whats better, k20a or jap spec b18c

[cuongn]

just wondering before i do this project what would be the jap spec b18c be making at the wheels kw wise, and what would be the jap spec k20a be making at the wheels, does the b18c jap spec make 149kw at the engine, what would it be making atw, compare to the k20a, or the k20a would overall be a better performace base.

[bennjamin]

b18c JDM ITR = about 100-110kw ATW ,has 147kw/172NM torque.
K20a JDM would be about 120~kw ATW , has has 162kw/206NM torque.

apart from the quite noticeable price difference* the K20 would be the logical way to go for more performance in every way.





* a B18c in your car for example would be "about" $6-7k all up drive in drive out.
A K20a in your car would be "about" $15k all up drive in drive out

[chunky]

id go for the b series

[aowwllan]

same.. not a big fan of k series to be honest

[DreadAngel]

Psssh, work your B16A and save the money for a better car later on ;)

Psssh, work your B16A and save the money for a better car later on ;)

I agree. I am enjoying my B16 now and try to within budget make it faster. When i am ready(about 2-4yrs time), Upgrade to an STI and start the modding game again.

I love Honda, but theres no harm trying more cars and more powerful cars that can bring u to higher levels. (I noe a K20 EG can beat a stock STI, but STI has 280hp to begin with and $5k can release more power rather easily compared to N/A.)

Thats my opinion. However, I must stress that VTEC revs high and the top end is superior to any other engines that come stock. haha. Gd luck..

Back to thread topic, get a B18C if u have to.. $6-$7k is reasonable. Add another $15k to ur car present value, assuming Ek4($10k??), $25k can bring u places dude. 2003 WRX is yours straight up. haha. Enjoy and make ur choice carefully.

[SLOWEGG]

B18C with bolt ons + tune 120-125kw
K20A with bolt ons + tune 140-150kw

u have a good point but people need to understand that money put into a car is not an investment.

but knowing u have something special is different.

eg wid k series = animal !!!
even if u wouldnt get your money back in d end !!!! u had fun wid it, people respected u for it. u cant get that in a stock 2003 wrx.

but obvoisly everynoe thinks differently ... logically the best option for that money would be a wrx or sumthin but a car wid a k taht didnt cum wid a k is in my opinion better.

B18 + bolt ons = 12.9 (KRIS from melb)
K20 + bolt ons = 12.3 (Paul from QLD)
K24 + bolt ons = 12.2 (Yonas from India)

[SHOGUNOVDDRK]

to be honest it really depends on what car its going into, what the applications its going to be used for and most importantly BUDGET BUDGET BUDGET :p

If it were going into lets say a EF and you were going to be using it for the lovely twisties (come on who doesnt go for twisties) id say go for the B because of the weight difference (unless your planning to put her on a massive diet) and the fact that it is alot cheaper

If it were for the straight road then id say hell go for the K....(who needs turnability when youve got speed :cool:) plus your in it for the win :D

it all really depends what car its going in, what kind of suspension your going to be running and as stated above budget and most importantly FUNCTION

remember you also have to consider the fact that the K series ways a bit more then the B...not too sure on the exact weight but i read its a couple a hundred pounds

but then again you also have to think about the fact that the k series will probably achieve higher numbers with less modifying :zip: and pain

so wat would i pulling down the 400m if i just get drive in drive out k20

[JDM.Power]

so wat would i pulling down the 400m if i just get drive in drive out k20

depends on how you setup your car, the condition of the car and engine is, and your driving style.
with the right setup and good driving in the high-mid 12second.
with a OK driving style in the low to mid 13s

Yeah, if your not going to regret blowing a good 90% or more of the $$$ dropping a K20A or something like that then go for it, otherwise a B16A is already a better performer than most 1.6L, just I/H/E + Tune proven by countless others gets good results already, no need to go for others. If you want a B18C/K20A in your car say EG or EK, most chances are that someones already done it so buy it off them. Don't give me that load about but I want to do it myself. Unless you actually do almost everything yourself like Paul or Fatboyz or Ben, etc Save yourself the time, $$$ and energy and have it done for you already. Most of these cars are already modified, rarely do they stay stock B18C/K20A cause these people that can afford it blow even more $$$ on them.

The amount of $$$ some people blow, they could already get a few other crazy cars like GT-R, NSX, Supra, RX-7, etc...

[hunghing]

what abt the type s h22a
?

[SLOWEGG]

how about u tell us your budget?

[fatboyz39]

H22a type S rated at 220BHP same as JDM k20a motor.

if money ain't a problem, go for K. If on a budget go for B.

[EG5]

so wat would i pulling down the 400m if i just get drive in drive out k20

depending on car weigh , suspension set up , driver , tyres , tuning and alot of other factors

too easy to run 12s with everything set up right.

Just because I'm Paki, doesn't mean I stink.

PAKKI!

Also, vote for K series. ZOMG THE TORQUE RANGE AND PEAK POWER.
Makes me seriously moist.

[Fo55il]

wtf wid d paki jokes - leave us alone lol

.... in regards to the h22 s type converision? cheaper thatn the k series i presume ?

