My advice is, when you start talking about high compression, naturally aspirated engines, you need to rev high to take the best advantage of it. That's GTS territory there. The pistons would probably give 5-7 hp tops with the overbore too. You'd end up having to use higher octane gas too. And considering the cost to machine the block, it's not worth it. If you want big NA numbers save for a 2zz, if you want big Turbo hp numbers, save for low comp pistons and Turbo.
