Higher Revs

[cormac163]

i have decided that i am going to build myself t4 engine for my turbo so i will get much more time out of it. But before i start with the engine i want to know what the best way of getting the most revs are. I am only looking at max 2.1l and i have little knowlege of head sizes for a type 4. R there any good rebuild books on the subject mainly the car is a daily driver which i will use for the odd track day. I do mostly motorway driving but i have 12 miles of windy country roads to get to it so i like to spin up quickly. whatcha reckon on building from scrtch or buying on old box and sorting it out myself.
thanks
