Gearbox Swap

Featured Replies

yeah hey

 

i got my dodgy 4 speed out(of the ke70) and the k50 out(of the ke55)

now the k50 is a bit longer than the 4 speed

but

the 5 speed tailshaft is a bit shorter than the 4 speed tailshaft

so it should be right

 

but the original tailshaft on the ke70 was a two piece (kinda like a big nunchucka...it was fun)

and the 5 speed one is one piece

 

 

Now my question is

is the one piece tailshaft going to encounter any problems

cause of the different suspension?

ke 55 has leaf springs

ke 70 has coil springs

 

any ideas?

 

Will extractors that fit 4K engines fit 5K engines? stupid question I'm pretty sure that i read it somewhere on the forum but i can't remember

 

cause if so i wanna blow up my 4 k and swap the cam to a 5 k and repeat the process

 

it should be fun

extractors are the same :D

sweet, what about the valve springs ?

can you swap out heavy duty ones from a 4k to a 5k?

You need a KE70 5 speed sedan tailshaft (two-piece).

 

If you use a KE55 gearbox you will have a furthe forward shifter position and may have to cut a new shifter hole.

Actually, the KE55 gearbox has a different shifter location to the KE70 gearbox anyway. So if you want to keep your original shifter position, I would recommend you get KE70 5 speed, otherwise you're going to definately have to cut a new hole for your shifter.

hmm, what gearboxes came in 5 speed ke70's

 

wasn't it the k50?

 

the gearbox outa the ke55 wasnt the factory box, it was an auto swapped to a 5 speed

Yes , its still a K50, but there were two different ones.

 

The KE55 one had a shorter shifter position to the KE70 one which had a longer shifter position and sat further back.

 

So my guess is you have a KE55 one which WILL require you to cut a hole in the floor.

what a pain in the ass

 

i gotta get a new crossmember made up

All you need is a KE70 extension housing for that 5 speed, then it will bolt straight in
