( no BS answers need facts )<U></U>

I would like to know how heavy is the h22a1 motor compared to the k20.
On paper the difference are not that apparent, sure the k20 flows a lot more
then the h22 but I remember hearing “ there is no replacement for displacement”.

1) Would a 4th vtec car be able to beat an RSX type S ?

2) How heavy is the h22a1 motor compared to the k20 ?

13) What are the advantages of the K20 , and disadvantages . Same for the h22 ?

4) Is all this hype about the k20 misleading and pure BS ?

5) The RSX is no skinny car itself, what is the total difference in weight and dose it make a noticeable difference ?

Mature , coherent answers PLEASE <U></U>

 

The k20 is the next best motor to swap. Its got a 6 spd tranny. The amout of hp you can squeeze out of it with just bolt ons and tuning is unbelievable. This motor is new honda technology and the h22 is out of date. This motor will cost alot more then the h22 to get everything going from swap to bolt on and aftermarket parts.I know the k20 is a lot lighter then the h22.

1. no if both drivers were competent.
2. the b-series motors are heavier than the k20 so i would be guessing it's about 80-100 lbs lighter.
3. k20a is awesome for bolt on power (n/a), k20a2/3 is good for boost, and the h22 with its large displacement is also good for boost.
4. no, the new series of honda motors is amazing
5. actually the rsx is skinny, it's only about 45lbs (i believe) heavier than the dc2. you're talking about a 200 lb difference between a prelude and the rsx.

preludes need the torque, you'll have to put a k24a in there and then swap the head out for a k20a for better airflow.

 

K20 swaps are going to be on the increase as mounts and wiring harnesses become more available. H22A engines are roughly half the price of the K20 type-S engines unless you find a really good deal.

 

a testament to the new engine, a large number of Honda challenge H1 hybrids have swapped out their built b18c5's for K20's. lighter, more responsive to mods, and probably the best engine honda makes.

 

I have raced someone I know a couple of times with a brand new K20 and even when my car is running bad I still manage to beat him. He dynoed at 169 recently too. I think that if you have the money to put one into a civic it's a good idea, but if you have a lude it would be less of a headache and a cleaner swap over all. Good luck... of and anyone know the actual curb weight of an rsk with a k20? My lude weighed in at 2600 even with no gas...


Check the offical prelude video thread...

I, romped on a RSX type S in my stocked out 4th gen h22a1 lude. He had at least an exaust don't know what else. I'd say the H22 is definitely a lot better. I think OBD1 is the best vtec around.

 

k series = 200 WHP with simple boltons/reflash ecu

h series = 200 WHP needs cams (or in Corey's case SMSP but isnt common)

I'm a bit old school so I'll stick with the h22a1!! haha, but really, there has been more success stories behind the h series engines so maybe that's a better way to go! But I wouldn't write off the K's yet. They are newer technology so give it time and I bet it will surpass the h series eventually.

not true look at COrey our forum modorator, he is well over 200whp and has bolt ons and no cams.

also i think the K series come with a 11:1 compression ratio too. give me an 11:1 cr and simple bolt ons and i bet i could hit 200whp.

im not arguing that the k series isn't sick, but don't doubt the H

 

Im sure the K series have tons of potential, but like someone else said, due to lack of parts i dont think its the best decision. Most people are trying to get the most bang for their buck, and h22 swap costs half as much, whats the point? Im sure any K series part that is out so far costs a freakin arm and a leg to get. Most H parts are more expensive than B. I love my H22

 

ha.

k series in a prelude.

cha CHING! $$$

most arent willing to even spend that much in total mods on there cars.

for now, H series is the only way to go.

but give it 3-5 years and k series will hold a permenany fixture for all hybrids.

Yeah well he;s also running open header...

And in another thread corey said if there was a k20 mount kit for the prelude he'd have it in there (probably a K24)

Anyways K-series owns, there's really no discussion here.

 

yeah i should have re-edit my statement.... lemme do it right now.

h series = 200 whp not common with simple boltons

 

stock for stock they are VERY close. I have a friend with an RSX-S with same mods as me, just CAI and we've raced about a million times. It's really close. Up top (freeway) it's dead even, and whoever launches better wins from a stop. Also for the mag. racers, the times are really about the same as 5G ludes. 4G's are faster if both are stock.

They k20 will kill us once modded tho If me and my buddy both go get hondata, he'll walk me bad

 

JDM K20A Integra pulled my H22a CX

H22 = LT1
K20 = LS1

to put it simply

 

k20 is the future

Give me 11:1 compression and I'm sure my H22 will be around 215whp.. I don't quite run an open header, it does have a resonator in the exhaust =~P... Except to loose about 2-3hp with a full exhaust.. Other than that, I don't see why a street legal car can't reach my motor's level..

 

im surprised no one has mentioned anything on torque differences....

 

hahahah hilarious

 

Sorry guys, the K-series aftermarket has already outstripped the H in most areas.

And as far as torque goes, what little advantage the H has in displacement is more than made up for by variable cam phasing & a superior head design. Go with a 90.7 stroker, and even the displacement advantage is irrelevant.

K-series isn't the future - it's the present.

 

plus the k24 with k20a head is a crazy combo for power in torque and hp.

yeah im not saying that the K doesn't own but im just saying don't under estimate the H, i don't think its nessesary to get cams to hit 200whp on an H

there ya go, thanks corey i was waiting for you to chime in.

edit: speaking of tourque i am wondering what makes the k24 with the k20 head so rev friendly, i mean christ its got a 99mm storke.

check this thread https://honda-tech.com/zerothread?id=497180

reving to 8100 ! on 99mm stroke made 268wtq at 5500 and max 210 whp

edit : im a **** tard , that link above the car is supercharged, but still i can't under stand the reving of a 99mm storke that high
