If you are keeping with pinto pistons, try to source a transit bottom end as these are lower compression height pistons and are ideal for turbocharging up to 250bhp!
Thanks again Karl, very much obliged indeed. I had planned to go for the standard crank, H beam rods and forgies or similar to drop the compression aiming for about 8:1. I also bought the inlet manifold to suit but it has no plenum so I will have to make one up. I'll keep an eye out for the cossie management, I'm just starting to collect the bits so theres no rush. 250hp would be fine but if the bottom end was built for more it would be peace of mind and give me somewhere to go in the future.
Again to everyone, Thanks heaps for the help. -Andy
