Thanks Guys, I see the issues....
In saying that i have made perliminary drawings and have sent them to STS, Garrett gearhead.. they are both showing interest in my design, my calculations with a VGT turbo show that this could be a dead end due to the rods being so weak, (with an engine rebuild (strengthen) this has potential to be a very mean engine) im looking into the rear and mid mount turbo setups now, they might be an option as the power is much more gradual.
