Re: 89 crx hf engine d15b6 into crx si
I wouldn't recommend it. The CRX Si is about a hundred lbs heavier due to the sun roof and bumpers, so the already slow D15D6 engine would be even more of a dog.
If you're going to do an engine swap into a CRX Si, consider the D15Z1 which comes out of the VX. Or just swap the VX transmission.