[DreadAngel]

H22 for sure cheaper than K20 ;)

vt1-r: Doing mods to your car would not bring the price of your car up to 25k.. your dreaming to sell an ek4 with a k series for 25k

B series = FUN :) the vtec is soo much funner and if your not aiming for a PB and just more power then go for the cheaper alternative. The EK4 is pretty heavy because of the sunroof so why not first look into removing
- sound deadening
- the sunroof mechanism and just put a manual one instead (moon roof only)
- rear seats + put in a space saver

[Fo55il]

just have 2 cars -

1 to look pretty in
2 for track use or wateva ue u may find for it ...

u could even buy a cxi n strip erthin out n k series it n then make it to look exactly like your ek4 .. only faster ...

lol

Dude, read what i have wrote again.

I said the budget to buy a B or K series and put it into an EG/Ek, say buying a K series, cost about $13-$15k installed etc. PLUS selling ur existing EK4/EG6 for $10k if gd condition.

THAT will make $25k=your K series budget+ your car value... That can lead to other choices. Thats all man.

[SHOGUNOVDDRK]

perhaps a plug would be more space/weight saving?

B18C = mucking around with stock turbo cars and small league V8s
K20A = mucking around with modified turbo cars and big league stock cars

[DreadAngel]

Or you can skip Hondas and go Nissan VG30, RB26 or Toyota 1JZ, 1.5JZ 2JZ :D

b18c with bolt-on $8-9k swap

[cuongn]

***kk how hard would a k20 turbo would go, u reckon they go into the 11"s or 10"s,
b18c jap spec, does 14,7 sec down the 400 , correct me if i'm wrong is that true, wat if u put that in a EK civic, would i get into the low 14"s or high 13"s

throw some points dis ways

[hinezz]

Or you can just go K20 turbo.
or K26 Turbo (k24 stroked to 2.6litre) ;)

[EGB18CT]

or k27! k series are just starting to peak, plus there should be far more to come out of them now that the competition is starting to hot up...
NA Kseries ftw!

[SLOWEGG]

or K26 Turbo (k24 stroked to 2.6litre) ;)

OR Dseries turbo :cool:

[cuongn]

has anyone in australia done a k20 turbo conversion yet

[DreadAngel]

More than likely someone has...

[SLOWEGG]

Turbo DC5, 220kw.

[aaronng]

I'm quite surprised that people are willing to further stroke the k24 to get a k26 or k27.

[fatboyz39]

why not? more displacement more power.

[EG5]

no replacement for displacement

more torque with a bigger displacement engine = more wheel spin power

The fastest street car fwd allmotor is running 2.6 K series motor , they will do 2.7 soon .

[aaronng]

The stroke of a stock k24a is already 99mm, that's why.

[EG5]

The stroke of a stock k24a is already 99mm, that's why.

Its not all about high RPM rev
On a K24A3 swap to EG/EK for example its not needed to rev that high like K20A to get the car moving.

If you want it to rev , proper built K24A with stroker kit can handle 9k rpm easy

[aaronng]

Most people are used to revving a Honda to 8000rpm. Would they be happy with just 7300-7500rpm even in their lightweight EG/EK?

[aaronng]

i wouldnt.. just the sound of the motor going crazy is what gets me excited..
but i think what yonas is saying is.. low revs, massive torque, in a car that pulls you so hard that you dont even care what it revs at lol
Yeah, but people mod their cars so that they can use every last drop of potential. If it was me, I would be tempted to hit 8000+rpm knowing that I didn't have a fuel cutoff at 7300rpm and that my ECU was tuned to 8000rpm and still made an additional 10-20kW up at 8000rpm, eventhough if I was already making peak torque at only 5000rpm :) (numbers are just examples)

Zico, are you posting on Ozhonda from the future?!

my egk24a rev to 7600 rpm only

my 1/4 mile slip speaks for it self

12.2@109.46mph

And Im pretty much happy , Will go deep into high 11s soon

More RPM to rev doesnt mean more power / torque

low rev with massive torque pulls the car so hard already

7600rmp, that's 600 over the stock euro limit, that's quite hectic...

[aaronng]

Stock limit is 7300rpm. With a reflash, it's 7500rpm. So 7600rpm is a good reliable cutoff.

Nice :thumbsup:
More RPM means more power for the same torque though. And if you start to have traction problems with more torque, then more RPM can achieve the numbers too.

[EG5]

yeah 7600 rpm doesnt sound cool enough.

[bennjamin]

12,000rpm or so would sound cool to all the interweb peoples.

[aaronng]

yeah 7600 rpm doesnt sound cool enough.

After seeing vids of the k24a destroked to 2.3L revving to 9400rpm, I don't think I can live with just 7600rpm.

[DreadAngel]

Sif 12K la, need at least 28K where the fun is at ;)

I'd love to rev, but reliability seems to be one of the things high revs throws away...

[z3lda]

theres a 11k b18c daily driven car running around melb. and its reliable aswell. its all comes down to the build and tune

[EG5]

destroke k24 will be good
inline pro 2.6 k series rev's to 11k rpm

Imagine the piston speed
