MGZT 260 to 300 upgrade

I read recently on one of the 260 V8 forums that the easiest way to get to 300 bhp from the standard 260 bhp is to:-

1. Fit an Acufab throttle body upgrade

2. Fit a cold air filter

3. Fit a throttle body spacer

Overall cost about £400. An easy but still expensive way to get 40 more bhp.
