I did mine on a tight budget on my first build. Was just a standard 2 litre silvertop with 1mm skimmed pistons and ARP rod bolts, stage 3 T3 on cvh manifold with adaptor plate, rover turbo inlet manifold with adaptor plate, omex ecu, bigger front mount and an oil cooler pretty much. Lasted 3 years at that. Was set up at 255bhp at 14psi, but i turned it down to 11psi. That was with a deisel box with an RST LSD. Had my fun with it, killed it, now doing properly thanks to the boys on here
