5k Help

[Peter]

Sorry Rob,

 

Maybe It's the Mid's, but I can't actually see what actuates the butterfly shaft.

 

I see the return spring and the cable attachment but no linkage btw them and the butterfly shaft, is it hidden behind something in the photo?

[Redwarf]

Is this better?

sorry, a little off-topic here; but can you bore a 4k out to 80 mm?

[Super Jamie]

you wouldn't, the bore walls are pretty thin even at 060 (76.5mm), i think my 060 4k has about 3mm to a water jacket at its thinnest, 4mm for everything else. just get a 5k block

[blown 5k]

Trd pistons would bore 3mm over and 4mm over,i`ve heard of people getting away with boring out a 4k to accept 5k pistons so yes it is possible.Trd used to recommend pressure testing the block once overbored,ive had a 3k go porus at 3mm over but ive also got a 3k bored out to 4mm over and it has heaps of thickness left.

[Super Jamie]

3k is different block again. 3k block with 4k crank is also do-able

[blown 5k]

Yep i`ve got one,3k block+ 4k crank bored out 4mm=1430cc 3k.

Got my 5 speed gearbox out of the car at the moment to replace a front oil seal. The 5 speed mates up to a 4K-C as a daily drive.

 

Just aquired a 5K-C last night and brought it home. Quickly mated the 5 speed box off the 4K-C upto it, and it mates perfectly.

 

Hope that helps.

 

That sure was a great 5K buy you got for $ 500.00. We're all envious.

 

:P

lol

 

on the weekend I'm picking up a running 5K for $150, and a good 5 speed for $30

 

Bahahahah :P !

[Banjo]

Teddy, what a find ! And I thought Justatoy got a good deal.

 

It sounds like you have a friend or someone who doesn't really know the worth of these 5Ks.

 

It shows there are still some out there to be sourced, but heavens, there are hard to find.

 

I've been searching for 5 months. Previous ones I've found were all in places like S.A. or Tasmania. I go mine on the Sunshine Coast, a mere hour odd drive away.

 

I'm like a kid the night before Christmas at the moment; Can't wait to get into it this weekend.

 

Mine has 160 - 165 PSI on all four cylinders, and very smooth running, so I'm rapped !

 

I'll let you know how I go, & what I find.

 

:P

Banjo: There's a 5K in a Corolla at the Wacol wreckers, I think it even has a 5 speed bolted onto it!

Bahahahah :D !

was your gun loaded???

 

what a steal. :P

 

well done.

 

tony wants to know if he can borrow your gearbox for the next rally, and does it come with a gear stick??? :y:

sorry, a little off-topic here; but can you bore a 4k out to 80 mm?

yip i've done one. it went out to 5k(80.5)

the guy who bored it thought i was nuts, i only wanted to see if there was enough meat in the bore to do it.

 

big surprise, the block i used was a 81 4k from a ke70 auto, there was heaps of meat left in the block, i ran the engine in a ke30 auto, just standard.

 

the only thing i found was a small temp increase on the gauge.

 

not recommended for making big HP!!!!!

[Mr Revhead[RL]]

we struck a wee prob with flirtys 4k.... the 2nd block we tried to use had been bored out.... to take mazda pistons! i wasnt there when it was measuered but the local machine shop reckon you coul dhave stucj ya finger through it in places! :P

[dingo ke55 5k]

i swaped a 1972 mazda capella that was stuffed for a 5k. i also needed the space so it was a win, win situation
