i have no idea what's involved in changing a 1990 NISSAN 300ZX TWIN TURBO gear box

is it just take it out and bolt the new one in or is it alot more (please help me)

its also a auto box

If you are changing to a manual box from an auto its a bit more involved......if its an auto out auto in its a straightforward swop.

if its to come out may aswell do the conversion !

is the stock auto box good for 400hp or shall i change to manual thanks

Go manual anything over 350 and your pushing your luck on an autobox

Contrary to belief, the Auto box is relatively a strong box, many in the US favour the auto's and some have high power through them!

It all comes down to the auto boxes previous history, auto's generally take some looking after and servicing, fresh oil and filter etc. Assuming this has been done like any other auto car, the box should last a very long time.

 

If you've an auto box to wap in, service it first and have it checked by an auto box specialist if need be, auto boxes can be had quite cheap!

Expect a morning to swap a box over yourself or about 200 quid ish from any half decent garage.
