Building Ultimate 5K

[KE25_rolla]

buy the 4k turbo kit for sale in the classifieds section - best bang for buck. I had a turbo 5k in my old 36 and it flew. Bog stock engine though the

standard head gasket didn't like it. Was running a blow through 1 3/4 su carb. For what it cost it certainly moved!

Where can i find this camshaft, Tighe 104: 25-65, 270 degrees for my old 4k engine?

 

I'm looking for help from all of the members in forum, where can i order this perfomance part?

If someone here want to sell their racing camshaft, I'm willing to buy.. please do not hesitate to email me at [email protected]. or just reply to this topic.

oh, and this like is full of tonnes of useful info. Scoured the net before I decided to

go 3TC

 

k series

dropped the block off today, the pistons and rods looked pretty close to have already been balanced, came within 2grams of each other and they were covered in carbon. bores were pretty smooth and shiny so fingers crossed i can get away with a hone and new bearings and lightened flywheel.

 

the head was have been flowed at 139hp but know nothing more on those details. engine builder and tighe cams have suggested goin to solids so now I'm on the hunt and slightly confused with all the info on the net. Can the 5k accept 202 valve springs and would that be my best bet?!?!?

 

I have a 5k bottom end. 5k twin squish/ really small chamber head, with the 2 lugs on it.

I have a old 4k rocker gear setup, maybe some 4k rods.

 

I read felix i think saying bottomed out 5k lifters, 3k rods and 4k rockers??!?!?!? any info would be great so i can get the cam away for a grind and get it back together.

 

Cheers lads look forward to some info

4k solids with either datto 1200 or Holden 202 pushrods

[kickn5k]

4k solid lifters are way too small in diameter.

 

Can you run a vernier caliper or a steel rule from deck face to rocker face on your 5k head? I can then hopefully see if the chev/holden lifters and datsun A12 pusgrods will work.

from memory 5K heads are pretty short so it may screw with rocker geometry.

cheers for responses. the height of the bottom of the head to the rocker post base is 75.7mm

haha that was quick!!

 

Ok I'm fairly certain I have a savagely decked 3k bigport at home that will be pretty close. I'll chuck it on my 5k I have on a stand and take some measurements for you. Ill be home in a couple of hours.

hahaa yeah i was sitting there looking at it when i saw your post. that would be a huge help mate, at least help me get a start on what parts to chase

[springersrolla]

i have a 3k bigport here and it measures approx 80mm

Yeah you can use the chev/datto combo with a 3k or 4k head on a 5k (I've done both), but not with the 5k head.

[springersrolla]

yeah thats the drama, its 5k head on 5k block, seems theres heaps out there for the other combos. just not the 5k one. ive read felix got away with using gutted ones so ill pm him
