turbobill.... what's your target BHP? This will determine how you do it, what you need and what it will cost.

Waynes for example is a low power, low budget build that will make around 200bhp and cost around £1600-£2000 but that's with labour and he already has new management, if you can do it all yourself then it would of course be much cheaper.

Both Mark and Stu speak of around £3000 which is about spot on for a stronger, bigger power build and thats doing all the spanner work themselves, if they had labour on top of that it would be £4000 plus.
