yes i know which cars they come out of...but what about differences if any.

 

i think the a3 is off the del sol and the b16a2 is off a Si...also the A2 has a little more torque

 

from what ive read all the specs are the same...and like i said, i know which cars they come from. i wanted to know if there was any other differences like redline or if one can take more abuse than the other or where to purchase a b16a3 cause i cant seem to find one anywhere.

 

The difference is the a3 is obd1 and the a2 is obd2. That just means the a2 has more sensors on the motor.

Essentially they are the same exact motor.

 

so would it be harder to put a2 into a non vtech del sol than a3 since the a3 is already obd1?

 

yes auburnBoy nice job on your reading comprehension skills. you can always take an a2 and tack on all obd1 stuff too, but its more work.

 

so was the a3 only usdm? is that why i cant find on any jdm motor site?

 

jdm is only B16a no a2 no a3....i believe the b16a3 redline @ 8200 rpm on del sols...and a2 is @ 8000 but it could just be the ecu ??? and yes its USDM on 94 model del sol's

 

from what i read on spec web sites its 94-95 models

 

and yes your right about the no 1,2,or3 on the block. but the jdm b16's are sir, sirII,xsi,and B for type R right. and the sirII is the same as b16a2 right? and the xsi is from an integra...so wheres A3?

 

The A3 is most similar to the 2nd gen b16a that is OBD 1 and has the hydro tranny. All are very close. The only thing that differentiates them is the OBD level and a cable or hyrdo tranny.
For example:
USDM Motors- have slightly lower compression and usually a little less hp/tq than jdm/edm motors due to emissions standards
A2: OBD 2B(OBDII A is 96-98 in the 96-97 sols) w/hydro
A3: OBD1 w/ hydro
JDM/EDM motors
1st gen B16a: OBD 0 w/ cable tranny
2nd gen B16a: OBD1 w/ hydro tranny(similar to b16a3)
XSi b16: OBD 1 w/ cable tranny(at least according to most swap sites...some don't even list this motor)

 

i am dealing with this also, all the torque specs the same?

 

All are close (within ~1 ft/lb)

 

gotcha, thanks

 

jdm motors have more hp/trq than their usdm version, as we all know...but does the jdm del sol b16 have more hp/trq than its usdm version?

Yes. The JDM 2nd-generation B16A has 168hp @ 7800 RPM. The USDM B16A3/B16A2 has 160hp @ 7600 RPM.

 

30005 - B16A 92-95 (SiR-II)

The 170 number is PS, not HP.

 

1 ps = 0.98632 hp

 

here a little searching and heres what i got out of it. pretty interesting.. tells the car and motor and all the hp and tq specs..
