Well if you mount turbo, manifold, oilconsole, waterpump thing and a intercooler. + a MS ECU your there. Cams with not give so much (about 5-10bhp) and the pistons can take it if you run with 0.6 bar of pressure. I will say that you will hit about 140 bhp... Anyway, you can get 4E-FTE pistons for about 200...
