I made up a turbo for a 3k I used to race. I used the 3k because I had one that was only 8.5:1 compression ratio and it still allowed me to run in 2 litre class. I manufactered an inlet manifold and mounted the turbo on top towards the front with a cd stromberg carb, although if I did another on I would'nt use a carby I would go EFI. I used a jap Garret turbo off a 300zx and ran 8psi boost and raced it for almost a year without any trouble. It had great improvement at top end and drove well. I don't know how a 4k would go because the comp ratio might be a little high. Also need to fit oil drain in sump. Just make sure you don't run it lean as the pistons in 4k'sare not the greatest.
A heap of work good luck. Rob20v.
