for a running b18b1 or b18a1, you out your mind, full z6 swap should be around 600-700, pistons low comp or high comp (good ones) around 200...that's still 900...for a swap...like I said I don't need something fancy, if you getting stock motors b18b1 or b18a1 for more than 1,000 you must be out yo damn mind.
