is this even possible or has anyone does this before? it would be nice to slap a hybrid engine k20/24 into the ap1.

 

k20 tranny bolts up to a f20c with an adapter plate, so im sure u could use a f20 trans on a k20. but the k20 spins a different way than others so im not sure.

 

that would be a downgrade.

not to mention stupid... im sure if someone wanted to do it, it can easily happen.

 

Why would you want to is what I want to know?

Plus, you could not use the same transmission anyways... the K and F spin different directions, so you would have to do a full transplant... motor trans and all...

But before you decide to do that, give me your s2000 first, and let me drive it with the F....

Are you sure...I thought the K-series turned the "right" way.

K20 has more NA potential than the F20c for not much money. 230whp/160tq is not uncommon...but damn hard to get from an F20 or F22.

The K-series crankshaft rotates counter-clockwise like the F-series crankshaft.

you can easily achieve that from a f20c or f22c with bolts ons and a good tune...dont 4get the s2k has more of drivetrain loss

Hmmm...seems that 230 to the wheels is pretty hard to reach in an s2k. There is a huge thread on s2ki about how some folks are trying to do it...and it's tough. Definitely not able to reach that with just bolt ons...I've got quite a few bolt ons (toda header, T1R 63mm single, comptech CAI, Hondata IMG) and VAFC tuned by this forum's moderator and it's not even close to putting that to the wheels.

I had not heard that before...seems that it is pretty close to the usual 15-20%. 240hp crank...most cars pull between 190-205 whp stock. What's the drivetrain loss on an RSX-S?

 

I remember reading how one of the biggest difficulties with a k20 is the mounting points on the block itself make it a pita even with custom mounts. The question is, does the head fit on the block

For everyone that thinks the k20 is a down grade, you couldnt be more wrong. Those engines are so potent in stock form, not to mention with i-vtec and vtc you get incredibly good torque bands for a n/a motor.

K20A head flows 310-315 cfm on intake at .5" lift
F20c Head flows 320 cfm on intake at .5" lift
The only real difference in the K series and F series is the ivtec

Now for those looking for the best of both worlds (have i vtec in you st2k)
Head swap is being developed at our shop
The head is actually a bolt on, custom chain guides must be made, a few oil passages must be plugged and oil re routed (like ls vtec swaps), and custom chain covers must be made after that it is almost a 100% bolt up

We are in the slow progress of working out the bugs with this but we can assure it is fully possible to accomplish

k20z's put down around 170ish to the wheels bone stock, so drivetrain loss is pretty damn close compared to the s2000, and requires i/h/e + tune to reach 200whp, then from there your gonna need at the least a nice set of cams like some ips's still i give the k a lot of respect, gains most horsepower to mod out of any honda motor.... but i think the f20 or f22 is a better starting point...

I'm not the one developing the kit, you'll have to PM JG-Fabrications.

 

thanx, just intrested to see how much it would be....there are adapter plates for everything

 

interesting tread

Ill never understand why people want to put a FWD platform motor into a RWD platform car.

k20 motor is a good swap for integras and hatches, not the s2000 If you want to get creative, drop an s15 or 2jz in the s2000

it's because the k20 head, give more power, everyone want to power

for the price of the k20 head and the kit you can just get cams, valve train, and pistons for the f20c

yeah but you still having no I-vtec

i-vtec give a wonderfull powerband

so, you will be making more power which is why you said to slap on the k20 head in your previous post.

k20 head, pistons, cams,valves, .....

 

f20c, high comp pistons, brian crower stage 3 cams

keep the k20 head on a k
