I tested bumping the rev limit to 7000 rpm last weekend One thing that I'm not sure its good or bad is the gearing is quite long, 2nd gear hitting 100++ kmh. Any thoughts guys?

Still using stock m20b20 diff, 3.46 i think. My car can go max 160 only la, hati tak cukup kering hehehe. I prefer bigger(or is it smaller?) ratio for touge. Will 4.45 medium case be plug and play or need mods?

usually m40 comes with 4.10 which is quite reasonable... 4.45 would give u better power at low range i reckon... hmmm 4.45 with lsd... splendid!!! hehe too bad i have yet to come across that..
