86mm. For 400whp you can use stock bottom end, your main concerns should be top end, management and turbo selection. This didn't deserve its own thread, use this next time AFTER google:

Like already said, 86mm, 8.5-1 compression. You can bore the engine up to 87mm without needing to resleeve the block.
