Hey I need some tips on doing a B16 swap into an 87 CRX Si....this is my first B series swap so I just want to know if there are any details that must be taken care of and about wiring....what ecu to use or what harness....any help is greatly appreciated...

 

Check out http://www.hasport.com

Also Sport Compact Car magazine did a detailed layout of this swap about a year ago.

 

scc was nov 01...i nearly have finished a crvtec into 87 si so know a few things...you can go with the b16a but need mounts and throttle cable adapter and shift linkage and axle and spindle changes, but it is hella power to weight ratio, particularly after removal of sunroof & motor, rear wiper & motor and bumper supports.

 

My 85 CRX Si weighed 1960 with a B16. It rolled ITRs.

 

Thanks for all the tips guys....

 

I did a B16A swap on my 87 CRX. Its faster that my previous 4G Civic VTEC.
I have some pictures on my website.

Good luck with your project

 

ill be doing this same swap soon i have a few questions

are there any other options for axels besides hasport?
87 crx SI, shouldnt be much different than wiring a 88-91 si?
any other shift linkage options? i know on 88-91 you can cut and weld to make it work
any cutting or removing of anything?

 

you dont have to get the axles from hasport but their site tells which applications dep on tranny you choose...

yes, you can weld up the linkages, i was lazy and just bought those from hasport

i got the throttle cable bracket on intake mani from placeracing but you could do your own if you know anything about metalworking

ummm, i forgot your other question...

 

oh yea, wiring...you can use most of the si wiring but have to look at the pinouts and may have to do a little customizing so you gotta match
