i'm planning on swapping my motor out of my 89 HF and putting in somehting a little bigger. this is a low cash project so don't recommend a B16 or something. Besides if i ever sell the car, i'll never get the amount of cash i put into it. All i need to know is if anyone knows some stats on the D16z. i'm trying to decide between that of the ZC. i know the ZC probably has more HP stock but will i be able to get more out of the D16? My plans are to build up the bottom end and run as much boost as i can on it, so i know that the ZC is kind of weak under a lot of boost. also i was wondering if anyone that has swapped these motors could tell me about how long it took to complete the swap. Me and a friend think we could do it in a day, but we've never done a honda motor, just older cars.
