Hey guys,

 

Long time reader, first time poster. This is possibly the stupidest thing done, but has anyone put a supercharger onto a 4K before?

 

I have a KE20 that has had a fair bit of work done on the engine (Only gets used on a track) and have a small (SC12) supercharger to put on.

 

If anyone has any information on doing this, I would like to hear.

 

 

Josh :D

yeah, brad from oldcorollas had a supercharged 5k a few years ago. it ran lpg through an impco mixer, with an SC12 running off a modified aircon bracket. i believe there is a picture of his engine bay on the oldcorollas yahoo group

Never done it, but, you'd hafta somehow mount it to the engine (use the air-con mount maybe?) jet the carby bigger as the extra air would cause it to lean out, lower the compression etc.

 

Worth a shot. I know a few people on here would like to have a crack at force inducting a 4K.

 

I'd say it'd be a bit of a bitch to get a perfect tune out of it though being a carby set-up and all.

Beat me to it jamie haha.

I'm half way through planning such a conversion. I'm running twin 40mm solexs and a 4AGZE blower. Ive been advised to run no more than 7psi. Just got to get a intake fabricated up. hopefully it should pump out 150 hp.

research carb setups. you could use a weber from a blowthru turbo renault, or an aisan from a turbo charade. or you could use a drawthru setup with some SUs or sidedrafts (or any carb you can make the manifold for really)

 

however you can't run an intercooler with drawthru. its usefulness would be debateable on a forced K motor tho, you can force 6psi into them with no problems, 8psi with reduced lifespan, and 10psi makes them go bang awfully quickly

"Rolla Boy" has done it. He's from the ACT. I don't know too much about his car myself, but here is a pic of his setup.

Apparently it wasnt that quick of a car with the S/C. His 5K is comparable to it.

And another.

brad's first blower setup

the mixer. he did another one, i'll see if i can find it

my mistake, the other one i'm thinking of is this budget turbo 3k

And ive done it.

150hp...7psi 4k i doubt it,i reckon my modified 5k only has 160-180hp on 12 psi.

no 150 hp, no way, we are running 10 PSI, Yes it goes well but not that well, i would think we might be getting 80-90 HP from a 4K

depends what else you do to it. angela from SA has a big dollar programmable efi 5k with custom inlet, hks gt2530 turbo, apexi avcr, blah blah blah and she's only making 215hp at the flywheel

 

do the same thing to a datsun a12 and you get 250hp. k motors just can't make big numbers without spending more money than is worth it, that's all it comes down to
