His question (as I read it anyway) is why *upgrade* rather than just find take-off coils from someone who lifted a FJ Cruiser or 80 series. Could easily lift a 3rd gen 4Runner for a lot less money than a new OME kit.
If I had the time, I definitely would. If anyone is selling this sort of stuff, feel free to PM me. I spend the majority of time offshore/away from home and a vehicle. Cost isn't really any issue, and think that the ease of slapping on a new kit is well worth it.
