Buddy of mine wanted to know what the best k series motor to get. He wants to do a k series swap and is looking to get the type r k20a. Told him if he gets that motor to just do the swap and have fun with it and and to not "fully rebuild it" told him it would be a waste of money and time cause it's already pretty much built it's a type r k series. I'm thinking he should do a k24a2, it's not that expensive and I'm hearing there's a lot of parts for that motor specially to be "fully built" NA. I think it's worth the money to rebuild the k24a2 to give it more power so he can stay NA What do you guys think? Is the k24a2 the best route when it comes to a K series rebuild for NA ?

all depends on what he wants to do. If he wants a fun stock motor, k24a2 is the way to go. they can make good power with an RBC, cams and Header. for minor mods.

As far as a built motor, what do you mean? new rods and pistons? sleeved? ported head? cams? valve train?

BrianB16A2

I told him if he wants sumn stock to get the k20a type r since it's a type r and is pretty much built.

As for the k24a2 told him if he wants sumn to "fully build" NA to go this route makes more sense to me anyway. I'd leave it stock if I got the type r k series

Yes when I say building this motor I mean cams, pistons, valve train, intake mani n TB, rods, bore etc.

How much would a k swap b including the motor
I'm thinking 8-10k?

k20buildinprogress

A type R(k20a motor) is no where close to "built." I has a slightly larger cam profile than the type s(k20a2)

For anything Naturally Aspirated I would go k24. If he is going to Built a motor, the starting motor doesn't matter. k24 block and crank and a k20 head, then buy parts accordingly to the desired function of the car.

If he wants to go forced induction(turbo, sc, nitrous) a k20 framed motor will do much better because you can rev them higher.

Never done a swap, building a sfwd dc5. you have have 8-10 grand in a "built" motor easily.

depends on chassis and how reliable you want it.

Theres cheap, fast and reliable. have you heard of this before? you can have cheap and fast, but it won't be reliable. you have have fast and reliable, but it won't be cheap. lastly, you have have cheap and reliable but it won't be fast. take your pick.

My stock k20a2 is awsome. :-)

BrianB16A2

I'm just helping him out and who knows I might want to do a k swap myself I just wanna make sure I can afford it. I want it reliable clean and done right. Noe half *** shyt.

I was told for a proper k swap it would be around 8-10k from what ive seen.

It's expensive but I can totally understand if I want it done right. You pay for what u get

I don't think the swap is as expensive as people think. It's the mounts, harness, k-pro, and extra swap parts that add up.

I gotta go with what's been said so far, go K24. If budget and street car are both in the same sentence, then there's no reason not to go K24. When searching for a car to buy, I drove an EG with a full K20A-R swap and then test drove my current K20/K24 and there wasn't a comparison torque wise. I think the added torque of the K24 really brings the car alive on the street. The only downfall is that you must use an RSX-S/DC5R or S2K oil pump to rev semi safely to 8k, so you lose the higher reving capability on the K24 due to added piston speed. Most K24 guys do an 87x99 12.5:1 build using Wiseco HD pistons and a set of light weight rods (Cunningham, Crower, K1, etc...). This will allow you to rev to 8k safely and some have taken theirs up to 8600rpms.

Just food for thought.

BrianB16A2

That's awesome bro
What do u consider "not that expensive?"

I can't afford it as of yet. I can get the
Motor for now but then It would just set me bak and would be sitting in my garage for months cause I'd be broke. In hearing 8-10k for everything.

If that's the case is just stick with a b series :/
As much as I'd like to get a k24 :/ or k20aR not sure which is better

D Grade

Well considering you can find complete heads for as little as $400.00, complete blocks for as little as $500.00, and tranny's as little as $600-700.00 (depending on which you go with), I'd say the potential cost difference isn't much over what you would be paying for a quality LEGIT B-Series motor. Like I mentioned, the real cost comes with the hardware needed for the swap, which is the mounts, harness, water necks, adaptors, etc...

EE2bitsk

the price isn't comparable to a b series at all.

speedjunkie_g35

K24a2. I have been debating on getting a k myself because my b will be boosted and FI classes are going to kick my butt. A k in NA classes are competitive. I originally wanted to get the k type r swap and just swap over a k24a2 bottom end but cost is the factor vs finding a k24a2 and a 6 speed. It will be costly enough just doing a k swap let alone two complete k motors(wouldnt want something already cracked open for reliability reasons when not rebuilding) so a k24a2 is stout enough when swapped into a ef/eg chassis. A head can always come down the road.

speedjunkie_g35

If you look at what it takes to get a b series competitive with a K in a NA situation, you would spend as much if not more as a k swap.

Knew a guy w/eg with a stock k24 bottom end, stock k20 head in the 230-240 whp range.

EE2bitsk

I'm talking stock vs stock

BrianB16A2

I'm seeing slot of people saying that it's cheaper to do a b swap. K is more expensive. I'm talking about a whole k swap (full)

I have a b16 in now and of course it would be easier to throw in another b series motor.

A k series I need mounts, axles, harness, clutch lines, fuel lines, etc.

The mounts come with the swap but I'm talking hasport.

Makes more sense to me to just swap for an itr than a k. It's cheaper

EE2bitsk

yea swap for swap, stock for stock the b will always be cheaper.
k series takes bolt ons better than b series.
it all depends what the owner wants.

D Grade

Of course it's not, you have mounts, harness, K Pro, all the crap I've been blabbering about in the previous posts. My statement was price vs price for a head, block, tranny. K Series isn't that much more, as I've said the bank breaker and price difference comes in the accessories needed.

Fully agreed. If you are running a B-Series, you will not compete with a K-Series 98% of the time unless you boost the B-Series. It's just a fact. Also I made 240whp/190 ft lbs on a bone stock internal'd K20/K24 setup with an untouched RBC IM, crappy header, and pressbent 3" exhaust. Given history and YouTube, that's good for high-mid 11's.

My b16b swap = 5 grand

My k20 swap = 10 grand

You guys can do the math lol

BrianB16A2

^^^ exactly lol like i said I can afford the k series motor. I'm just gonna need more money for the swap cause the shyt I gotta buy for it. Shyt isn't cheap

Think I'm just gonna stick with the itr swap and get done mounts for it and an s300 etc.
then boost it later not sure as of yet for the boost

egvera89

you can do a k24a2 stock swap and get around 230-240 depending on the bolt ons and tuner. It's a good motor as well. Also the long blocks range in price from 1200-1800 and then a 6 speed transmission would range from 800-1300. a kpro is 1000 so those are the heavy hitters. everything else is actually not that bad in price. with some good searching you can do a k series swap for 5k.

BrianB16A2

Nice that's what I'm gonna do get a k24a2 long block. Found one on HMO for 1800 plus shipping and handling :/ the rsx type s tranny I'm having trouble finding for 800-1300 I don't need k pro

Found a swap package from k tuned for 3400 everything I'll need and shifter

egvera89

Yea nice they have that package deal I forgot about. Its not that bad of a deal, Good luck with getting the k swap

BrianB16A2

Yea man super glad they had that cause I wouldn't know wtf to get. It's cheaper to do that than to buy everything separate. Need a Fukin eg subframe (cross member). The long block and tranny isn't really that much it's the parts you need for it is what makes a dent in ur wallet. I will get this swap done tho fo sho and thx bro I'll keep u updated

doood

You need kpro. Maybe not right off the bat, but you need it.

X2 on kpro

BrianB16A2

Why do I need it if they sale a bypass immobilizer ?
