The car runs and drives, the wiring inside still looks bad. When I started this build I didn't know where to start and the EF/CRX chassis has some specific things needed that other chassis's don't need so if you are doing a similar swap and have any specific questions let me know I'm glad to help someone else out.

All the work I did myself except some tuning help from a local honda tuner in SoCal.
Setup:
1991 Honda CRX Si Chassis
Hasport K-Swap engine mounts
JDM K24A from any jdm importer
Installed a K20 oil pump
Original RBB intake manifold
02-07 Accord throttle body
Made a cold air intake with a Blox Air Filter
EP3/RSX Base 5 speed Transmission got from a Honda salvage yard
Installed a LSD into the transmission
Honda Element ECU with Hondata KProv4 installed onto it
K tuned conversion harness for CRX
K tuned wire harness
Hush performance cable to hydro conversion kit
Hush performance radiator support bracket with Volkswagen rabbit radiator (Kinda crappy kit tbh)

I'm probably forgetting alot of stuff but you can see everything in the pics.

Congratulation to your engine-chassis-marriage. Not an easy one, even if the hood is wider of the B-series owned one compared to the D-series owned ones.

Would be really interesting if you measure the ground clearance among the oil pan, the hood clearance above the valve cover and the engine inclined vertical angle. Also I am interested if the horizontal alignment of the engine is really parallel to the ground. For my tile-setter eye it looks like there is a slight offset compared to the wheel housing.

hi! i’m starting a my crx k swap, it’s a complete shell. no interior no nothing, and i have ZERO idea where to start lol! i was wondering if i need the dash harness and main cabin harness and then just the ktuned adapter harness for the ecu and then the obvious engine harness ? as well for my firewall i only have a break proportion valve and brake booster, i don’t plan to run ac/ps or heat because it’s gonna be a summer only car and the heater core and everything for that is gone.

I’m not sure what my ground clearance is, but it’s pretty low to the ground. I used a K20 oil pan and it’s a bit smaller than the K24 oil pan to help with ground clearance. Also the K24A does not fit under the hood, someone makes a hood that does have enough clearance I just haven’t bought it yet.
I used K-Tuned PS/AC delete and it also relocates the alternator lower on the engine. I did have to use a traction bar as the oem front crossmember is too big. I don’t think the alternator fits in its normal spot, I think it has to be relocated.
