The beauty of the pc controlled ignition is always that spark progress is usually metered out at the proper time. Due to this K series engines are issued with Significantly bigger compression ratios within the manufacturing facility (as higher as eleven.7:one in JDM K20a engines) than before distributor dependent B-series engines.
In the end, don’t neglect the Honda B20 timing belt. Untimely failures can and do come about nonetheless it isn’t terribly common.
Though the B is not any sissy, with racing illustrations standard eclipsing the 1,000 horsepower mark and street builds sneaking up on unsuspecting V8s, it remains a toddler in the eyes of the aftermarket: their toddler.
The very first thing you must contemplate could be the finances. The B-series had a 12-calendar year creation run, and plenty of cars and trucks driven by these engines can now be present in breakers yards.
Although the B20 engine is simpler to change and is best for colossal ability gains, the B16 is a fantastic alternative for those who want to enhance ability concentrations.
Even with a few uncomplicated bolt-on pieces, you could strengthen on the manufacturing facility electrical power figures. You will find close to-infinite possibilities On the subject of tuning the Honda B16 engines.
“We took the inventory car or truck and put a MoTeC ECU on it and we turned it up,” he states. “It was straightforward to incorporate a hundred and twenty horsepower with out touching any Section of the car, in addition to Placing a computer in it and about 30 percent ethanol in it.
For this engine we observed that we could run up to 10 levels of progress (in crankshaft levels) about the intake camshaft even though continue to preserving sufficient valve to piston clearance.

The real difference lies in I-VTEC’s cam phasing abilities. Even though VTEC allows the engine to mechanically engage a distinct, extra intense cam profile in a predetermined RPM, I-VTEC can also actively advance or retard the camshaft additionally or minus 50 degrees.
At this time, you’re possibly considering someplace from the region of a hundred and eighty horsepower with a superb remap. It’s nonetheless possible for making a whole lot extra electricity, although.
