I respectfully disagree. But first, yes, a 1.3l will be a 1.3l, if you are looking to squeeze a few more Nm or bhp it is kinda pointless as it will never be a 1.6l, no replacement for displacement.

I don't think the TS is going after a monster racer. From his list of mods, I surmise he is just looking to improve driveability, maybe some spirited short sprint whenever the opportunity arises. As for handling, you don't need a powerful car to throw your car around corners. Whats wrong with wanting a smoother, more eager ride to let off some steam on an empty stretch of road? If the TS wants to challenge larger cc cars with a 1.3 mill....well then too bad lah (Actually, I believe it can still challenge a 1.5l Dugong) .

As for the bit where torsion beam not for aggresive driving, look at the Fiesta ST and Megane RS, 'nuff said. Of course, the Saga is different, but it is not half bad even with stock suspensions.
