I would do ITR cams, cause you can use those in the future with boost. i would do a Intake manifold, cause you can use it when you go turbo.

I woldnt touch the internals, cause thats ALOT of money to sink into a motor and bumps it into another price range. I would do the swap, and wait to go turbo. if your plans are for 200-250whp turbo, a stock b16 can make that easily with one of our turbo kits.

if your goals are 300+ then you need to start looking at forged rods and pistons. Which is ALOT more money as i said. Porting and polishing a head is not worth it on a turbo car IMO, stock vtec heads can make 600whp. you dont want to use a cast piston (like an ITR) because its not worth it for boost. the ITR/GSR pistons have stronger ringlands, but in essence are the same flawed desgin as a OEM cast piston they crumble under detonation. if your gonna spend the time and money on internals, look for getting CP pistons and Eagle Rods.
