I know I cant reach that but would try to get the most out of the gearbox.
That engine lives from torque,you wouldn´t be happy with a short ratio box imho.Much different than most type 1s.Sepang is a very fast track,you will lose time with a short box.
If a 5 speed is what you want I would go with a 915/03 box ratios:
1.) 3,181
2.) 1,833
3.) 1,261
4.) 0,961
5.) 0,758
R+P: 4,42

You could go with a 245/30 18 tire and be plenty fast enough to leave the Porsches behind you.

As a 4 speed a stock ratio trans with 3.44 R+P works really well on the track.The Rancho pro street 3.88 and 0.89 4th works really well also.
