4k Rebuild Or Replace..?? Advice Needed

[Dirty KP]

hi guys I'm a 16yr old teen i live in New Zealand..

 

I'm wanting some advice on wether to rebuild the 4k in my starlet or drop a new worked 4k or rally 4k in..??

the 4k in it at the moment apparntly hase a race cam..but not sure if it actually does as you can usually hear..

and its running allright at the moment but the previous owner said it has i worn big end bearing..

 

I'm wondering which would be cheaper and better..ether replace with worked 4k or rebuild the current 4k..

 

if i was to rebuild the 4k currently in it i would want to work it so it pulls hard for a non turb 4cylinder 1300..does anyone have any advice on what are some good things to work on the engine to make it go hard..(i wana rip past my m8'z 5k starlet) wuld this be easy or shuld i buy a allready worked 4k.??

 

also when i start it up in the morning it is real cold if i try to reverse out my drive b4 warming it up foe about 4mins it will generally stall..

however my m8 starts his up and reverses out straight away and goes but just keeps at lo revs until warm..

any advice on why mine stalls when cold and my m8'z doesent

 

also one more thing..it currently has a 4speed does any one think i shuld keep the 4speed in or go with a 5speed box..??

 

thanks guys i relly need some advice on what to do..=]

any advice is appreciated..

 

i posted the same thing in the wrong forum but not sure if I'm posting it in the correct one this time ether..can someone tell me which 2 post it in and how thanks

oh and as for the 4 speed, if its going to be used for road use i would definately go for a 5 speed, although the 4 speed is apparently stronger

What's your budget. You'd be looking at 1000 bucks for a rebuild, done on the cheap, but done properly.

 

You can probably pick up a warm to hot 4K for that, but you might be waiting a while. In Australia at least, it's not like worked K engines come up all the time.
