K24 Bottom end rebuild need opinions

[davidvtec]

I have a complete k20a JDM engine with a knocking bottom end.

I also have a k24a3 block that has bad compression.

What I had planned in mind was to get new pistons and rods for the bottom end and slap the the k20a head.

I am trying to gather information and noticed people on k20a.org are suggesting to run either supertech, wiseco but recommends mahle Pistons.
With 12.5:1 compression 88mm.
Either oem or Cunningham rods.

Would like to know what are your thoughts and what are you guys out there are running?

Cheers guys!

My 2 cents -

Service head and block, get the crank checked etc etc.

Supertech head combo wombo
Good piston and rod combo - stock compression forged of course
ARP head studs
toda chain tensioner
renew the rest with oem.
K20 oil pump

Rest the money i'd spend on turbo, fuel needs , manifolds, cooling and braking in time.

But I've feeling your gonna make mistake and stay NA

In dat case Imma ask you wat cams you gonna run for compression dat high? Is this your daily? Is reliability going to be an issue? Have you budgeted an ecu?

[amant02]

Have you spoken to a shop dat builds Honda engines?

I would start there 1st buddy. if you gonna overbore the block and go 12:5:1 your talking about sick NA build which will cost you thru the arse for shit output compared to turbo counterpart, specially if not done properly.

You better speaks to the pro's cos this may end up costing you alot.

You could PM traders here JDMyard, Sleeping Performance. Both had been very helpful when I wanted to build my kseries.

[davidvtec]

Nah not yet.
If it's thru the arse then I'll should just make it basic.
Just slap the head on with another bottom end.

[amant02]

no rebuild the broken k24 you have. Do it properly.

Just speak to builders and they will let you know far your budget can carry.

I would do pistons atleast if you were opening the block.

I think the oem cu2 pistons will work offering good compression at oem quality.

get 4 piston racing to build you a motor, get it shipped over, get Adrian at sas to tune it


and enjoy your 300+ naturally aspirated horseies on 98

hehe

oh and do yourself a massive favor- don't listen to amant, he is the village idiot.

Stock comp on a 'built' NA motor?
Stock rods as well?



A cheaper alternative would be to just find another k24, stick your current k20a head on and retune
Or find another k24 and get a 163 with appropriate cams/ valvetrain and tune on e85, amazing how much the americans are makeing with seemingly simple setups.

Talk to the pros and read up on k20a.org

Just remember, the boltons to make it all work together will set you back a good chunk as well, don't just budget for the motor itself.

Stock rods, TSX pistons, Supertech valves k20 head. $$$ add up quickly and then a decent cam

[Stevil]

Stock k24 and turbo is cheaper lol
