).
I looked at Toyota's torque curve and modelled that with a 15% transmission loss, which I have attached. yours wasn't far off at peak power and beyond, but lacked a lot of midrange power/torque.
Toyota claim, at the flywheel, peak power 108bhp @ 6400rpm and peak torque 97 lb ft @ 5200rpm
Manual Gear Ratios
1st 3.166
2nd 1.904
3rd 1.310
4th 0.969
5th 0.725
Reverse 3.250
Final Drive 4.312
Auto Gear Ratios
1st 3.643
2nd 2.008
3rd 1.296
4th 0.892
Reverse 2.977
Final Drive 2.962
Standard Seras don't have a rear anti-roll bar at all. Some people have fitted them to try and reduce understeer, but usually without any scientific reasoning or calculation - they just fit a Starlet one and think it will be better. Andrew has seen one fitted to the axle, but not to the body (so it didn't do anything other than add weight) and the owner was convinced it made the car so much better!!!
With the gearing and power corrected, it's actually very nice to drive apart from the oversteer. Reducing the ear anti-roll figure to 200 doesn't make enough difference, so there is still work to be done there. I appreciate that front engined FWD cars can be made to lift-off oversteer in some cases, but this is extreme and even when driving slowly, given that sims make it very easy to overdrive, it still does it way too much.
A good base to build on though. Keep at it and Andrew and I can try and provide any data you are missing.
The 3D model is simply superb. Perhaps a little low-poly around the hazard light switch, but that's being REALLY picky.
P.S. I won't be sharing, stealing or doing anything untoward with your data file contents, I promise you that.
