Any-one got a B18C engine in their Ek9


I was gonna get a fresh import EK9 with a B18C engine, and was wondering what other changes to the car would need to be made for it to hack the B18C engine,:nice:

Cheers
 
Non I believe.

Isn't it basically the same engine as the B16b, but with a larger stroke?
 
Hey m8...

My car is stroked to 1.8 - b18c. The only real changes is the ECU and fuel consumption !!! haha

The only things I would advise fitting is an Engine Torque Dampner - Hardened Engine Mounts (spoon etc). This will stiffen up the from end and allow the added torque to be nearly un-noticible handling wise..

Cheers - Andy
 
Haribo1187- do you think it is stroking a ek9, do you feel the differance in power?

cheers:)
 
Soz m8 - cant really give much info cos my car is waiting to be mapped. Ive never driven it 1.8. I would imagine the power will be GREATLY increased, especaialy low down torque.
 
Don't forget though, stroking a B16b will give different results and feeling than a straight B18c swap!!!
 
what would you say is better?:)

cheers

im asking silly questions because im a EK9 amateur,lol, soon to be a owner though
 
i like to rev the hell out of my EK9 all the way to the limiter so it's the 1.6L for me. :D:drive:
 
Seconded. LOL

If you want the 1800cc...get a DC2.

Nothing much between them other than looks, but I can never see the point personally in stroking or changing engine to bigger cc.

But thats just me.
 
A stroker B16 and a B18 are 2 different things...there was one with a B18 in last week at auction, ugly, but that can be changed easily, lol. Larger capacity will generally see more torque.
 
if you stroke a B16B it becomes a B18C of corse it the same it's a de stroked ITR motor lol
 
Stroker kit + new ecu = lots of fun!

I disagree.

The stroker kits are not pistons and connecting rods etc from a B18c.

They are designed and manufactured to be different, otherwise people would just save the money and but B18c stuff instead of the kits.

If you check all the stroker kits available for the B16b, you will see that they are all different in stroke.

im confused,:angry2:

i think im gonna stick to a standard ek9 with slight mods,

:nice:

don't be, the difference between B16B & B18C is the length of the crankshaft stroke, to get to 1800cc Honda increased the crankshaft stroke from 77mm to 87mm (please correct me if i'm wrong) & did some changes to the pistons & conrods to compensate for the longer stroke.

when you buy a stroker kit it comes with all the necessary parts to do the conversion completely.
 
Back to the topic.

Theres a big difference in power and torque between B16B and B18C. The bottom and mid range is very addictive, very torquey. Once in top end, it starts to pull really hard from 6000rpm, which is comparible to B16B @ 7000rpm but much more torque. Even though on paper it's only 163Nm(B16B) vs 178Nm(B18C), not much difference but that doesn't explain the pulling force you feel. JDM B18C 98specR has a massive 190Nm of torque vs 178Nm 96spec. All from a 1.8L

Ok, so don't get confused now but, B16B stroked to 1.8, normally japan uses ITR parts(conrods, crank and piston). Even SPOON use OEM parts to stroke to 1.8, they just further balance it to what they want and brand it SPOON, which is no difference anyway. Don't underestimate Honda's engineering.

This in my opinion would bring it on par with B18C 96spec. Why doesn't it become on par with 98spec? Because, the main factors of the 98spec engine producing more torque is because;

1. 98specR head has been specially ported on the valves area that can and was only done be a specially made tool by honda. No specs were ever given out to public. Valves would obviously be different to 96spec.

2. 98specR ITR used OEM 4-1 headers which pipe sizes were reasonably small which replaced the restrictive OEM 4-2-1 type to produce more torque everywhere.

aftermarket 4-1 headers normally bog down the bottom and mid range, and scream up top. But JDM type R 4-1 header pipes are not big in diameter which has such good VELOCITY flow in ALL RPMS and produce much torque everywhere that many aftermarket headers struggle to beat it. All top tuners know about the type R 4-1 headers. It's the same principal as having exhuast pipes too large over the stock 2.0in. It's like nothing nothing nothing bang vtec something something.

4-1 headers scream up top and loose plenty down low and mid range.
4-2-1 gives gains down low and mid range, sacrificing a bit of top end
JDM type R 4-1 headers gives best of both worlds, except they are heavy compared to aftermarket headers.

Once you've driven a B18C and you jump into a B16B, it also feels like this...

nothing, nothing, nothing, bang vtec something something something.

I really hate jumping from my ITR to the EK9.
 
Hiya guys,

Any of you got a B18C engine in a ek9?


Ya i have a b18c in an ek9.I had a b16b ek9 for a year and a half & got rid of it for a b18c ek9.All i can say is if u can afford it get the b18c.Its alot quicker,goes through the revs quicker,u have way more torque & it pulls way harder than the b16b.Thats just my opinion though.:nice:
