Q. I want to swap a my 91 CRX HF D15B6 engine to a larger/faster Honda engine? Is it complicated and hard? What do you need to make them fit?
Answer
Well its not hard at all. First do you know how to work a engine hoist? 2nd do you know how do a timing belt. 3rd do you feel comfortable about remove an engine?
Simple remove your D motor and replace it. SOHC/DOHC ZC or what they are D motors are direct bolt in no wiring needed unless its a Vtec. For more info on that.
THEZCR.com
B-serious need motor mounts, axles, shiftlinkage same as above. I belive you need a different brake hub. LS motors 1.8L B20 2.0L non vtec need no wiring but you need to convert to OBD1 Vtec motors need more wiring

K-serious lets just say if you ask this question you can do it on your own that goes H motors.
What I suggest?
I done many ZC motors before simple cheap the SOHC ZC has about 130HP in a car that weighs 2000 you should be 15.0-15.5 in the 1/4 with a decent tire and traction lower 15's. Boost on this motors a safe 7-8psi tune your 13's friend will show.
SOHC long block $400
ZC non lsd tranny $150 LSD $400
B-serious are great you can get a B16 swap down for less then $2000 if you do it yourself. 14.7-15.2 1/4 GSR take another .20-.30 off ITR motor is a monster .40-.50 off. All these times should be on your stock street tires. 200whp in this car will net you high 13's range.

Answer
Well it isnt as simple as you make it seem, first you dont slap them on and woot HP.
You need fuel upgrade, fuel pump since its a 17yr old car, larger injectors, you need to place the map sensor and brake booster somewhere and must important tune!!!!
Still want to do it link below:

Look into OBD-0 ZC SOHC motor and trans ecu it net you 130 crank HP with a good intake header and exhaust 140-145 crank HP since the D15B2 isnt taht good, look at hmotorsonline.com for the motor
