Just wondering how hard it is to do a b16 head swap on a b20z? The shop that did my swap wants 1600 (incl. labor and parts) for it.. I saw b16 heads on ebay for around ~500 + shipping. ~$900 labor? What I was thinking was that 1600 also equals the price of a turbo kit, give or take a little. I'm stuck between which route to take. Preferably, I'd like both, but in reality, I'd be lucky if I could save up enough for either by summer.
