ok i wanted to know how i can tell if the b16 i bought was originally an automatic or a manual. Kai? any thoughts?

 

anyone? also it is the 1st gen jdm...it came with a j1 5 speed but also came with a ecu for a auto...just wanting to know if my engine was for the auto or 5 speed. i hope there is a way to tell. I know the cams suck neways...bought new ones, but it is the compression ratio want to have from the 5 speed version B16a.

 

I don't think there was an auto CRX SiR.
Maybe they sent you the wrong ECU with it.

 

yeah they def sent the wrong ecu but remember the B16a 1st gens werent just in crxs. jdm integras too

 

the motor would not be designed to work with a specific tranny. The ecu is what would be different, definetely need to get one for a manual. I also don't think they made a b16a with an auto, but i'm not sure on that. but anyways, a motor is a motor and is not "designed" to work with a specific tranny.

 

ACTUALLY the B16 that came with an auto tranny had smaller camshafts and not as much compression ratio :db:

 

prove it. what would the engine code be then?

 

the engine code would be B16A

and yes they had automatics, and yes they had a slightly lower hp.

 

but if he is replacing the cams he could use ones with a higher lift which would also raise compression right? then it wouldn't matter if it originally had and auto or manual tranny

 

it would also raise hp
