KE-70: 4K engine tuning..

[D7zul]

Arghhh.. I GOT PROBLEM..

my 4K engine when i slow down in gear 2.. everything normal..

then i full throttle it, it goes jerking... do u think it was the clutch plate?

at 1st i thought it was this thing (refer pic) coz it was leaking fuel..

after change it, still d same..

any ideas?

time to upgrade the carbie

u've read my mind.. haha..

still not satisfy 'playing' with the stock carb.. i think wanna maintain it for a few more months.. juz wanna know the highest potential of the carb..

i'll clean the carb & check spark plug 1st..

thanx guyz..

 

[BLANk]

D7zul,if u want very good aka low fuel consumption & a little powah then u can consider

the megavalve aisan carby...hehe...

if u are those GK then better go for weber dgv/dgav dual barrel progressive carby or DCNF 36/40...

oh ya...forgot to tell u that u need to use the long reached spark plug for ur toyota 4K engine...due to the combustion chamber design...normal spark plug can be use but the umphh tarak~~

sry for the blur pichas...using lauya phone...

 

[D7zul]

BLANk,

those carby plug & play ka?

 

[BLANk]

BLANk,

those carby plug & play ka?

nope...need to custom tapak for them to fit in...price around rm200-rm300 depends on the material,size & etc...

i done mine for rm230+ in segambut foundry shop 2 years ago...

 

[D7zul]

changed my spark plug to a toyota genuine set (as per the box)..

and the jerking is gone.. awesome.. :top:

thanx BLANk..

this spark plug is highly recommended for 4K engine..

cost rm50 per set..

now can drive 60km/h in gear 5.. hohoho.. (if lazy to drop gear).. hehe

future upgrade.. CARBURETOR..

 

[D7zul]

anyone knows what these wordings meant?

スピンアウト　tu maknenye spin out
超 tu maknenye sangat/super
体感　tu maknenye feel/experience
so スピンアウト超体感 maknenye macam really/very very feel the spin out!


Special thanx to doritezza for translating

if exhaust got leak, this thing could happen also.. right?

 

[BLANk]

adoi...i haven't experience this kinda problem before...so payah gak nak troubleshooting ni...happen for long time alrdy?

did u try to pump the acc pedal while cranking?before change the distributor got such problem?the current electronic dist is recon 1 or original denso frm halfcut?

as i knw if exhaust leak will lose powah,noisy & high fc...

 

[D7zul]

unfortunately the distributor is a recond..

don't know how long it's been like that.. i just got this car 3 weeks ago from my dad..

still in 'restoration' stage
