Hi all I currently have a 3k in my ke30 and I'm looking at buying a 5k block from another rolla club member. Where I am stuck is should I use the head Carbie etc off my 3k and make a frankenstein 5k or buy stuff specifically for the 5k? Us it best to do a bit of both ie use the 3k head but buy Carbie and intake for a 5k?

I'm also looking at doing this so I'll be interested to know what you end up doing.

There's a few options to run with... I found the 3k carb is too small for my hot 5k though others have made it work.

It all depends on what your getting with the 5k and what you have under your bonnet.

what does the 5k come with? crank, conrods, camshaft, lifters, pushrods? Or just a block?

 

We can tell you what you need if you can tell us what you've got... :happy:

Whole bottom end, rods piston everything been told I just need head accessories and exhaust. Not sure what pistons they are

Yeah that's some critical info. Same with the camshaft. If it's a deep dish piston 5k it could have a solid or hydraulic lifter camshaft and without the lifters, pushrods or rocker assembly it will be hard to tell. I reckon you should ask some questions... like why does this 5k have no top end.

You said it was from a member... any chance you can tell us who your buying it from?

Seller is lxy-642

OK! How much money have you got to spend?

 

If you want the 5k in your car asap you'll need about 1500$. If you can wait, buy the block and start collecting bits.

The engine is a deep dish 5k, i'd guess it's hydraulic lifters cand camshaft.

 

You'll want a rebuild kit to suit, a guess 1988 liteace(comes with bearings and gaskets), also a new timing kit.

The block needs to be dipped and probably rebored. A 4k crank will fit with the 5k rods.

Get a 4k-c head with valves and rocker assembly. Get it it reconditioed if itneeds it.

Get a 4k camshaft. Then, source datsun a12 motor pushrods and holden solid lifters (ebay).

That will get the engine together. Carby and exaust is up to you. As are anyperformance mods you choose.

 

If your serious about spending some coin and getting this thing in your car, get it to an engine builder but expect to wait months.

Or talk to us and build it youself.

Hmm was hoping it wouldn't be $1500 lol is that just a basic 5k setup or is that pretty full on?

the block needs to be dipped and rebored. which in turn means oversize pistons. probably a few hundred dollars

rebuild kit with pistons is about $500

timing kit is about $70

then you'll need to find a complete head, rocker gear, camshaft, lifters, pushrods, crankshaft and probably a few hundred on that. most of this stuff is quite easy to come buy.

so then you look at thermostat housing, water pump, manifolds and decent carb... yeah i think you could get out of it for around 1500$.

unfortunately that 5k won't be just a buy it and slap it together deal because of the condition, missing components and the unknown history of the engine.

 

i'm not trying to turn you off the 5k. i'd say buy it and start collecting bits and getting things done. as long as your 3k is still in the car and running, what do you have to lose.

I reckon buy a running 4k as well as the 5k because a great many parts will be found there.

Sounds like you would be better looking for another 5k that is complete.

I'm running an early 3k carby (pre-emissions) on my 5k. I reckon its given better fuel economy and a touch in power.

But then again my 5k is more or less stock a part from the extractors and 2" exhaust.

standard 3K carb is ample for standard 5K.

 

the rough dollar amount on a full standard build given by GJM85 is spot on.
