I know a guy in Portland who just finished a swap into a second gen 4runner. He used one of their mechanical pumps. He really likes it. Steve has a 3L mechanical pump. I think it might be the same pump body as the one used on the 1KZ-t that came from the factory with a mechanical pump. I would just need to have ot tuned for the 1KZ. Trying to find a cheaper way to get a mech pump on this thing.
