B16A, 180 whp possible?


Depends on the readings of dynos in certain countries.

Our stock FN2 Civic Type R(200bhp) makes 150-153whp stock. Thats about 25% loss and is what our dynos all generally read in AU.

180whp is like 230bhp in our country.

Most mild B16a make only 120whp. Thats just our dynos.
 
from my experience,
b16a2 engine with ctr cams,pct pistons,ITR intake & TB + header + cai + 2.3" tubing, piggyback = 170++ whp with 97 octane fuel
 
its possible but still not cheap, actually very expensive

i could get my friend to remap and play with my b16a2 to achieve 210 bhp peak but i told him and he wouldnt have dont it anyway that overall band and driveability was more important to me, then again i could use a set of his designed cams (£ meant i couldnt afford at the time) and would have good bump in power right through the band at peak would hit 210bhp maybe couple more (i run stock b16a2 cams and my motor is under cammed)

put it simply, a cleverly constructed and mapped car with say peak of 190 bhp for example could be quicker than not so clever car with same motor with say peak of 200bhp

Very very true...the only readings I would truly trust are Dyno-Dynamics even if some people consider them conservative....They are at least consistent from dyno to dyno!

My B18C6 ITR with simple breathing mods & mapped is now at 164whp....no massive peak figure here...but ultra realistic

To get my car to a Dyno-dynamics 180whp would require considerably more work & expense IMO...

Being that a B16 motor is a bit short of a B18 in terms of power/torque purely due to its lower capacity then the task is more difficult...

Id agree that it is certainly achievable, but would almost certainly mean that the engine would lose tractability at the expense of a good peak BHP figure...

Do-able...Yes
Viable...Not so sure

Much easier to start off with a B18 IMO

We are also affected here because the dyno is located like 3000 feet (or more) above sea level. So 180 whp for us is like 190 - 195 whp for USA dynos, and I think UK dynos also. :nice:
 
Have you thought of B16b rvm?

I have 175whp with stock cams, only ITB (42mm), ITR 98 spec header, and tuned with Hondata. I use to drive on the road before the car got too hard core, very streetable.

*edit* Fuel rail is stock, injectors are stock, fuel rail stock, valves, ports, (intake and exhaust).

Although the dyno is close to sea level, the circuits are a varying heights and I have not noticed a difference.

The ITB were adapted from 4-AGE Toyota (silvertop), it is actually surprisingly simpler if you can get the black top version, as the intake ports are very, very close to being the same. You pretty much only need an adapter plate and you're away.

I don't know whether you coud get good results on 95 octane though, my car is tuned with 98, and I use 100 octane biofuel with 10% ethanol, its fantastic.

I am trying to sell my B16b cams if you are interested, they would be a good start. Infact I could probably source all the parts needed to upgrade your B16a to B16b, or pretty close, if you wanted to go down that track. I could even send you my B16b ITB map for the Hondata!

After the rebuild my motor just went through with lots of new parts added (but some are secret :p) I'm chasing 200whp+.

Good luck!
 
Imho, why go for a B16b and not the B18c instead if you think of going that way...since the only difference is the crank, pistons and rods. Price wise it's also a small difference. Way smaller than what you'd have to pay for mods to get just as much power and torque as a B18c.
 
yeah well one of my friends has an ek4 with a huge amount of tuning parts in the engine it made 184whp last month he is using skunk2 pro2 camshatfs, toda header, edelbrock manifold, supertech valves , retainers, and valve springs, so yes much spent but yes you can achieve it... the quiestion is how long will it last:)?

high comp pistons, big cams,mill/port head, tb/im, high octane (110+) fuel + tune = 220whp.

Its easy to make car with a lot of power, now weather or not it will be streetable is another story ;)

what do u guys think the whp figures can be achieved on 91 octane? where i am at, we got shitty fuel

This number is also my goal even if I'm being optimistic I'll give it a go :D
