the previous owner of my em1 replaced the b16a2 with a b16a3. he put some kind of aftermarket im on it. will it still have the same power? it doesn't seem to have the power it should.

B16A2='99-'00|Civic Si (EM)-USDM-160hp@7600-111tq@7000
B16A3='93-'94|del Sol VTEC-USDM-160hp@7600-111tq@7000

Only difference to my knowledge is that they either converted your car to OBD1 or they simply changed the bottom block and kept the old head

Same engine pretty much.....

all second gen B16A's had the P30 intake manifold on it, it is a kiss *** design and makes more power than most aftermarket models

They also had the Obd2 B16A3 in the 96-97 Del Sol Vtec. But more that likely its just converted to OBD1.

scott_turner

from what he told me, he swapped the dist. nd injectors over to obd2. i don't know what intake manifold it is. I do know it has a p2T ecu. i had to bypass the cfk..it has a greddy header on it, would 3" exhaust help?

pics?

it should have bout the same power except there could be other things.. some motors come gifted and some motors come bad..it sounds like i think you need a dyno run to c where its power is and then dyno tune it again after a few more upgrades to c how much better u do..oh yea bigger piping will help out pretty good.. better air flow but remember, you need back pressure to so be sure to put a muffler on..

hmonguy918

hey maybe it could also be the ecu too.. are u running on limp mode? is check engine light on? if it is it could be limp mode thats laggin u down..

scott_turner

no cel..i am going to see if i can find a place around here to dyno it. I will take pic of im, maybe someone can tell me what it is

Deetz

Still they same engine...even the dizzy, it's internally the same with the same wires even. Swapping plugs could be done in minutes....otherwise, there is really nothing to convert

It's the ecu that actually dictates the obd, but doesn't really play much of a role in 2nd gen B16 engines themselves

scott_turner

any ideas..

There are no OBD2 B16A3s, '96 - '97 Del Sol VTECs got the same B16A2 as is the one found in the '99 - '00 Civic Si.

That looks like a Aebs

scott_turner

are they decent?

Deetz

they are ok, but a little on the cheap side as far as build quality goes. I know if you over tighten the throttle body, the mounting area's will split/crack

hondaluver19

You are right. I was almost positive there was when i was researching these a few years ago. But after researching again.... there isn't one. Except for one website that i believe is unreliable. Thanks for the correction.

hondaluver19

x2. never used one or knew anyone that used one.

dk=gsr

from what i know the b16a3 had a longer gear ratio tranny like the GSR's.
there 2nd was longer than most b16 trannys.
correct me if im wrong.

dk=gsr

but besides that the motor and everything is the same.

dk=gsr

and that intake manifold looks like an AEBS intake manifold.
