I have a 91 CRX with a D16 and I am planning to put a B16A1 Si-R motor and tranny in very soon. any tips or advice is welcome!!! I have not done this swap before so a lil help would be great!

 

A b16a1 was never made..

You are talking about the b16a

Are you doing obd1 or pre obd0.

If it's obd1 you will need a jumper harness ( I think), but everything else is straight drop in. You prolly will have to remove your front mount on the crossmember and do some slight frame rail denting for the alternator pulley to make cleareance. Other than that, it's a straight shooter. You will also need the sub-vtec harness. If it's obd0, Either make one yourself (EASY as pie) or buy one from hasport. Anyone feel free to chime in a correct me!!

 

when u have the front end apart put in the header their a b*tch to put in once the engine is in. and most the time they won't pass ur cross member.

 

Will I still need the jumper harness if the ECU is comming with the motor and tranny? the web site said b16a1 my bad I didnt know.

straight drop in???? mabey after mounts, shift linkage, throttle cable, and axles. OP do a quick search and check out the FAQ page. All the info is there, you just have to look.

 

Does any one know what axles I will need to use, as in what will fit and so on?

 

well u need a cable clutch tranny from a 90-93 integra and for the passenger side axle u can use a 90-93 integra axle or a 99-00 civic si axle. for the drivers side it depends what intermediate shaft u get. i believe the S1 shaft is an inch longer than the Y1 or the other way around someone correct me if im wrong. but if you use the shorter of the two shafts, then u need a 90-93 integra axle for the drivers side, but if u get porked with the longer one than u need a drivers side axle from a 86-89 integra.
