My FA5 K24 build

I figured I probably have enough to get this thing rolling finally.

Bought the car up November 2011 after I decided my CTS needed more work than was worth doing.
*Edit*
Here's the CTS that the Civic replaced. 03 V6 5spd manual, tan leather, premium package. It only had a few minor things on it, Hotchkis suspension, custom intake, wheels, and decent system with JL amps/speakers.


Here's how she looked when I bought her.



I've only done a few things while saving for the K24 build. I picked up a flashpro, and an AEM CAI used for very inexpensive. Tinted windows and put a stereo in.





Here is the bone stock and after the intake and a minor tune. This dyno isn't very kind, but as we all know, repeatability is what's important rather than an absolute number.



Here is the K24 I purchased to use as the base for my build.


Got bored one day and polished the timing cover


Piston/rod combo


Supertech valvetrain parts


After assembling the block, I discovered that the rod bolts hit the girdle on cyl 1 and 4, so I had to tear it all back apart.


After grinding


I was also unhappy with how the block looked, so I decided to paint it as well.


After sandblasting






During painting


After assembly


While trying to install the oil cooler, I realized the K24A1 block was not drilled for running it the factory way. I decided I wanted to use what I had rather than buy more parts, so here's what I did.

Here you can see the hole isn't drilled out for the coolant pipe, nor the hole for the flange that holds it in place.


I drilled the larger hole and then the small one. Lastly I tapped the hole to accept the 6x1.5 (I think that's what size it was...) bolt to hold the water pipe in place.





This is basically where the engine sits now.


I did install the Invidia q300 when it arrived.


I'll try and keep this updated as I move further through the build. Hopefully within a few weeks I'll have the rest of the parts I need to get it completed. :fkya:

Here is a build list:
K24A1 block/crank
K20Z3 head
12.5:1 Supertech pistons
Generic h-beam rods (I know...)
ACL race bearings
Supertech springs/retainers/seats/keepers
K20A2 oil pump
RBC intake manifold
J35 TB (64.6mm)
Thermal gaskets for TB and IM
PLM header
Invidia q300 exhaust
Flashpro
Crower stage 2 cams (or SVM if they ever arrive)

Still need:
RDX injectors
Luck
Tuning
Time to finish and install!

Awesome bulid. Im doing a similar build with the exception of 12.5 compression pistons.

are you running on pump gas? I was planing on doing 12.0 so I wont run it so close to the edge.

Great build btw It looks Amazing

I found something else for the oil cooler on 8thcivic.

S2000 fitting (I don't remember part # ) that will bolt right into the block heater hole. This way you don't have to drill the whole in the front. You just need to take off the plug.

Yeah, I saw that as well, but I decided to use what I had instead of spending more $$. Plus I like the oem look, and it wasn't really that hard to drill 2 holes and tap one of them.

The initial plan is for pump gas, if I'm unable to get the tune where I want it, then I'll have to switch to something else. I'm really hoping I can run it on pump gas as this is my daily. In the grand scheme of things, I probably should have gone 11.5:1 or 12.0:1, but with my altitude fighting me, I decided to push the limits.

What's your p2w clearances look like with Supertech pistons? Any piston slap on cold days?
Here is what I figured when I was doing the ring gaps
With my craptastic measurements, roughly .0025, does that sound right? My snap gauge for the bore is pretty lousy.
As far as piston slap, I'll have to wait and see as the engine isn't quite done yet. I think I should be good though.

I wanted Supertech pistons but 12.5:1 sounds too much for 91 pump gas. I might go with CP 11.5:1 ... I have no idea yet.
I think I'll be pushing it a bit using 12.5 with mine on 91 but hopefully coating the pistons will help keep down detonation with out pulling too much timing.

Updates
Got the new water pump installed as well as the cams. Just finished initial adjustment of the valve lash as well. Up next will be timing cover and oil pan install.

Thanks for all the compliments. I'm trying to figure out which crank trigger wheel I need to use if anyone can shed some light...
