    ^^ He's correct. You'll need to swap in either DX or Si hubs and axles.

    you don't need to swap anything to put the Si transmission in the HF - all of the 88-91 axles are the same at the transmission end - the difference is at the hub end where the CRX HF and Civic STD have the smaller hubs - just put the transmission in and install your HF axles

    Your stock flywheel and clutch should work fine. 90-91 interchange freely between all trim levels. The axles are the same on the transmission side, so you don't need to swap either them or the hubs.
