I have a 1275cc mini at the moment and I am looking at building a performance engine for it, a few people have advised going for the smaller campacity 998cc block for a few reasons:
1.) Shorter throw crank allowing the engine to rev up to 6500 (as apposed to 5600 for the 1275cc).
2.) More reliable in a high state of tune (again because of the shorter throw crank)
3.) Better fuel econemy.
4.) That my 1275cc head and carb on a 998cc are common performance upgrades in there current state of tune and hence building a performance 998cc motor would be atleast £500 cheaper than a performance 1275cc one.
This all seems to make a lot of sense to me and I figure that although I will lose alot of torque, that a 998cc block with a balanced bottom end, a kent 276 cam and my head should give about 70bhp and be much more revvy (and hence fun) than my current motor.
Are my well advised freind speaking aload of balls and am I being silly or is this a very cheap way of getting a much stronger higher revving motor that will better suit my go kart style of driving?
