Anyone know where i can get an excellent port, polish done in melbourne?

Also wanted to know who can customise fitting a 4k crank into a 3k block?

Cheers

should be somewhere on this site. Heard of using Charade rods but not sure.

Charade pistons... :cool:

 

I've had a word with the young fella, I think he may have changed his mind about this endeavour

Definently have changed my mind :lol: , planing on using forged high compression pistons, forged 3K crank and forged piston rods (most likely custom made).Question is will i be able to bore the block out to 1466cc or am i still limited by the stroke of the 3K crank.

An i know fellas that its gona set me back abit more and that you will tell me just to put a 5K motor in.But i love my 3K :cool:

Is this going to be used for motor racing where you have to adhere to guidelines? If not, I don't fully understand how you can justify all the work and cost involved, when that money could be spent on a 5K or even 7K which will ultimately put a bigger smile on your face.

 

Just seems like a roundabout way of doing it. After all, the 3K is not superior to any other K motor.

No its not for racing.I understand your point of view.You say 5K or 7K will put a bigger smile on my face but why stop there maybe 2TG or 4AGE then i will never stop grining.The fact of the matter is i allready have a 3K in the car and its in very good condition.Planing on going forgies due to my heavy foot and would love for the motor to last a long time, for i am planing on keeping the car for a long time.I will be rebuilding the engine myself which will be a learning experience and have someone that can hook me up with the parts.So just needed to know whats the largest piston size i can go and where this will take me in terms of displacement.

you could try to get the crank offset ground to gain a few cc's.

I hope you realise a custom crank is going to be at least $4k+. Custom pistons around $1800 and custom rods about that much again. So $7600 just for pistons rods and crank. Man what a waste of money!

 

Seriously forget the forged parts...you don't need them. Get a 5K, this will save you having to stuff around with bore sizes and stroking. Then just rebuild it with cast pistons and standard crank and rods. There are people on here making well over 100hp with these sorts of parts... its all in the preparation. Where you need to focus your attention then is the head, camshaft, induction and exhaust.

The only reason that I suggested going for a 5K is that it bolts straight in, and you most likely wont need to get it engineered unless VicRoads questions you. 2TG etc will need engineering, therefor that didnt even enter my mind.

My 5K runs hypertec cast pistons from a Gemini. I have had no issues with cast pistons, hence i don't see the need to lash out on Forged items. Stock balanced bottom end is fine too.

 

Its claimed you can bore a 4K out to 60 thou over (1.5mm). After that, your into unchartered territory for most people and engine reconditioners will tell you that they wont be responsible if they machine into a water jacket. A 3K can be bored out 3 or 4mm. Apparently the 4K's have thinner bore walls.

 

So to answer your question, about 3mm oversize pistons. Last time i checked, the max off the shelf item was 60thou. So i guess you would have to scour the catalogues to find a suitable item to suit.

Which is why the 5K option seems more appealing. 80.5mm Standard and mine is bored out to 83mm. You will spend the same amount of money rebuilding a 5K as you would have spent on a 3K. So the only initial price difference is the cost of a 5K engine. Whats a few hundred dollars at the end of the project.....

I hope you realise a custom crank is going to be at least $4k+. Custom pistons around $1800 and custom rods about that much again. So $7600 just for pistons rods and crank.

 

i couldnt justify that much money on just those parts for a 3k! :)

I miss not having a Ke20. I was going to put a 4AGE into one. That's the way I would do it. :)

 

Yes you do need to engineer it, but if you consulted a good engineer and stuck with him and every bit of advise that he gives, you can't go wrong.
