HONDA VTEC B SERIES ENGINE GUIDE AND SPECIFICATION
Tuning a vtec engine equipped car can be very interesting.
A vtec engine is famous for producing high power without the use of any forced induction.
A Vtec engine is simply a high revving monsterous machine.
Eventhough im a ‘turbo’guy, i do have an interest on Vtec engine, especially the B16b engine which produce 185bhp with only 1.6 liter of displacement without the aid of a turbo or superchargers.
Yes, its pure engine power.
Another thing that i like about Vtec engine is the ability to mix and match the engines.
As long as the engine falls under B series, it is basically inter mixable.
My favourite combo for this matter would be a B20B Block from The Honda Crv combined with a B16A or even a B16B head.
Swap in some performance cam and few tuning here and there, you’ll be smilling all day long on this monsterous machine.
A 200bhp B18C TYPE-R EQUIPPED INTEGRA DC2 TYPE R
A 170bhp B16A EQUIPPED CIVIC EG6 SIR
A favourite Honda car of mine is the Eg6, Ek9 Type R and the Dc2 Type R. With a race tuned engine, these machines are exceptionally fast in the touge and circuits.
And if you notice, all the car that i mention is in the 90′s where they only bother on producing maximum power without even thinking of fuel consumption and emmission.
It is the glorious day of car modification.
Eventhough all this vtec engine had been around for more tha 20 years, it is still one of the favourite engines to be worked on.
Especially the B16 and the B18 series. So i would like to share as much info as possible on the Vtec B Series engine.

Note: This engine uses the same block as the Integra Type R, which is taller than the B16a block, but with a crank the same stroke as the b16a. It uses longer rods to accommodate for this, which is why the Rod/Stroke ratio is higher than a standard B16. It is basically a ‘Destroked B18C Type R engine’
