found one or two references to a getrag 6 speed swap in an aristo.. but couldn't find any info on how to do such a swap or what parts are needed.

anyone have any idea how to go about doing the swap?

Gaz Walker did some work on tyhis...........need shed loads of money.........from what i remember the speedo display needs replacing as it gets all its signals from the gearbox & engine ECU's which dont work without each other (so need replacing) a lot of other electrical stuff needs changing as well...this applied to mark 2 cars 1997-2005

sorry i should have put year its early 90's

92 to be exact

There's a MK1 Aristo currently in the UK with the 6 speed swap, you'll find it on www.mkivsupra.net/bbs or www.lexusownersclub.co.uk

Not alot of help, but always best to get the facts from someone who's done it/or owns one.

Yeah that was my car previously. He doesn't know how the conversion was done as neither do I as the car came from Japan like it. I can tell you it had the stock aristo ECU in it which I replaced with a stock supra mk4 manual ecu. AFAIK the speedo unit is stock aristo on that car as well. Its a 95 plate so mk1. I am looking at going manual on my car again as the stock box doesn't go well with the AEM I chose as my engine controller.

I figured it out. Pay someone else to do the job £3k roll in roll out job done.

6-speed swap on the Aussie forum: http://www.jzs147.com.au/forum/viewtopic.php?t=212

They are cheating by breaking a car which was already converted to manual (they can't register non-standard cars), but it should still illustrate the changes required.

for the swap you can do several different methods for fooling the ecu, one is to select neutral on the electronic shifter before hiding it away.

another is to give a perm neutral signal to the ecu.

it isnt quite as expensive as most originally thought it was, more a case of solving the electrickery first

i read in banzi i think that its possible to do a 5speed swap could work as good . ill see if i can find the issue

Yeah I have seen some in jap auctions and new zealand with 5 speeds but the 5 speed box you would use would have a similar power ceiling to your auto box so a tad pointless.
