How much power can the std 240z auto box handle?

Full monty ? 2,8L, track day cam, three 45 dellorto, 6/2/2 twice pipe?

Is there any high perfo auto Z running on 6L around?

Is there a better auto box from a later jap car (5 speed auto?)

The JATCO (JApanese ATrnsmission COmpany) made the 4NBL transmission for many years, and that one went into small trucks and other cars besides S30, so I think you could assume it's a pretty good unit. Mine went 120k miles before it went.

Some people were trying to hook up a 4sp auto from the Maxima...

no doubt it's a good product, but is there a better one ? :knockedou

Would a late BMW one fit ???? They also have L6

You are limited to what will adapt, so I don't think there is anything better.

If it (BMW one) does bolt-on, let us know. I want a 4sp auto with O/D and lockup.
