Hmm, looking around for suitable cars, I'm considering a 2003 car with the 6 speed gearbox.
I'm just thinking though - considering they've squeezed the extra ratio in there, is the 6 speed gearbox any weaker than a 5 speed, or more vulnerable to failures due to the extra torque?
I haven't heard any nasty stories. And it's basically the same as the box they use for the 190bhp celica so it should be fine.
The only bad things I have heard is the increased possibilities of a mis-shift due to the closer gate (and driver error) - ie. 5th to 2nd instead of 5th to 4th and subsequently bending a lot of valves s:? :? s:?
The 6th gear is an add on to the 5 "original" ratios, so acceleration wouldn't be any faster, and the 5sp will (allegedly) take you to 152mph anyway (cue mph s:) :) s:) ), so other than autobahn cruising or track work I don't think it'll make a lot of difference which box you use.
IIRC the 6 speed gearbox on the J-spec roadster has shorter ratios and a different final drive to the UK 6 speed (provides more rapid acceleration over the UK 6 speed), so if you can get one it should be better...
...maybe s:wink: :wink: s:wink:

Correct
if i remember rightly and somewhere on here, there is a chart (but i cant find it s:( :( s:( ) the uk 6-speed gearbox was basically the same as the 5-speed with an extra ratio added on top, presumably for economy
Ekona is going to fit the Hass to his standard 03 model 6 speed. I'm sure he will let us know how it goes s:crazyeyes: :crazyeyes: s:crazyeyes:

Fast at a guess s:twisted: :twisted: s:twisted:

As does the J-spec 5 speed. I think it's only the final drive that's different in each case.

US / J-spec ratios were the same I believe, but the US didn't get a LSD.

Did someone say track work? s:wink: :wink: s:wink:
That's definitely on the cards once this is all finished ..
But it is good to hear that there aren't any known issues with the 6 speed box - doing some nosing around on Spyderchat I found this:

US have a totally different set of ratios to both UK, EU and J-spec

Ta for that link - that makes interesting reading, as do some of the links onwards from there.
One other thought - are components such as the clutch and pressure plate common between the 5 and 6 speed gearboxes?
I would expect so, the clutch and fklywheel sitting in my garage are for 1zz celica and mr2
in teh celica it's 6 speed only.
I've got a 5 speed if you're looking to swap s:D :D s:D
LoL! Nice try s;-) ;-) s;-)
