Could It Be A 5 Speed Automatic Gear Box In An R33..

[iseekool]

is the 5 speed box better (stronger) than the 4 speed?

I'd say the 4 speed is physically stronger, but having 5 speed would be much nicer IMHO.

ive been told by an engine importer that the 5 speed is weaker because its for NA and the innards of the trans are smaller to fit in the same basic housing as the 4 speed

sounds about right.

ive been told by an engine importer (scott at Iichi Ban) that the 5 speed is weaker because its for NA and the innards of the trans are smaller to fit in the same basic housing as the 4 speed

and who knows what ratio 5th runs at?it may run at the same revs as a 4 speed at 100 kph therefore no gain in the 5 speed

[mad082]

probably not the exact same ratio, but it would be close. they usually the case in all cars. final ratio for top gear is usually the same because the cars have enough torque and get the best fuel economy with the gearing at a certain rev range

a few years ago i was gunna chuck one of these 5 speed boxes behind my S3 RB30E R31, but was told there might be wiring issues as well

I imagine the "extra gear ratio" will slot between 3rd and 4th. As I feel there is quite a gap between 3rd and 4th gear in a conventional 4 speed auto box.

[mad082]

all the gear ratios will be different to the 4 speed. they haven't simply thrown an extra ratio in.

I thought all the automatic r33s got 4 speed gear box, but when I listen to my car, its voice drops 4 times after it lauches, I mean I can hear it changing gears four times after when it accelerates from the 1st gear, which means there should be 5 gears in it!! Is there really any 5 speed automatic gear box exist for r33? or my gear box is just wierd? or it changes 4 times just mean it's 4 speed?...

Can any expert give an answer...

Yes, there is a 5 speed auto.

From what I can establish, they were only fitted to 4 door N/A r33
