General specs:
K24A4 block deburred, sanded
99mm OEM crank (to be polished)
China forged rods
OEM bearings
87.5mm Wiseco pistons
12ish:1 compression ratio
K20A2 oil cooler
Baffled K20A oil pan (no pic yet)
K20A2 oil pump w/ radiused galleys
K20A2 head w/ new guides and valve job.
OEM valves
Supertech springs and retainers.
JDM ITR cams for initial startup and IPS 8620 K2 cams later
PRC (JDM ITR) intake manifold
50˚ VTC cam gear
New K20Z top cam chain guide
RDX 410cc injectors
Tilton twin disk cerametalic clutch
Tilton 6 pound 4oz. flywheel
OEM NTS3 6-speed gearbox with LSD
Custom axles
Crappy 4-1 ram horn style header
2.25" mandrel bent exhaust (looking to install a custom 4-2-1 x 3" later)

The K20A2 head came off a hydrolocked 2002 longblock that I picked up locally for $350. The exhaust guides were shot so after buying a bunch of OEM replacement parts from Bert-O it's got a valvejob and new guides. While the head was apart we knocked off a couple highspots but it's unported otherwsise.

The K24 shortblock was bought from 6spd_EK at a pretty damn good price even shipped cross-country; about $400 less than I could find locally.

There are some space limitations and as such we'll be limited to a smaller selection of manifolds. The RBC intake manifold won't fit without extensive modification so we'll be using the PRC until we deem that some other testing is necessary. I've been offered the Hytec casting for testing but first things first.

And the usual pictures:
Weird K24 oil pump/balance shaft assembly. This engine is pretty clean.

Crank exposed

Lots of extra parts waiting to be assembled.

Flat lapping the lower cassette

Checking that the heating process for the valve guide installation did not warp the head. It's flat within .0005". God, I love precision inspection tools. :drool:

Head cleaned up and inspected for proper valve guide installation height.

New OEM dual valve spring seats since they were scavenged for another K20A build.

Valves lubed and installed

DIY valve spring compressor

Valve train assembled. We left a couple pieces uninstalled for partial assembly and clearance checking.

K2 cams

Tilton FW/Clutch packaage (it's 20 pounds lighter than an OEM H22 assembly )

OEM 62mm throttlebody, tapered. Nothing important just a little attention to detail. If I get a chance I'll bore out the IM for a 64-66mm TB. I just need the time and motivation.

Before and after shots of the pistons on the exhaust side. Needed a little cleaning up.

I'm supposed to pick up the block today and then hopefully we can get some things sorted out. I'll be chucking up the crank for some polishing on the rod and main journals soon. I'll take pics as necessary and post them up since that's what the All Motor Forum loves.

That's all for now.

Looking good pirate i know you will keep us updating so good luck on everything. I'm sure it will be all you wanted it to be.

what do you plan on using for engine management? i'm guessing kpro...

Anyway, I digress. I uploaded some pics of the pistons that needed deburring.

Look forward to the end result.

it's the best k series top cam chain guide made to date. in most cases it might be overkill, but an anal person like me and less than 20 bucks, i bought one from the dealer for my build. it covers more area than other k series chain guides.
there's a thread in k20a.org about it.

What Evil Ryu said. It's just more substantial. It might help keep the timing chain on track if something goes pear-shaped. It's like $10 too so can't be all bad.

I have not made much progress since the last post. the lathe at work is occupied with real parts and the other lathes are either too big or too small to hold the crank. The shop also hasn't finished the block yet for one reason or another. I guess people are starting to anticipate race season and I think they're busy.

If you want the ability to tune VTC without running Hondata, look into a DTA S60-Pro. Priced roughly the same, but with more features, like a CAN +/- if you ever want to run an external datalogger like an A.I.M., and additional outputs/inputs + functional traction control.

Looks good so far

Why not try the OEM TSX Manifold, a guy on K20a.org had one that was modified by himself and made awsome power in the meaty part of his powerband.

That's neat, thanks for the link. I'll read up about it more. Those pesky English companies being all original... Unfortunate for me my Kpro is already paid for.

I'm going to use the PRC due to availability (read: I have it) and also due to space constraints. I currently have an RBC installed but with the K24's extra deck height I'll either have to hack on the RBC, redesign the engine mounts or try another manifold. So PRC it is. I can change it all around later once everything's built and broken in. If I get the power I want then I'll just leave it alone.

Anyone want a nice RBC intake manifold cut to fit a K20A? I'll have one for sale soon.

Thanks for the positive comments.

Sell it. The beauty of electronics is that they do not depreciate in value over time as much as a mechanical part.

There are a few Norma race cars that use K20's with DTA systems. They are a very desirable system for endurance racing due to their weatherproofing and shockproof boards.

I may if you come around to selling it. Ive got a PRC manifold on my K24A2 right now. What kinda fitment issues?
I'm mostly worried about it hitting my monster radiator(thing is freekin huge).

Although, i am very happy with the PRC mani, i was able to put out 230/185 with it(all stock except the usual cheap bolt-ons) and more left. So perhaps you'll hit your goals with that thing anyways. The plenum is a little small perhaps for the upper 200's lower 3's but the runner length is about spot on.

Nice project man

for the k20 oil cooler - not sure if you know this, you can use a s2000 part (fitting) to make it bolt up (no machining of the block - like previously thought)

part 11107-PT2-000 ... only problem is its on back order everywhere

Perhaps in the future I'll do that, otherwise it's an unnecessary complication right now.

I don't have an Integra so I don't know if your fitment issues will be the same as mine. I suspect that if anyone else has a K24 in a Teg you should ask them about their experience.

IlA friend of mine and I have both experiance tilton clutch failures. Same clutch you have both of us are k turbo cars but the inner splines have ripped off the clutch packs. I am a hair over 550,

I suppose it's a risk I'll have to take. I don't anticipate getting much over 200wtq so the torque load on the splines should be much less than your turbo build. I also don't plan to do many drag launches either, just spirited driving.

If you have not been tracking your twin disk does that mean you've been driving it around on the street? If so what's the engagement like? Is it really harsh (on/off) or is it pretty easy to modulate? What throw out bearing have you got?

Yeah I tried to order that, but as you said it's on nation-wide back order. It would make some things a little easier but I can improvise or make my own out of aluminum if it comes down to it. I'd have to find the thread pitch and clean off the metric controls on the old manual lathe to cut metric threads...

I'm always up for a new challenge.

First, I am not fat enough to hold down 100 pounds on that unergonomic, short-ass lever and the attachment that rests on the retainer might mar the Supertech aluminum retainers.

My compressor cost me about 15 minutes of my time and a piece of scrap aluminum. I don't have to push or pull or lean on the damn thing either. I can go get a beer in mid-operation and come back at my liesure. It's so much better than the other tools I've used in the past.
