Six Speed in a 6GC Options

[Fastbird]

I've heard talk of people thinking about it but have never seen any factual attempts. These things need a sixth gear.

I was pondering, and it probably wouldn't be toooooooo terribly difficult to have a bell housing adapter made for something like a 7th gen and then have a custom input shaft in a longer length made.

Are there any other ideas floating around out there?

The U660E is from Japan, and has been put in the late model Toyota Aurion and Lexus ES350 here in Australia.

OK, i am "pretty sure" U660E bolts up to the 3S-GTE:

A 3.5 litre 2GR-FE mates to both the U660E in the Aurion and the U151F in the new Highlander (Kluger).
The U151F will mate to the 2GR-FE as well as the 3.3 Litre 3MZ-FE in the old Highlander.
The 3MZ-FE mates to both the U151F and also to the A541E in the Camry.
The A541E is interchangable with the E153.

It is therefore highly likely that the 3SGTE will mate to the U660E. My main concern is actually whether we can create/aquire adequate brackets and mounts to support the trans in the celica engine bay, and also whether the transmission will actually have room to fit inside.

IF this work, this will be awesome.
