I used a 56a box behind a totally over the top A series for many years and they are fine as long as you are gentle, I didnt need to dump the clutch at 6000 rpm so it survived, overly aggressive launches will take their toll.

Hey mate,

As for the price,id say minimum $aud 1500 for a second hand one(not reconditioned). One that has had a full recondition n say upgraded nismo gear set will set you back in excess of up to aud$3500. So anywhere between 1500-3500 depending on a couple of factors.But alot has to do with the market your advertising to.Oldschool GX5 restorers,Speedway and race a12 cars owners would be willing to pay that much.

According to this site wiki,apparently a14 and a15 have too much torque for 56a.So best suited to a12 although some have mated them to a14s and haven't had any issues.

And if you can't fetch what your after, better to just keep and store it.This gearboxes are getting more rarer.

Good luck with sale!

all a-series , thanks dion

what engine does this attach to?

Hi all, I have a very hard to find ultraclose ratio 56a 5 speed that i am thinking very seriously about parting with, it is in getting new bearings fitted now and i am told everything else is in vgc , so if someone is serious it can be inspected prior to assembly, as far as price goes i am after feedback as to your thoughts, so please let me know what you think, cheers scott
