B16a Ver 2

what gives the second version of the b16a a extra 10hp from the first b16a gen 1 cause the first b16a (cable trans) has only 160hp when the second gen (hydro trans) has 170hp, i know the compression is different but its only a .2 higher and that can't make a exta 10hp

read up on the specs of these engines...there are minor differences that will give that extra 10hp

Its basicly cams, ECU and compresion.

But it donst matter as my car is still faster than yours.

hehehehe, i know your car is fast BUT i wonder how did they get a extra 10hp from the version 2 b16a

Basicly they just retuned it a little.

By 92, Toyota had the 160hp Super charged 4agze and the 20valve 4agze. Nissan were working on thier own version of VTEC and mitsi had Mivec.

So I think to stay ahead and to try and make for the extra weight of the 5g and 6g Honda did a retune.

The compresion was raised a little and more aggresive cams were used. As well as a New ECU, with better mapping ablities and new fuel curves for the differnt cams. inlet manifold and head porting I believe remained the same.
They also use a differnt Dizzy and O2 sensors, like they were getting ready for OBD II.

Bascily if I swapped the head on mine and the ECU I would also have the extra hp. But I think Iv got a better and flatter torque curve.
The extra peak 10hp came at the expense of a lot of low end power.

so if get your hands on a b16a version 2 head and computer you will gain that extra 10hp
