B16B vs. 4A-GE (BT) study of the facts and conclusive

Now before you think this is just another Toyota vs. Honda you could be fighting disappointed.I have used the search function, but the subjects come up with answers like Honda is the best, that's why!

The purpose of this chapter is to find the differences between these very similar engines.and why are they so different?

Now we all know Toyota () AE111 4A-GE (asphalt) 20 valves (three intake valves per cylinder) (a total of five valves per cylinder), introduced in 1995 and continued until 1998, 1.6l (1587cc), a sky high compression ratio of 11:1, individual throttle bodies, OEM (factory) tubular exhaust manifold (extractor), lightened flywheel, six-speed gearbox C160 models later this beautiful beast manages 165 PS (163 hp 121 kilowatts) at 7,800 rpm with 162 N � e (119 ft � lbf) at 5200 rpm torque. which is very impressive for a naturally aspirated 1.6l.


but turn our attention to the engineers at Honda, and the epic and the creation of the unimaginable dreaded B16B-R. However, this engine is based on a simple design DOHC 16-valve with a displacement of 1595cc (1.6L) (essentially an expanded version of a B16A), a compression ratio of 10.8:1 and the people in charge of the project Honda B16B to successfully extract 136 kilowatts (185 PS, 182 HP) @ 8200 rpm and 16.3 kg / m (160 N � e, 118 ft � lbf) @ 7,500 rpm. Now, the point of view of 1.6 ', if it does not seem to mind much you B16B has increased the specific production HP per liter than 360 Ferrari.



Now to my question and the subject of all this information is that
why one of these apparently similar, eg both are DOHC / valve Twin Cam Multi 1.6 with the internal specifications grotesque example Bore x stroke watching two engines:
B16B bore x stroke = 81.0x77.4mm

AE111 4A-GE bore x stroke = 81.0x77.0mm
Also ......
Both use their versions of the technology of variable valve timing control.

now on paper the 4A-GE looks like a winner with all the plants equipped race spec parts (such as tubular extractors and ITB for a road car round the CR 11:01 certainly looks like something out of a group or A catalog JTCC motor racing)
