How much power could a stock auto/box handle?

Full 3carb/header/cam ?

Is there a nicer box that could be bolt to the engine ? A later 5 speed auto with all those nice gizmos... sequential ?

I don't know about it's strength but the U.S. Maxima (RWD) auto is a four speed and it bolt up to a L engine. Don't know about it's fit in an S30 or what the car is called over there. Perhaps a 910.

The Jatco trans was used in a number of cars and small trucks, so that might give you an idea of how it holds up.

The Jatco trans had a couple four speeds- one with a hydraulic lockup converter, and one with electric. Will is working on how to hook one up to the L28 engine in the S30 car. Mostly you need a modified trans mount and custom drive shaft.

Well a Maxima over here is ... a Maxima !

Back to the post, who have a perfo/auto in the club?

Could it run in the low 8' for the 0-60 Miles whithout trashing the box?

The handling of the Z is so Kart like that a perfo auto/Z would be fun (if not the fastest) around a track, no?

I am exploring the 4 different varieties of Jatco 4NB to find which one is the strongest-probably for the same reasons you are asking these questions.

The swap from the Maxima OD has been done, and is outilnes in a tech article on one of the other Z sites. I had no involvement in that, buit it looks fairly easy to do. The reccomended autood tranny for a high output engine is the Jatco out of a Turbo Mitsubishi starion, add to that some 300Z pieces, and you have the group the author of the article reccommends.

I went looking for the article on both HyridZ and Zcar.com, but did not find it.

I did copy the article, and will see if I can I can find it.

My first Z was an auto and did 0-60 in about 8.5. Trans held up fine for several years. I used to manually shift it a lot on windy roads, never had any trouble with the transmission at all. I had planned to swap in a 5 speed but got rear ended and the car was totalled.

I did the 4n71B swap in my 78. You need to remove the trans mount ears from the floor pan. Have a driveshaft made and add a radiator with a fluid cooler.I fabricated a trans rear mount and wired the inhibitor switch. The rest is pretty much a bolt on. For hi performance use there is a company in AUS that makes HI PERF parts. I found their web site by searching "4n71B transmissions". I did the conversion to make my car a better road car. RPM's dropped to 1200 at 60 MPH.
