[JDM K20 Coupe]

thats rite i want to put over 300 hp to the ground with a k-series. i have talked to several companis and they say its not possible. i want to prove them wrong. i have a EK coupe with full interior and i want to daily drive this motor. any sugestions guys?

Wait for a little while for all the good parts to be mass produced

Obviously your talkin to the wrong companies...how streetable it'll be I don't know but its certainly capable.

I can give you a few ideas...

block - sleeve that shit and bore it as big as possible. Forged pistons with a grip of compression (I'd go with CP but that's just a personal preference). Maybe an S2000 crank (yes it's possible I've seen it) for a little more stroke. Some strong (and light) rods. Then of course all the typical block prep and balancing of rotating assembly.

head - I'd start out with a really good valve job and the best/biggest cams and valvetrain you can get. Dyno the motor with the stock ports before you have the head ported so you can dyno it again afterwards to quantify whatever gains you might get from porting.

Intake - TWM itbs

Exhaust - whatever header floats your boat theres a few people making nice ones...

And then you're gonna need a shitload of tuning so of course KPRO or AEM EMS is a must. Just keep tuning it, you might have to try a few different cams too. If you can't get 300 with this you should at least be able to get close.

I'd suggest calling R&D they build some pretty kickass motors...

First of all, thanks for posting this topic. It can be done and ti has been done. Drag racing, street racing and only a few people with it is the main reasons why the recipe it is not know.

The recipe consists of k24a sleeved block with aftermartket rods, pistons, stock crank, and a head with bigger valves, ITBS (port and polished as well)

The right combination has the potential to yiled this kind of power.

Crower, IPS K2 and future cams from skunk2 should be able to do it. ( I don't think TODA can do it right now, maybe in the future)

There are a few people on this board that can really help you on this. Give it some time and I am sure they will chime in and tell you what they think. Also asking the right questions is important. Noone is going to give you a 100% list of what parts to buy to achieve your goal... At least not now... People are making good money building these motors and they are not going to be posting that kind of info.

One of the reasons I made this website is to share info everytime I mentioned, I kept reading all these negative remarks from honda people that cannot imagine a world withiout B series... Well, I can.

And when dynojets spit out 300whp dynos in all motor setups, running pump gas, then they will have another excuse....

I hope 2005, brings happiness to you guys, health to you and your family and may the people affected by the recent disaster recover as soos as they can.

300hp on a K motor is totally doable.

Theres plenty of room to work with on the K20.

1. Bigger Bore
2. Higher compression/custom Pistons
3. Camshafts
4. Headwork
5. Intake manifold/ITBs
6. Engine Management

and if you want to take it to the next level
7. Custom Crank/Stroke, etc

thanks guys now atleast im starting to head in the rite direction. oh, to the person to say call r&d dyno because the biuld some sick ass motors well i did and they told me it wasnt possible

I dont know why they say that. When B-series are already making over 300hp to the wheels.

me either but thats what they told me. does anybody know of any other companies out there making cams for it yet?

 

[memphiss13]

exactly how big can you go with the bore for a street k series? i remember pacman having 2.7L in his sig on HT at one time. anybody done this yet and is that streetable? that would be a torque monster.

how nessisary is sleeving the block? im planning a K24/20A2 hybrid with up to 280whp, will a blockguard do the trick? or do i have to go big-bore?

i know the larger the bore you go the more prone the rods will be to breaking under RPM, since they will be heavier and acellerating much quicker

sleeves = necessary if you expect to make that much power all motor.

the second statement is not really true but I don't feel like explaining why right now. I'll chime in with an explanation tomorrow AM.

I think that if you guys are expecting to build motors that are gonna make this much power you really need to be talking to/working with some experienced, reputable engine builders...

how so?

bore width has nothing to do with piston acceleration, that’s purely down to stroke.

Only downer with running larger bores is the pistons will be bigger (thus potentially heavier), and the rods may also have to be heavier to cope with the increased loads.

That said, the bigger the better in real terms, I guess if you go with Darton or the like, you limit is ~89mm or so?

A little of topic but what's the most you can get out of a k20a without boring it out, but with everything else, i.e head porting,raised compression(13:0:1 preferebly), TWM'sITB's,BIG cams, I/H/E,K-pro etc????????

 

[non vtec]

I will let you know what a stock K20A pulls with all the bolt ons next week... I am off to the dyno with my DTR header set-up..

I can't believe no one had said it before this guy - but of course K-Pro!

 

[non vtec]

You would be probably be suprised to know that unless Norris runs a K-Pro NO K-series running under 12's is running a Hondata....

do you mean UNLESS or EXCEPT?

Good,Good, but what do you think a eg with the setup I described specifically would run??? WHP and TQ???? 1/4 on street tires and slicks????[/b]
