hey guys,

 

i was just wondering if anyone has any sort of trade secrects or anything to help me out here.

 

i have my ke70 with a (as far as i know) stock 4k in it. nothin spesh. all i have done is change the oil filter/oil, and the tappet gasket. is there anything i can do to make it run better? even a little faster... as i will only be on my ps and can't just swap it over haha

Ref faq how to build a tough k motor,

 

Run premium and bump the timing up

alright cheers man. ill give it a read. but yeah if anyone else has anytips like that that would be sweeet!

hi heath.

 

you see questions like what you asked, are just so vague...that knowone is going to bother to answer you.

 

how much cash you got? how much skill you got?

 

have you searched at all? as there are so many threads like this around.

 

remember we are all happy to help a fellow corolla enthusiast, but only for specifc questions that you can tell the asker has already put some thought and research into.

 

here is the thread that evan refers too, a good read:

 

http://www.rollaclub.com/faq/index.php?title=Tech:Engine/K_Series/How_to_build_a_tough_K_motor

 

and the first paragrah pretty much sums it up:

In One Paragraph

 

Don't spend heaps of money, it's just a crappy old K motor. Balance everything if you can afford it. Use a 20-60 cam in a 3K, 25-65 in a 4K, 4K is better. Run 0.400" valvelift, fit heavy duty springs if you don't want the stock ones to wear out in a couple of years, use 4K valve gear. Shim the oil pump spring 3mm for more oil pressure. Run between stock and 10:1 compression. Get the distributor recurved. Fit extractors and an exhaust larger than 1.5" but not larger than 2". Fit a new timing chain and tensioner. Put something better than the stock carby on, but not too big. Don't rev it past 8 grand.

Sadly it is running as well as the Toyota engineers could make it go. You could squeeze a little more with a better flowing air filter, but really more power will involve better carbs, a better exhaust and a better cam grind.

 

Read everything you can find,as the more work you do yourself the greater the modifications you can afford to do. First up, do a compression test and post up the results along with the odo reading if you feel its still correct.. That will tell you roughly how worn the motor is and where to start.

 

Here's what we did, but if you're short of funds a Weber downdraught will be cheaper than the SU carbs. They come up for sale on here, or come off older Fords & Italian cars.

alright cheers guys. see the answers i was lookin for were ones like alrezzaclub and from evan G. i know it was a pretty silly question. but if you go back and look... all i am asking for is any trade secrets. or things other people have done. I'm not lookin to spend a fortune on the bag of fart i have under my bonnet. ill chuck a zorst on it. but haha come on. its a 4k.

 

 

 

i have read over the 4k page. and thanks for the link guys. helped heaps. but yeah again. if anyone has little things they have done. I'm always keen on a new idea. thanks heaps guyz

send me a 4k/5k and ill build a stupid crazy motor for $1300.

Lighten the ʞ©$ɟ out of your flywheel. Trust me. The biggest cheap improvement you can do, and instantly notice the difference. People ask for the easy simple cheap way to make a small power increase, this is it!

What work does this evolve you doing?

It needs to get taken to a machine shop to be done. Usually cost you around $80.00.

7 kg will give you a good weight and maintain some torque.

 

But you must tell the machinist that you don't want any more ʞ©$ɟ in it..you need to take the ʞ©$ɟ out of it.

Much like boiling potatoes.

When you boil potatoes you need to boil "the ʞ©$ɟ out of it" to turn it into mashed potatoes.

Try this while your shaving the ʞ©$ɟ out of your fly wheel?

 

All jokes aside,a lightened flywheel makes these things pick up quick in the revs and it's by far one of the most characteristic changing modifications you can do to one of these k engines :)
