1.8l B6 swap questions.
 
Few questions.
A: will it work on a FB subframe?
B: engine mount modifications?
C: will it fit under the hood?
D: running exhaust to oposite side.
E: will this interfere with my steering rack (read a build sheet saying it might)
F: and lastly. Wiring harness, and any of the other stupid thinks. Like a throttle cable being a Half inch too short.
Car is a 85 GS.
Thanks.

I am currently doing this same build ill try to help with what i know so far

A: no the steering links will be in the way of the oil pan(I did the fc swap to correct this)

B: Yes it will fit but its very close fit (mine I might trim the hood support bracket around where the oil cap meets it)

D: my swap the exhaust starts on driver side but transfers over to the passenger under the tail of the transmission

E: as long as you go over the rack you'll be fine(mine goes over because I used the miata transmission with a rx7 tail housing that way the transmission mounts where the same also same drive shaft length)

F: Use the miata throttle cable for the 1.8 its long enough. Wiring... well the harness is U style harness meaning one side goes threw the firewall left side and right, a hole or modification to the wiring would have to be done.

I have some photos if you would like to see.
