Order Of 4K Upgrades

[rolla_ballin]

hey people

 

at this stage ive saved enough money for a webber carby,exhaust and extractors and a cam cut

 

i have to get abit more out of the old 4k

 

its quite old 323 ks and a 4 speed box.i was chatting to altezza club the other day he helped me alot untill i found compression test hadnt been done

 

i have to get my a compression test done as a mate told me a few weeks ago he done 1 i just found out this morning he was flapping so ill get that done 1st before i do anything else

 

out of the carby exhaust and extractors and cam cut which would i do 1st is there some form of order for these.

 

also what would be the next step after that as ill start saving up the cashflow again

 

any help would be great

 

cheers

Thanks mate extractors at the same time as exhaust??

[rolla_ballin]

Also what type of. Exhaust I want it to be quietish but when I step on it it gives that growl to it any ideas??

well, Do the exhaust, take it to your local shop and have a chat to them. Nothing bigger then 2", probably 1.75" and a nice muffler. lets be honest, 4k's don't so much growl as squeal when you boot them, soo your better off just aiming for a 'nice tone'.

 

Then, do your cam, and with the money you've got for the carby, buy rings, bearings and gaskets and give the engine a hone and then bolt it back together. Having a solid engine that'll last is worth more then a carby and if it goes it'd probably just lunch your new cam anyways.

 

... and then save a few more $$, and buy a carby, or just get the stock one tuned by someone who knows what there doing, and you have a sweet 'rolla.

Yea good point how much would the rings, bearings and gaskets cost ya reakon?

This is where you start getting into the 'maybe upgrade to a 5k' area. Its a slightly better platform to start with. (if you can find one)

 

If your taking the engine apart may as well do the head, at least shave it slightly, maybe port it.

 

I paid around $60 for a full gasket kit for my 5K but that was awesome mates rates.

Slow down a bit and figure out how fast the dollars are coming in.... You'll have to get prices locally, as we all have mates who can do different things for us.

 

Do the compression test and decide how knackered the motor is. If it is good then hit the mods-

 

Exhaust first, which means extractors, a 2inch resonator under the passenger's floor and an inch and 3/4 pipe back to a tri-chamber muffler. No change out of $600 odd. That system will fit any K motor you use.

 

If you have the money, whip the motor out, the head a once over, fit the new cam and fit the Weber. Run it for a few years until the rings or bearing need doing.

 

If the compression story is bad news and its pretty worn, then you have to pull it all into pieces. Then the engineers shop will tell you how bad the bore is, and whether its a rebore or just a hone and new rings.

 

If its just a hone, then new rings, new bearings, lighten the flywheel and balance the whole system would be great. That would make it rev smoothly with the new cam/carb/exhaust.

 

If it needs a rebore you really are at the top end of the spending... Get the block sonic tested to see if it will take 5K pistons, giving you a 1500cc 4K, and have it rebored to suit. New pistons, new rings, new bearings, lightened and balanced.. no change out of 2grand I'm sure!

 

But then you have a motor that will not only fly, go up hills at 100kph without slowing, but it will last a couple of hundred thousand Km.

 

So- start by seeing how good the motor you have is, what needs doing to take it back up to "as-new" status, and then lay out a budget to mod it. You might need to do a rebore first, and run the stock carb, cam & exhaust until you can afford them. If the motor is out for a ring job, see if you can get a cam ground then, as its a pain to try and change cams in the car. Carbs and exhaust can be done anytime, although best all done at once as you can really see what you're doing.

 

good luck with it
