Look at all the information - and my own driving experience I would say an 28i with an JB4 Stage 1, is comparable to an N54 Standard.

There is an difference in not having an 3ltr - the power delivery is smooth - but does not quiet feel like the N54 - but not really noticeable.

The only negative is the N20 does not sound like an N54 - but cost of ownership means that I am saving £2,000 per annum which is about $3500 per year.

I would not trade up from an 28i to 35i, but would trade up from an 28i to an 35is.

I am taking the car to an track day next weekend - were they had the F1 race held in the past "donnington". And hoping to take the car to Centa Pod to do some 1/4 goes - hoping to be low 13's but sub 14 secs. Which is similar to an standard 35i.
