In 1989, Honda introduced the main technology B16 engine towards the marketplace from the Integra XSi, along with the CRX SiR, which later went on to beginning an extra six generations in the course of its eleven-year lifespan.
Along with DOHC, it had been also the very first engine to aspect VTEC variable valve timing. As certainly one of Honda’s most defining characteristics, VTEC allowed the B16 to own dynamic efficiency attributes greater while in the rev assortment. VTEC optimized the B16 and compensated for the reduced displacement.
Honda was capable to realize this sort of fantastic horsepower for every liter by employing their VTEC technological innovation, along with having pretty substantial rev limiters ((RPM*Torque)/5252 = Horsepower). VTEC performs by utilizing a person camshaft profile for minimal RPM, supplying superior torque and outstanding drivability, in addition to a camshaft profile for top rpm that includes a higher elevate and more time duration. The lobe profile is switched depending on load and RPM to increase power output at superior RPM.
It absolutely was a brave feat for a stock engine, Specially looking at it would make for an immensely trustworthy and handy day by day driver.
With regard to valve lift, the B16A2 engine has a maximum elevate of nine.0mm for your consumption valves and eight.4mm to the exhaust valves. The valve lift and length are adjusted according to the VTEC engagement, which happens at 5600 RPM.

The stock bottom holds about 300 hp at the wheels, from time to time a little more, but it is better to not force towards the limit and purchase forging below compression ratio ~9. Moreover forging you will need to invest in H-beam connecting rods, reinforce the block, get ACL liners, ARP connecting rod bolts and studs. You also require a complete rework on the cylinder head, however it is far too highly-priced and they are engaged in this kind of do the job models.
The Honda B16 engine can be a remarkable piece of engineering which includes attained its place Among the many finest within the automotive planet. Its combination of substantial-revving energy, VTEC technology, and considerable aftermarket support causes it to be a top choice for fanatics and tuners.
When it is actually enjoyable to contemplate building up a major-electric power turbo B16 engine, it can be crucial to initially consider exactly what the finish objective of your respective Construct is. Are you currently shooting for just a everyday pushed B16 Civic with a certain amount of further oomph?
The effectiveness metrics of the B16 engine are very well-documented and have already been validated as a result of various exams and opinions:
Obviously, the level of horsepower they could make relies upon entirely on price range. Don’t count on to make any much more than 250-300 horsepower with out expending a sizable chunk of alter.
While Honda’s B16 will make a fairly tiny amount of torque, it revs pretty superior, and horsepower is just an equation of torque and RPM. The end result is often a peak of 187 horsepower from just 1.
