**cuongn** · 23-11-2007 06:24 PM

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.

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

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.

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

vtir 4

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)

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

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

) plus your in it for the win

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

and pain

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
