Ok... I'm new and I'm 16 and my first car is a '90 Honda Civic HB, I have recently purchased a '94 Si HB with a B18C1 and am planning to swap.
Questions:
1) It needs a new wiring harness b/c the Si was involved in a garage fire but the motor/trans. is pretty much perfect. Where can I find one for cheap?
2) I disconnected the radiator and drained the fluid, should I flush the hold radiator before reinstalling?
3) A majority of the rubber pipes were melted in some parts, can I transfer the pipes from my D15 motor?

Thank you for your time and replies

 

1) Use the harness from the '90 and modify as needed to work with the B18.

2) Might as well flush it while it's off.

3) Just find out which ones you need, and get new ones. Dont be cheap.

 

1) When you do the swap you do modify your current harness to work with the B series engine. I'm pretty sure you have a DPFI car like mine (89 hatch) and you have to convert it to MPFI and a couple other things.

2) Definitely. Don't see why not.

3) New pipe isn't as expensive as replacing a warped engine block if rehashing pipe goes wrong. Braided steel (Like oil lines on a turbo) is cool too if you wanna splurge!

I was going to just copy and paste his answer since I agree 100%, but I wrote some extra so you can feel a little bit better about trusting that opinion.
