Hello,

I was wondering if anyone has detailed information on what is required for a B Series Swap into a 91 CRX Si.

Thank you

 

Pretty sure there a number of threads out there with this info, including the sticky up top, but i'll make a quick one off the top of my head anyway.

- any b series engine. Make sure the drivers side post engine mount is from a 90-93 integra or ef SiR
- b series cable tranny, or hydro version with conversion
- new clutch (flywheel optional)
- new rear main seal
- new themostat
- new timing belt
- new cap, rotor, plugs and wires
- b series engines swap mount kit
- 90-93 integra axels, including intermediate shaft
- ef SiR shift linkage, or custom swap linkage ie. Hasport
- 90-93 integra throttle wire
- 90-93 integra rad hoses, and rad is a great option too

That should cover most of it, i would cut any corners if you want a quality swap

 

Google

 

If it's b series VTEC you'll also need to wire up VTEC and the knock sensor. You'll need the corresponding ECU as well.

PLEASE click on the Tyson's FAQs sticky at the top of the forum. There's a section dedicated to B-series swaps.

Carefully read information in those threads, and then return to this thread with only specific unanswered questions.
