The head will bolt up but you will need to make a few mods for it to work properly. The trans will bolt to the block but you will need to custom make a transmission mount and bracket for it to bolt to the chassis. Plus you will need a newer clutch kit from the 2000 model to mate to the transmission year since the input shaft on the trans has a different number of splines than a disc on the early 88-91 civics. The head swap would be worthwhile but the trans is more work than it is worth.
