(if this in the wrong place i apologize, i could not find a place to post this that seemed liek it would apply)
Ok so, i am starting a "long term" build, prbly gonna take a few years but i have got some decent cash right now.
I have my shell.

now this car is gonna be DD when it is done BUT also tracked Heavily.
I will say i am quite aware of the abuse im gonna put on it and the comfort i will have for DD. i have accepted that and put it behind me.
Now that, that is out of the way. I need some input of which direction to go with engine and tranny.
I have an opportunity to go with a k20r OR Go with a b16a gen 2.
the K20 will be N/a for now OR Turbo the b16.

i have about 6000$ right now that will get me the k20 and some bit of the conversion.
or go with the b16 (which i already have) and build it for a turbo.

i plan on circuit tracking this, not drag to be clear. money wise, i am content with spending the money and doing it right. this project i don't wanna cheap out, this is my baby. i realize this will take some time, but i do wan to have a direction set out.

i have been researching like crazy over this but would now like some feedback if i may kindly ask for some. i have my thoughts but would greatly appreciate some opinions and view points from you guys.

i've gone through a million different threds reading about k20 vs b16 vs b18. the thing i noticed was money, was always the number one concern, that i dont care about. hard work and lots of time will bring the reward. so again that aside. my question being

6000$ to start, which build direction
N/A k20
turbo b16
in the end, what has the potential in your opinion(s) for the overall dominating engine.

reason why i ask is i see N/A K20's mopping the floor against turbo'd sooby's evo's blah blah.

turbo'd b16's can do that too BUT what keeps crossing my mind is a turbo'd K20 should theoretically waste and put to shame my previous statement??

i dunno. just need some feedback.

Why stuck on just those two set-ups? Also what do you mean by tracked, drag, circuit, autoXX?? RULES come into play rather then your set-up.

K20 is way over hyped for the price but street credibility thinks otherwise.
Only thing I would use from a b16 is possibly the head casting.

blazzer

that kind ^^

which i understand and have my build, being built according to rules and the class i wanna race. partly why i have to choose these engines.


well the k20 seems decnt for the price i can get it at, to be clear it is not a k20 from an rsx, this k20 is coming from an FD2.
and the b16 i already have and know the condition it is in.
so i can use it or sell it for the build fund.

my quick sorta thoughts is to sell it as the k20 seems to have more potential in the long run... but i also dont wanna be biased about it

You're going to be REALLY stretching your 6K getting a k20 in the k-pro alone is 800$ add more if you want a PRB ECU, why not a k24 with a k20z3 head. arguably you could sell the b16 and it's related parts and turn the 6 k to maybe 7.5 then you'd be ok. The thing is I see no budget set aside for suspension/aero items(splitter rear diffuser) your b16 could be turbo'd for 3.5K or so then dump the rest into suspension if this car will be for time attack.


most of my money went into suspension aero/cage/tires all I have is a 248 B20V lol but I can still post up better lap times then some of friends turbo'd/k swapped cars with basic suspension.

yea.. that i what i kinda figured with the k20, the engine, tranny, stock ecu, axles,etc. is running me at about 4800$

well that i just it, why i am having issues deciding. partly i freakin love the response and feel of an N/A engine. but for that money, turbo my b16... what kinda results am i gonna get from that for a track car, that i could or could not from an N/A K20....?

suspension i already have. well... some of it. i have dampers and coil's adn rear LCA's right now. i bought the damper kit a year ago, got sidetracked with life and am finally starting my build.

well, im tryign to stay away from hybrids. and TBH the k24/k20 frank swap has tunred me off a lot. the biggest thing when researching it was the debate about piston speed due to the longer stroke. applying my build to track-circuit racing. figured the higher revving option was probably a good idea with "some what" less wear vs the k24/k20 wear due to stroke length.

the suspension i have ATM are function 7 bearing LCA's and will be sitting on tein "super racing" dampers.

i do plan on aero/cage/tires as well. i just need to get my engine direction figured out first then i can concentrate on everything else, as this engine decision is playing boggle with my brain

Sorry I didn't notice when you stated about circuit before.

K20 is nice, and a great platform if you have the funds but you stated for NA.

B16 boosted with all above suspension etc will be a sweet ride all around for probably half the cost once finished. This is a VERY hard debate and all depends what you want to do. NA or Turbo??? big difference in platforms

blazzer

It's all good man

yea tell me about it hahha, been debating so hard, back and forth in my head im getting headaches over it.

i keep thinking track, so N/A but the money to potential of a turbo b16 vs a N/A k20 is equal for decent money. both engines are sitting on the same suspension setup in theory.

the money like said does not really bother me, my logic is work hard for the money and do things right, even if it takes a little longer, it is worth it to me.

my issue is the actual build, im leaning k20, partly becasue well N/A reading about the specs of the k20 vs a b16, better flowing, less friction. chain belt is good, but i like the timing belt on a b16 due to the lack of vibration when compared to a chain belt..

guess im looking at every angle.
the turbo b16 vs an n/a k20. if the b16 has to be turbo'd to be on par with a k20..., then you thoughts on this, but would not the k20 be the better platform to choose for circuit? in the nutshell?

ej1b18c1

If MONEY wasn't an issue for me, k20 would've been #1 choice right off the bat VS a b16.

k20r would be WAY better platform and the b16 turbo could possibly give you more traction issues out of corners depending on level of boost/boost control by gear etc.. blah blah blah

k20 would take my vote if someone said pick what you want don't look at the price tag.

blazzer

i did not think about it like that... given e more to think about...

hope more ppl post up too, curious what other's think... haha i am leaning k20r. think im falling in love

doctorake

K24, then build it out later.

blazzer

My other Question if anyone knows, ( i searched with little answer) the engine rotation, because it is spinning "the right way" is this going to effect wheel handeling,traction, grip?

rather then have that inertia from the opposite spinning engine of a b16, the k20 spinning with the inertia/momentum of the car. i feel like this would not help the car slow down when entering corners and cause less grip?
basically causing slow transitional understeer? or is this incorrect?

read read read!!

whether it being a k24 hybrid or k24 block and head. no k24 period.

If money isn't an issue it's really just preference. With enough money you can make 700whp with a d16z6. Hands down though the k20r is faster, torque alone is close to 100 lbs more

Schister66

With $6k to spend, I would build/sleeve the B16 and boost it. That's more than enough money to build a proper turbo setup that will stand up against the rigors of circuit racing. If you want more opinions regarding this option, start a new thread in the Forced Induction forum...there are several members who circuit race turbo B series and i'm sure they'd be happy to give advice

uhhmaysing

If I had the choice I would go with K20 as well. The possibilities of the motor are far superior than that of the b16. Torque is exponentially higher than a b16, and you don't have to worry about building boost to power through a corner. And with boost always comes problems, a N/A k series motor will redline all day and be happy about it. But I also would like to say nothing is as fun as a boosted honda, JS.
