im lookin to find the K20A2 and the k24 bottom end engine specs
rod length
bore
stroke
valve sizes

and that kinda cool guy stuff

Anyone??
yes i did search

I can fill in a few of these anyway.

K20a2
Bore: 86mm
Stroke: 86mm
Deck height: 212mm
Rod length: 139mm
Intake Valve: 35.15mm
Exhaust Valve: 30.15mm
Compression Ratio: 11:1
Displacement: 1998cc
Power (bhp@rpm): 200@7000
Torque (ft/lbs@rpm): 142@6000

K24
Bore: 87mm
Stroke: 99mm
Compression Ratio: 9.6:1
Displacement: 2354cc
Power (bhp@rpm): 160@6000
Torque (ft/lbs@rpm): 162@3600

 

r/s ratio on the k24 is in the low 1.5's
welcome to non-rev happy land.
it'll make killer torque everywhere, but have f1 style piston speeds if you rev it to 8000 rpm.
do a short runner intake manifold to move the powerband up on the k24 if you are going all-motor.

 

Good to see you in here Dave.

Which companies, if any, are making bottom end parts for the k24?

 

that would be my next Q

 

and ...im wondering if we could use prelude pistons in a sleeved block

 

the ls's r/s is just as bad and people rev the **** out of them. at least i did

 

Bad or not bad. LSVtec revved like a ****, and i have seen people rev those things like no bodys business.

I have seen people use Prelude pistons in Sleeved Bseries. If im not mistaken, Cheetah did this.

Might be able to, just wonder if the makeup of the piston is the same. Hopefully the compression with the h22 wouldnt be too high or low. Dome height hopefully wont be a problem.

 

aebs has sleeves for the k24 already

 

I know FF geoff has talked of a drag racer or 2 using a K24 in a Insight. Wonder if this dragracer is using aftermarket parts in the bottom end, or if Full race or any other companies might be making pistons or rods for the k24.

 

hytech is making some stuff:
3 sets of street cams
1 set of drag cams
1 set of road race cams
multiple compression levels from 9 to 1 to 14 to 1
stainless valves
Ti retainers
valve springs
CAI
New intake manifold
50 mm individual throttle bodies
Multiple exhaust headers
Exhaust Systems
Ported Cylinder heads
Carrillo Rods in 3 different lengths
2.3 liter crankshafts
ECU reflashes
And a few other surprises.

 

Hopefully this will be for the a3 and k24 heads as well as the a2 head. Hopefully more support will grow for the EP and 2.4 with their Single stage vtec

A few companies are making parts to test on our k24 as we speak. The cams should be ready now!!

If anyone doesn't believe in the K24, our car put down 170hp 150ft-lbs with a STOCK k24 with bolt-ons......that's 150ft-lbs from 2800 to 5500rpms. On the 65 shot it put down 225hp 246ft-lbs.

 

Am I the only one that's more interested in the k20 than the k24? Both are kewl though.

 

i am for sure... k20a all the way

 

Wonder what the difference is, ecu? There cant be that many differences

So does the K20a2.

I just like the geometry of the K20 better I guess.

 

Golden Eagle can do sleeves and deckplates for K-series..

Get a K24 block, sleeve, deckplate, and build it. Stock 99mm crank.

88mm bore x 99mm stroke = 2409cc. That could rev to 9,500+rpms.

With a proper flowing ported heads, huge cams and valvetrain, itb's, lots of tuning, high compression, im sure people will be making 330-350+whp all motor eventually. That will be the day.

 

That 300+ would be o so great

 

That'd be one tall motor. Piston speed would be crazy with 99mm stroke at 9500rpm.

 

Does anyone know what the maximum bore for a F/I K24 is?

Also, with Todas VTC Killer cam gears (and necessary ECU junk) is it just like adjusting the timeing on a B series?

Is it just me or did that make absolutely no sense whatsoever to someone else too?

 

I've read on here that the max bore for a N/A K24 is like 91mm or something, so what is the max bore for F/I?

Toda's VTC Killer cam gears....They get rid of the Variable Valve Timing and the stock ECu won't work with them. When using these, is it just like cam gears on a B series when tuning and stuff (as VVT is removed)?

 

Guess it was just me. I don't know enough about the K24 to intelligently contribute.

 

I'm just wondering right now, no project engine sitting in my garage so just as long as its close to the real answer.
